Why I still have unlimited data

Nexus 4: 3 years later (2015)
With this being 2015, cellular networks have changed quite a bit. The Nexus 4 has support for GSM/WCDMA and LTE unofficially. While this maybe appealing, let's actually get into why this phone may not work for you. I've been using this phone in the United States on T-Mobile, while I found no connectivity problems, your usage may actually vary. For LTE the Nexus 4 only offers unofficial connectivity on AWS (Band 4), while this maybe a limitation for AT&T customers outside of AWS who want a slice of LTE pie, it will be more than enough for a T-Mobile user who lives in a AWS LTE covered area. But why didn't I mention UMTS/HSPA? For the most part, UMTS/HSPA seems to be congested in most of the areas I've tested and it isn't better on PCS either. But don't let my mileage stop you! Since I'm using T-Mobile in Columbus, Ohio the spectrum offerings are PCS EDGE 5 Mhz, PCS HSPA 10 Mhz (DC-HSPA), AWS HSPA 5 Mhz (21.1 Megabit downlink), and AWS 15 Mhz of LTE. While 15 Mhz is being used for HSPA, it is still less spectrum efficient than LTE. Enough of this LTE talk. For anyone who wants to use this device on AT&T, you will most likely be restricted to HSPA+, which is enough for most users. Wi-Fi however is a different situation. The Nexus 4 supports A/B/G/N. However, the Nexus 4 only has support for 20 Mhz wide channels. But what does that mean? Simply put the Nexus 4's maximum link speed is limited to 72 Mbps. Let me remind you how different this is to other devices. The HTC One X can have a maximum link speed of 150 Mbps. But to sum of connectivity, I'd personally recommend using T-Mobile if you need LTE. However, this isn't to discount AT&T and their unparalleled coverage to T-Mobile. Also, The Nexus 4 will not be able to have LTE in some areas where T-Mobile is going from 2G-LTE. Quite a few sources say this upgrade entirely skips HSPA+ and uses Band 2 for LTE, which the Nexus 4 does not have.
For ROM and kernel I've decided to use Franco Kernel and Chroma ROM. With this being a Nexus device, the developer support for it is almost unimaginable. So I needed something to put on it and those were the two I've seen first. Performance is no lose for the Nexus 4. No sort of slow downs ever on this device. Also, given that in Android 5.1 ART has also seen a significant improvement in application launch speeds and performance means this device won't skip a beat. But, this isn't to discredit any other devices, it is with its flaws. For example, navigating in applications mean in settings can be a little irritating dealing with some unsmooth scrolling and long loading times. However, if you previously used a device with a faster chipset, the performance gap will be noticeable. Another thing to consider is the phones LPDRR2 RAM, which is slower than newer devices and consumes more power. But that didn't stop my Nexus 4 from leaping through task switching. So how can it do it? One of the biggest key factors why the Nexus 4 can still be usable in 2015 is the Quad Core processor and 2 GB of RAM. Even if the device isn't using that RAM, it still makes task switching and multitasking possible. Processor wise the Nexus 4's 4 Krait 200 cores seem a bit puny to today's standards in benchmarks. But this is why benchmarks only show how future proof a device is to an extent. See, my philosophy on benchmarks is that they show how long the device can be operable with the latest OS until the performance is unbearable. With that being said, the Nexus 4 is not the strongest in benchmarks, which is fine.
As a general synopsis, I love this phone. However, some things I did not mention were the camera and battery life. Both are equally poor. Also, the testing on this device was done with a Nexus 4 Rev 11 model in black. So will I recommend you pick this device up? Maybe, but as a device to give to your kids or to someone who is entering the world of smart phones? Yes. The Nexus 4 3 years later is still an excellent performer and I see that continuing through 2016.

Services over Quantity.
Fixes for performance! Windows edition!
1. Changing your pagefile settings. When getting a new laptop that is based off of Intel Silvermont architecture, I knew my problem wasn't CPU related. (Benchmarks confirmed this) So, I had this issue when changing workloads, like going from doing homework to playing a game. I would be using LibreOffice and Google Chrome for my school work (I am a online student) and my processor would be running somewhere from 1.8 GHz with only 2 cores having usage above 50%. So that eliminated CPU issues and I then went to see what was using so much of my I/O. I then realized it was the pagefile and superfetch. After manually changing my pagefile settings and disabling Superfetch, my performance remained stable when switching workloads.
2. Stay with the same antivirus. After using Microsoft Security Essentials for years on Windows 7, I wondered who could provide the same or even better coverage. But, after switching antivirus, I noticed that every time I had to re-install all of my Metroapps. VERY ANONYING. So, I am going to make this recommendation that you don't change antivirus unless there is absolute reason to, at all.
3. Stop using PC maintenance programs! Frequently, when I go to fix someone's computer I see they have some sort of maintenance program and it claims to have found thousands of errors within the system. Well, in an attempt the scare the user, the program will look for temporary files (Mostly lots of small files) and look for registry "errors". While I am not going to tell you what is best for your system, I am going to tell you what was optimal for me or others. But, in actuality, you don't need any PC cleanup application unless it is CCleaner. Why CCleaner? It actually looks for temporary files and is proven to do its job properly, and at no cost.
4. Remove unneeded files and programs. While this is confusing and because a PC can have so many different configurations, this may or may not actually work for you. Unless that application uses a service or is always present in RAM. While all PC users should always run some sort of cleanup. It may actually not be needed as frequently. A PC with a SSD should always be checking for TRIM and a PC with a mechanical drive should defragment their drives. Always remove bloatware, always remove anything you don't use. If it is difficult to remove Google it, if it comes up as being essential, keep it.

Cherry Picking Your Setup (ROMS and Kernels)
This happens at least once a day, there is that one person who asks "What is the best custom ROM/Kernel?". Most likely another person says a ROM and says why they feel others are inferior to it. While other ROMs may be in its Nightly phase, do not let that discourage you from trying out that ROM. Some ROMs are in their Stable forms and still operate like a Nightly. That is not bad! For example, for the HTC One X, most AOSP ROMs are based or use something from CyanogenMod to make the ROM even boot. But my point is, every ROM is different. Every kernel is different! Some ROMs use Linaro Toolchains, some are based on a stock kernel with memory enhancements. Plus, everyone has their own particular setup that they run that they like! I use M-Kernel on Carbon ROM with all F2FS on my Nexus 7. Plus, I am at a -125 MV undervolt, will everyone like that setup? No, some over clock their devices and some under clock their devices. So it is up to you to find your perfect ROM/Kernel setup.
So I will help you find your perfect setup. First things first, do you want to be on KitKat or Jellybean? The reason I say those two is because the best compatibility between modern applications comes to those two Android versions. So you chose KitKat, remember most KitKat ROMs are in a nightly phase and may stop working or have some features that do not work at all, so if you need features such as Bluetooth or Camera, remember bugs can come! Remember to download the latest release your ROM developer has, so if it is release 4.4.4 on July 28 2014, download that version. Now you have a ROM, find a custom kernel that your device will support. Some kernels do not allow overclocking and if you are just finding your setup, do not overclock your device, yet! You are just finding what you will like! Now download the Google Apps package for your ROM. If your ROM is based on 4.4.4 download the Google Apps for 4.4.4 and if otherwise, download the Google Apps for that Android version. The latest as of this writing on 7/29/30 is 5.0.89 for Google Play Services. Now you must flash that ROM and kernel. I usually flash my ROM and Kernel first to enter information such as APN info and disable vibration or other unwanted features and then reboot to flash Google Apps. Tinker around with your setup to see if you like it or not and if you do not, then try another ROM and repeat. Comment or find me on Google+ for any questions.

Why I support BYOD
After moving from Washington DC to Columbus Ohio, I have noticed quite a few differences in how ISPs treat their customers. In Columbus, for high speed Internet, you primarily have two choices. One being WOW! and the other being TWC. Most people don't switch Internet service providers this fast nor do they always find some huge flaw in the service being provided. So in my almost 50 days of living in Columbus, I'm going to be telling you how I've ended up on TWC from WOW! and how problems like these can be solved by allowing customers to bring their own device!
1. WOW! An Internet service provider that my family has used for quite a while before we moved. Back then, we used an Ethernet connection for two desktop PCs and the service was flawless. Fast forward 5 years and you have WOW! automatically giving customers a wireless router built in to their modem. One thing that I will say before I continue, is that I haven't had service related issues prior to switching to our own router. Not only was our internet traffic being throttled, but their own router actually prevented devices from being able to connect! Plus, probably the worst or most annoying thing about the service was the slow downs when connecting another WiFi device to the router. The most annoying time when this happened was when my Nexus 7 was downloading the latest nightly to Carbon ROM with F2FS (Highly recommended for 2012 Nexus 7 users) at 2.1 Mb/s, then I connected my One X to the router (No Internet traffic on the One X) and the download speed slowed down to about 60 kB/s. That's a speed decrease that anyone will notice, technology savvy or not. So the wireless was disabled by calling WOW! and we plugged in our own wireless router, speed decreases rarely existed but have shown us that their service was part of the problem.
2. TWC or Time Warner Cable, an ISP that probably most of America is familiar with. Their service so far is very reliable, however, when you plugin your our wireless router, your speeds maybe capped at 10 Mbps. No kidding. They give their customers a wireless router built into the modem, and the router completely blows chunks. If you try to connect to the router, it does not give the device internet access. At all! Plus, in order to disable it, you must call TWC for the user name and password. But back on the 10 Mbps cap I've noticed. My mother pays good money for their service, and it should just be provided without any restrictions on what router we use to provide Internet from the modem. But if you plug in a router into the modem that has a built in router, your speeds maybe capped at 10 Mbps. But this wasn't the case when the service was first installed, my first speed test gave the promised 50 Mbps, but has the days continued of using TWC's modem and router and having that plugged into our router, the speeds reached the 10 Mbps came that the modem had in place. But the way how I learned this cap existed was reading the modem's manual and seeing how our router was only receiving 10 Mbps of Internet. Now let's do some math here, 10 Mbps of 50 Mbps is 1/5 of the promised speed. And 1/5 of the $65 my mother pays is $12. But, no, she pays for 50 Mbps, it should be 50 Mbps regardless of what router we use.
Read this before you flash that! (Samsung)
1. So you are looking at your internal storage and you have either a lot or only a few megabytes. So you decide what to backup in TWRP or CWM recovery and you decide to deselect the box marked "EFS" and just backup "system" and "data". With other devices, you can just backup /system and /data, and with others you must backup /boot if you change kernels or Android versions. But backing up that <20 MB partition can actually save you from buying another device. This partition contains very unique information about your device, like carrier unlock code and IMEI. In some instances a lost of /efs can actually cause the power menu to be obsolete.

Basic Phones, Feature Phones, and Smart Phones What to buy?
1. Basic Phones: They are always know for great battery life and phone for making phone calls in those desperate situations. They are available on every major carrier and have basic applications that have capabilities such as basic games (Any Brick Breaking Game) and picture mail. So, if you are shopping for a device for someone who doesn't need anything more than calling or texting that "LOL" to that special someone. These phones are given a great reputation as well for their reliability because of how long they can last when taken care of. Also, with years of ownership, the most you could pay for is probably a new SIM card or battery.
2. Feature Phones: These phones are generally given to people who receive their first phones (Teenagers). The variety of options you have to choose from can throw your mind into a frenzy. You can have phones with full QWERTY keyboard that have full MMS capabilities and some can even use 3G (HSPA or EVDO) networks. They make a great option for those who wonder what type of phone to give someone for their first phone. You may not want to embarrass them with basic phone or don't feel it's right for them to have a full fledged smart phone. They also can have GPS applications and can run some modern games. But, they can have terrible battery capacities, so if you don't charge your phone. bring an additional battery.
3. Smart Phones. These beast are just about made by any major manufacturer and have full email, GPS, gaming, and full applications. The best feature about owning a smart phone isn't about what comes on the phone, it is what can be downloaded on the phone. Users on Apple's iOS platform can choose from thousands of iPhone specific titles alone. Users on Google's Android platform can choose form thousands of applications specific to phone or tablet. But, with all of this power comes great responsibility. Users on Smart Phones can pay much more and carriers often try to deceive customers with buying what they don't need. Also, smart phone battery capacities can vary, so consider purchasing an additional battery.

Custom ROM Don'ts
1. Don't flash a ROM without a proper Nan-Droid backup: So, you just installed a custom recovery and you're looking for new ROMs and mods to install? Great! If you are inexperienced with ROMs, don't flash a new anything but a recovery without a full Nan-Droid backup that will get your phone back to where it can be useful. Wondering about storage? Generally, a stock ROM is going to use the most space on a Nan-Droid backup, so I highly recommend downloading a stable version of CyanogenMod or Paranoid-Android so you can restore, should you stumble upon a brick. But, only install applications and contacts and other things on a need basis on this fail safe backup.
2. Don't flash anything that does not have your device's name on it: If you have the HTC One X, you should know that there are two model names for HTC's previous flagship. Those are Evita (Qualcomm Snapdragon) and Endeavor (nVidia Tegra 3). Only flash things like recoveries, kernels, and ROMs only for your device!
3. Don't flash anything just because it's new and flashy: This is not to offend anyone, but as a reminder that just because you see that KitKat nightly, that does not mean it is safe to approach without protection. Nightly/Weekly ROMs can come with the greatest features and tweaks, but this can also cause huge issues. For example, imagine flashing a KitKat nightly and you notice that the APN section keeps crashing and you know that you need the APN field to get data access. Or your GPS does not work after the latest nightly and you may need it because you are unfamiliar with the area. My point is, what ever that reflects is not a diamond.
4. Don't flash a new ROM without a power source: It is not best at all to flash a new ROM while you are at school, yes the changelog may include some appetizing features. However, what if while flashing this new ROM, your device were to lose 35% of it's battery? These are things to think about while flashing new anything.
5. Don't flash anything over a new update: If you just received any update, check to see if your bootloader or any firmware has changed. For example, when the Evita HTC One X received it's 4.1.1 update, it made the touch screen completely useless on custom ROMs. This made the device useless on custom firmware, so if you didn't make a backup and the RUU didn't come out, you were let in the cold.

600 MHZ auction? Leave AT&T and Verizon
Right now, it seems as if AT&T and Verizon need to use more of their AWS and WRS (AT&T) spectrum before attempting to purchase any new spectrum. AT&T and Verizon have waited a long time to purchase spectrum to reach all of it's customers, but that is besides the point, while markets such as Washington DC still have capacity issues and it's been years since we've seen noticeable improvements from either carrier. These capacity issues have left me personally to switch to T-Mobile, but I'm not saying that anyone is perfect. Even with T-Mobile, I get very fast LTE with the trade off of having high speed data inside of buildings. But nonetheless, 600 MHZ for AT&T and Verizon will not give any benefits for coverage as their existing spectrum already tackled this issue.
Leave your idea's and comments of who should be in the spectrum auction of 2015 for 600 MHZ.

Why you need AWS on T-Mobile
When I originally switched over from AT&T to T-Mobile, I was confident in the 1900 MHZ rollout with the AWS LTE. But, I quickly learned that AT&T is the exact opposite of T-Mobile, AT&T has great coverage with mediocre data performance, however T-Mobile has great data performance with mediocre coverage. This is due to the fact that T-Mobile uses 1900 MHZ and AWS for their network, while AT&T uses 700 MHZ for LTE, 850 MHZ for voice and data, 1900 MHZ for voice and data, and AWS for voice and data in some markets. But, don't confuse this as me bashing either carrier, if you want coverage, go with AT&T, if you want data performance, go with T-Mobile.
But as I said before, you need AWS for HSPA(+) on T-Mobile for data. There is no getting around that, the 1900 MHZ rollout seems stopped in it's tracks and not every AWS/PCS cell has LTE. T-Mobile does have a frightening amount of LTE dead zones in residential parts of the city. Not suburbs, the residential sides. Normally, if you had an AWS handset, you would go down to HSPA(+) (Most likely DC-HSPA+) and not onto the ancient EDGE network. But, if you look at T-Mobile coverage maps, the pinkest areas are LTE/HSPA(+) and the darker pink areas are EDGE. T-Mobile does not show the frequency band of their HSPA(+) network on their coverage maps, and places such as Carmel, NY are excellent examples of non existent LTE coverage (Obviously, if it's nearest major city is 1 hr away), but still, the area is 100% AWS for HSPA(+). So, even if you don't travel, you may want to consider picking up an AWS handset and putting your T-Mobile SIM in it.

Testing T-Mobile Signal, Speedtest, and Roaming
Low Memory Nan-droid Backup
However, this solution does not come with any warranty what so ever, if you brick a device, you pay the price. Now on to my solution, which is to download a "Slim bean" ROM and place it on your SD card and flash the Gapps for your ROM. Then, flash the ROM as you would any other ROM and flash the Gapps and customize your device by putting only the necessary things like your contacts and applications you need everyday. Then, (I should have said you need to be on TWRP) do a Nan-droid backup with just the data checked, (it should be very small as it only contains things you need). Then, delete the Gapps and keep the the ROM on your device and all of this should be under 300 MB. The trick is to only do a backup of /data partition which should only contain the needed applications.
The process of using this solution is quite simply, flash the "Slim Bean" ROM and reboot to the ROM (THIS IS NEEDED TO AVOID BOOTLOOPS) and reboot back into recovery. Then when in recovery, restore the Nan-droid that contains just the /data partition as this is only the needed partition for this to work as you have just flashed /system and then your device should boot up to just the way you had it. This solution will work on any device.
1. Download a ROM. 2. Download Gapps. 3. Flash ROM and Gapps 4. Customize with only needed applications 5. Back up only /data partition 6. Delete Gapps .zip 7. Flash ROM 8. Reboot to recovery. 9. Restore Nan-droid with only /data partition. 10. PROFIT!

Why Applocking software isn't useful
I'm publishing this post to state a few points to say that on Android Applocking software should not be trusted. On Android versions 4.1+ Android features a feature called Safe-Mode that disables all third party applications that are on the device, to include KIK, GTA VC, Hulu Plus, and Applock. Even when the you grant Applock device administration you still can bypass Applock by simply booting into Safe-Mode and deactivating device administration, this is a problem because any Applocking software can be disabled!
Also, owners of devices with unlocked bootloaders can be at risk of all security measures before encryption can be disabled! Simply flashing the appropriate TWRP recovery for your device or by using a recovery or .zip with a file manager is at risk of data being stolen if lost or stolen. If you boot the device into recovery and navigate to data/system and delete locksettings.db and all files called locksettings and delete gesture.key and password.key or .db. Then reboot then you should have an unlocked device!
ALL MODIFICATIONS ARE DONE AT YOUR OWN RISK!
Keep in mind that I'm on an AOSP ROM so your steps may vary!

Why the Nexus 7 is the best 7" tablet.
The Nexus 7 is described as powerful and the best bang for buck. Many users describe the Nexus 7 as being exactly that, a device with a budget price and having lots of SPEED and not to mention always having the latest major Android release.
The Nexus 7 (2012) offers a nVidia Tegra 3 CPU which in 2012 the Tegra 3 chipset was arguably the most talked about chipset but without LTE it was a drawback to Qualcomm S4. I can't give my opinion to the Nexus 7 (2013) as I don't own this model but I do intend on upgrading only for the unlocked LTE, which by the way is making my mouth water and the HSPA+ with S4 Pro the icing on the cake. I do like tablet however, it has very poor NAND chips that frequently need TRIM to run on them to keep the buttery smooth performance. Also, I recommend Paranoid Android with the Franco Kernel for the best performance and battery life combo. While I still like my One XL I do think about getting a LTE Nexus 7 and use that because KIK is being used more often than the stock messaging app. Also, KIT KAT is going to be a tasty update that I believe should be given to the Nexus S as a bed for it to rest.

Why iOS lags behind Android
You know this war still exist but I still feel that after leaving my YouTube channel to collect dust for a while I still feel iOS lags behind Android in a few categories that mean a lot whether that be in speed or security.
When rooting Android your device is safer in malware attacks. With a jaikbrooken iOS device you must worry about your root password but as with ANY UNIX OS you must worry about protecting your root directory but I and many others feel that with tools such as SuperSU and SuperUser Android just does protection much better and without emulation of root rights.
Android thanks to it being open source and having a debugging bridge exploiting the OS of the device is possible much sooner than iOS.
iOS does a piss poor management of RAM leading to random slow downs and high battery usage. Unused RAM is wasted RAM but thanks to Apple launching iOS 6 memory leaks are much more prominent and consistent in times when a phone needs to be just that a phone.
Android thanks to the Different Screen Size API applications coded for a Nexus S can work the same on Galaxy Tab 10.1 .
Things such as native hardware acceleration was adopted with Android in 2011 in ICS (First seen in HoneyComb but wasn't automatically enabled). Apple hasn't incorporated this because in my opinion because when a device slows down they want you to buy a new one.
iOS devices (Newer) when jailbroken still can't overclock or use custom kernels.
Phone calls on my iPhone 4 were excellent but when I started using it more I was reached but the fatal flaw on the Audio IC which still is plaguing iPhones today.
I have nothing against Apple or iOS I just feel that owning an iPhone myself Android has better demonstrated a faster and more fluid UI and much higher consistency.

Nexus 7 LAG FIX
The 2012 Nexus 7 is a little over a year old and many users often complain about massive LAG in the UI and using applications. Before their were only 2 solutions and both of them involved removing data from the device, factory reset, and deleting items when the onboard storage reaches below 3GB. The problem can be fixed by running TRIM which is run automatically in Android 4.3, but if you don't want to update you can try can awesome app that can run TRIM automatically or on demand and that app is called LAGFIX(fstrim).
TRIM wipes block data that the storage no longer uses. Another thing is think about is, can an iOS device run TRIM? Or does Apple not allow TRIM so you can feel like you NEED to upgrade your slow device? Android on the other hand isn't like this. I think that's another piece of information that Android is more advanced than iOS. Period.

T-Mobile 1900MHZ HSPA(+)
T-Mobile has been covering Washington DC with 1900 MHZ since the day it was launched and yes did I get excellent speeds with the compromise of coverage, meaning that due to lack of coverage 1900 MHZ can reach my speeds were lowered to EDGE in buildings and received numerous dropped calls. But, let's look at the history behind 1900 MHZ, the band was originally used by AT&T (still is today) to provide GSM/UMTS to their customers so this band is the reason why AT&T earned it's reputation back then as having the spottiest coverage in the US. So to keep it's customers AT&T did a 850 MHZ refarm, similar to what T-Mobile is doing but T-Mobile is doing this at a slower rate due to not having the money to deploy spectrum in every market. But if you would still like to try out T-Mobile's 1900 MHZ network you can do so for less than 40 dollars and use this as an on demand service or use it for primary uses.
If you would still like to test out T-Mobile's new 1900 MHZ network I'd recommend using a device like the Nexus 4 or a device with 1700/2100 MHZ bands as T-Mobile non 1900 MHZ network is AWS so you need both 1700/2100 MHZ bands to get T-Mobile HSPA when not covered by 1900 MHZ. But if you live in an LTE market, I'm pretty sure the super fast LTE speeds will compensate for the lack of 1900 MHZ coverage.

What iWant for iOS 7/iPhone 5S
Right now iOS 7 is in beta stage and I have tested out a few webapps that I've made and they work flawlessly but that's besides the point. iOS 7 right now all I think about it as just eye candy I like all of the icons but I feel that iOS 7 is missing somethings. I know iOS 7 is in beta....
1. NFC support for the iPhone 5S and maybe a case or dongle to allow NFC support for the previous iPhones.
2. AirDrop for all iPhones and iPads. Apple is notorious for leaving out features in newer iOS versions for only new iOS devices. Can't say the same thing about any Nexus.
3. A debugging bridge to issue out root commands or get a logcat to diagnose the problems.
4. Faster and more fluid transitions on iOS 7. Seriously Apple the transitions take WAY to long and need to be more fluid.
5. At least a quad core CPU if Apple can do it make your own CPU but I want to go with what I know is good but doesn't exist A S4 PRO CPU & PowerVR SGX 544MP GPU. That will murder the benchmarks.
6. Category 4 LTE equipment to boost LTE speeds past 100Mbps.
7. Native Hardware acceleration in the SpringBoard and maybe in applications. (Sorry Devs :( )
