    Tethering is one of those things that many of us got really excited about way back in the early days of cell phones. Here we had a little phone that we could connect to our laptop which would let us access the Internet or closed network (the office, university, etc.) without having to plug into a land-line to do so. Speeds weren't all that great, but being able to work from anywhere often trumped that. Today we have our choice of various high-speed technologies offered by any one of a handful of cellular carriers. We also have numerous ways to connect our laptops to our phones -- and we ...

    Over the last little while we've heard that various devices (typically tablets) may be released that have the ability to dual-boot into your choice of operating systems. Some may know what dual-booting is, and others may not. The majority are probably scratching their heads and asking, what is dual-booting, and what are the pros and cons. What is dual-booting? Let's start with something basics. What is "booting" when it comes to smartphones, tablets, and even computers? The basic explanation is "turning on" or "starting up".  In more detail, "booting" is loading a set of instructions ...

    The original Nexus 7 was quite a piece of work when it was originally released back in 2012. Pocketnow's own Brandon Miniman even rated the device an 8.7 out of 10 in his review. Not bad for a tablet that cost less than US$200. What starts to happen almost immediately after we get our fancy new devices? They start to slow down. At least that's what it feels like, right?  Usually this perception is caused by installing a whole bunch of apps that take up more space in the system's RAM, apps getting bigger and slower, and updates to the operating system taking up more space. All of these are ...

    Power users will likely recognize the name +Chainfire as one of the developers who brought superuser to Android and helped make rooting achievable for countless others. As you might expect, he's still very much into the "guts" of Android, and recently came across something a little troubling. When some power users pointed out a recent commit to the AOSP master tree, Chainfire found a significant amount of Android root changes -- which could break the majority of today's root apps. The change AOSP is the "core" Android code that developers use to create ROMs for their devices. Rooting is ...

    When I first got my original Nexus 7, I loved it. Over time, however, it got slower and slower. As it turns out, I wasn't alone. These tablets that started out snappy got gradually slower over time, until they were almost painful to use. Then Android 4.3 came along, and much of that slowness went away. Why? Google sneaked in a feature that's slowly helping restore my sanity: Android TRIM support. Let's get some terminology and technology out of the way. When you think about how computers store files, you probably picture a hard drive (HDD), a rotating set of platters that stores data ...

    Google's Nexus 4 is essentially an LG Optimus G, which has LTE support -- so why don't we? In short, Google disabled it. But we're Android Power Users, aren't we? Yes, we are! Here's how to get LTE on your Nexus 4. First up, some disclaimers. This information has been around for a little while and some of you may say that it's "old news". That's partially true. Although the radio in the Nexus 4 has support for LTE, it doesn't have the certification and some hardware optimizations that are needed to implement it fully. Originally, you could simply make a few changes and get LTE to work for ...

    A while back, we at Pocketnow faced a challenge: our Android articles were taking more time to write and our videos were getting long. The reason for both  was due to the fact that we try and write our articles and script our videos so they apply and are readily understandable by the majority of our audience. We have a very diverse audience -- which is wonderful! Unfortunately, explaining all the nitty gritty details was sometimes overwhelming to various segments of our audience. They'd get lost in the details and miss out on the cool stuff. Another segment of our audience, Android Power ...

    After you've used your smartphone or tablet for a good, long time, eventually you're going to want to get a new one. What are you going to to with your old one? Will you put it in a drawer and let it collect dust? Or will you give it to a friend or family member, or maybe even sell it? Whatever you end up doing, it would be wise to run it through a "factory reset" before letting it leave your hands! In this video we'll go through the steps necessary to wipe four different devices, the T-Mobile G2, Samsung Galaxy Nexus, Droid RAZR HD, and Nexus 7. We'll show you how it's all done on devices ...

    We've talked about how to flash an image using ROM Manager, but if you're more comfortable with a keyboard and mouse, fastboot might be easier for you to use. You'll need to be aware of some limitations and details before you dig in. Hit play, and let's find out just what it take to flash an image using fastboot. Fastboot vs. ROM Manager Fastboot doesn't flash ROMs the same way as ROM Manager. Rather than flashing pre-packaged ROMs, flashboot lets you target the partition that you want to flash: data, recovery, system, etc. Image.img vs. Update.zip When using fastboot, sometimes ROMs come ...

    Everything we've been learning in the Android Power User series thus far has been setting the stage and getting us ready to flash whatever Custom ROM we want on our devices. We've learned about unlocking and rooting, we've learned about Recovery ROMs and system images, now we're going to take a look at an app called ROM Manager that makes use of a rooted environment and Clockwork Mod Recovery to make flashing Custom ROMs very quick, super easy, and something that you can literally do every day. Every day? Why would anyone do that? I run CyanogenMod Nightlies which are, as their name ...

    Android is made up of a small collection of "images", each with its own specific job. Last time we talked about the Recovery Image, today we're going to dig into the System Image -- the funnest one of all! What is the System Image? In desktop and laptop computers, the System Image is basically the operating system (Windows, Mac, Linux, Unix, etc.) that you spend all your time in. You turn on your computer, wait while it boots, then run all your apps and do all your work on the desktop which lives inside the System Image. On Android it's not that dissimilar. When Android boots up it takes ...

    ClockworkMod Recovery, generally shortened to "CWM", is one of the most popular custom recoveries for Android-powered smartphones and tablets. Originally developed by Koushik Dutta, or "Koush", CWM lets power users do all kinds of really powerful tasks that aren't included in the stock recovery on most devices. What are Images? No, we're not talking about pretty pictures that are worth a thousand words, in this context an "image" is essentially a self-contained operating system. Most of us are familiar with the "System" image, it's the part of Android that we use every day. There is also ...

    ODEX and DEODEX are terms that are thrown around a lot when we're talking about Custom ROMs. Some ROMs are DEODEXED, others are not. What does that mean and why do we have them? If you haven't already watched the last couple episodes of Android Power User, you might want to. In those episodes we talk about the JIT Compiler, and the Dalvik Cache and Dalvik VM. If you've already watched those or have a solid understanding of them, let's dive right in! Android apps are stored in .APK files (that stands for "Android Package", in case you were wondering). Like we talked about, the files ...

    In today's episode of Android Power User we're going to learn about the Dalvik VM and Dalvik Cache, why they're named the way they are, what they do, and how they do it. "Dalvik", it's a word that gets thrown around when you're talking about custom ROMs, particularly when flashing a new ROM and the need to "Wipe the Cache". Today you'll find out what that means (just in case you didn't already know). In our last episode we talked about JIT, or "Just In Time", which is the compiler built into newer versions of Android. We sort of put the cart before the horse with that one, but it helped ...

    JIT is one of those newfangled acronyms that are used in business today. It builds on the concept that having inventory on-hand is expensive, and in an effort to cut costs, inventory can be reduced to only that which you need "right now". The theory follows that you order only the supplies that you need for your current production run so they're delivered "just in time" -- JIT. In computing, it's not that different. Just-in-time compilation (JIT) -- sometimes called "dynamic translation", is one way to improve the performance of apps at runtime -- but how it does so is a little confusing. ...
