Top 5 Benefits Of Rooting Your Android Phone
Let’s check out some of the benefits of rooting your Android phone.
Full Control Over Android
You have access to alter any system files, use themes, change boot images, delete annoying stock apps, such as Sprint's NFL Mobile live and Nascar Sprint Cup Mobile, and other various native applications that might drive you crazy (Footprints, Voice Dialer, etc).
Back Up And Restore The Whole System
On most rooted Android devices, you can back up your entire system to an SD card, much in the same way you can image a hard drive. This is great if you’d like to try a new ROM, as you can back up your phone, wipe it completely, flash the new ROM, and if you don’t like it, just restore from your backup to get your device back to exactly how it was before you wiped it.
The easiest way to do this at the moment is by using ROM Manager, developed by famed Android developer Koush.
ROM Manager allows you to easily flash a custom recovery image which is what you will need in order to backup and restore your phone. The recovery image is a special program that can be booted into outside of the phone's main operating system, sort of like an OS recovery console on a PC. By default, the recovery image on most Android phones only gives you a few options, mainly related to wiping the phone. Custom recovery images expand upon these options and usually include scripts that can do things like backup and restore your system, fix file permissions, or allow you to flash custom ROMs that the normal recovery image would otherwise reject.
Normally, flashing a custom recovery image requires some command line work, either on your PC, or on a terminal emulator directly on the phone, but Koush's ROM Manager should automatically flash his custom recovery image (known as ClockworkMod Recovery) for you, provided you're on one of the supported phones (<-- the list in this link should be always up-to-date, as it's maintained by Koush) and that it is already rooted.
Using ROM Manager is pretty simple. Download and install the application from the market, fire it up, and you’ll be prompted to allow the application superuser permissions - make sure you approve it.
The first thing you’ll need to do is flash the ClockworkMod recovery image that I mentioned earlier, which can be done right in the app (it’s the first option). ROM Manager should automatically find the latest version of the right image for your phone, download, and install it - the whole process is seamless.
After that is done, you can simply use the ‘Manage and Restore Backups’, and ‘Backup current ROM’ options to, well, backup your current ROM or restore from an existing backup. It’s that simple!
Save Space On Your Phone
While Google did introduce Apps2SD (moving parts of applications to external storage) officially in the Froyo update, it remains up to developers to manually add support for it in their apps. Because of that, it's still fairly easy to overflow your internal storage and run out of space.
The easiest way to alleviate this problem and enable most applications to be movable to SD would be to flash a custom ROM that enables just that. For example, CyanogenMod, the most popular Android custom ROM, allows the user to force most apps to SD even if developers of those apps didn't enable this feature. See 13 Ways CyanogenMod 7 Makes My Android Phone Feel Future-Proof [Deep Review] for more info on this and other amazing features of CyanogenMod.
Note that this doesn't work on all apps, notably keyboards and apps with widgets.
Run Special Applications
Install Custom ROMs
The Android custom ROM scene started growing shortly after the first Android phone, the T-Mobile G1, was released. The ROMs that were initially available just offered a few tweaks here and there - access to developer only sections of the operating system, debugging information, and things of that nature.
Now, a few years after the release of the G1, the Android ROM community has grown immensely, and ROMs have been developed for most of the Android phones currently on the market.
They've gone far beyond simple tweaks and can now give your phone an entirely new look and feel. There are ROMs that can make your phone fly by replacing the kernel with hyper-optimized versions or even overclocking the CPU. The possibilities are nearly limitless and attempting to cover all of the features of all the ROM's available for all of the phones out there would be pretty much impossible.
If you're interested in flashing a custom ROM on your phone, your best bet is to hit the Googles, search for "phonename custom ROM," and see what comes up. You'll likely find at least one forum dedicated to hacking your phone with plenty of information to get you started.
Here at AndroidPolice, we're planning a series of custom ROM reviews for as many phones as we can get our hands on. Stay tuned for updates!
There is plenty of information on the web on how to accomplish this, but our favorite way is by using Titanium Backup and freezing/deleting the apps from there (root required, of course).
yeah a lot of powerful apps need root, wonder why phones are not rooted straight out of the box
nice article! :)
