Why do people want to root their android smartphones?One of the main reasons why people flash custom ROMs is to enjoy a totally different look on their Android device, but there are also other people who flash custom ROMs because they want improved performance and longer battery life. Then, there are the individuals who want to taste the latest software update even before the official release reaches their phone.
A lot of the time, developers give users who want aesthetics, performance, and being up to date all of these things in one neat package. Of course, developers also throw in their own touches, such as home-brewed kernels, tweaks, and optimizations and cut away unnecessary apps that take up precious space.
The ROMOW EXTREME ROM, developed by XDA Developers member mowow, gives users the much-craved-for Android 4.1.1 Jelly Bean taste with a side order of being deodexed and zipaligned. The ROM also has a number of goodies thrown into the mix, such as BusyBox, Superuser, and optimizations for improved battery life and performance. You can also enjoy an enhanced Task Manager, an extended Power menu, and a whole lot more. The ROM’s size is also small, so you can easily enjoy the Samsung bloatware-free experience without any lag.
