The SM-G850FQ variant of the Samsung Galaxy Alpha smartphone might not be as popular as some of the others, but it can still run all the same root apps once you unchain the system internals using the guide below. Once you have that mastered, you can instantly install many of the same apps you always hear about like Titanium Backup, Greenify, ROM Toolbox, ROM Manager and the Xposed Framework just to name a few.
While those apps deserve to be at the forefront of many people’s root application lists, there is one thing none of those names do: improve the performance of your device by overclocking. It’s normally not a cheap thing to do when you think about going to install something like the SetCPU application. Either that or go to the effort of installing a custom kernel and a custom recovery. There’s one application that can help you change the way your CPU performs and it does it all for free. That way is by using the CPU Tuner application.
The CPU Tuner app can tweak the way your CPU is set to increase battery life or increase the performance. When you increase the performance you are agreeing to take away from the battery life and vise versa. It pays to take care and research what your hardware can handle before you install the CPU Tuner app on the Samsung Galaxy Alpha smartphone so you do not break it, but it’s a great app for those who are advanced Android users.
