Custom ROM Cyanogenmod
CyanogenMod Roms are custom ROMs which can be installed on your Android devices after enabling root level access although if your device is under warranty then it is not recommended to install ROM because after enabling root access, the warranty of your device from your device manufacturer or warranty provider would be voided.
It’s free, and it extends the capabilities of your device with themes, dramatically improved privacy functionality, and all sorts of UI/UX tweaks. If you have a rooted device, installing CyanogenMod is incredibly easy. The CM team created an app called CyanogenMod Installer that lets you download and flash the ROM with minimal technical knowledge.
We would recommend to backup any data and contacts as the process would format your complete phone and its OS as well.
