Remove update

[LISSCH84]

This update was utterly ridiculous. Since it was updated, my text message alerts won't clear, my battery drains very quickly, I randomly lose wifi, which has made me use almost all of my data because I didn't notice, apps randomly shut down, and I got to this page trying to open a menu I downloaded. Is there a way to revert to the old version without losing everything on my phone? Also, my Bluetooth connection randomly goes.

You can't revert to the previous version of the OS. You can try a system cache clear through the recovery menu to clear out any old bits of code and to force the phone to optimize the applications again.

I did a cache clear from recovery and it did not help at all
