I was using resurrection remix rom. quite a stable rom but suddenly my phone started to lag alot.
I thought of switching back to stock rom rooted and check if the same problem persists.
Yes it did. And now I've no idea what to do. Someone please help on how to get rid of the red box in the download mode and lag reduction.
P.S: I'm not criticizing Resurrction Remix ROM
I'm using a fake samsung battery. Does that affect?
