I am pretty new here, don't know if this is placed in wrong area. I updated my LG G2 to KitKat recently, but have been getting horrible performance, from the battery and everything else. I was wondering if there were any fixes? If not, can someone bring me through a step by step on how to revert to jelly bean? I am not worried about data loss, everything is backed up. No riot or custom revocery either. Running 4.4.2 Stock. Thanks.
