mobile

Over the past couple of months, my phone has become increasingly irritating. It's performance is unreasonably laggy, and the screen flickers on and off continuously once the battery hits a certain percentage (let's say, 50%), which consequently will drain my battery even faster. It lasts for about ~9 hours now.

I can't connect via USB to my computer because it doesn't recognize it, so I can't backup and reformat. I'm running 4.2.2 on AOKP, rooted and everything. I just want to know if anything can be done to fix it as I prepare to purchase a new phone. It's a shame, really, I loved the Nexus when I first got it, but the drop in performance has just been getting me bitter.
