It's on 4.1.2. Previously I did the hack to keep the old bootloader and update to Jellybean but not sure I want to go that route again.
I was getting some crazy slow downs, where the phone would lag for like 4 seconds when trying to talk into google now, or it would take a few seconds just for the keyboard to come up, and then the swipe action would show up after I I had finished swiping. I'd say it was more common to have this lag than to not have the lag.
Also, I missed the navigation app because maps was super slow and took forever to use. Should I just stay on 4.1.2 or take the update? Were the slowdowns because of the rom I was using or because I decided not to update properly?
edit: I also noticed scratches on my replacement near the power plug, but I guess that's part of getting an insurance replacement... Planning to upgrade soon but waiting for the new phones coming out later this month first.
