You posted this in the Att section after KK update. At first, I was a non believer. But I was having all sorts of problems. Index was running all the time. Couple of lockups just random things that annoyed me. I hated to do it, but I finally factory reset and works better than ever. At work I use a Verizon N3. I'm having some of the same issues post update. About to factory reset this one too. It solved all of my issues on Att N3. By the time Google, Samsung, Carriers throw their code all over the updates, I guess they just don't come out very reliable anymore. The process sucks but in the end it's worth it.
