Update overheats SIM card

manyburgers

any answers on the overheating and other issues caused by the update to galaxy threes? My S3 used to be good but after the update it overheats (not the battery) and cannot lock onto coverage, among other problems. The store blows me off and claims it is the battery

Is this to KIt Kat I presume, It's been an OS with big issues for some possibly all phones in one way or another, the only few suggestions that might possibly help is to Run a System Cache it can as kind of works as a clean for your phone or you may have to run a Factory Reset if haven't already.  I would say until and update come out to fix the one your phone updated to there not to much you can do..

I had to replace a phone back in Feb. because of K.K. my replacement still has Jelly Bean on it..  Hope this Helps b33
