I have had nothing but issues with my phone after the jelly been release.. Called tech support and they had me do a hard reset.. didn't work and the issues just got worse (wifi, pic messages, random icons moving from screen to screen) today I called again this time she had me do a reboot to safe mode. Everything worked fine.. She said that some of the apps from the previous OS isnt working right with the Jelly bean. In order to fix you have to (trial-by-error) find what app is causing the issue. I deleted a bunch of apps i no longer use and so far the phone is working fine,. Crossing my finger she was right and Ill have no more issues!
