Hi, i have a Samsung Galaxy S4 (gt-i9595), with the latest update (4.4.2) Im not able to turn on the wifi, i have had the issue for som time, i used to have the issue on he previous os aswell, and updating didnt help. everything else works, bt, gps etc. Its just the Wifi, if i pull down the screen and hit the wifi button, it turns faded green for a few seconds, before if turns grey. If i touch and keep the wifi button touched i go into the wifi setup, here i try to move the wifi bar to the right, but it snaps right back to the off position. i tried wiping the cache partition in recovery mode, and i tried a hard reset. but no wifi What can i do?
