Folks, New to forum but plan to spend spare reading time here now that I've switched to Android. My S3 got lightly wet. Did the rice drying for 48 hours. Everything seems to be functional except my return and menu keys. No lights, no click - nothing. Searched and read all I could find. Did a factory reset, changed settings, still not working. I've seen the youtube videos on how to change out ribbon and keys. Any experience out there as to whether doing so might fix my keys? Or, if they are fried, would it be farther up (after the ribbon an keys)? I could install screen keys but I think everything I've read says I need to Root my phone. I haven't crossed into that territory yet. Any help/experience would be appreciated!
