Symptoms started last week, haven't done much different on the phone. Uploaded a video to YouTube but that was about it. When I click on the YouTube app from either the app menu or it's saved location on the desktop it flashed black for a second, I see YouTube up in the title bar of the screen (top left where the app name would be) and it goes right back to the screen I was at previously. I have tried clearing the cache and saved data of the program, made sure it was not running and force quit it if it was (but it wasn't), rebooted the phone, powered it up and down, tried airplane mode on and off, but nothing works. have uninstalled any apps I have installed recently but the same thing keeps happening. YouTube works fine when viewed via a web browser but the app itself wont open. Any suggestions?
