Manually remove app settings
The twitter application I was using stopped working and was constantly crashing my phone. I deleted the app, yet the settings and options that link in with other apps still remain (instagram etc). Whenever I click on these my phone crashes. Is there a way to totally remove all traces of this? I have tried backing up restoring, updating and a hard reboot yet nothing has worked. It's driving me up the wall. Any ideas?
