4S becomes unresponsive after Genius Bar restore.
A member of the Genius Bar restored my iPhone 4S because of some 'minor' errors such as crashing apps taking up space. She done it yesterday and now it has become more unresponsive than ever.
Whenever I'm in a call I can't unlock it or use it whilst in a call (FaceTime, FaceTime audio, skype, Facebook call) I have to hard reset the phone which is kind if annoying!
She also said these words "it'll speed up your iPhone making it as fast as it's supposed to be". Its not fast. Not fast at all, infact I can tell that it's more slower and laggier .-.
Can someone please give me some insight on how to fix this?
iPhone 4S, iOS 7.0.4
