To make sure that this is not software related, set it back to factory settings, without using any backup data afterwards. Set up the rest of the personal settings manually and test the phone.
If the phone works, restore from the latest backup. If the problem comes back, the backup data contained corrupt data, causing your issues.
If it still does not work, this is a hardware issue and the phone has to be serviced by Apple or an Authorized Apple Service Provider:
Use iTunes to restore your iOS device to factory settings - Apple Support
