I would strongly urge you to make all necessary backups and flash a clean copy of the OS and Firmware using Lumia Software Recovery Tool found here: How can I recover/reset/restore my phone software? - Microsoft - USA

This will rule out any software issue. Test it without restoring the backup and if all is smooth then you can do a Factory Reset and restore your backups. (Settings > about > reset your phone) If everything stays smooth great!!! If something then gets glitchy after the backup is restored you need ot look at your most recently installed Apps for the troublemaker.

If the issue is still present after the flash and before the backup restore, then you have a hardware issue and should seek a warranty repair.
