Why does the Coolpad Quattro 4G touch buttons on its own?

Need help with coolpad Quattro 4G did a hard reset cause it would push buttons without me touching them. After reset it still happens! HELP!!!!!s?

Are you using a case? It maybe the reason behind the random key press. Otherwise, you have faulty keys, if that's the reason, I suggest that you bring it to the store where you bought it and have it repaired or replaced.

Not the answer you were looking for?
