Solved! My back button on Wolder Wiam #51 isn't working properly, what do I do?

My back button sometimes only click on the middle of the screen when I try to use it... I don't know what to do or what's the problem with it.. what do I do? I've already tried to reset the phone but it didn't do anything.

Try restarting (turning off and back on) the phone. If that doesn't resolve it, and the phone is under warranty, contact the manufacturer. If it isn't, then I would try a local tech.
