I have a one year old W580. Today at school, the left soft key, including the back key was working fine. Then after school, I tried unlocking my phone and it didn't work. Turns out the left soft key, including the back key, stopped responding. What can I do to fix it?
I tried removing the batter and putting it back in, and the keys still don't work. I also turned it on and off a couple of times. I only dropped my phone like 4 times within the phone's lifetime, so I'm sure that can't be the problem. I didn't drop it today either.
