Well you can try a newer build, but the capacitive buttons at the bottom (start call, end call, home & back) are notorious for being flaky in Android.

I'm not sure what the issue is, some have said that cleaning this section of the phone helps. It's very random for me tho - sometimes they work perfectly, sometimes I hit home and it hits start call instead, same with back being mistaken for the end call key.
