I have noticed that the touch back and search buttons on my phone do not always respond. They respond the most when I have the phone slid open; when it is closed in the portrait orientation they are hit and miss. In certain apps like the music player they almost always work, but other times I have to press several times to get them to respond. I got a screen cover for my phone and now they work even less. My screen touch is perfectly responsive just the capacitive back and search buttons are having issues. LG recommended seeing if verizon has an update for the phone at the store. Anyone else have this or a similar problem? I tried removing battery and restarting already. Thanks for any help.
