They started to be unresponsive just every once in a while a couple weeks ago I would have to restart the phone and it would work again. After a week of that I had to reboot it repeatedly until I was lucky enough to have full control over my phone. I used Kies to backup my phone and then I updated to the most recent firmware on 11/10/2012. Kies and My S2 alerted me the firmware updated successfully.
For almost a full day my S2 worked better than ever then the buttons stopped working completely. It's been two days with the buttons being completely unresponsive. I tried dialing #9900# to do a system dump but that was "unable to process". It also won't connect to Kies now. I never tried to update it with firmware that wasn't recommended by Samsung Kies.
If I try doing the #9900# to wipe system memory I get a "USSD Code Running..." then an alert pops up saying "Unable to Process Request" same thing happesn with the #1234# check firmware version.I also have a "Wi- Error: ER05 "invalid SIM card" error.
Any help would be great. I really don't want to pay $180 insurance claim for a new S2 when they have so malfunctions so frequently. My fiance and I both have the Galaxy S2 and they have both been glitchy since we bought them and continue to get worse. We've put a lot of money into these phones I think T•Mobile and Samsung should at least trade us the glitchy S2 model for the S3.
Thanks for reading hope to find a solution soon (not a $500x2 solution),Aaron
Thank you for the tips, unfortunately I didn't have success fixing the issue. The first time I did the system restore the menu button lights lit up just for a second but they never worked. I tried most of the solutions more than once actually. I just can't imagine it being a hardware issue because it seems it's just not telling the buttons to turn on because everyonce in a while like one day every few weeks the buttons all work like nothing's wrong.
I've found other S2 owners with the same issue on multiple threads and it seems no one has solved the problem.
here's another guy with the same issue that I was just looking at.. nothing helpful but proof of the same problem.http://samsunggalaxysforums.com/showthread.php/9686-Four-Bottom-buttons-only-work-sometimes.
Have you tried a factory reset? It sounds like it might be a software issue (maybe an app). Try a Factory Reset and don't restore your apps right away. If it works fine, restore your apps one by one with some time in between to see if the issue comes back.
