After I got the update to 2.3.6 the touch sensetive buttons at the bottom of the screen quit lighting up. I have the settimg set to always on but it doesn't seem to matter what setting I have it on they don't work. I found that at the lock screen if I hit the power button twice fast they will come on and work. That IS the only way I can get them to come on. is anyone else having this problem? I would guess it is software and not hardware related. I'm also having lots of problems with GPS it takes 15-20 minutes to find my location standing outside with a clear view of the sky with almost zero clouds in the sky.
