I REALLY do not want to reset the phone to factory setting...I was unable to get to the safe mode during the reboot sequence.  I held down the on/off butten untill the the Google logo showed, then released that and held down the volume down button....it didn't work, I kept getting the buzz letting me the volume is off and the flashing colorfull reboot images....it kept repeating the buzz the images the buzz the images....So I poped the battery out repeated the sequence and ignored it while reading about the safe mode, etc.....it went back to the Google logo and stayed there.
