My husbands ATT branded Bold has a problem with the sound. When every he syncs his phone to his PC, the ringer and text sound disappears. His settings still shows Normal, yet he can not hear the ringer. If he removes the battery of the phone, all is well; but it seems stupid that he has to take the battery out after every sync.
His Bold is running OS 4.6.0.167 (platform 4.0.0.217). I hope this is enough information for someone to help here.
