Recently, whenever my phone has the vibration setting on and I receive a phone call, either in ringer or silent mode, my phone will not stop vibrating during the call and after the call has concluded. I've had that problem before and had it fixed at a Sprint store. Another hardware issue that forced me to exchange the phone for a new one. The new phone now has the same vibrating issue. Has anyone had this problem and was able to fix it without bringing it in?
