As the title says my phone will not vibrate at all. No haptic feedback when entering phone numbers, none for texting, and none for notifications or calls. I've tried everything I can think of. I've tried going back to the original 2.1 update vs the OTA update. I've tried a soft reset, and also going into the phone menu to do a factory reset. I've even tried the sound manager app trick and still no luck Any ideas on what might be the problem?
