Since the ICS update, I have to use speaker phone on my HTC Thunderbolt in order to be heard by the person on the call. I can hear them, but they can not hear me unless I activate the speaker phone option. I have been to 2 Verizon corporate stores, and emailed HTC with no response. Otherwise the update seems ok, phone is slower than before, and sticky when typing. I can live with that, but I want my phone to work. Verizon stores want me to buy a new phone. I dont want a new phone, I want the one I have to work like it should. Any advice ?
