I am having the same issue with my cellular antenna. No one can ever hear me for very long. Calls always drop. even with excellent reception. I have recoreded memos and the microphone on the device works fine. I always have to text instead. which is usually ok. but sometimes I really need to call a business and speak verbally with the representative. I am a backer. I have been waiting and hoping for an update. Since FX tec stated they fix whatever reasons preventeted updates on the Pro 1. However I have yet to see an update for the Pro1 X. Some help please.
