Well today I can make a phone call with my A7 but after 10 to 15 seconds the person on the other end can no longer hear me. I have had so many problems with this phone I am finally done with it. I have rebooted until I am blue in the face. Same issue every time. After 10 to 15 seconds the other person can no longer hear me. I am trying to make an important phone call and can not. I have had it with the A7. Those of you that still have yours I wish you luck. I am not even going to try and get it exchanged or fixed. I am finished with ZTE. Buying an HTC U11 right now. I should have stayed with HTC but I thought I would try the A7. This has been a nightmare. Avoid and run from ZTE if you can! To my friends I have met in this forum I wish you luck.
