Anytime I try to make a call with my phone, zte n817, it drops the call before it can be put thru. The Mute button is dark, which means it is in use. I can’t get the button to light up. I need some help here, I cannot make a phone call and that’s what I have the phone for. I have taken the battery out, done everything I could possibly imagine that might help the phone, but nothing happened. So I sit without a phone to call on. Thank you Martie Martin….please get back to me somehow…
