Sorry if this has been posted already but I'm having issues ending phone calls on my zte warp. When I try to end a phone call the dial screen wont close properly, I can press the end key and it lights up but there is no response. I'm able to press the home key and get out of the call screen but its still bugged out. I've tried shutting my phone off and on a few times but the problem keeps recurring. I'm going to call customer service but I've been on the phone with them twice today, Any help would be really appreciated!
