The screen on my Connect intermittently blacks out, mostly while making, receiving or during calls. If I need to put it on speaker or need to access the screen during a call, the screen won't turn on, it's like it just shuts down and I have to pull out the battery to reboot it because I can't even power the phone off. It becomes completely unresponsive. I have scoured the internet looking for others with this problem but can't seem to find a solution. Has anyone else experienced this or does anyone know how to fix this problem??? Thanks!
