just received my mi3 through fedex.

Everything is fine except one major issue where as soon as I dial a number the whole phone phone fades and becomes unresponsive regardless of the button i press.

There is no thing i can do to get it working again. It would last until the call stops which means nobody answers or the receiver hangs up. This also means I have no option to hang up the call as the entire phone turns unresponsive

Anyone experiencing the same thing? this is hella annoying.
