MD4-5 M19 version, having issues with the touch panel. Noticed that the problem is more pronounced when using smaller buttons on screen. By using larger touch buttons the issue seems to be improved but not perfect. The screen responds to the press (it goes orange) but does not actually process the command to exit the screen. Seems very temperamental. Is there a built in delay to prevent button bounce that could be causing this phenomenon? We also tried without the screen protector and had similar issues. I tried without filming and was pressing the screen very firmly and around 6 times before it would register the button press (sometimes it went orange and did nothing, other times it did not even change colour).
