My LG G Flex is from AT&T. I did not try recording videos or voices right away, but after all the apps and settings completed, I've found that I can't record video. The top panel with the 4 functions disappear when I click on the red button. There's also no voice recording in any messenger-typed apps, voice memo, or voice command. Please help if there's anything I've disabled or I need a factory reset. Thanks.
