Hangs up after 2:15-3:00 minutes. No warning or anything. Screen has also been flashing, even when I'm not in messenger. I know messenger is the cause of this because the chat bubbles flash, even when the screen is still doesn't. This can be a MAJOR problem for people with epilepsy or people with aura migraines with light triggers. Messenger has no update. I have a Samsung Galaxy J7 Skypro.
