Today I was watching YouTube on my LG X Power phone and when I clicked on a video, the screen froze then 20 seconds later, the screen went blank (it's emitting light but no picture) and a few seconds later it went dark. At the time it was around 70% charged I put the charger in, but it's still not turning on, even after an hour. The phone was working fine before, the only weird thing was Instagram stories froze the screen (but only the one from the instagram official account.) I'm not sure what to do or whats going on so please help.
