Possible malware attempting to screenshot my phone?

Hi, recently I've been watching a lot of videos on my phone, mostly on Amazon Prime Video and Netflix. Every once in a while, the screen will react as though I've tapped the screen (triggering the play/pause UI). I thought this might be caused by a new wireless charger I purchased recently fluctuating, but today when watching Netflix I got a prompt saying "Unable to take screenshot due to security settings." even though I didn't attempt to take a screenshot. Has anyone encountered this before? Is it possible there's malware on my phone taking screenshots and doing something malicious with them? Any help is appreciated!

Try a Cache Partition wipe. Tell us if that doesn't fix it.

Welcome to Android Central! Which phone? If it's a Samsung, perhaps a phantom touch is being generated that makes the phone think you're trying to do a palm-swipe screen capture. Phantom touches might be generated by a problematic wireless charger, or also a poorly fitting screen protector.
