From the very 1st day, I have noticed this bug. While using Twitter app, sometimes screen of M31 is getting black and blinking. Right now it's only happening for Twitter app. #samsungM31 #Screen #Blackout #Blinking #Twitter #Fixbug
I don't think it's a problem related to motherboard, it's happening occasionally. It's a problem related to software update, I read about it in some newspaper articles. You may search it on Google.
actually I don't know, that's why I raised the question in this samsung community. For me also, it's brand new samsung M31. You may follow the thread, there is a solution suggest by CS-member13, try it.
