Answer to: Why is my samsung galaxy 12.2 inch keep blinking?Download an app called. Cleaner or any app that has the ability to tell you if it is hot or not. If your tab is running hot, it will blink. why because I am dealing with that issue right now and I will record it and get it fix right away. After 56C to 76C it will start blinking like that.
