Hi. I was using my Samsung galaxy s7 today while i was surfing through facebook suddenly half of my screen was stuck. and when i moved back to homescreen it remained there. I restarted and then half of my phone was static with white dots. the other half is working and touch is also working on both sides. I have attached a video with it too. https://www.youtube.com/watch?v=F3zcn2nPdF8. Help will be highly appreciated. Thank You.
