Hi all,

My Tab S2 has started flickering random colours. Half screen is blue other half green then all blue, then all green then all red. Hald red, half blue sometimes half white and half chequered black and white squares. It’s slowly flicking each sequence probably every second. I can hear the screen shot function work when I press the home and power button but that’s all I can get. Any ideas what this could be? Thank you.

No I don’t think so. After pressing the various power and volume buttons I got a bit of info up in the top left corner which went of quickly. Can’t get past the various colour combos
