Samsung tab A7 lite

[Safeer1]

I have been noticing since the last update. A yellow spot had been developed on the top right of the screen  and now the spots are increasing and a yellow line is being developing. Can anyone tell me what the problem is and how can I get it fixed #tabA7lite

Is screen still responsive? Has it been damaged in anyway?

Could try soft reset by pressing and holding power button and volume down button

Any newer updates to install?

If not resolved, then back up information and do a factory reset.

If doesn't fix, then call support and ask for repair where engineer can find out what the issue is.
