Grey horizontal lines across screen

[HamptonCaught]

Sorry if this has already been posted anywhere, but I couldn't see anything. My Samsung S7 Edge upgraded a couple of weeks ago to Android 7.0.

Since then, I have three dark grey horizontal lines across the screen (each about 3mm deep), which are there whatever I'm viewing or have open.

If I screengrab, the lines do not show.

I've tried rebooting and starting up in safe mode, but nothing has made any difference so far.

Has anyone else experienced this?

The phone has not been dropped, mishandled or become wet at any stage.

Thank you for any help!

Thanks for your reply.

I bought the phone off someone who had won it in a competition, so it was brand new, but I guess won't be covered by a warranty.

I'll have to try and find someone who might be able to do the work and get a quote. The lines bug me everytime I look at them!

Estimate replacement S7 Edge AMOLED screen and digitizer about $200-300.

One day after posting this, the lines suddenly disappear! I'm guessing they'll be back, but all is good - for now. I guess it's going to be an issue that comes and goes until it's fixed permanently.
