White screen with green stripe at top flashes on my screen

[Bob33Builder]

Trying to figure out what and why I get a very quick flash on the screen of my S7 Edge.

I will be doing something, texting, reading news, whatever and my screen very quickly turns white with a green bar across the top, then reverts back to what I'm doing. It happens so fast that the only thing I can see is what I mentioned here.

I will restart the phone, go back to what I was doing and it will happen again after maybe 30 seconds or so. It is random, doesn't happen all the time, but will just suddenly do it. When I reboot it usually will repeat as many times as I restart the phone, unless I restart, then don't use it.

It's been doing it for many months and drives me nuts! I need to know what is causing it, what it is. I am suspecting maybe I've been hacked, something tracking me, who knows?

I have no idea how to find out what this is, so I'm turning to you folks in hopes someone can help me.

Phone is not modded in any way, Canadian in Alberta with Telus. I bought the phone outright with no contract.

Thank you

In addition to the standard ones they load with the phone, I counted about 42

Not bad , around how many I usually have . Either try 3 at a time or factory reset and put 2 at a time until problem resurface

Factory reset... yeah thought of that. Such a hassle to reload everything though. If I restore from backup I will likely restore the problem too.
Is it possible to disable the apps individually? I find that some settings I change go back to default every time I restart.
This evening my battery was being sucked down hard, was 17% at dinner time, then a while later 10 then 9 8 7 - 2% when I plugged it in.
Pulled up battery usage and Android System had 20% of it. Coincidentally the same color green used for that as the offending screen in question.

BTW, thank you.

I think factory reset is better option and no restore start from scratch and load the app little at a time

It'll take some work, gotta make sure all my stuff is backed up properly. Several thousand pics... ugh. Guess I should delete crud after a while. Never seem to have time.
Thanks for the advice.
