I think that it is a minor issue.
Workaround is go to Settings -> Battery and disable Ambient Display there.

Well, i do not have this issue.
Which gapps did you flash? Personally i flashed unofficial pico 8.1 arm gapps.
Did you tried to make a hard reboot using hardware buttons?

the tablet did work for an hour, like youtube and steam and stuff, i used this file open_gapps-arm-8.1-stock-20171216-UNOFFICIAL, and hardware buttons dont work
ill have to wait for battery to be down then boot in recovery, but then?

Well, actually you must hold Vol-, center and power hardware button. When you see a samsung logo, hold Vol+ and center button to enter TWRP. Wipe data and cache.

Dammed. I can not reproduce this issue.
When i tried to boot LOS 15.1 in december, it stuck in bootloop many times. But i always was able to reboot to recovery or fastboot.
So do not worry and just calm down. Yeah. It is impossible to turn off device when it is bootloop.
But you always can reboot in recovery or fastboot using buttons combinations which i told you

There is a way to fix bootloop. Although its works only half of the time?

So what i do, is reboot back into recovery and choose the option at the bottem left, dont know what its called, and then choose "fix context" or something like that.
And that should work (sometimes).

Install it after hours of errors on twrp. Installed opengapps Google play store was not loading I reinstall it 3 times and nothing. I was not able to install apk files too! This ROM at this time suck big time! I download 14.1 from this forum and its working perfectly.

I am disagree with you. I can not reproduce your issues,
ROM installed fine without any errors.
On my tablet Google play store works fine.
Also apk files install is fine too.
