I guess that Samsung did an software update so other peeps and myself are having the same issues? Or maybe Mongo is trying to wreck Android phones like he has done to road racing and has hacked them and blew up their system?
Zen4 needs to push out an update, likely. Been seeing similar issues for awhile (on an older S7). Happens on the home page and messaging screens, primarily. If you get into the General, Tech, etc. sections, the display looks fine. The above-mentioned checkbox-fix works, but is more of a band aid fix - and lends itself to CSS likely being the culprit on the code side of things.
Go to settings, scroll down to safari, tap it, go to "Motion and Orientation" and set it to on. That fixed mine....
So for fun I tried it on the ipad and iphone. Not seeing anything funky. Y'all may need to check the mushrooms being used in your sketti sauce or something
