Poor resolution with 960fps is normal. Change to 240fps for normal slo-mo.
You use iMessage but outside the US, no one really uses it.
Both are things you could have known before buying S9+.
If display is really you're issue than wait for possible fix, or buy Note 8 instead. If you already have iPhone X, I understand your decision.
But there are some things I noticed to this black crushing and that it's not always present under different circumstances (still the same device). So I hope it's software related. But on the other hand I see that some devices have more issues than others so that implies it could be hardware related.
Let's hope Samsung will investigate this issue and come with an answer.
Yeah I'm not saying I was shook by iMessage not being there, I'm sayin that "eh if these other issues exist it makes iMessage another reason to go back instead of an obstacle to over come to stand firm."
I do already have the X. I'm more bummed than anything because theres a lot to like abour this phone. The slo-mo thing is more about my videos having a lot for the camera to compose, waterfalls in a forest during a snowfall. Scenes of like a match being lit look better.
They are calibrated that way. My thing is, who cares what the branding is, I dont pledge allegiance to a brand. Apple has the best all around display in the game right now. True tone, accuracy, none of this gradient or crush stuff. It's on point and it is what it is.
