Is HDR10+ working for you? - Xiaomi Mi 9 Questions & Answers

Hello everyone,
I am in Xiaomi.eu and when I try to play an HDR10 video in youtube the screen blacks out and only sound plays. The touch screen is responsive so if you know the taps you can close the video and the screen will work again but I really want to see the difference in HDR content. Is it a Xiaomi.eu problem, or a general bug? Thank you in advance.
SOLVED: I do not know if this is a problem with the original MIUI but if the Contrast & Colors is set to Automatic contrast HDR works. I used standard contrast and that was the source of the problem .

When looking at a video on Youtube, HDR "visibly kicks in" (screen changes color temperature) and is visible in Youtube Quality settings.
The problem might come from the Xiaomi.eu rom or a setting.
BTW, you should assume, when using a custom rom, that it's always the origin of the problem, and ask your question in another way, like "Anyone on custom rom has hdr working" instead of thinking that it must be a Youtube bug lol

Recording with constant framerate (LOS)

Hey guys!
I'm currently using nvertigo67's LAS for the 1+3T, which comes with OOS camera pre-installed.
It works extremely nice, except for one thing. It does record 1080p in 60fps, however with a variable framerate. I asked the dev. if he knew any way to change it to record at a constant 60fps, to which he said he doesn't know much about changing codec settings (post 1 & 2)
Do any of you know what I should try to do to be able to record with a constant framerate?

use a camera app where you can lock the ambient brightness like open camera. then try to lower the ambient brightness shown in the camera by holding the camera to a bright spot and press on the lock. this changes the iso so the framerate rises and by locking it it will stay on that framerate constantly. ofc you can also use a camera app where you can choose between different iso values.
but for me oss camera has allways same framerate no matter what light conditions. your issue might be kernel related. low performance maybe. or some apps consuming cpu in the background

I have tried Open Camera, unfortunately it doesn't go above 30 fps, even when selecting 60 as the approximate frame rate.
The developer told me it's how the encoder works (please see "post 1 & 2" I have linked in my first post, he explains it there pretty well.)
OOS camera worked for me well too, while I was actually using OOS. The AOSP camera doesn't support 60fps recording either.

saturated colors when playing videos

Hello, who knows how to get rid of automatic color popping mode when playing videos, i ve noticed it on youtube.
Possibly by going into Setting>Display>Color mode & Temperature and change your color settings through there.
Yes despite activating normal colors setting, the color turns satured automatically when playing a video. That is a huge limitation. Weird from huawei

Looks fine to me, but I would blame the app writers.
Seems like the Video Enhance mode on Samsung S8/9.

HdR on Netflix and Youtube not working?

Hello there.
It seems that HDR is not working in YouTube or Netflix although i get the HDR logo in Quality settings (YouTube) or next to the movie duration (Netflix).
The brightnes does not seem to change like it should even though the slider is on maximum and the image does not 'pop' for example in bright scenes.
I have a Xiaomi Mi8 to compare it to and side by side there is a huge difference and the Mi9T pro should have a slightly better panel. It just does not look like HDR mode is enabled on the panel itself.
I have noticed the same thing on 3 other devices like mine.
I am on MIUI Global 10.3.4.0 on Android 9.
Has anyone else noticed that or is it just me?
HDR
I have noticed the same things and maybe there is something wrong here as I have seen in other phones that reading mode does get disabled.

Color banding in HDR videos.

I don't know if my unit is defective, but on HDR videos (Youtube, Netflix, Mi Video, MXPlayer) you can see a lot of banding in the blacks and the jumps between colors (the dark scenes look very bad). I only found that this also happened to the Samsung S9 but they fixed it with an update. Can anyone check their unit with HDR videos with dark backgrounds? Thank you very much.
Mine Looks Great . Maybe you've got a bad unit
At night times dark videos looks like having some kind of noise.
I don't know what's the prb.
Are you on a custom ROM? I had these problems on pixel experience for the mi8

How to fix oversaturated youtube video?

I've noticed that my display's brightness automatically increases and gets oversaturated when viewing videos on the youtube and twitch app in fullscreen. When the videos are playing in portrait mode, display is normal but once the video is switched to landscape mode the oversaturation happens and this doesn't disappear even if you switch back to portrait mode...Display reverts back to normal only after exiting the video.
This effect seems to be subtle in lifelike videos but becomes really apparent in gameplay and other animated videos. The twitch streams look so cartoonish that it is impossible to enjoy gameplay streams on my mobile. Fullscreen videos from Chrome browser dont seem to be affected by this.
Is anyone else affected by this? Is there any solution?
Two things I recommend disabling if you encounter this:
- Under display, go to "screen colors/pallet" and change it to whichever color temperature you prefer (automatic is enabled by default)
- Check if you have "reading mode" enabled

I've already turn off the reading mode and choose screen colors to automatic but its still seems so oversaturated or its just software bug?. But if iam watching it on 1080p its just like hdr video
I was recommending you to disable automatic colors, that's why I believe colors are too saturated, you can change temperature too if you want. Sorry if I wasn't clear.
