That sounds nice, now I just hope it 's not an empty promise that this doesn't use an filter-overlay.
Did you try the manual calibration (Custom-Settings)?
A before (=disabled) and after (=enabled e.g. with RGB set to 100 200 255) screenshot of a 100% white or white to black gradient would be really nice!
Anyway - thanks for confirming!

Hey, thank you for the discovery.
I can confirm you that is not an overlay. The screenshots made with the filter applied remain the same than when the filter is disabled.
I was using CF.lumen with its driver to use custom RGB values. The same happens with it, the screens are the same with filter and no filter, so neither of the two use overlays.

... seems to be not as easy as with Qualcomm due to the lack of KCAL support. There also seem to be no Kernels around for Exynos variants where anyone has ever managed to do this (as far as I found out, correct me if I'm wrong)
So far I only found one clue that is not using the usual Color Filters but seems to be changing the RGB values directly ...
In an older review someone reported that this app was working with older Exynos SoCs for them:

Apparently it should also work for Android 6 - as I do not have root yet can someone test if it does work with the S7/S7 Edge Exynos variants?
Otherwise we can only hope for Samsung to include Color Calibration from Android N in their official release (if they aren't to lazy and simply remove that feature)

The Pro Version [v1.11] worked perfectly on my Exynos S7 Edge. {requires root}
Thank you for this! :highfive:

Is this the reason why J7 prime uses a tft instead of a AMOLED screen?

low touch latency on redmi note 7

I wonder do anyone else face this problem?
When i scroll through things, it seem to lag behind a bit. I also tried to compare it with other phones and this phone seem to have a much higher touch latency than the others.
Anyone facing similar issues on this phone?

I have the EEA version of the phone and nope, no troubles at all and the touch is so responsive and smooth ?

The same problems here, Global version.

same here, global variant RN7

What's the EEA version? And have you tried to compare it with other touch monitors?

Mine 4/64

Same problem. Very frustrating. RN 7 global version, 4/64gb

Yes, me too. Especially annoying when typing - keyboard is very laggy and driving me crazy.

I had the same feeling on my old crappy Mi A2 Lite. It was much better after switching to a custom Kernel (Butterfly Kernel).
Now I have the 128GB Global RN7 and touch responsiveness feels just fine. No problems at all.

what MIUI version you guys use?
some people who use miui 10.3.5 global rom have possible same problem with yours

What miui version are you on?

So far, my Global Version 3 day old RN7 on 10.3.5 doesn't seem to have bad touch latency.
Was nervous about that considering this phone is my first Xiaomi device.
So far so good.
Have you all tried using the old Touch Screen Booster app? Not sure if the apk is still on the Play store.
Try the app if you can. It fixes a lot of touch sensitive issues without root.
Won't make your phones touch response iPhone level smooth but it will fix whatever ailments you're having

I have the RN7 Global and not facing any of the problems people comment about the phone... No lags, no video rec problems, no battery drain, none of all...
My guess: We would face palm us hard if we knew what apps some people install...

Man... Sorry to hear.
Is the app the one that's got the neon green color icon?
If that doesn't work your digitizer could be defective or the update to 10.3.5 could have altered how your touch input functions.
If that's the case, you could also try both touch screen repair and touch screen calibration apps.
Unlike SGS, they're both paid apps in the app store that should help improve your touch response without root.
I used both on my honor 8 and can vouch they improve touch latency response on our phones

I also tried those and they say my original latency is around 47 ms, which is quite okay by this number, but it just doesn't really feel right. Everytime i scroll something, it just seem to lag behind quite a bit unlike other phones. Just tapping on things seems really fine though, no delay for that. And i also went to the store today and tested the demo there. I found out that the demo also have a similar problem. Can i conclude that this problem is not a defect for my phone?

Not sure.
1. Are you also on MIUI ver 10.3.5?
2. Was your touch response ever working fine beforehand and the latest update broke it?
3. What other phones are you comparing the RN7's touch response with?
For me I'll answer:
1. Yes... But I find then touch response the same vs the prior version of MIUI that was on my phone right before it updated to 10.3.5
2. See my response to #1
3. I'm comparing the touch to:
IPhone 6s(which is still the fastest touch response to date), Honor 8 which was great but with the apps above, touch latency/response improved and Galaxy S9+.
I find Redmi Note 7 is slower than our iPhone 6S, close to my Honor 8 with the apps mentioned in the previous post and on par with the S9+ I played with in store.
I found that bizzare since AMOLED screens typically have faster touch response vs IPS/LCD etc.
What are you guys seeing?

Dark bleeding - 1 month old

Hello guys, I'm new on Mi 9t, I have it since one month now.
I'm running 11.0.5 global (waiting for miui 12) and everything is working smootly (a part some heating problems and battery drain).
Yesterday I noticed a BIG strange spot on the right side of the display only when I have a black/dark theme (for example on Telegram) and when brightness/light around the phone is low.
I tried to googled it but I didn't find anything useful and still don't understand if it's software or hardware. I just get that is a common issue of AMOLED screen but in 2020 I don't get how this is not fixable lol.
Any suggest?
Thanks in the advance and I wish you a happy day!

Nope, every AMOLED is like that. Tested even on the S10 plus. No worries

Gonna have to provide a picture (if it shows) to see what you are trying to describe bro.
