Horrible touchscreen latency / lag / delay - Huawei P20 Pro Questions & Answers

Hi !
I recently bought the P20 Pro and noticed a big issue concerning touchscreen lag / delay / latency. same problem as on honor 9:

Playing FPS or PUBG that requires precision becomes completely unplayable.
Do you have this problem? Any solution?
THX

I am experiencing the same issue as well, noticed it initially in pubg.
Any luck solving the issue since posting? I suspect it's related to the firmware though.
I am now considering returning the phone due to this issue, real shame because I really like everything else about it.

Maybe related to: https://www.xda-developers.com/android-8-1-oreo-multi-touch-bug-fixed-june-update/

Not sure, it's not a multitouch problem. But more a single touch issue with some delay/latency. Hope a new firmware can solve this.

Does anyone know if the normal P20 has the same issue? Thanks.

I just installed it, got it on ultra and no latency problems. A bit of load lag but thats the gpu/cpu

Ok thanks, I'll go to my local store to try the P20 and maybe considering changing my P20 Pro, my 2 years old 150€ Redmi Note 3 has no issues like this, such a shame...

I learned a lot owning Huawei, I always go through the initial setup then factory reset it before I put my Sim in and my p20 pro has 0 lag issues.... It's on the C605rom

remove the double knock for Screenshot gesture, Touchscreen issues are gone.

After removing all double or knock gestures, still Touchscreen issues?!
for me after that, touchscreen works perfect, no issues or latency

I turned off the 3 settings but the issues still there, try to make really tinny circles on a zoomed webpage and you will notice it.
EDIT: if you have some apps using a slider (I'm using Deezer), you will notice you can't be precise, I can't manage to easily set the Smart Cache value in Deezer :/

Same issues here, I tried to draw something and I don't know if it's the normal behavior but can't make a simple dot.

You are right, simple tap is not detected for me too. Impossible to work with precision (Citrix...). I have send an email to Huawei customers service. I let you know

I have the same problem, but only at the edge of the screen on my P20 pro. Later I will check on my wife's Honor 8...

I checked on my wife's Honor 8 on Sunday and no issue. It seems Huawei ignored the issue with the Honor 9 so we probably won't have a fix.

Nothing interesting from Huawei support. They send me back to my retailer. I will compare with p20 Pro at store.

Scrolling seems to behave slightly strangely - it stops moving almost as soon as I remove my finger from the screen so there's no real inertia or acceleration. Is that standard for everyone or is it related to these latency issues - my old S7 Edge scrolled much more freely?

Video screen rotation stutter

Just picked up my new p30 Pro. Really pleased with it, but has anybody noticed that when playing videos in the video app or YouTube, when you rotate the screen the animation is stuttery as hell. Wondered if it's just a problem with my phone. Am on firmware 124. Thanks

Have you resolved this issue? It's driving me crazy, to the point I want to sell the phone. Never seen this on any phone before, being a Android user for at least 10 years.
I'm currently on .178 and no update is helping.
Have the same issue... Would be great to make it quicker...

The v193 firmware improves this slightly but it's still far from smooth. Oddly, for me if the phone is on charge then the rotation animation is smooth. To me this seems like its definitely a software issue. Probably some kind of unintentional power saving method in the kernel.

Popup Camera sided LEDs cause visual problem on LCD

Got my mi 9t pro weeks ago, after around 2 weeks of using when I open the selfie camera it shows the LED lights on popup camera on screen as well! which is annoying cause the phone is new with no problem(well atleast software-wise)
here is the clip of the problem
https://media.giphy.com/media/frGbhK6J30aSNADl4u/giphy.gif
anyone else has this problem?
pretty sure its not normal lol
yes don't worry dude it's just a animation
Lol, it came with miui11, it's a software "feature" xiaomi devs thought would be cool.
Little bling bling, you no like?
No worries, it's not a hardware problem.
Just find in settings / additional settings / front camera effects.
You can turn off this, sound and led even.

Yes outdoor you can upgrade, the biggest upgrade is the Android 10. We must be proud that our device for it so short than many other phones. Also work MIUI 11, the phone overall performance has imported. I am also getting better battery backup in MIUI 11.

AMOLED SCREEN

For the last 2 weeks i have identified an issue with its amoled screen. Under low light condition, with brightness level at its minimum, and with dark gray color as background (e.g. Dark mode in facebook), I noticed some lines of black and white which irritates my usage. I compared this with my mate 20 pro and I have not seen any of it. Iv tried to look about this in the internet but Im not sure. There are articles that say its banding, some say glue gate issue. Any thoughts?
I have the same issue!

I just spoke to Huawei Support here in Sweden.
They hadnt heard about this problem yet but they promised to check it up and get back to me.
I also informed him about my camera problem which is that pictures taken in normal cam mode ends up brighter and HDR like. This is not a problem on my mate 9 and mate 20.
Only way of getting pictures right is to switch to pro mode or change the filter....
Will go to service center tomorrow

Jolly good, mate!
But it would be nice knowing what kind of display they will replace with... Hopefully Samsungs or LG's.
I hope Ill get mine fixed. They pain is to start all fresh from scratch after though... Even with backing up Ill always end up having to manage my themes, icons, Apex launcher, modded apps/games, game data from Super Clone etc. Not to speak about Dual Space app(s), Google Play Storet etc etc....
Hmmmm...
Last night I discovered another screen/image issue...
I have a photo of my son as wallpaper. When I lowered the brightness to minimum (in a dark room), the photo looked like a 8-bit coloured photo from the 80's... Low colours, high contrast and looked like a sketch!!!!
Yes, it looks like hell and when you close it completely too ...
Why would you keep the screen with brightness to a minimum ??
Almost nothing can be seen ...

Just wonder how to explain properly for Huawei support here in Sweden in order for a replacement. They still havent got back to me yet......
Any updats about the screen issue, Zaxarive?
Huawei support, Sweden just called me.
1. They will escalate the issue with the camere higher up and get back to me.
But I guess the issue with "brighten up"/processed images from "normal" camera mode is caused by Huawei's new feautre "Ultra vision/Cine"... Never the less, it would be nice beingbable to turn it off when needed. I mean the whole thing just basiclly feels like a "HDR function", something that on iPhones have been a feautre the past 10 years. Apple lets you turn it off/on...
2. Most likely our problem with our displays in low brightness comes from having a OLED instead of a Super AMOLED... It just works in another way... Pity but the truth..! OLED has a much better blackness BUT with the costs of much harder to get a "sharp bright" image i low brightness mode....
Ill let you know when Huawei Support has got back to me.
Few months after any update?

Got my X5 Pro Yesterday impressed with 1 annoying bug refresh rate in Google apps...Some of.

Hi,
Loving the device so far, Very slick and the build quality is awesome, Camera is excellent! Better than I imagined for a Chinese phone, It feels almost like the perfect smartphone, I'm glad I chose this now and not the OP 10 Pro.
1 annoying issue I have though is scrolling refresh rate in Google photos and the menu scrolling in Google maps is jittery.
This is not present on my 8 Pro and I have no idea why, It makes using Google photos quite a horrible experience to be honest, I can't find a way to force higher refresh rate for specific apps alao, Doesn't look like it's possible.
Does anyone know how to report bugs to Oppo?
Update...
Weird lol just gone back into photos and now it's smooth I have no idea why, What it is still doing though is mis touches with the screen and scrolling, It's nowhere near as fast as my OP 8 Pro and does not seem to be as responsive either in the sense that trying to scroll fast with your finger results in mis touches of the screen not picking your finger up, I hope they are aware of this and it gets fixed soon.
Update again lol, Scrub that it's not smooth in Google photos at all I posted this from my 8 Pro not even realising lol.
I have none of those issues on mine, have refresh on auto.

Auto refresh? There is no Auto refresh it's either standard or high? So the YouTube app is running at 120hz on yours is it?

Sorry I meant high, no I'd say it was definitely 60 when you scroll, but as YouTube has no 120hz content it's understandable.

Thanks mate I'll give that a go sounds promising for now, I can't understand what is so difficult for the the software devs of these modern flagships to have YouTube and Google apps running at 120hz, After all it's what we paid for with these high end displays, Thanks again.
I know. It's a pain. My previous device was an s21 ultra and had no issues with 120hz. I guess oppo do it for power saving maybe. I'm pretty sure one plus do something similar. Try the app worked for me. You'll have to go in to the app every time you restart the device. So it's not a permanent fix but gets the job done.

Yeah they must not do because surely people can't be happy with 1 speaker audio and low refresh in major apps, Doesn't make sense, It completely ruins the immersive experience in COD mobile can't hear footsteps or where people bare coming from.

Question Stuttering and frame drops while video recording

Anyone else having frame drops and stuttering issues while video recording in Xiaomi 12 Pro ? I've already got the motherboard replaced from service centre still having same issue.
It mainly occurs if my device is overheating or close to it. Also when I zoom too fast while recording. Though it's not so much of an issue that I'm upset with it or anything. Machines have their limits.
Each and every video I came is full of stutter. No clean videos are coming out. Even it's not hot not do I zoom. I'm totally upset with it
You are not alone. Me and my significant other have both 12 regulars. Video recording is set on 4K30 nothing fancy. Each and every video has some dropped frames or some sort of stuttering. Really annoying.
Thinking about switching but there is nothing with same or comparable specs in this form factor. Really like Xiaomi though, would like to get this fixed
Had this issue too on my xm12pro (china). I figured out that it was WAY better when I switched from Xiaomi.eu rom to the official Xiaomi global Rom.
Anyways, it reads like you are on the official ROM, as your Mainboard got replaced, so I don't know if this is helpful for you - but maybe for others
We're on EU official ROMs also. I've tried everything. First approximately 5seconds a f video recording is stutter and frame drops. Switched both phones to performance mode bit that didn't help also.
I don't have this problem, what are your settings?
4k30 with phone running on performance profile. MME +3GB enabled as default, tried to disable that once to see if it's a memory issue, but nope.

Whether with a stock rom, Miui 13 A12, Miui 14 A13 or Xiaomi Eu rom never had this problem and the same with 8K.
Could be a faulty series..
What I would try to be sure and certain that it is a Hardware problem, use Miflash and flash a Stable Global rom. (V13.0.9.0.SLBMIXM) be careful if you have a Chinese version.
EDIT:
Have you tried setting the screen refresh to 60Hz/and lowering the resolution(FHD+)?
Just got the 13.2 and same thing. Two phones with the same problem? That's not very probable
The two phones are purchased different times.from different vendors also.

Something with codecs then perhaps? Also, Gcam might not have full API access but it definitely makes better photos during low light.
But yea, all videos uploaded or send to different devices are totally useless in my device, no matter the ROM. Only videos recorded with Gcam are okay. That is all I know.

Not really, 12 regulars doesn't mean anything, on the other hand Xiaomi 12 CUPID is precise or ZEUS,DAUMIER,DITING,,EARTH,MAYFLY,PLATO,PSYCHE,TAOYAO,UNICORN,THOR,all series 12.
None have the same characteristics.
Some problems may be common, others not and remain version specific.
This is why there are threads for each device.
Contrary to what you say the 12 pro Cn can have this problem.
Answers but no solutions, send it back as warranty.

The service engineer first changed my camera and gave me the phone to test but the results were same as before hence I asked them to change the Mobo. But still no difference. So I guess no hardware issue only software.
