Horrible touchscreen latency / lag / delay

[Frakatchoo]

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?

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.

Nope, still there.

Nope, still there.

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 :/

Hello, got the same problem. I am on CLT-L29 8.1.0.106(C432). However, the screen is perfectly responding when drawing on a picture from Gallery...

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?
