Shocking , shocking

I can't believe I just came a cross this website so useful. Anyway I picked up my p20 pro today as I broke my screen on Samsung s8 so went for an upgrade (or so I thought)

I regularly play Golf clash on my mobile devices so loaded it up on the p20 pro and went to play it as I normally and it was so innacurate and laggy that it was unplayable on that phone so I went on to the main screen and noticed if I pick up the apps to drag and drop them I have to move my finger a few mm before it even realises I've actually moved my finger! So shocking to say the least this relates to everything you will do on that phone and have to say I can't believe they wouldn't spot such an innacurate problem.

Compared to my s8 the touch response on that is silky smooth and like lightening in terms of response times.

I will be taking my phone back and changing it for an s9+ which I'm gutted about as I liked this phone.

On paper this phone is the mutts nuts but in reality it's slow and laggy because of the crap software. You can't rely on a company that doesn't offer frequent updates to get these issues fixed. I feel sorry for the people that actually use a stylus with the p20 pro it would be a disaster and such a shame.

If anyone does find a fix please share it .

Did you by any chance have the high contrast ,smart resolution or similar accessibility mode on? I've turned that off and it seems much better will keep monitoring ...
[Huawei P20 Pro Questions & Answers] esiemi:
just compared it to my s7 edge, s7 edge is very accurate, p20 is a joke, what worries me is that this seems to be system wide, same delay in browsers, youtube app, games, launcher etc, and tbh i think this is a hardware issue.

thinking about sending it back now, dont really expect a flagship with this sort of problems

look at this https://www.youtube.com/watch?v=vOvQCPLkPt4 i think they cut the corners and used a cheap digitiser
[Huawei P20 Pro Questions & Answers] cheetah2k:
I had the same issue on the Xiaomi MI6. Seems this is a China phone issue. I complained a lot in the Xiaomi forums, but after 7 firmware updates nothing was fixed. I sold the phone and will never buy another Xiaomi again... You can see here, the problem I had is replicated in the Huawei P20 pro...

https://youtu.be/USjIw8Nn6yw

BTW if you want a phone that is awesome for gaming then buy the LG V30 . Zero lag, zero delays, and super quick.
[Huawei P20 Pro Questions & Answers] Teezj:
I tried downloading those app to fix it but it didn't help in the responsiveness of the screen. :(
[Huawei P20 Pro Questions & Answers] chillasfolk:
Oh sorry i found out its still lag in certain apps like whatsapp , but others are okay. Just okay but not v v responsive. The lag in whatsapp is still serious. I saw in other china forums there maybe 108 firmware on this issue by end april
[Huawei P20 Pro Questions & Answers] Teezj:
Thanks for the update. I hope Huawei can roll out the fix soon.

Also after 1 week of usage, I found out that the phone will auto go back Home Screen when you are typing on Facebook, WhatsApp, and etc.. Did anyone experience this issue?
[Huawei P20 Pro Questions & Answers] chillasfolk:
Ya its a very widely debated on china forums and they said the engineers are on it (hope so). Ya i reli hope that coz everythg else is fine, maybe i will try some other screen protectors to see if it gets better.

Nopei didn't experience that
[Huawei P20 Pro Questions & Answers] a500user2013:
I think the auto go back to homepage issue is caused by brushing the middle virtual hardware button when pressing space. I've done that a few times ....
[Huawei P20 Pro Questions & Answers] Teezj:
Agree everything is well except for the touch screen. Hope they will settle it really soon. Battery life on this phone is really pretty amazing. It doesn't drain much over the night.

---------- Post added at 04:12 AM ---------- Previous post was at 04:05 AM ----------

Thanks for replying. I guess the touch sensor between the keyboard space bar and the virtual home button is either too sensitive or inaccurate. I have a LG G4 with me which have the same virtual buttons but didn't have this issue.
[Huawei P20 Pro Questions & Answers] Minallanmin:
It's definitely software, if you activate the "show touches" in developer options you can see how the touchscreen detects your finger moving(before starting to scroll). I hope they fix this ASAP
[Huawei P20 Pro Questions & Answers] chillasfolk:
Its in 108 updates, tackling scrolling issues, but only for mainland versions currently, wait a bit more
[Huawei P20 Pro Questions & Answers] chillasfolk:
Saw ppl say the lag is improved, seems solved View attachment 4484888
[Huawei P20 Pro Questions & Answers] Jonathan-H:
If you edit a photo in gallery and draw on it, the issue isn't there and it draws as soon as you move your finger so I am really pleased to see it's probably solved in an update. It's the only thing troubling me with the phone! :D
[Huawei P20 Pro Questions & Answers] Teezj:
Thanks for sharing the screenshot with us. At least now we know our device will be fixed. I would to know which site did you visit that shared all these Chinese update information?
[Huawei P20 Pro Questions & Answers] Link69:
http://club.huawei.com/thread-15774126-1-1.html

Nice, waiting for the global update and feedback to decide whether or not I'm buying it again.
[Huawei P20 Pro Questions & Answers] kungcoopa:
Hi!

Any news regardning the release of the 108 update?

I live in europe and are waiting to see if the screen lag is resolved before buying the device.
[Huawei P20 Pro Questions & Answers] David Horn:
Roughly 4mm of finger movement needed before it starts scrolling on 8.1.0.110. Once it's started scrolling it seems to be pretty sensitive.
[Huawei P20 Pro Questions & Answers] hunhool:
I didn't know whats this topic is about until I watched your video on YouTube. Now I can confirm, my device (P20 pro) doesn't have this issues at all.
[Huawei P20 Pro Questions & Answers] kungcoopa:
Ok so this issue doesn’t seem to be software related then? What firmware are you running on?
[Huawei P20 Pro Questions & Answers] hunhool:
clt-l29 8.1.0.107(c432)
[Huawei P20 Pro Questions & Answers] NeverNice:
I have no Idea what to do now. Keep the Phone and hope for a Fix or give it back and go for a Samsung S9+ :confused:

And its not only the Touchscreen its also a Software Delay!

Same problem with the Honor 9 so i dont think they fix the Problem :(

I have Uploaded a Video on Youtube but i cant Link it here because im a New User. Search for "Huawei P20 Pro Touchscreen and Software Delay"
[Huawei P20 Pro Questions & Answers] Link69:
Heard it had been fixed with 108 in China, but I already returned mine and bought an S9, can't wait with such an issue as a daily driver phone.
[Huawei P20 Pro Questions & Answers] Allesa:
Had trouble swiping keyboard, it sort of skipped a letter then resume the swipe, resulting in gibberish
[Huawei P20 Pro Questions & Answers] frewys:
Just got my p20 pro today

No latency

No maps issues

So far so amazing

L29 c636

Build 107

?
[Huawei P20 Pro Questions & Answers] esiemi:
To all that say have no problem, could you post a video showing us that there is no latency so we can forward to huawei. Thanks
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
This Is my main issue. Don't play games or notice too much in scrolling but the keyboard is a massive problem
[Huawei P20 Pro Questions & Answers] kungcoopa:
If someone without problem could do this it would be very much appreciated since I almost think that every device has this problem, and some users just don’t notice it. I’ve been to several shops and tested out the P20Pro and all has this issue..
[Huawei P20 Pro Questions & Answers] Allesa:
I sell phones, including p20 pro. Secretly when my buyers buy p20 pro I test out their units. All have this problem out of the box.
[Huawei P20 Pro Questions & Answers] esiemi:
does that include the dual sim version? last couple of people that claim to have no latency here have dual sim.
[Huawei P20 Pro Questions & Answers] Link69:
I think there's no single SIM units. Mine was dual SIM and I had the issue.
[Huawei P20 Pro Questions & Answers] Teezj:
9

The problem with my phone is it will home itself while typing on the keyboard. It probably due to the inaccurate touch sensor. The only way to solve it to switch off the virtual navigation bar which I heavily rely on.. Damn irritating...

---------- Post added at 03:38 PM ---------- Previous post was at 03:34 PM ----------

I'm using the dual sim version and yes it is affected by the lag. I went out to try other units, all have the same issue.

---------- Post added at 03:39 PM ---------- Previous post was at 03:38 PM ----------
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
S9+ is starting to look better and better, such a shame because I really like the phone otherwise
[Huawei P20 Pro Questions & Answers] Teezj:
This will be a perfect phone when the huawei roll out the fix.
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
I wouldn't hold my breath for a fix, looking online this has been a problem with Huawei phones for a long time.
[Huawei P20 Pro Questions & Answers] esiemi:
Not waiting to see if they fix this. Returning the phone as still within return window.
[Huawei P20 Pro Questions & Answers] NeverNice:
I have made a New Video where i compare the sensitivity from a Huawei P20 Pro and a HTC One M8

www.youtube.com/watch?v=c5YZ2aJpUoA

Its the same with the Honor 9 so i think its a "feature" from EMUI and we will never see a fix for this! I will return my Phone as soon as possible because this is a no-go for such an expensive Phone

https://www.youtube.com/watch?v=6h645V_GLuQ

The Phone is so damn sexy (Twilight) and i love the Camera but this "feature" is not acceptable..
[Huawei P20 Pro Questions & Answers] dannejanne:
Not all Honor 9 had the issue. It was digitizer differences. I had two and one had good scrolling the other bad, both in same firmware. To my knowledge all P20 Pro has the issue and should be rectified.
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
Unless they used cheap components
[Huawei P20 Pro Questions & Answers] NeverNice:
The Problem is that people are keep saying they dont have such an Issue. I bet Huawei dont even know about it or they dont care because just a few people are aware of it. I only found this Thread about it and just one Video on Youtube. So why should they work on a solution?

I wouldnt recognize the issue by myself when i didnt played PUBG Mobile on my HTC One M8 before. People who dont play this game or dont need the very high sensitivity dont recognize it.

And sometimes the people dont even care about it like you can read here! https://xdaforums.com/mi-6/help/touchscreen-delay-experience-t3617252 (this phone has nearly the same issue)
[Huawei P20 Pro Questions & Answers] dannejanne:
There's one guy here in the forums that claims it has been fixed in chinese firmware after people talked about the issue in a chinese forum and posted an image of the changelog. But I can't read chinese.
[Huawei P20 Pro Questions & Answers] NeverNice:
Yeah and there is only one guy who posted this Fix on reddit in English.

https://www.reddit.com/r/Huawei/comments/8f23eq/p20_pro_system_update_cltal00_810108sp3c00/

I would not believe it in the Time of Fake **** everywhere. Its not like they only sold 100 Phones. There must be more Information about it!

Very strange part is "Improves performance in Playerunknown's Battlegrounds Mobile: Battlefield."

The Problem is not only in this Game and why should they mentioned only ONE Game in a System Hotfix?! That makes no sense lol aswell as "Optimizes the resonse speed when sliding across long images." Thats not the Problem here!
[Huawei P20 Pro Questions & Answers] user4001:
I think this might just be Huawei's idea of the best scrolling implementation. It's not actually too bad when you get used to it but I'd still prefer more instant responsiveness when scrolling.

Not a dealbreaker for me but maybe it will become one in future. Thankfully I'm not really a gamer (Although the FM2017 game I do play doesn't have accurate touch points. I have to aim a bit left of where I want to touch - i put this down to the weird aspect ratio of screen and old version of game, so no biggie).
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
I doubt I would have noticed had I not tried to swype keyboard
[Huawei P20 Pro Questions & Answers] NeverNice:
I was at some Stores now and tested a few P20s. All had this Issue. The P20 Pros and normal P20. The P20 Pro had a 112 Firmware on it and the P20 a 103. So they dont fix it with the next Fix!

BUT the P20 Light didnt had this Problem. So i guess its not a cheap Digitizer its a Bad Android 8.1 Version because the P20 Light has the 8.0 Version.

I also talked with Huaweis Customer Service and they said they dont know about the Problem. Im the first one who called them because of this Issue! :/
[Huawei P20 Pro Questions & Answers] AndiThebassman:
I would really like to know how bad this issue is on a daily basis. Tried it at a local store and the issue was there. Had tried it before without knowing of the issue and I didn't realise there was an issue. I'd like to have that phone because of its camera and zoom functionality but don't really know if the touchscreen latency is a deal breaker for me or not
[Huawei P20 Pro Questions & Answers] Mixy:
It is definetely there, and given the opportunity I'd swap the phone in a heartbeat.

With that said I don't notice it that much during regular use. Its noticeable during scrolling and if you are gaming FPS it will be useless.
[Huawei P20 Pro Questions & Answers] AndiThebassman:
Really not sure what to do because I would really like to have this phone. Hope they fix it with an uodate. Fingers crossed
[Huawei P20 Pro Questions & Answers] NeverNice:
yeah me too! I really really love the color (Twilight) and the Camera Zoom is just awesome but i dont really want to wait for a Fix. Maybe they never fix it or it takes too long. Atm its just PUBG where i have a Problem but maybe there are some more Apps later i will have a Problem with .

You never know.

I cant decide what to do now. Keep it or buy a Galaxy S9+ :(
[Huawei P20 Pro Questions & Answers] Mixy:
Well according to some users its fixed in Chinas 108 firmware, and we are seeing newer firmware in testing for Europe. I'm not holding my breath.

There are several other factors that makes me want to drop the phone, but thats not due to this delay:

- Camera AI/Sharpen/Beatify is too much no matter the settings you use. Only option is to use RAW which is which has its own problems.

- EMUI has made a lot of poor choices imo for no apparent reason over AOSP. Each to their own I guess.
[Huawei P20 Pro Questions & Answers] tsiglas:
I have p20 pro European 107 version and I have tested the screen to see latency delay... First I notice some delay in scrolling but not so much as the video in this thread... After that I have desable "glove mode" and try again... After test it at the same time with my wife's S7 edge there was zero deferent... No problem at all... I'm not sure that glove mode is responsible for scrolling delay but I'm sure that I'm happy with my phone... Before I had S9+ together with P20 pro and I deside to keep p20 pro... I'm very happy with my desision...
[Huawei P20 Pro Questions & Answers] AndiThebassman:
I've tested it extensively in another store now and I think I'm gonna take it. The lag was there but it wasn't really a problem for me an while editing pictures there was no lag at all (I think it was on 107). Otherwise I really liked the feel of it and I'm still a fan of the fingerprint sensor on the front that doubles as navigation Button.

The big battery, the zoom and night mode and the fingerprint on the front sold me :laugh:
[Huawei P20 Pro Questions & Answers] thayil:
I have the same issue as well. Don't you think that it could be the original screen protection that is causing this issue? As I want to sell my p20 pro for a pixel 2 xl I don't want to remove the screen protection.
[Huawei P20 Pro Questions & Answers] Mixy:
It's not. The movie I made in a post earlier is without the protector
[Huawei P20 Pro Questions & Answers] kungcoopa:
Can someone else please try this and confirm whether it fixes the problem or not?
[Huawei P20 Pro Questions & Answers] Mixy:
Checked mine and it's off, afaik I've never had it on
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
This, combined with the abysmal Bluetooth performance, completely ignoring the l09 and awful sound quality is probably going to do it for me.

Looking at other phone options.
[Huawei P20 Pro Questions & Answers] Keshigami:
I have tried mine.

The lag and latency issues was resolved by a simple factory reset.

I had an update 2 days ago. Then made a soft factory reset
[Huawei P20 Pro Questions & Answers] varignet:
I have exactly the same latency on my honor view 10 which I'm trialling and thinking about returning.

it's emui 8.0 on Android 8.0.

I know it's software because enabling draw pointer under dev options shows even the most subtle touch being recognized straight away.

I suspect you'll notice the same on the p20pro.
[Huawei P20 Pro Questions & Answers] AndiThebassman:
The hardware works perfectly fine. While editing pictures I could draw lines that started and ended exectly where I touched the Display. So definitely a software "issue"
[Huawei P20 Pro Questions & Answers] NeverNice:
Thats what i said :D We all did a simple factory reset and we also have the 107 Firmware and we still have this Problem! Also Devices with a 112 Firmware have it so yours still have it! Or what Firmware Number do you have?

Make a Test with the Multitouch Tester App and you will see. The P20 Light version with Android 8.0 dont have this Problem but the P20 and P20 Pros with Android 8.1 have it.
[Huawei P20 Pro Questions & Answers] paul678:
Recorded a short sample in my P20: black C432 with no screen protector and on the latest official fw for P20 .110. To me there seem to be no lag but maybe I'm wrong. Can someone with the problem do a short recording like this? (The no. 4 finger was disappearing because i wasn't touching the display properly)

https://streamable.com/pq640
[Huawei P20 Pro Questions & Answers] NeverNice:
There is no "lag" when you do big movements like you do in your Video. There is no lag at all but just a small "deadzone" when you move your finger (pen) just a little bit like you can see here

https://www.youtube.com/watch?v=c5YZ2aJpUoA
[Huawei P20 Pro Questions & Answers] AndiThebassman:
That's exactly what it is. No lag but a deadzone. If you don't do little movements you won't even notice it.
[Huawei P20 Pro Questions & Answers] paul678:
Hmm indeed there seems to be a "wait distance" before the touch functions properly. The time in my video that the pointer does not move is while I'm actually doing small movements. After I surpass then "wait distance" it functions properly.

https://streamable.com/4wqvd

Interesting find, though it didn't affect my daily use cases at all. I'm very sure this is software because the hardware functions normally after that distance is traveled.
[Huawei P20 Pro Questions & Answers] AndiThebassman:
If you try editing a picture and you paint a line on the screen it works perfectly well. So definitely not a hardware issue
[Huawei P20 Pro Questions & Answers] otonieru:
This effin problem was there in various 8.1 phone. Heck, even my pixel had similar problem until the magisk module fixing it was released.

Too bad the module ain't work on this phone since it causing bootloop
[Huawei P20 Pro Questions & Answers] kkrriiss:
I actually think he's right about the Oreo problem, cause I experienced this with my Pixel 2 XL too =(.
[Huawei P20 Pro Questions & Answers] varignet:
same behaviour as shown in the video on my honor view 10.

I'm returning it, it's a lovely phone, but I think I'll just wait for the new op6.
[Huawei P20 Pro Questions & Answers] chrisrk45:
I have the same problem on my P20 Pro CTL-L04, playing PUBG!

but i became developer and i change the scale of animation and other settings to 0.5x and i see just a little less lag :good:

i hope everythings going better on a future update from EMUI, i have 8.1.0.102 (C69) in MEXICO!!!
[Huawei P20 Pro Questions & Answers] donatinho:
Talking about Camera AI, it's false only option is to use RAW. Even from normal foto mode, just go to options, and disable Master AI. After that you will use it as a normal smartphone, with every automatic setting working, just AI disabled.
[Huawei P20 Pro Questions & Answers] Mixy:
Except it's not. Master AI is turned off, their software still does it's ****ty magic
[Huawei P20 Pro Questions & Answers] donatinho:
Not on mine

Which version are you running? As a simple test, do you still get beauty filter on the selfie camera?
[Huawei P20 Pro Questions & Answers] kungcoopa:
U clearly have no idea what the screen lag we’re talking about is. To show it on video you have to make a video of your finger slowly moving up and down on the screen.
[Huawei P20 Pro Questions & Answers] Jonathan-H:
This is fixed on .110. I had this, had to move finger 3 to 4 mm before the screen would start to scroll. Now after todays update it is perfect and starts to scroll as soon as you touch the screen.
[Huawei P20 Pro Questions & Answers] kungcoopa:
Sounds great! Can anyone else confirm this?
[Huawei P20 Pro Questions & Answers] robot1000:
Yep - Tried on multi-touch app and it shows it's picking up the slightest of movements.
[Huawei P20 Pro Questions & Answers] spindowski:
Yep can confirm as well on new .120 update.
[Huawei P20 Pro Questions & Answers] karam94:
CLT-L29, still stuck on 8.1.0.102 (C782) in the UK :(

The lag isn't the end of the world for me, but very disappointing coming from an iPhone.

I don't play PUBG that much, but it's clear it's a software issue since the small movements show up when you enable the tracking purple thing in dev mode yet it's almost like the software has a "minimum movement required" to actually move.

Over the moon to hear it's been addressed on .120... need Huawei to give me the update first... can't believe I'm still stuck on .102 lol
[Huawei P20 Pro Questions & Answers] robot1000:
Have you tried forcing the update to 110 using https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder
[Huawei P20 Pro Questions & Answers] Neo_Sk8eR:
Can confirm here too :)
[Huawei P20 Pro Questions & Answers] Abolo6:
I hope we will also see an update for the Honor 9 but maybe this device is already too "old".
[Huawei P20 Pro Questions & Answers] Paz9:
Coming from a oneplus5T the P20 pro is noticeably leggier slower, not that its a slow device, the 5T did everything effortlessly

Here's hoping the oneplus 6 has a camera equal to or better than the p20 pro

---------- Post added at 06:24 PM ---------- Previous post was at 06:22 PM ----------

What module? I can try and investigate
[Huawei P20 Pro Questions & Answers] karam94:
Nope. I've been trying to be patient and waiting for the actual update to come through rather than taking any risks using Firmware Finder.

I have downloaded it though and it suggests .110 should be the latest release for my IMEI...

I'm wondering if the reason I am told there is no update is because .120 is the latest and so the .110 "IMEI batches" restart from scratch?

If so, poor system. Should still let me update to .110... surely there has to be a reason for this other than to reduce load on their servers? lol
[Huawei P20 Pro Questions & Answers] N1nj4s:
Just updated to 120 from 107. I can confirm this update resolved the issue at least for me.
[Huawei P20 Pro Questions & Answers] NeverNice:
why you could not confirm it earlier? ... I gave mine back already
[Huawei P20 Pro Questions & Answers] chrisrk45:
In mexico i still in 102, Waiting for the update to arrive soon, I really like playing the PUBG, but it is unplayable with this touchscreen problem...
