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

Seems like there's a noticeable latency with the display when it comes to register touch input. I read about the P20 Pro also having this problem.
I often use apps like "Beat Maker GO", which just can't be used anymore because of the delay that comes with the display.
Before that I was using a Nextbit Robin with a custom firmware (OmniRom) and the touchscreen responsiveness was on point.
Are there other people with this problem? Is Huawei aware of this?

I did not notice any lag on my unit.
Blue P20 EU dual SIM.
Been playing Tap Tap Reborn 2 with no issues.
Contact Huawei and your seller ASAP imo, I'm sure Huawei is aware of most of these issues.

Advice on P20 vs Pixel 2 cameras

Hello,
Most of the reviews are very focused on P20 Pro while P20 isn't that popular. In my country I can get the P20 a bit cheaper than a Pixel2 and probably prices will drop after P30 release.
Aafter looking at the P20 it has some advantages:
+ screen without Pulse With Modulation
+ fingerprint scanner on the front can help with unlocking the phone more easily when on my desk
+ battery seems pretty good
+ fingerprint scanner gestures so that the nav bar can be removed. Not sure how good it works in this way.
As for downsides:
- notch which I find annoying on phones can be reasonably disabled via software
- camera bump
- back glass easy to break and slippery
Huawei seems to be doing pretty good in the software updates department also. I do not game intensive games, I do not root or use custom roms.
Pixel 2 has the advantage of another almost 2 years of updates, metallic back, stereo speakers. But also disadvantages as old design, amoled with PWM, limited customization options in Software.
My main concern is how are the cameras of P20 vs Pixel 2? I will use the phone to take pictures and I want a good camera.
Any drawbacks of P20?
Thank you very much for your time.
Hello!
Take the P20. Here a few reasons.
Huawei promised to roll out 2 Major-Android-Updates. So Android Q will come to us.
The P20 has 2 Lenses (color/monochrom). So you can shot real monochrom pictures without any filters.
Sometimes the Master-AI is helpfull, sometimes not. But you can disable it with 2 taps.
There's some kind of instant on-screen-translator within the Camera-App and it works a lot better than googles on-screen-translator. It can also read QR-Codes and recognize different objects thanks to AI.
You can record SloMo-Vids with 960 fps, which is quite funny.
The Pro-Mode is incredible. You can control everything.
The P20 UI is highly customizeable. Thousands of Themes are available and you can create one on your own.
And here some of my Pictures.
I hope my opinion is helpful.
Thank you very much for your time and detailed answer. I was not really aware of the 960 fps recording but reading more about it (https://forum.xda-developers.com/huawei-p20-pro/help/truth-960-fps-slow-mo-t3789574) seems not that good.
Thank you again.

NBA: Realme 5 Pro or Redmi Note 8 Pro

Hi all,
I am thinking of buying a new Smartphone. In my country Realme 5 Pro 8GB/128GB and Redmi Note 8 Pro 6GB/128GB are similarly priced. I am really really confused between these two.
Which one should I pick?
You expert opinions are required.
Thanks in advance.
No-one yet?
I am more inclined towards Realme 5 Pro basically due to SD712, Sony Camera Sensor and 8GB Ram Variant.
Currently I am using Realme 3. I don't like Color OS and Camera App. But I have heard that Realme will be providing its own UI with stock like experience. Is it true? And is there any changes in Stock Camera App expected?
Well that's a tough decision. I just bought RM5P 8/128 GB. Have used Xiaomi for about 4+ years and was happy with performance and software. Xiaomi provides lot of power packed software feature and highly customizable UI. But having used for more than 4 years, I was bored with MIUI, so I thought of switching to something relatable.
After I got my hands on RM5P, I was disappointed with the software and less customizable UI, but man, I have no words for the performance and camera. I am glad I made a good decision switching to this as this one has power packed hardware features which no brand has given in this price range. Hopefully, the software will be improved progressively.
My advice: If you have never used Xiaomi, go for Redmi Note 8 pro. Else go for RM5P. You will be happy with both.
Currently using Realme 5 pro(6GB Variant). To be honest, Redmi Note 8 pro looks more premium with its glass back. Realme 5 pro does look somewhat premium but nowhere close to Redmi Note 8 pro. The Redmi has a faster CPU and GPU but I heard some issues with overheating( and I don't have faith in Mediatek). In the realme, I have not encountered any overheatiing isues till now. But playing PUBG for longer periods makes the phone a little bit warm which is completely normal. If you want a phone for heavy gaming go with POCO F1, this phone is way better in terms of performance but looks kinda outdated( I regret not buying it). If you want a premium feeling device go for Redmi Note 8 Pro & if you want a overall better device go for Realme 5 pro.
Thanks, and what about Camera performance?

I Have used Redmi Note 4 a very long time ago and I don't really hate MIUI that much. Color Os is totally on other level of crap.

Realme 5 pro has very capable cameras but the 48MP images doesn't look that sharp. Normal 12MP is better( I think).
Don't know about the note!!

I just bought Realme 5 Pro 4/128 variant after (and still) owning Realme 3 Pro 6/128. I have considered Redmi Note 8 Pro before buying, but at the end I chose Realme. Here is why:
- Photography is the most important factor for me, thus I was looking for a phone with Qualcomm SOC because it will have Gcam mod for it. But then I saw on youtube lately that gcam mod also has been made available for RN8 Pro with mediatek chipset, but unfortunately the stock camera is still better than the Gcam on that phone. In case you don't know, the right Gcam variant with the right settings on Realme 3/5 Pro is amazing. I have compared it with my friend's Galaxy S9 and S10 and it put them both to shame when you examine the detail side by side at 1:1 zoom. Gcam on realme even manage to equal or beat my mirrorless M4/3 panasonic gx85!
- I read that RN8 Pro has touchscreen issues that still has not been fixed till now.
For me, ColorOS is ok. It has very aggressive RAM / battery management that often closing running apps eventhough there is still plenty of available RAM. So I just turned off the power saving feature (called 'Smart Power Saver') and use 'custom power saver' that allows you to set background running permission individually for each of your apps that you know shouldn't be close automatically like gps sport tracking app in my case. In app management setting screen you can also specify that certain apps are allowed to do auto start. You can also locked the app in the recent app screen so that it won't be closed. Unfortunately that setting is not persistent and only work until the next restart.
I'd never prefer an mtk powered device over an SD one. Just look at rm8p xda development forum and here. Words are quite unnecessary.

I have used gcam with my LG G6 and the results very stunning. But on my Realme 3 gcam is not as good.
Thank you very much for a detailed reply. I also feel the same.
I have also made the similar thread in RN8 pro forum and no-one has yet replied ?.

Well, as you wish but rooting and custom stuff can noticeably lengthen your device's life span and raise performance, lower battery consumption. Idk why would anyone willingly not want these but it's up to you. Even if you don't count these a SD powered device is mostly better choice for base lifespan of chipset is longer and features to add later are most of time more available for SD devices rather than mtk.

I have also come to know that Xiaomi Has released Source Code or something like that which will be very helpful for development. Actually I read it on XDA review. They also wrote that they have shipped few RN8 Pro to devs for active development. Although Development Section of RN8 Pro seems very inactive as compared to Realme 5 Pro section.
Most Probably anyone buying phone is this range will be buying a new phone after one year so Longer Life Span of phone is just not required if it can live for one year with its performance intact (Which I have doubt about due to mediatek).
Most of the people will never use Rooting and stuff on their phones even if the stuff is available for their phones (I Guess). But it is always nice to have support for your device. It is a plus but not a negative in my view.

Absolutely agree. Although even with released source code and free gift devices to developers indeed xda seems way more inactive if we compare redmi note 8 pro and realme 5 pro. I'm absolutely glad I bought this device instead of rm8p especially as you said custom stuff support and help. Probably mtk devices aren't the favorite of developers either so rm5p getting faster development with delayed source code reveal and even without gift devices to devs.

Yes there is in Indonesia.
This version MGC_6.1.021_MI8_V2e.apk
In addition to the instruction there to set the saturation, I activate HDR+ enhanched mode which gives much better result in settings > general - advanced > HDR+ control = on and then set to hdr+ enhanced in the camera main screen.

Poco X2 ghost touch problem.

I am facing ghost touch issue in poco X2 and the problem is getting worse day by day! Anyone who faced similar problem in X2?
I have touch issues also; the screen registers touches when my fingers are near the screen; it worse for me when charging. If you are in India and bought it from Flipkart; I would ask that you raise it with them as soon as possible. I have asked for a replacement on june 17 and their response is abysmal.
Same ghost touch issue here...

Yes, I also have been facing it since last 2-3 weeks.
I think it might be due to some update in some software, mostly keyboard. I am using Microsoft SwiftKey as keyboard. What about you?
Here we are. Tianma lcd panel? Same problems with poco f1, note 8, note 8 pro. At least about this phones I've been reading extensively. And it's hardware not software problem. I wanted to buy Poco x2 but this thing is obviously deal-breaker. Pathetic
I have been using it for 2 weeks and never had any issue.

I'm exactly in the same boat as you with my MI A2 touch issues. I've been researching this too for a while now and looks like I'd have to switch to either Oneplus or Realme. Poco X2 was really interesting but deep down i knew.

Doesn't matter, even the displays from Huaxing in Redmi Note 9 Pro has bleeding and retention issues, so goodbye Xiaomi, i guess.
It's a hardware issue in my case (India)
I bought a brand new Poco X2 on 11th July and got it delivered on 13th July. I have been using Xiaomi phones for the last 2 years so the learning curve with MIUI wasn't much for me, the only thing I needed to get accustomed to was the form factor.
From the very first day, the keyboard used to double tap. While playing PUBG, it would auto press some buttons (reload, backpack etc.). Also, the gestures weren't particularly great.
Initially, I thought it happened because I wasn't used to it, but after 10 days the problem persisted. That's when I decided to do a deep dive. I downloaded several multi-touch test apps, and indeed, it showed the problem of ghost touching. Even while touching the screen once, the max. events would show 2.
On top of this, I faced a very poor screen flickering issue.
I submitted my phone to the service centre on 28th July. They said even though they have not received any X2 with such complaints, there indeed seems to be something abnormal with my phone. It could either be the display or the motherboard or the PCB or the worst - a combination of 2 and 3. So it's either a repair or a replacement at this point. They have asked for 6-7 days, so let's see.
But if you are using the device and facing such issues, don't hesitate to raise your voice.
If you're planning to buy the device, RUN AS FAR AS YOU CAN FROM THIS ONE. Don't buy this.

The situation with Poco X2 in compare to other Xiaomi phones is still much better. Poco X2 at least doesn't have miserable tianma panel. Problems will occur but majority of don't get any issues

Does Xiaomi Mi 10 Pro has the same screen problems like OnePlus 8 Pro?

Hello,
I have OnePlus 8 Pro and Oppo Find X2 Pro.
Under 5% screen brightness OnePlus has huge black crush.
They fixed it with beta DC patch, which makes colour accuracy hitting the floor.
Oppo has very small black crush on minimal brightness level.
Both Oppo and OnePlus have the same screen model (just differently calibrated - OnePlus has extremly vivid calibration just like S20 and Oppo has very good natural colour calibration) - but same problem:
between 5-10% screen brightness there is a step which is making everything tinted green.
You slide brightness from 1% to 10% and you will have colours like: ok ok GREEEEEEEN ok ok ok.
I won't accept 1k€ phone having such bad screen, so I am thinking about trying flagship Xiaomi,
can you go into complete dark room and slide brightness from 1% to 10 and tell me if the colours stays the same?
I also have S20 Ultra and iPhone 11 Pro Max - their screens are just perfect (iPhone has much warmer screen, very pleasing to human eye), but I don't like iOS and Samsung has pure garbage Exynos CPU in EU.
Interested as well
Any kind soul to check as per OP request?
Sent from my OnePlus8Pro using XDA Labs
I've tried it. Miu12 xiaomi.eu latest stable. No issues, screen colors remain very consistent. Let me also note that this phone/rom combination has a really good auto-brightness implementation. I've had numerous phones, this is the first one i never need to manually fiddle with brightness.
My only complaint about this phone (or miui) is its out of the box aggressive memory handling. Need to tune many settings of apps to not miss notifications.

Thank you for checking!
In the meantime I also discovered a fix for my Oppo screen problems -
there is an option called 'low brightness flicker-free eye comfort' and after turning it on the screen is perfect.
It is basically the same thing as OnePlus did (PWM/DC patch), but this one actually works,
while on OnePlus it fixes one thing and brake two others.
Long story short I'll be staying with find x2 pro, because of 12GB DDR5, 512GB UFS3 and
well baked ROM with good RAM management.
Have a nice day.
PS. Auto-brightness is indeed bad on Oppo, Samsung and OnePlus and it's great only on iPhone.
Another thing I'm missing with Oppo is wireless charging, but I'm OK with those issues.

Question [CLOSED] Serious Poco x4 pro problems even after latest update ?

I saw this video focusing on various Poco X4 Pro problems including problems with display, camera, fingerprint scanner, microphone and lagging problem on the phone.
<Moderator Edit>: Self-promoting video link deleted.
Can someone explain the Poco X4 Pro Display problem in the video where we can see backlight bleeding on black images under low brightness in dark rooms, Poco X4 Pro camera problem and microphone problem where the camera lags when choosing between various camera modes and how the microphone problem is present whereby the quality of audio recorded by video camera is very poor.
The only problem that I've experienced so far is the Poco x4 pro lagging problem and Poco x4 pro heating problem is also present when playing games like Call Of Duty or PUBG.
I want to check my phone for these problems and get a refund before it is too late if I'm having these.
So my question is where the problems mentioned in the video can be solved by software updates or not ?
Also are these problems present on all Poco X4 Pro phones ?
Sounds like you're having to thoroughly test a phone in strange conditions to look for a problem that doesn't effect you... Can't say I've got any issues with my phone. Fast enough and fluid - use my phone alot at night time and haven't noticed screen bleeding on a pure black image etc but I've not gone out of the way to look either. No lags swapping between camera modes, not a phone gamer so don't care about overheating either.

The only problem that I've experienced so far is the Poco x4 pro lagging problem and Poco x4 pro heating problem is also present when playing games like Call Of Duty or PUBG.
I want to check my phone for these problems and get a refund before it is too late if I'm having these.
So my question is where the problems mentioned in the video can be solved by software updates or not ?
Also are these problems present on all Poco X4 Pro phones ?

Display Issues - Yes indeed black is not true black under the circumstances mentioned in the video however this is because of just Miui stuff that enhances colors and tries to make stuff look better haven't found it on the (unofficial) Pixel Experience Plus rom
Camera Lag - yes have noticed camera lags and stutters and overall being not so smooth of an experience but i recommend you to use a Gcam as it has none of those problems and even lets you record videos at 1080p 60fps unlike Miui camera
Quality of audio recorded - Okay seriously? That was just dumb his phone might be 2 years old but the price is still more than twice than that of Poco X4 Pro so obviously it would be ahead
Gaming - Unfortunately this is not a gaming device they call it the "All around ace" but i don't see where is the all around ace in the phone?
The branding of this phone is so bad...
People will think since Poco X3 Pro was a beast of a gaming device the X4 Pro would be even better but no not in the slightest
Refund - if you want to you can... there really are better devices for this price segment
remember a good processor can make a lot of stuff good like camera quality, audio processing etc
Can these issues be fixed with a software update
Cough Poco X2, X3, F2 cameras just dying after a software update with no fix even after so long
Cough Cough Poco X3 Pro hard bricking due to system updates and no fix even after so long
Don't you worry mate Miui will come to your rescue to fix every problem you have!
Is it worth getting the Poco X4 Pro?

Depends really
If you're living in the Asian countries there's several manufacturers providing you a better buck for your money e.g Iqoo
but if you wanna definitely buy a Xiaomi product then going for the Mi 11X which costs just a tiny bit more than the X4 Pro
Even the 6gb ram variant is far better due to the snapdragon 870 being a beast
In my opinion go for any device that has a snapdragon 8 series processor or the 778G
A processor matters a lot in a device
A good processor can accomplish several tasks with ease
E.g camera quality will be better and you'll most likely have 4k recording
Audio processing better
Rendering is better
Everything will look better since a better GPU
Overall better performance
But if you've already bought the device and thinking if it was worth your buck
imo not really... It lacks several features devices have in this price range even though people coping that this is a great deal
Never trust in the 5g gimmicks people will keep on telling u that the snap 480 5g or the 695 5g processors are amazing but that is a heck of a lie those are old processors overclocked but still way behind the league

Thank you for this detailed information, I was still planning to get this phone but as you said iQoo new phones are good too for this price range and Mi 11X is expensive for my budget Also for me display to matters because I hate the LCD in budget phones, AMOLED is good for eyes! I'm going to see the best budget phone with good specs and with snapdragon 8 processors as you said.

No problem mate!
I recommend you to stay away from Poco in general though
Their specifications might look very appealing but almost every single phone of theirs has had a major flaw without any explanation provided by Poco
E.g X2, X3, F2 cameras just dying after a system update no fix even after almost 2-3 years
Poco X3 Pro which I'd say is the most appealing phone ever made...
Hard bricking after system update due to low end PMIC's
No fix after almost 2 years
side note: i was a Poco X3 Pro user until about 4-5 months ago when my Poco X3 Pro died after getting Miui 13 update
Luckily still 2 months of warranty was still left but it took almost 2 months to get a replacement and i got the X4 Pro
They were gonna give me the Redmi Note 9 which was absolutely disgusting compared to the X3 Pro so after a few fights here and there and paying about 50$ i got the X4 Pro...

The dark mode problem is in hardware or software? Because, in recovery mode, fastboot mode and on first boot poco logo, the display shows pure original black... But when it starts up on miui logo, display's upper side bocomes lcd black not amoled black.. so, what the problem basically is? On software or hardware?
@Mrajhacker0 I've closed this thread. Check the PM I've sent you.
