Getting To The Root of The Scroll Lag

Okay, I've done some observations on the scroll lag issues and here's what I know.
- It persists on 8.1 ROMs too
- It mostly affects custom ROMs
- Switching kernels does not fix it
- Max CPU and GPU does not fix it (even OC)
Here's my suspected causes:
- Our touchscreen driver is bad
- Our touchscreen panel is bad
- Included screen protector is bad (anyone have scroll lag without it?)
Tell me if you notice this too, but when I scroll with my finger in the top right edge, I get almost 0 lag when scrolling. Is it possible its the display sensitivity that isn't stable? Do you feel this too? Maybe its other areas of the screen too.
Please share your ideas and thoughts. We really want to fix this issue as the phone would be so amazing if it didn't lag EVERYWHERE.

I think it's a combination of both : bad touchscreen and bad driver's as it seems to affect both stock, Caf and Los . I did a test with an old Samsung note 4 an iPhone 5s and a Huawei p20 Pro and it seems that there are certain "gaps" in the panel that when in usage register touches with a certain latency . This and also the sub par refresh rate. Even the old iPhone/note had better touch accuracy under heavy load.
I guess this is the price you pay for a 150 euro phone. Some corner's will be cut.

I can update the drivers from another kernel. Do you get hot spots on the A1 that you can notice (for me top right very edge)?

Honestly, I've replaced my tianma display in service centre for screen retention issue, i got ilitek ones then the display is super smooth n scrolling is smooth. it's the problem withth your display ",faulty display"

Do you get lag when scrolling at the edge of the screen? For me its smooth on the very edges.

Sorry for late reply. Not really hot spots or you could call them hot spots but the are in a H pattern across the display. Also touch accuracy is abysmal.
Now I've installed Flyme OS the problem still persists that and the screen becoming tottaly unresponsive. But the proximity sensor bug it's gone, so altleast that is a good thing.
If they don't fix altleast some of the bugs in 8.1 I'm goona smash this crap phone into a wall

I think it's a bad driver or a bad digitizer. Imma try to fix it soon

You can replicate this lag 100% of the times with this "method", at least for me. Use your thumb with as much flesh touching the screen and then slowly drag your finger. You can notice the scroll lag in every direction.

Same with me, firstly, I thought it is bug of xiaomi rom, may be this will be fix with custom kernel and custom rom. But when custom rom came to mia1, try so many rom but laggy still there, really disapointed.
It is awkward that seem mia1 is the only xiaomi face with this issue. Redmi 5a - lowest price phone of Xiaomi is fine and MI5x same spec with mia1 doesn't have any complain about laggy scroll.

I discovered that if you have two fingers on the screen there's no lag. So use one finger and hold it, then start scrolling with your other thumb. 0 lag. It's gotta be a driver thing. I've been working on micro optimizing it but its gotta be something with the scanning frequency when there's only one finger. But frequency is a firmware thing and I dont think we can gen a firmware blob without a manufacturer tool. It's also possible it's a voltage thing (which I can set in the driver). I'll keep working on it but I think its definitely fixable.

Hey guys i dont know this problem, just bought one, does it easily notice?, how can i check it?

Did you start having the issue when you first got the phone or after you first flashed a custom ROM? Maybe its a persist thing.

The phone lags a lot (ch rom at least). Switching, opening tabs, etc). Overall animations stutter a lot. I hope some developers find it in their hearts to help our poor souls and release a rom with all the xiaomi junk removed.

Are you using global ROM or EU?

I've the 3/32GB global/EU version. It's the worst new phone I've bought ever when it comes to performance. It's just a week old and I've installed the apps that I had on the Note 5 before. Everything is more laggy than with my old 5. I'm really frustrated, because it seems to work fine for others.

Xioami.eu miui rom? Not the model version itself. If u are not familiar with it and I feel like many aren't, Eu rom is like a debloated stock rom and less buggy across all xiaomi phones compared to the stock global/China rom it ships with. U should also use 3rd party apps like fluid navigation gesture on the playstore for no stutter instead of miui's full screen gesture from settings. A lot of xiaomi phones can be a way better experience this way even on miui until custom roms are out. Global version for more bands+EU rom instead of global/China+apps like fluid navigation, Google cam, dolby/viper etc. Let me know if it helps
https://xiaomi.eu/community/forums/miui-rom-releases.103/
Hardware and cost is good but chinese software is probably the worst part about buying a phone that has trouble getting bootloader unlocked. Xiaomi and oneplus seem to have an advantage with that over most of the other companies even though xiaomi makes u wait forever at least it's still possible

Thanks for all the tips man! Sure it helps! I can't wait till Friday for the 360 hours of waiting to be up. I will right away install EU rom, and as you said, it already is a much more fluid experience, but even after that I will install the fluid navigation gesture as you suggested, and also a different launcher.
One thing though, I am crazy about better sound and with stock MIUI there is no way to 'tweak' Bluetooth sound (EQ, better, bass, control base frequency, etc). I used to have a Note 8 I gave to my uncle which had a crazy amount of tweaks that made me much more satisfied with Bluetooth sound even though we all know it is just 'average sound'.
Do you know which vyper4android mod works best for the redmi note 7? Can I still something similar? have you tried any? Or is it just a universal one?

what's your display model?? redmi note 7 Touch latency issue

Hello everyone. Can you guys maybe help to check what the model of your screen is? Just enter the cit test by clicking kernel version multiple times and click software version, the first option. And under LCM info, there should be the display type.
Want to further investigate the touch latency problem with this information.
Thanks.

This is my version. I have Global stable Rom PFGMIXM, I read on Mi community,that people complaining about this,but I dont have problem.
Factory ID is only different between your and my information..
Maybe also ROM that you use have some bug.
I am using 10.3.5.0 almost a month..I get this update on 19 April. Whit this update I don't have problem with touch and especially at the end of screen side. I use temper glass 0.33 ,maybe thats change my screen latency.

Wow never saw that. Are you using the global version

Here's mine...touch isn't bad.
Not as fast/instantly responsive as my wife's iPhone 6s of course but don't have the complaints others mention on the forums.
I will say that the paid app touch screen repair has also helped improve the responsiveness a tiny bit.

I have Boe too, global version

global 10.3.10 stable

I also have this touch latency issue. I have the same model as yours. Hope they fix the issue because it can be very annoying sometimes.

I also have that tianma display, but i don't have any kind of display lag.
I have the EU version with Miui 10.3.6.0.

I have the same display too (tianma) but I do not have any problems that I am aware of. If anything changes I will post.

BOE panel for me. Altough it isn't THAT bad, I can see the letters getting slightly thinner when scrolling through text, but also when the display brightness is cranked up to maximum, the notification/quick toggles panel has a really ugly colour to it, like someone would put too much contrast onto it. At night, when I have reading mode enabled & have the slider at maximum, I notice a lot of blurring of text, to the point where it becomes somewhat annoying

That's a software feature, albeit a weird one, of MIUI. I had the same issue with a Tianma panel on MIUI. Switch to a custom ROM if it bothers you.

Hey everyone thanks for sharing your screen model. As of what I saw, the majority of you guys seem to have the tianma screen model, and some of you faced the same problem as I do.
As of one person said, we should try the touch calibration app. However, for me, it didn't work, it showed no signs of improvements in touch latency.
I also recently updated the software version to 10.3.10, but the problem still persisted in this version.
Also, a new problem seem to appear, scrolling through screens now seem to be more laggy than before.
What do you guys think? How is the new version working for you guys?

My formula....take it with a grain of salt...
No root needed...
1. Activate developer options
Use ADB to use custom animations
Set to:
1.23
0.11
0.67
2. Download the paid version of both Touch Screen calibration app and the other one Touch Screen Repair.
Follow both apps instructions...
Reboot after running calibration/repair for each app.
3. If you want to take things further, download (via Google search) the APK SGS Touch Screen booster.
Set your settings to what you see my attachment.
You should absolutely see some difference vs stock touch screen latency performance especially if you do all 3.
Do you have to do all 3, absolutely not. But if you're curious...and have some time to kill research each app, how it works etc and see what happens.
I do no own any of the mentioned apps or benefit financially from recommending people check them out.
Want to make sure I point that out as well.
Will it make your screen feel exactly as a newer model iPhone level response...of course not. BUT it will absolutely improve how your screen responds and feels.

Did another test tonight.
Changed my Window Animation to 0.70 this time. Only other change was SGS Touch Screen app motion filter set to 0.
My touch latency performance improved again and typing is a little more accurate. Getting even closer to our iPhone 6s' screen which is fantastic!
Try these settings out and share your experience

Mi 9T very laggy

My Mi 9T is lagging since the day I've bought a week ago.
It lags in everywhere, since basic use up to heavy.
Screen trasition lags, even YouTube playback lags too.
I'm on Miui global stable, latest version and I've reseted it twice but the lag remains.
YouTube video: https://youtu.be/-eGIXvn-_ms
What else can I do to solve this problem?
Thanks in advance.

It's very likely that you got a defective unit, mine doesn't act like that at all. I don't know too much about this topic, but maybe a custom ROM would help?

Try to return it first and claim your warranty. I think it probably a defective unit, like worm_guard mentioned.
Mine doesn't have any lagging problems like that. Also, I used SwiftKey instead of Gboard.

You could reflash global ROM with MiFlash tool: it's official so no warranty problem

Scrolling issue/lag

Is anybody else experiencing scrolling issues on their OnePlus 8 Pro?
I have noticed what feels like the touch input not being recognised so when scrolling up or down a page it just stops responding. At first I thought this was palm rejection related but it is not.
It is likely software but I am worried it could be hardware. Anybody else?

Yes, theres a few threads on here and in the OP community about it. No idea whether it's soft or hardware [emoji1745]
Sent from my IN2023 using Tapatalk

Sorry I did search on scrolling and got no results. I'll take a look. I purchased mine from Amazon so if there is any sense of it being hardware I'd probably return it while I still can.

Yes I have had this happen almost everyday I put to sleep and put back on.. loving the device for most part but that and then wifi calling not working ugh.

Ditto on the lack of response. Thought it was Palm rejection or even one of the Facebook chat bubbles overlaid on the screen while in chrome causing overlay issues.

Factory reset should fix

Are you on QHD or FHD, I switched to QHD and then back to FHD I had this issue. Rebooted whilst still on FHD and it's fine..
There is no benefit to be to use QHD, it's a 6" screen not 60"
Switch to FHD then reboot and test, should be fine.

Had this issue myself (chrome and youtube) Im using FHD only. Reboot fixed it tho

I'm getting this while using Opera browser and using certain apps, it gets really 'sticky' scrolling if I leave the app it's fine but then comes back.
Restart works for awhile, do guys suggest a factory reset?

@wilpang I'm experiencing similar behavior. I suspect the latest update of webview to have a negative impact on this behavior. It seems generally an issue with HTML5 apps but I may be mistaken.

You compare resolutions of devices as if you sit the same distance awayfrom a phone and a television. I guess you can do what you want but the higher resolution in phones is because you are much closer. So duh, anybody can tell a resolution difference when you're that close.

Wtf are you on about???? It's a six inch screen. You cannot tell the difference between FHD and QHD, don't talk crap by saying you can.
Even if it's marginaly sharper to the eye, it does not merit the loss in battery life.
There TV analogy has nothing to do with how far your are from it, you said that not me.
Jesus.

The current update for the One Plus 8 Pro's changelog has stated to improve the performance by apps dropping down from 120Hz to 75Hz. Is it true for everyone with the latest update? I think it should force stay at 120Hz for a overall excellent experience.
