Mi 9T very laggy - Redmi K20 / Xiaomi Mi 9T Questions & Answers

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?

honestly it's probably a defective unit. mine is extremely smooth and fast. i never experience any lag or anything. coming from a poco f1, i haven't noticed and difference in smoothness in my day-to-day usage

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

Worse than I bought it in China, I hope the seller helps me with this situation.
Earlier the phone crashed and everything went black so I forced reboot and it slowed down after that

PUBG Mobile on essential

Has anyone else here played this game on the essential phone? I have a couple of strange glitches. I initially thought they were associated to my original faulty device, but after receiving my warranty replacement that is not faulty the same issues still persist on PUBG Mobile. So I am assuming it's something with this phone in general.
First glitch is some artifacting during the loading screen on the notch end of the phone. I am assuming this is because of the screen resizing to accommodate for the notch. It seems like it starts to attempt to resize the screen a few times in a row every once in a while resulting in what looks like some screen glitching. I've noticed this in other apps while using them too like chrome and OfferUp. Looks like every once in a while the app suddenly attempts to resize back to full screen mode for a split second, then immediately shrinks back down again to cut out the notch area.
Other issue is while using both fingers on the screen at the same time. Moving while aiming for instance it will spin my character around a little bit.
Doesn't display any of this behavior on any other phones I've ever had. I already contacted the publisher of the game but Wondering if anyone else has these issues and knows a workaround.

Strange, I don't at all. I full wiped and flashed from fastboot though. Did you ota?
So you still have the graphical glitches?
How do I get P?
Also is it possible to force games and other apps to utilize the full screen pace around the notch? As much as I don't like apple I do notice in YouTube videos that it does fully utilize the notch area on the iPhone X.
Alright nevermind found the settings in developer options from YouTube video to force all apps to use the notch area.

I flashed the ota through adb, did not factory reset though. I think the issue is involving the multi touch that was broken in and 8.1, and I don't think Google has fixed the issue

Like I said before, I flashed the full fastboot file, not just the ota. It is fixed completely. You could try that.
Yes! God, I thought I was the only one with the multi touch issue..but I'm too lazy and stupid to get P so I suppose I'm out of luck.
There's a fix for the multi touch glitch bug. It's a magisk module called "Pixel 8.1 multi-touch fix".
Let me warn you, DO NOT install it if you are on the stock essential ROM, because it will fail to boot. It is only safe on AOSP based ROMs. I can only vouch for myself that it works flawlessly with lineage. If you are on stock ROM you'll have to wait until essential releases a fix.
I just read up on it a little. Apparently it's an issue with all phones running 8.1.0 Oreo witch I did not know. My original essential PH1 was faulty, kept crashing and rebooting so I thought this was part of the faulty device.
Looks like they plan to release a fix in June security update.

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.

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?

low touch latency on redmi note 7

I wonder do anyone else face this problem?
When i scroll through things, it seem to lag behind a bit. I also tried to compare it with other phones and this phone seem to have a much higher touch latency than the others.
Anyone facing similar issues on this phone?
I have the EEA version of the phone and nope, no troubles at all and the touch is so responsive and smooth ?
The same problems here, Global version.
same here, global variant RN7

Same problem. Very frustrating. RN 7 global version, 4/64gb
Yes, me too. Especially annoying when typing - keyboard is very laggy and driving me crazy.
I had the same feeling on my old crappy Mi A2 Lite. It was much better after switching to a custom Kernel (Butterfly Kernel).
Now I have the 128GB Global RN7 and touch responsiveness feels just fine. No problems at all.

What miui version are you on?
So far, my Global Version 3 day old RN7 on 10.3.5 doesn't seem to have bad touch latency.
Was nervous about that considering this phone is my first Xiaomi device.
So far so good.
Have you all tried using the old Touch Screen Booster app? Not sure if the apk is still on the Play store.
Try the app if you can. It fixes a lot of touch sensitive issues without root.
Won't make your phones touch response iPhone level smooth but it will fix whatever ailments you're having
I have the RN7 Global and not facing any of the problems people comment about the phone... No lags, no video rec problems, no battery drain, none of all...
My guess: We would face palm us hard if we knew what apps some people install...

Man... Sorry to hear.
Is the app the one that's got the neon green color icon?
If that doesn't work your digitizer could be defective or the update to 10.3.5 could have altered how your touch input functions.
If that's the case, you could also try both touch screen repair and touch screen calibration apps.
Unlike SGS, they're both paid apps in the app store that should help improve your touch response without root.
I used both on my honor 8 and can vouch they improve touch latency response on our phones

I also tried those and they say my original latency is around 47 ms, which is quite okay by this number, but it just doesn't really feel right. Everytime i scroll something, it just seem to lag behind quite a bit unlike other phones. Just tapping on things seems really fine though, no delay for that. And i also went to the store today and tested the demo there. I found out that the demo also have a similar problem. Can i conclude that this problem is not a defect for my phone?

Not sure.
1. Are you also on MIUI ver 10.3.5?
2. Was your touch response ever working fine beforehand and the latest update broke it?
3. What other phones are you comparing the RN7's touch response with?
For me I'll answer:
1. Yes... But I find then touch response the same vs the prior version of MIUI that was on my phone right before it updated to 10.3.5
2. See my response to #1
3. I'm comparing the touch to:
IPhone 6s(which is still the fastest touch response to date), Honor 8 which was great but with the apps above, touch latency/response improved and Galaxy S9+.
I find Redmi Note 7 is slower than our iPhone 6S, close to my Honor 8 with the apps mentioned in the previous post and on par with the S9+ I played with in store.
I found that bizzare since AMOLED screens typically have faster touch response vs IPS/LCD etc.
What are you guys seeing?

A little disappointed about the performance

Hi there,
I am now using my RN7 (3/32) for about a week and I am really disappointed about the perfomance. I had a P9Lite and a Moto Z Play before, both phones did start Apps way faster than the RN7. I also have little lags when scrolling e.g. in Nova launcher or the system setting. Is this normal that a 2 year old phone with half as much antutu score as the RN7 is faster? Or do I have to change anything?
Phone is not rooted, all on stock and I also did a factory reset two times. The unlock is requested but I have to wait for 168 hours.
Thank you and with best reguards.

Stock MIUI is kinda laggy with lots of bloatwares. If you compare those phones, make sure to take into account of their hardware specs and default softwares.
You can search for how to make MIUI run more smoothly.
Thank you, I replaced the phone now by a Poco F1.

Haha, now that is A solution !
My Note 7 fell into the sea, so I changed it with another Poco. Now my Huawei Mate screen is screwed up, I had an excuse to get another Note 7, but this time from online, so much cheaper from China.
I think the Note 7 is very good, but I had it rooted, and unbloated, and other stuff.
Dont see why for me it performs really well, just have to optimize it, unlock bootloader root custom ROM and custom kernel
My 24/7 settings Alucardshed governor limited to 300-2150
HW Prime
Antutu
I also had a antutu of about 142000, this seems to be normal and also okay for the phone. My biggest problem was, that there very little lags when scrolling in the menu or e.g. Nova launcher. Also switching between apps took really long, not because of a lack of memory more because of the apps were closed too fast and had to be reloaded really often. When you turn the phone on and want to have a quick look on faceboo, the app har to reload nearly every time. I know this is high-level moaning, but it just drove me crazy.
The phone is okay, you always have to keep in mind how much it costs. But I did expect more from it as in Germany it was praised as the midclass-killer phone.

Poco M3 very slow?

Hi guys, I just bought the Poco M3 and I find it very slow, not only on opening apps but also things like opening recent apps menu, popping up keyboard, etc. Anybody else is experiencing this? The specs are pretty decent so I guess it's a badly optimized OS. I've used MIUI before and I liked it so I'm kinda disappointed.
I should receive mine later today, I will come back here after some tests and tell you.
Awesome! Waiting for your input.
I've been playing with it for about an hour now, didn't install many apps though (just a few basic ones).
It does have some lags like you said (drawer, keyboard, opening apps...), but I find it alright for that price point.
Yeah, the CPU should handle that a bit better, but MIUI 12 isn't really known to be a light Android skin. I don't think they made much optimization for the M3, it's probably the same as the more powerful POCOs.
Overall it's fine imo, but I agree it should be better for the hardware inside.
As a small update, I might add that after using it for a bit longer some of the lag went away, but it's still quite slow to open apps and do multi-tasking.

Thanks for your reply! I know the phone is super cheap and I shouldn't expect too much from it, but I've used MIUI before on even worse hardware and it was pretty smooth, so I was surprised by the lag. Nice phone otherwise(except camera which is pretty bad IMO). I didn't use it too much since it's not my main phone, but I'm going to use it more maybe it will get better. I'm also doing a hard reset. I hope it will get LineageOS soon, that would be awesome.
Yeah I see your point. I'm a Poco F2 Pro & X3 NFC user, so I also find the phone quite laggy, but it is acceptable in my opinion. But I do hope they will make some updates to improve performances, even just a bit.
(I recommend checking out the GCam thread I made for the camera, it gave me quite some decent results)

Hmm, I'd say with this update (as well as replacing the Poco launcher with Lawnchair), I did notice some performance improvement, yeah.
I wouldn't say by a lot, games still have the same amount of lag, but scrolling and opening apps definitely feel smoother and perfectly acceptable now imo.
