K20 pro got freezing and black screen after upgrading - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

so I have a k20pro device (chinese rom, imported from china), bought it last year. I worked fine at first. However when I tried to upgrade it to MIUI 10 (chinese rom). It got freezing and blackscreen. the store said it was the screen problem and suggest screen replacement. I refused due to the high price. Then I just put the phone there until today, after 8 month I open it and upgrade to UI11 and it is working better. it still has freezing but no permanent black screen.
is that the software or hardware issue?

I have same problem did anybody fixed it yet

Guys im 90% sure its hw issue, i had touchscreen issues till i got new screen. Sometimes when i wanted to check what time is it and unlock my phone, touchscreen wasnt responding till the moment when the touchscreen was completly dead. I think many k20s has some touchscreen issues, but for the price its worth it.

It is a software issue. It started after the upgrade to MIUI 12 and it mostly happens when I use the Uber app. I usually have to restart the device. It is not a hardward issue. I think it should be solved after the next update.

Random lag, freezes, camera problems. is this device flawed?

Hi everyone!
I'm trying to determine if it's only my phone acting up or is this device flawed by design.
Basically, the more i'm using it, the more it freezes for random amounts of time. I have to clear the RAM constantly, and when that doesn't work, a restart will temporary fix problems. It can be anything, like failing to unlock, or taking 10 seconds to do so, camera opening black for 10-30 seconds, etc. Literally anything can lag badly and randomly, especially under heavy use (or no use, considering it doesn't unlock).
Am i the only one experiencing this? I've contacted Huawei and they want to send my phone to China "for analysis" but this is absurd. I've got exasperated with this phone to the point where i emailed the founder of Huawei to challenge him to use this device for a week and see if he can. They actually responded. So, if this IS a design fault, then i will gladly tell you where you can complain "at the top". I'm just trying to determine if i'm a pretentious prick or this is truly a horribly flawed phone.
BTW, i'm on B115
My pra lx1 works great. Lags are rare.

Mine lags also same as yours
Hello, mine had that problem when I was on the b125 version, now I'm on b182. The problem was fixed for me when I updated to 170 back in october.
(Pra-lx1c432b182)
You should update with firmware finder or debrand your phone .
Hi there, I just wanted to say that I also have problems with my Huawei p8 lite, camera freezes up to 30 seconds, changing from front to back camera and vice versa takes at least 20 seconds, the phone is slow and not respondin as it should. I had it forba month and a half now and would love to change it for some other device!

I'm on B115 and it tells me it's fully up to date. AFAIK it's not locked to a network. Is there anyway to force it to b182?

Well now even my speaker is beginning to have problems with high sounds. Dream phone ? I will try to send it on warranty and I will see...
I also have this problem, noticed it after i updated to october security patch, tried reformatting multiple times but to no avail.
In my case not only the camera app force reboots my phone.
Speakers also have the same problem, at a certain volume level the sound breaks /lags.
Hopefully this is just a software problem, my phone doesn't have warranty anymore...
Did you try factory reset? Did it help? I am going to try it cause I need my phone for work and I don't want to be 30 days without phone.
No factory reset did not work, but I noticed that keeping the phone plugged into a charger keeps it from restarting.
Yes I have it same... It can be only problem with battery maybe.
Yeah, best to have the battery checked and replaced, hopefully I can find a service center here in the Philippines

I try to fix it from the care center.
They need to replace the mainboard, battery, and the loudspeaker. South Borneo, Indonesia needs approx 3 weeks for the indent parts. Fortunately, i still have the guarantee. Tomorrow i will give the device to them to fix the problems. Hopefully it works best result.
Just FYI, from my experience.
Yeah, same problem here. Phone restarting on opening camera, and when while watching video with volume above 66%
I've tried factory reset, and even reflash stock room but still doesn't work. Maybe it only happened with android pie? Anyone try downgrade to oreo?

I did every possibilities, did not work.
Downgrade too, manually by my self.
Downgrade by the care center also did not fix it.
Sorry to say it.
Its the hardware, dont know what cause it. Best possible its caused by the update. May the software cause the hardware broken..? ??
HMD, please... R u serious 2 produce a flagship phone?
Same problems here. HMD is crap!
I purchased this device in October 2017 and the problems have just amplified like crazy.
After the April update, random reboots, distorted audio, ultra slow charging.
A lot of money down the drain as this phone has NO RESALE VALUE either.
This is not a flagship. This is a phone made of all the leftover reject cheap hardware materials and hence it sounds good on paper.
The only credibility it has is because of Google and Qualcomm.
Honestly, after 20 months of use, I can say I've never used such a horrible device ever. This phone is pure headache.
what a disappointing phones by Nokia, disaster, disgraceful to users. I think this i s my last Nokia phone (at least last by HMD)
Guess what..?
Ive been waiting for 3 weeks for the repair.
The care center said rhat i must wait for 2 more weeks and then they will tell me the approx time to wait for more.
So,
3 weeks passed,
2 weeks more to wait an info,
Dont know if that after the 5th week the device is ready for use or not.
Wasting much money to buy this one.
I feel sick at once
Nothing like this. HMD is the only one who did this ever.
I too facing this problem for the past 3 weeks or so. Random restarts especially when starting the banners camera. Someimes 2or 3 such episodes. The problem with the sound cracking at high volumes I've been having for 2 months now. The problem increases when the battery guess below 40%. And decreases when it is being charged. ?? A battery issue. Maybe not because otherwise I've a decent battery life.

Question Redmi Note 10 Pro lagging after MIUI 12.5.2.0 update

Hi! I have a big and annoying problem. I have a Redmi Note 10 Pro phone that I upgraded from MIUI 12.5.1.0 to 12.5.2.0 2 days ago and have been struggling with lags ever since. I've tried everything, including a factory reset, to reinstall the phone from the recovery menu, but the problem didn't go away. It’s a pretty annoying problem that I can’t normally use my new phone I bought recently. Is it possible to downgrade MIUI from 12.5.2.0 back to 12.5.1.0? Or what should I do? Please help!

The same experience here, the device's performance has dropped significantly since updating to 12.5.2.0 and has terrible lag opening apps.
I'm still on 12.5.1, but have noticed that this broke the Google clock alarms - had that been fixed with 12.5.2?

I don't know. Since I have already managed to resolve to revert to MIUI Version 12.5.1.0.

Weird... I've reverted to the Xiaomi click app, but that doesn't give access to YouTube music as an alarm time source.

The whole MIUI system is a mess. That's all I can say... I don't understand why there are so many bugs in the system with a phone like this. Xiaomi Developers should pay more attention to this.
i've no issue but app bugs cannot solved
i decided to go with xiaomi.eu still waiting to unlock the bootloader , looks like there are many differences
I am on 12.5.2 and I have no issues.
Turns off and on and works perfectly.
UPI apps is not working in dual app mode. Does anybody else also facing it? Any solutions?

General Can't turn on WiFi and Bluetooth

Was about to put it as a [Question] but decided to place it as possible troubleshoot and experience for anyone with same problem.
Damn, was not expecting this and out of the blue.
I used my mi11ultra normally today, on Xiaomi.eu 12.5.11.0.
I order from Uber, while i waited, was playing asphalt 9. Then poof, lost my wifi connection. Could use mobile data.
At 30% battery remaining.
Couldn't connect to wifi and decided to reboot my phone.
For a few tries turning on wifi reboots my phone after freezing for a few seconds.
Sometimes it doesnt even turn on(no blue icon)
Turn off phone and let the heat dissipate. it's not hot today, and im using FHD res at 120hz, also haven't been playing for a long time, maybe 30minutes.
Tried restart i wiped daivilk and art cache on twrp.
Tried updating just now to 12.5.12.0 , nothing.
Tried Reset Wifi, bluetooth and mobile, nothing.
It lets me, sometimes, enable wifi, search for networks, connect and the wifi shuts down after about 5 seconds.
Right now as i was writing this and decide charged the phone so i could factory wipe. Im at 60% battery and the issue is gone for now.
I posting BOLD on battery comment because i found it that that was the issue oddly enough.
I'm charging the phone till 100% and will let you know if it happens again. "i hope i don't jinx it."
My greatest fear is that i would have to send it to repairs which takes time.
I Jinxed it . Going to Factory reset.
Watched abit of Netflix and then suddenly it freezed the phone and rebooted automatically.
EDIT: It's a faulty wifi module... Have to send it for repairs

Sounds like it might be a hardware issue if it persists across all ROMs
Do you have a warranty to get a free fix ?

It had warranty, yes, and it was the Wifi module but ultimately i decided to get a refund.
Curiously i read it's a Mi 11 Series issue, if you decide to search in google "mi 11 wifi issue".
So i have to say farewell to Mi 11 Ultra Community.
My decision was done with several annoyances from Xiaomi and not for the hardware itself, all the crazy features and camera are badass.
Lack of optimization,
Missing gestures navigation with different launchers(which other manufactures already fixed long time ago in android 11...)
Generic updates(same changelog for all devices) and lack of transparency.
I still advise my friends and family to get a Xiaomi device for what they get for the price and i keep getting impressed by the hardware in these devices.
Also love the ecosystem and new features being added every MIUI version.
I got a POCO M3 with Android 10 Xiaomi.eu, that works gesture navigation and doesn't need third party apps.
I think it all comes down to software, because in the hardware department there isn't any complain from me.
I might even get a Poco X3 Pro for 170€ for a secondary device and install some AOSP rom there.
This decision might change in the future since Xiaomi said they are implementing a team dedicated for software issues, but not to this device.
Until then goodbye
Just my opinion,
seems like all hardware issues are happening to people who flashed non stock rom's.
Fingerprints before, and now wifi and Bluetooth.
Glad I am with global version and stock rom (tried .eu for a while and found it garbage). fingers crossed to stay happy

Question Are there people without ramdump?

today i've bought my new zenfone 8, i was leaving a xiaomi mi 10 because of proximity sensor problems and miui instability.
read lots of reviews about zenfone 8 and all were enthusiasts... today after buying it i found a first post about ramdump, since today afternoon i've read lots of posts....
i've seen my phone is 04/21 MFD....
will it die? are there people wich had this phone (04/21 batch) without problems? searching around in forums seems that anyone sooner or later had the problem... so the phone is in the box and i don't know if i will return it or keep it... give me a little trust in this phone
Do you like to play Russian Roulette?
If you open the box you will have to.
I have phone of same batch 04/2021 and had ramdump once. But I easilly quit it with keys combo. I do not know why it works for some but not for others.
so there are people who never had problems?
cause i could see 30 people having problems, but i'd like to know if are 30 people on 50 or 30 people on 1000, it would be a big difference
Mine is mfd 04/2021 and I still have no problems
There is 35 confirmed cases of this issue and it might not be the same issue as Ramdump is just something zenfone 8 falls back to when there is a problem with the phone. Who knows how many (tens of thousands) people are there without any issues.
I would say relax and enjoy your phone. Don't unlock the bootloader so you don't lose the warranty, but other than that just use it normally.
I just checked and I also have MFD 04.2021. I never had any problems (not that I am aware of) so I never bothered to check before. Does the problem only happen on certain devices? I have the basic version with 8 GB RAM and 128 GB ROM. Happy customer so far.
EDIT: I am running stock firmware, if that matters. Haven't altered anything (yet).
Used it for more than 4 months without problems (bootloader unlocked).
With Lineage 18.1, it worked great for a day, maybe even less. Now I get at least a couple ramdumps every day.

The problem in the official forum is a "one time" thing, if you get the "waiting for flashing full ramdump", its bricked and you can't do a thing, beside sending it in.
On my brand new ZenPhone 8 running Lineage for Microg 8.1 October 7th version I'm getting the ramdump screen, but only under specific circumstances:
1. not connected to wifi/wifi off
2. on a call
3. have headphones plugged in to the jack
it almost always crashes within 20 seconds. If any of those conditions are not met it works fine (or at least appears to so far). I've tested this ~8 times in a row with all other (known) variables remaining constant.
When it crashes, pressing power for ~15 seconds shuts it down, and it can then be started normally. I hope this helps anyone else e countering the same problem.
Someone had this ramdump issue on unlocked bl but on stock rom? Especially with at least some magisk mods?

Yes! My first time with this issue. Never before.
I'm on the lastest Android 12 stock rom (UL-ASUS_I006D-ASUS-31.1010.0410.72-1.1.25-2204-user).
- Unlocked BL
- Rooted with Magisk 23
- Kirisakura_Sake_S_2.0.1 flashed with EXKM
- Only one Magisk module (Font_Manager-v5_6_4-117)
I was playing a game (Zombie Tsunami ). I got my screen freezing, ... dark screen and ramdump issue.
Edit: My MFD is 05.2021
I have too MF 4.2021 - using since 5-2021. I'm very happy with this phone. For all this time I'v got only landscape bug on video - fixed with OTA update.
I'm using stock soft - Android 12 31.1010.0410.72
