Redmi Note 9 Pro random freezes and reboots itself - Redmi Note 9S / Note 9 Pro (Indian Model) Question

My Redmi Note 9 Pro keeps restarting randomly (mostly when i use the camera). It just straight freezes and restart itself. Recently it only happens when opening the camera, but now it also happens when i playing games (CoC/CoD). Anyone who shares the same problem?

My Note 9 Pro EU starts to reboot after the recent EU update. But I saw this issue only when the GPS is on and phone working as navigation. Sometimes it can reboot after 30 min, and sometimes after 2 min, time to reboot after turn on navigation is random :/. I thought that is software bug so I unlock bootloader and flash newest xiaomi.eu but it didn't help :/

Have you tested your GPS on the test menu?
You can enter it with few clicks on KERNEL VERSION at "My device" in the settings ?

Unfortunately it's seems that GPS is OK with that test. I even revert to EU 11.0.1 and problem with GPS still appear. So it must by something with my unit :/

Tried turning off the option "Use assisted GPS" ?

if you check on here: https://c.mi.com/oc/miuidownload/detail?device=1900378 that recent update for 11.0.4 was pulled due to issues.
thats why i always delay updating the phone when a new update comes out. give it atleast a week or 2 to see if its safe. in this case it got pulled in a day.

Same problem here.
This error occured with all these official version
11.0.2
11.0.3
11.0.4
this is frustrating me.
any hel?

Same problem with 11.0.1 and 11.0.3 reboots while using GPS incl getting hot (maybe thats the point for the reboots) and also while using WLAN with network certificate...
Need help too. All GPS related options are disabled, any further ideas using advanced options?

Is this related to WiFi issue?

Last time i was trying one thing. I turn off access for many apps to GPS (system apps etc.) and run navigation for whole night with plugged charger and screen set to 100% brightness. And for my surprise phone did not restart! For test time my Redmi Note 9 Pro was running on Xiaomi.eu 11.0.4.
So maybe it's software bug? Because earlier my phone was restarting even when screen was off with navigation running. So for me it's not heating issue.

I'm having the same issue. In my case the phone will freeze/reboot instantly if a foreground app, such as maps or the camera, accesses the location, and will occasionally reboot itself while sleeping if location is enabled. Wiping the phone seems to correct it for a little while but the problem always returns.
So far I've tried stock roms 11.0.2 and 11.0.4, and Xiaomi.eu 11.0.4 and all have been affected.
I'm going to have to install a custom rom such as the GSI AOSP one and see if that fixes it. If the reboots still happen on a rom not based on stock, I'll have to return the phone. A phone without GPS isn't of much use to me.

I use AOSP + gapps and don't have reboot issues.

Well I had no issues on 11.04 EU, while using GPS but if connected to a known WiFi it reboots sometimes. While further investigate the GPS ...

Mi note 9 pro max hanging and rebooting problem.
After updating the software to 11.0.4.0 still it has rebooting problem and hanging.it freeze and start rebooting .. someone has any solution please help me

My Redmi Note 9 Pro with MIUI 11.0.4.0 stable Global reboots itself every now and then! When I am on Chrome it freezes and restarts!

I just got a redmini Pro 9 note some weeks ago it's been hell. It keeps saying "device shuts down unexpectedly" go off and comes on cannot do anything meaningful because it happens so frequently. I have rebooted, fast rebooted million times. I really regret buying this useless phone

On mine, After flash custom rom, give the same problem

Anyone solved this reboot issue? How?
My brand new note 9 pro (global version) randomly reboots with no apparent reason. It may happen while sleeping or while in use. It happens once every day, more or less.

No news? Have you asked for a replacement or was it a software issue? Please help, mine reboots once a day on average and I have to decide if returning it (bought through Amazon)

Random screen blank outs

Hi,
I'm facing a strange issue on Redmi Note 3 (SD) for past couple of weeks. The display suddenly turns blank, while all other things are functioning. If I try to turn off and turn on the display immediately, the screen remains blank. However, the problem automatically resolves itself after a few mins. I thought this could be due to heating, so I cleared up a lot of storage space and uninstalled all unnecessary apps. The problem still persists.
It is completely random. The display will suddenly turn blank, and will be back to normal if I unlock after a few mins. This is really frustrating. The things I've tried (and failed) include:
Removing and reattaching the cable connected to the display port
Cleaning the entire board
Storage cleanup
Battery optimizations
Temperature oversight
Has anyone else faced similar issue? Are you aware of any solutions?

System lag after 24hrs of use

I don't know if it's just happening to me, but after upgrading to Android 10 the system really got faster, but after an average of 24 hours of use and especially after loading it 100% again, the whole system and apps seem like start to lock up, you can see a huge difference in the speed at which I use apps and when opening apps, apps get less fluid in the passage of news feeds, sometimes the phone gets to lock up, but you just have to restart phone so that it goes back to fast again.
Is anyone with the same problem?
On Android 9 I don't remember this happening
In short: I need to restart the phone every time I charge it so that it doesn't get stuck
Yes it's happening the same way as you described after upgrading to Android 10.
It seems like there is a RAM memory management OS bug
Yes you need to restart the phone then only it gets to normal state.otherwise keeps lagging.
If you just remove the app from background,I saw No memory is released from RAM(With CPU-Z).must be memory management issue
Same problem
Are you guys on global or EU? I don't have this problem. And I haven't done a factory reset since updating.
Using latest stock OTA for global, btw.
I am on EU version for me uninstalling chrome to factory fixed this issue I am running for 60h and no slow downs
Old post but can confirm disabling built in Chrome solved the problem for now.

Touchscreen lagging since miui 12 upgrade

Hi
I have recently updated/flashed ROM to miui 12.0.6.0 (QJBEUXM). Since the update, touchscreen response is lagging.
Sometime it dies for few minutes and some time I have to press many times or very hard. Restart helps sometimes. This is frustrating. Everything else seems to be working fine.
Any clue how I can fix this or downgrade back to miui11.
I had issues with twrp and tried 2/3 different varient. Can this cause it?
Many thanks
Another a bit late.. I think I know what you mean. Everything freezes for a few seconds or more. I found that it is most common in chrome and how to defeat the lock up is to pull the notification slide down (slide from status bar downwards) and immediately close it. It should jump back into life.
No clue what causes it but it related to chrome somehow..

Xiaomi Redmi Note 9 Pro question

1 Question: Hi guys i made an full backup of all directories with orangefox I mean really all directories (boot, dbto, etc...) (backup was made on the same rom, I used the stock kernel) and flashed stock miui rom V12.0.2.0.QJZMIXM (I made this backup and flashed the same rom because I wanted to install a kernel and I didn't liked it) and started to restore my backup from xiaomi cloud, then I entered in orangefox and flashed my backup of all directories above the stock rom I installed. Won't be there any problems if I did this? (I mean, is this wrong that I flashed the backup above existing directories?)
2 Question: Also I don't really remember if I had this problem before flashing stock rom but now I Viber when someone calls me or I call someone after I accept the call my screen just makes black and I can't open it, so I can't finish my call in Viber. I checked some settings in Viber and I turned off the setting "use device proximity sensor" (my proximity sensor is working fine with simple SIM Card calls and other apps) and now my screen doesn't turn off but viber makes a black screen and I need to exit viber and close it then I enter again in Viber and I can see with who I am talking (turn on microphone, camera...) I mean Viber call screen and I can talk normally, and I need to do this procedure all the time to see the Viber call screen.
3 Question: I think my battery is draining a bit faster than it was, or I'm just paranoid. How you know, after charging xiaomi phone it shows how many hours remaining (how much it will work), I charged it a week ago and it said 44 hours and 30 minutes or something like that, and now it showed me 43 hours and 30 minutes. Can you say if u have or had an xiaomi redmi note 9 pro after you bought it how much time it showed that battery will work (how many hours). Should I fully discharge my phone and charge it again to see how it's discharging, could the problem be because of what I did in Question 1?
Thank you! Hope someone will answer all my 3 questions

Redmi Note 4 Bootloops - nearly always

My ol' Note 4 nearly always bootloops since a few weeks.
So I get the MI logo, and that's where it typically stays.
Sometimes I get to the login screen, I can login, but after a short while it jumps back to bootloop mode.
Is there any known solution? (I know, this phone is getting too slow anyway)
Is it getting stuck on the redmi screen or the miui screen?
Try backing up your data, then flashing the stock miui rom for your device using mi flash tool.
If you're still having issues (which you shouldnt after flashing stock), then maybe try a custom rom?

Sorry for that late reply!
It can stay on the initial black 'mi' screen for quite a while, like 10 or 20 Minutes, or longer. The android dots are moving.
Then sometimes it goes to a blue screen, and sometimes to login (keystrokes) - mostly when I do to key strokes it jumps back the the 'mi' boot screen. Sometimes I manage to login and I can use it for some Seconds, or Minutes.
To me there is no logic in that behavior.
Try flashing the stock rom back to it.
Hi, I have the same issue. The above seems to work for me. But if you are actively using this phone for GPS, might not be right.

Thank you for your reply! I didn't touch the phone for looong time. The video gave me some hints. After many tries I managed to get to the normal phone screen - after switching Wifi off it seems to stop looping.
My aim to make a complete backup (which needs Wifi) and then transfer to a new phone.
This is more for my own reference > wisdom from video:
1) SIM out
2) Power off (5 sec press power)
3) On
4) Press vol key 10 sec during 2nd boot logo
5) After login > settings > additional settings > privacy > location > device only
Lets see......
...a short while later:
The method in the video that @kenny! posted seems to work. Phone operates quite normal now, a bit slow, but that's what can be expected from a phone that was already low-end in 2016.
Charging is normal. no more auto-power ON loops when charging. No crashes.
Thanks kenny!
