Redmi Note 8T app freezing

I bought my wife a Redmi Note 8T for xmas, and unfortunately it's been an absolute nightmare to operate ever since she received it. It works perfectly after a reboot, but after a few hours or perhaps half a day of use many of the apps on the phone refuse to open, they just display an all white screen or sometimes the logo of the app, but never open fully. You can close them, or press the home button to go back to something else but that app will not open unless you reboot the phone again.
I did multiple factory resets and re-set everything up but the problem always comes back. I ended up returning it to the retailer (I'm in Australia but the retailer was overseas), but they insist they couldn't re-create the problem, and refused to tell me if they were actually using the phone for a few hours before trying the apps...they seemed to be only ever trying it out after a reboot. I won't name the retailer but their customer service is extremely poor and I certainly won't be using them again. In the end I asked them to send the phone back to me, at which point they demanded $70 to return it as "there were no issues found". I paid it, got the phone back and then cancelled the charges on my credit card just to annoy them.
Anyway...I got the phone back a couple of days ago and set it up again from scratch, MIUI 11.0.5, added my wife's google account, installed half a dozen of her apps (FB Messenger, Whatsapp, Bring shopping etc)...she used the phone for about 2 hours then Messenger and Bring refused to open with the same problem. I can only imagine it's some kind of CPU or RAM issue. It's the 4gb/64gb model so it should be very capable of handling such a light load. Model M1308C3XG.
I figured I'd cut my losses so went and bought her the Mi 9 Lite from a local retailer yesterday morning and it's been working perfectly ever since. Cost twice as much as the 8T but at least I'm not copping an earful any more!
So...I have a new 8T that's has nothing to do....figured I might unlock the bootloader and try TWRP, see if it makes any difference. Did the unlock last night but it tells me I gotta wait 168 hours. Sigh. Anyone got any ideas in the meantime feel free to throw them my way.

Hi Bro.
Me also facing this problem. I am using redmi note 8 (Indian verison)4/64GB variant
I faces the the same problem u mentioned above.
Me also reseted the mobile but the problem still occurs.
Also me unlocked the bootloader and installed the original fastboot flash ROM. But still the problem occurs.
I don't know how to solve this problem.
If you got some solutions suggest me....

I never did get it solved mate, but you know what's interesting is that I can't recreate the issue without a SIM inserted in the phone. I transferred the SIM into the new Mi 9 Lite and it's working fine, and I have been playing with the Note 8T without a SIM...the issue hasn't come back. So my guess is this is a fault with the GSM hardware in this model of phone...it might only happen if you're using a certain frequency which is why not everyone has the problem?

Hi, I'm having exactly the same issues, even though I changed ROM. Seems like a hardware issue. Did you manage to fix it?

S20 Ultra keep vibrating till reset

Hi guys,
I bought an s20 ultra 2 weeks ago from HK, everything is fine but 2 times it starts to vibrate and cannot stop, even with all the apps closed. The only way to make it stop was reset it. Anyone experiencing the same issue?
Any suggestion to solve the problem?
I would like not send it back.
Thanks,

Coincidentally, I had the same issue a few days ago. It was related to Samsung Pay. I forced stopped it and that solved my problem.

Question Regular, repeatable shutdowns

Someone please give me hope.
I've got this phone yesterday and it keeps turning itself off when locked. If my phone doesn't receive a "wake up signal" like a notificationn or isn't in charge it will turn off in around 5 minutes (measured with a clock). This is not a sudden shutdown or crash ,you can see the logo on the screen.
Neither safe boot nor factory reset solved the problem.
Returning it and buying it again at the same price is impossible now so i'm hoping for a fix before the return window ends.
Can Xiaomi fix my (and probably others) phone in less than a month or is better to throw the towel now and go for a full refund?

Oh.. Had a few unexpected shutdowns Yesterday.. and one today.. but it's Not reproduceable.
Have you tried to enable AOD? Maybe this is a workaround....

Yeah, even with AOD permanently on after around 5min the phone shuts off. I've also tried running the clock app in chrono mode in the background with no results.
Rightnow i'm trying to reinstall miui 12.0.2 cause i don't understand if this is an hardware problem or a software one.
Also we don't know how widespread this problem is, a lot of people are happy with their F£ but it's impossible not to notice a problem this serious

Just ordered the phone, will come in a week, what version of MIUI does it come with, Global stable or Global beta?

Bro try unlocking bootloader and installing xiaomi.eu

Xiaomi.EU on 12.6 is released with the gesture fixes as a fastboot ROM. You can give it a try.

I have the same problem. Got it yesterday, went to sleep and in the morning the phone was rebooted/crashed.
Had to put in Sim pin and Device pin again just like after a reboot.
I hope this gets fixed soon.

Same problem here, I have the f3 for ten days with MIUI Global 12.0.4 (Italian Country), several reboots (four) almost always at night under charge, but once even during the day in front of my eyes, another time I have found the smartphone completely turned off, at this point I don't know whether to ask for a refund because I don't know if it's a SW or HW problem
There are several users who are reporting this problem

Hmmm i think the update from yesterday solved the problem for me.
I didn´t have a reboot this night.
Edit: Had another reboot this night, so update didn´t help.

UPDATE: i've updated the phone to 12.0.4 and the problem still remains. i will ship it back to Amazon in a few days. Also the problem got even worse ( before update): it's the second time i've found the phone with 0 charge after one of those shutdowns. The "when isn't in charge" part of the OP is also wrong, in the last days the phone switched of even while charging

Had a reboot this night on 12.0.4

Before putting it definetly inside the box after factory reset i've tried to start the phone again and then lock the screen at the welcome page. After 10 mins i've found it turned off

Same problem for me. I wonder, does it also happen on xiaomi.eu rom? Hope its not a hardware fault.

Pretty sure it´s just a software Problem. During my search for a solution i found out, the Poco x3 had the same problem.

That can't be, if it was a software problem all of us on MIUI will have the same experience. I think mine is a hardware problem cause is worse than anyone here. Also a lot of people do not have any problems so maybe is a QC issue on some component like the power management chip

I dont have any shutdowns or reboots at night, but i use an old charger with 800mA.
My Shutdowns come If i disable AOD.

Question Updated to MIUI 12.5.3 and fingerprint sensor stopped working.

Hello everyone! Hope you're doing ok!
As the title says, I updated to MIUI 12.5.3 Global stable rom (from OTA) and then I started having issues with the fingerprint sensor, only working half of the time. Then, suddenly, it stopped working completely. I've read online that it has happened to many people on many devices. The only answer I can find is to flash xiaomi.eu rom on my phone. Does anybody knows if installing xiaomi.eu would help? Does anybody have had this same issue before?
My phone is 3 months old, I always use a case and screen protector, and I haven't dropped it strong. (It fell off of my hands a couple times, 2 or 3, but without any major impact, had a very safe landing haha so I doubt the fingerprint sensor broke.)
I'm trying to find any kind of solution to this problem, as I always use the fingerprint sensor
Thanks in advance!

I'm having the same problem, any fix?

Same problem, any fix???

I have bad news. I managed to install xiaomu.eu, I'm on MIUI 12.5.5 and sadly, the issue was not fixed. I thought that installing the most recent version of xiaomi.eu would solve the problem, but no...
I don't know if going back to MIUI 12.0 would solve it, as the problem appeared when I upgraded it to 12.5.3, but I won't try it for now because i'm kinda tired of re-setting my phone and apps lol.
If someone downgrades to MIUI 12.0, global or eu rom, and it solves the problem, please let us know!

it won't be solved by changing ROMs as it's an hardware issue. Go to the service centre and get it replaced

The thing is I'm not so sure its a hardware issue. The problem started when I updated to MIUI 12.5.3 and the fingerprint stopped working, and more people have the same issue after updating too.
But as changing the rom didnt work, I can assume maybe, in my case, is a hardware issue... And I doubt it tho, because I haven't dropped my phone as hard for it to broke.. unless the sensor is so weak it breaks with a little drop

I had the same issue, unlocked bootloader, flashed crdroid, and fingerprint stopped working, thought it was due to custom rom, flashed OG MIUI Firmware locked bootloader and fingerprint still wasn't working, claimed my phones warranty and the service center told me that they'd have to replace the fingerprint and the problem maybe with the motherboard as well.

So it is an hardware problem? Seriously?

Yes, it's a hardware issue. Last week I brought my mi 11 lite to the service centre and they replaced the fingerprint module and it's working again

So why the fingerprint with the previous software still active?

Happened to me 2 days ago, phone was just 3 months old.

It's hardware issue,sensor on mine Mi 11 lite 5g died two months after I bought it.Flashing older roms won't help...In my country there is no way to raplace it so I've got other phone...

Im not use fingerprint use faceid

Redmi Note 8: Phone restarts if I click any app

I have a 2 year old Redmi Note 8. For these years I have used it with utmost care and so it is in pretty good condition not a single scratch.
Now suddenly from the past few days, my phone restarts on its own. If I open the Camera app, or WhatsApp, or YouTube. But if I use the phone while charging everything works like new.
I have already tried factory reset twice. I have tried charging the phone to 100% but still same issue.
At some forums I found that this restart problem resolves after factory reset, some people replaced the volume/power button but I think it is a battery issue.
If any one of you is facing the same issue or want to share any advice, please do comment. Any other checks you want me to perform.

if factory reset did not fix it then it should be hardware issue, mostly battery (since it works while charging)

The service center needs the original bill or bill printout if I have ordered online. Since it is been a long time I forgot how did I order? I couldn't find anything on my amazon, Flipkart, MI account, no email regarding this purchase on my email.
How can I get the bill for this phone purchase? I have the IMEI number.
