Phone reboots after fully charging on MIUI11 - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello,
I'm experiencing issue after MIUI11 update. Every morning after overnight charge fingerprint and pin unlock no longer work(so pretty much I can't access phone launcher), and then I hold power button and after 30 seconds phone reboots itself. I did not experience this issue on MIUI10. Did anyone experienced something like this and know fix for it ? I still did not try to do factory reset. I tried to figure out why it freeze but logcat don't say anything interesting and things like /proc/last_kmsg are not accessible without root. If anyone know how I could find reason for this freeze please let me know.

Yes, i can confírm that the battery drain and overheat still ocurres in miui 11. Updated to miui 11.0.1.0 yesterday and today the phone goes warm and sucks all the battery again. seems this is a major bug. We need to think in a way to contact xiaomi all together
And happns exactly that you describe. Does not turn on, phone warm, and need to press power button for a while to restart

N1 Turns off by itself

Hi everyone
Annoying issue. My phone is turning off (power off) randomly. Sometimes I take it out of my pocket and it is off. Then I have to reboot again with power button.
Anyone else has the same problem?
I am using CM 5.0.5.3.
Thanks
Mine reboots regularly but my phone is stock

Mine is running stock & has never ever turned off . You might have a faulty phone or problem with the rom you are using.
I had the random reboot problem on stock too, but it never stayed off.
Still happens on CM, but much less often.
Can you reproduce the problem? If so keep "adb logcat" running and see what the error is.
try pulling the last_kmsg from the phone..... Some information in there. Will at least let you know if it is hardware or software crash......
thank you martin
Little help. How do you pull that particular file?
thanks a lot
its a file, probably named so becasue it contains kernel messages (errors, debug).
Located at /proc/last_kmsg
you could pull it, tail it etc
example: tail -f /proc/last_kmsg
Yup, have the same problem sometimes
Both on stock and CM
Now I am running Modacos desire rom, and so far I don't think I have hade any unexpected reboots or shut downs
I have a similar problem but mine will sometimes turn off and not go back on for about 5 mins or so, sometimes longer, pulling the battery or even plugging it into the charger doesn't even give me the orange LED. it goes completely dead. it also sometimes gets stuck into boot mode like loop. this is on a stock N1 but this happens maybe 2-3 times per month. HTC said I can send it back or have it repaired but it's too much of a hassle and at least mine doesn't have dust under the screen if the problem persist I'll prolly send it in. BTW it's not a battery issue because I have two batteries and it's happened with both. faulty phone for sure.
I've had this happen once or twice the first couple weeks I had the phone.
It started happening to me when I installed appbrain and appaware so I uninstalled both and not done it since, so for me I think it was one of those apps!
Mine has done it once, I'm guessing it was an app that did it since one time in nearly 3 months isn't that big of a deal
I am still investigating. Its wierd that it happens morewhen I put it in the pocket. Its fine when its on the table
I have the same problem. Noticed it only happens when radio signal is very weak and a phone call comes in...Don't know if that makes any sense :S

Phone going crazy

I'm having some serious issues with my phone. This morning the battery was suddenly drained completely, don’t know why yet. Then after charging the phone a bit and rebooting it, it constantly goes into driving mode and starting the voice command application. The most strange thing however is that when I choose to power off the phone, it shuts down but then automatically reboots.
I know I should try factory reset, but anyone else had this problem?
(I have original firmware and the phone isn't rooted)
EDIT:
Doing a hard reset seems to have solved the problem.
Maybe your power button is broken (constantly pressed)? Did the phone get wet?
I have not heard of this. I've heard of bootloops and the phone rebooting when trying to power off but thats usually due to custom roms and people flashing over other custom roms which causes conflict. I think factory reset may be the only option. However, with the Galaxy S there used to be a way to get into safe mode. I beleive you'd hit the menu button as soon as you saw the Galaxy S boot logo. I haven't heard of a safe mode yet for SGS2 but perhaps someone can confirm if its available in this model?
If you can still get into settings of the phone when its on, I'd try going into Settings > Applications > Manage Applications and clearning data for voice commands
It almost seems as though your phone is registering home button being clicked thereby turning voice mode on and also turning it back on after a power off.

Hi,
I was have exactly same problem, reset don't resolve my issue.
Solution was to replace my phone.
Thanks for the help, gonna try factory reset first. But this doesn't look like a software problem, so probably gonna need to replace it

Well this is a strange problem. Is it possible a bread crumb got under your buttons? Or some case is so tight it is pressing on some buttons?
Don't have a case around it, but the power button isn't stuck I think because wouldn't the menu for shutting down the phone etc. appaer constantly? And if it's something under the buttons then it is just bad design, had the phone only a couple of weeks.

I had the same problem mate. And that was exactly what I thought, I actually started a thread on this problem about 2 weeks ago. Was really strange, people told me to take it back. But What I did was factory reset on the phone. Which still didn't completely solve my problem. So I left the battery out the phone over night. The most annoying thing was, the screen kept turning on, like something was being pressed, can't have been the middle button, because the menu would have come up, it didn't do that. And then to make matters worse the tap to speak driving mode kept coming up.
I then took out the battery and left it out over night. Put it back in, in the morning. Charged it up. Didn't do it again.
Hope that helps. Try it.
Ok thanks, I will try it. It is really a strange problem as you say. After the factory reset the problem showed up again but not as often as before. Also after upgrading to latest firmware today, according to the battery monitor android OS is using 45%, that looks really strange to me.

Nexus 4 screen freezes randomly, no reaction when touching.

Hi everyone!
So I just had this problem after I woke up yesterday. I googled a lot but only found similiar problems.
Let me tell you what happened chronologically:
After turning the phone on in the morning it started updating apps as if I was doing a firmware update: "updating apps 1 of 135" etc. Note that my nexus was already running on 5.1.1 and had the latest updates installed.
Now it randomly freezes the screen on whatever screen it was before it happens and it won't respond to any touch input. This can also happen when not using the phone, then it will freeze at the lockscreen (the time freezes with it so sometimes i can see at what time it froze). Also, it loses connection with Wi-Fi as i'm using Whatsapp Desktop when i'm on my laptop and it mentions me that my phone is not connected.
The only thing that "fixes" (temporarily) it is a reboot. Now sometimes, on the lockscreen, i can just hold the power button and the pop-up comes in to turn the phone of, which i can somehow just tap on an it responds by turning the phone off. But sometimes (less frequent than the latter mentioned) the pop-up doesn't come in and holding the power button for a few secs will do the trick.
I hope I informed you all enough and my end question is: does any of you know what this is? How i can fix it or what i can do to prevent it or anything as I am hopeless. (my G3 is up for reparation so this is my sisters old phone, i had a nexus 4 myself for 2 years before the G3).
Thanks in advance!!
The best way to test it is by reformat the OS.
I positively think that it will solve the problem.
Since the phone is no longer under warranty, I guess there is no harm to install custom rom on it. They are fast and stable too.
Hope this help. Good luck.
Sent from my Nexus 4
EXACT thing happened to me too. Backup your data and hard reset from recovery. This fixed it for me
Same problem here bro, but neither custom roms or factory reset helps.... Is there anyone who has successfully solved the problem ?

Then it's time to change the screen or phone. Looks like it is a hardware issue.

I agree, your screen needs to be replaced.

Nougat update sleep issues

Is anybody else experiencing screen issues after the nougat update?
i find, periodically , particularly after disconnecting the device from hdmi and closing the lid that upon reopening the device its wholly unresponsive and requires a long hold of the power button to reboot the device?
there doesnt appear to be a constant but it never happened in the year odd of ownership prior to nougat? Any ideas?
Yep, same issue. Android System is consuming around 50% of the battery, when it was around 10% before the update. The upper back of the bottom also gets much hotter than before. Already created a support ticket with Lenovo but haven't heard back from them in almost two weeks.
Me too. Same issue.
Any answer in your case from the supportticket?

I was having this issue too. Seems to have been resolved with a manual cache wipe through recovery. Hasn't happened in the last 24 hours even with long periods in sleep mode.
Same Problem but in Android 6

I have exactly similar problem but in Android 6 Marshmallow. I have system updated many many times. Today there was nougat update available but I have seen may users complaining about different issues regarding Nougat version. So I have not updated yet. Since I have the same hibernation (screen off/ shutdown) problem even before the update. I am thinking of updating to Nougat.
I tried many methods but did not succeed. If you have found out any solutions please share with me. So will I.
Thank you
Were you able to solve this problem? I've been living with this for the last year. When the device goes to sleep it can't wake up and I have to press the power button for 20 sec to reboot it. Very annoying since it gets hot and uses the whole battery while stuck in this mode.

The phone was warm when it shut down?
Nope, just turned off, I can turn it no normally, it never heats up in what I use it for, maybe little bit on app update, but the shiwdows are not after updating apps, seems pretty random, I did not found any error log or anything
I was having all kinds of issues after updating to miui 11. Including phone turning off, battery drain, lags, etc. went to Update system, tabbed miui 11 logo many times. Once extra settings was activated, tabbed top right corner (3 dots) and tabbed on download latest package. After phone updated everything wad fixed. 3 days already, no issues. This option downloads same version but full file, more than 2gb, please try.
I had updated my phone to miui 11 using the full package still
sudden shutdown happened to me today.

No, no sudden drop in battery line, Yesterday I had another sudden/force shutdown but it happened when I was using it, touch was unresponsive, only physical keys were working, Power button would lock the screen, volume keys were able to change volume bar, but nothing else was responding, If i had left it in same condition it would have shutdown itself but I couldn't wait so I had to press & hold power button to force reboot.
MIUI seems to be not so stable.

Some problem.
EU version or Global?
It turned off twice today. I have global version, Updated to MIUI 11 and have had same issues (battery drain, turning off,...). I turned off all auto start apps and it fixed the battery drain. Before turning off itself, screen and buttons do not respond, screen is black untill I double tab to turn the screen on, then it shows the unlocked screen (even though I didn't unlock the screen) with no status bar on top (there's a solid black bar instead) and then it turns off itself.

If it is software dependent you must reflash the full rom not only to update that can't cover your issue.
If you are locked bootloader use provided MI recovery.

Said the FULL package and not only the "update ^pack" that is just a part of the full package.
You find the exact rom number you already have in your phone and reflash it saving your data in advance because phone will be erased.
But, first did you try a factory reset in order to check if issue remains?

Thanks for your response. I haven't. Factory reset wouldn't be my first action. That's why I've been searching for suggestions before doing anything. Btw, the issues started after I updated to MIUI 11. I'm not familiar with mobile technology so looking forward to detailed fix though...

I have the exact same issue, device heats up (in pocket for example, when idling), and randomly shuts off at a random moment hours later Since Miui 11
Same issue here. After 1 month of use without any problems, it happened to me twice yesterday.
Having same issue. drops like 20-25% in battery once i turn it back on. weird...already installed fresh new rom etc. Only since mui11
