Mi 8 does not turn off or reboot after some hours turned on

I'm having the same problem in all versions. After running on the phone some hours, if you try to reset or power off the phone, it doesn't turn off at all. The screen goes off but the phone is still on. It keeps working. It can be tested turning on flashlight and powering off or resetting it, the flashlight doesn't turn off. It does not turn on again until you force reset by pressing a while the power button. I think it's related to the GPS problem, after some hours the GPS stops working, and this problem also appears.

Looks like I have the same problem.

I think its a firmware issue, because I'm not the only one affected by this problem. Two friends on miui 9 and me on miui 10...

Nvm got the same bug.

I've installed with miflash latest miui 10 global beta, ant the problem is still here. I've found this problem only when gps stops working

I just noticed that I have the same problem.
If I want to reboot the phone after a few hours he won't reboot and the screen stays black very annoying problem.

Same problem with last miui 10 eu

Dont have this problem on official global beta miui 8.8.7, sounds like software related issue to me rather than a hardware problem;

Yes, I think this because before unlock the bootloader and flash the miui 10 Eu i dont have this problem

Seems that this problem is fixed with the last miui 10 Eu 8.8.9

I have now this version and the problem is there again... installed with miflash. 8.8.7 is still buggy with GPS and reboot. Let's see 8.8.9...

Xiaomi.eu has noticed this problem on their latest version too: https://forum.xda-developers.com/mi-8/how-to/rom-miui-10-8-8-9-xiaomi-eu-t3827802 (see changelog)

Hello guys, I'm facing this problem too on MIUI Global Stable 9.6.4.0, I reported the issue on MIUI forum, it would be great if you could kindly confirm my bug report to obtain more attention. Thank you. http://en.miui.com/thread-3726710-1-1.html

I'm facing the same problem! Just bought mine "Global Version" from China with MIUI 10 9.5.31 Beta.
In 4 days it rebboted 6 times, the last one happened today and I realized it was when I was unlocking the device with the fingerprint scanner.

exactly happened with me.

I have the MIUI 10 Global 9.5.31 Beta. I have random reboots during phone calls. Always had them when connected to the car bluetooth.
Do you know how it is possible to upgrade the ROM? Are there updates via OTA?
Thanks Gianluca

Honor 9 lite camera & flashlight problems

Hi,
I'm hoping someone out there can maybe help me with this please?
I have an Honor 9 Lite (LLD-L31C432) & recently the camera & flashlight stopped working. I've tried a number of other camera apps (the P20 ported camera, various google cams etc) but none work - all either open to a black screen & shut down immediately or else just say the app has crashed, etc.
The phone is bootloader unlocked and was on stock rom (LLD-GRP2-OVS-9.1.0.121). A few months ago I switched to Openkirin's Resurrection Remix OS 7.0.1 Beta 1 ROM & all worked ok (I had the stock camera, a Google Cam version and the P20 camera all working), but due to bluetooth problems I tried the Openkirin AOSP 10 Preview 1 ROM. Had a few problems with this one so tried to return to the stock ROM and had a lot of trouble getting it working again (bootloops, etc).
Eventually got the stock firmware back on but then noticed that the camera & flash no longer worked. Since then I've returned to both the Resurrection Remix ROM and the AOSP 10 Preview 1 (& Preview 2) ROMs but the problem still remains. Is it possible that I've broken the camera when fastboot flashing or using TWRP? I 'went around in circles' so much whilst trying to get back to stock that I can't remember ever step I tried, but it would seem a bit of a coincidence if the hardware failed just around the time of me having issues returning to stock ROM.
Also, If I was to relock the bootloader is it possible to tell that it has been unlocked in the past? It was purchased May 2018 so would still be in the 2yr warranty period but I wondered if Huawei could tell it had been unlocked in the past (I also read somewhere that the warranty is invalidated just by registering to get an unlock code, even if you never actually used it? - not sure how true this is!)
Cheers!

Galaxy Note 8 SM-N950F camera not working

Hey guys,
So basically my camera stop working. Two days back update the phone to the latest firmware (Android 9) and security patch (March 1). Installed TWRP and rooted with magisk. So far everything was working fine. Today needed to restart the phone and after the restart my camera disappeared. In camera app I get just black screen without error. Same thing happen with third party app. Trying in safe mode, same results. In an app
iDevcheck under camera tab there is nothing, no information at all.
Ideas?

Bump,

If it was me, I would flash stock filmware with Odin to see if it resolves the issue, if it does not, it is probably a hardware issue, in my opinion, or maybe the camera ribbon cable has disconnected somehow.

''Can't turn on flashlight because the light is being used by another app''
This is what I discovered today. Still kinda think it's a software issue. At the moment don't have the chance to flash stock firmware.

Factory reset?

Factory reset did not helped either.
I guess something went wrong during the rooting process.

Do you solve this problem?

i started having issue with my camera after 12.5.9 update my default miui camera app would close after clicking one photo although it was working in other camera like snapchat or fj camera. But few days after 12.5.10 update both front and back camera completely stopped working.
I unlocked my bootloader to downgrade the rom or flash custom rom as this seemed like a software issue . But after a week when i downgraded to my surprise the issue was still there which implies that the camera hardware has failed . So i dropped the idea of installing custom rom and instead went to service center, now they are replacing the motherboard as its hardware issue . I am gonna get back my phone today from service center so will update you guys accordingly .
Blog Link - This is the blog link which discusses about same problem even xiaomi has accepted the issue.
Its weird that software update can cause hardware bug but what i think is that with the update kernel setting might have been changed which can cause over voltage to camera module or something. Its my wild guess i don't have much idea about it . I would love to know it from experts out here .
