Sensor not working / random App-starts - Xiaomi Mi 9 Questions & Answers

Hello,
I have several problems with my MI9.
I installed in the past Iode OS. The display is not turning and the Brightnesssensor don‘t work. Also there are random App-starts from Iode browser. So many times that the phone was not useable.
So I installed original OS version 12.05 with Mi flash tool (clear all) but all problems are still there. Now the google search starts random.
What can I do?
Thanks for you help.

SGS camera issue

Hello everybody,
I've searched around this and other fora for my problem, but I found nothing. I bought my SGS about 2 months ago. It came with Android 2.1 installed and, through Kies, I updated it to 2.2 Froyo. After that, I decided to flash Darky's 9.2, as I heard a lot of good things about it.
After flashing everything was fine for a couple of days, 'till I started installing some camera-based apps, like Barcode Scanner and Google Goggles: I used them about three times, then they started force closing (Google Goggles) or showing a black screen instead of the camera view (Barcode Scanner). The situation grew worst and worst as my camera app started giving me a "Warning - Camera Failed" as soon as i switched to video mode. I read on Android Forums this problem could be caused by some of those camera-using apps, so I uninstalled both Barcode Scanner and Google Goggles, but nothing changed.
Other listed solutions were to disable lagfixes, change ROM/firmware, reset the phone, but none of this helped.
After experiencing those problem with Darky's 9.2, I upgraded to the new Darky's 9.3, but I still experienced the same damned issue. Thinking of some software issue with Darky's, I formatted the phone, disabled any lagfix I had and tried to flash Jimmy's/Hamster's v6.3. Well it's blazing fast, but I still have a similar problem: both camera and video mode work flawlessly, but both Barcode Scanner and Google Goggles force close, while Layar reports it is "unable to access camera hardware".
And now here I am, asking for your help. Thanks in advance.
Loads of posts on this subject on Darky posts suggest one you search them two you delete the rom and go back to stock .Then use another custom rom of your choice .

Thank you for your post, but, as I stated, I've already searched for my problem and no solution worked. Also, I've already flashed to another ROM (Darky's-> Hamster's).
I also have the problem with camera. Try to find the newest firmware and update it, maybe that will solve the problem.
When i updated fw, camera worked fine for a couple of hours, and then, iI don't know how, phone automatically switched to my old fw (about 1-2 hours after rebooting).
Then I have to restart the phone and camera works fine again with new fw.
It's so annoying, but i don't have the complete solution yet. Btw, i'm on Darkys 9.6.6.
Sounds like you're missing the stock email.apk

Apps shut down on 4.1.2

Hi,
i have a i9001 and use broodrom (4.1.2 version). I've tried some different roms, but there is always the problem with the "email" program provided by google: When i start the program it sometimes works and sometimes it crashes telling me, that the app was shut down. It always crashes when I try to answer an email. I've tried different email accounts with no effect. I tried different email apps and all have the same problem. Does anyone figure out, how to fix this? (i like broodrom and this is the only real issue)
There are mutliple threads about problems like this but i didn't find one that describes or solves a related problem. I tried out some things, cleared the cache, reinstalled the rom, i checked the gapps version to be the right one and honestly: I'm clueless...
gan
I tried some more things and finally i decided to try out invendors CM10 version. This one works.
Thank you to all the guys out there, that make such roms. Great work!

Official factory/stock lenovo freezing and shutdown

I would like to have more information if users have experienced the issue of often freezing and shutting down of the device on the k50-t5.
This is happening to a specific device that has never been rooted neither by recovery, not even by softrooting with applications such as kingroot.
A hardreset on the device through the lenovo recovery did not improve the issue.
A hardreset through the chinese recovery has not been performed yet.
I myself due to immediately rooting it have not tested the official stock rom to have more insight to compare it with this other device.
I'm not thinking of rooting this device since this problem, what i had in mind is also resetting through the chinese recovery and if the problem persists update a later version of an official stock rom to see if it has improved.
I would appreciate it tremendously if someone had more information over this matter or any opinions.
I have encountered many of these issues in the past yet all of were fixable. Mostly software issues or what comes into my mind is a defect battery.
Could be more however i am hoping for the best.
The device has been used one month and since 2 days ago frequently shows this issue.
Within an hour it has been 6 times the last being directly after a hardreset with no applications installed.
topic solved turned out being no hardware problem. it was unusual however for it happened also in the recovery not just the OS

I've tried I think about 9 ROMs in total now, some from hackerpower's excellent thread and some from NeedRom, including the latest ROW and Chinese ROMs - none of which have been stable for me. Well, the best so far was the Lemonchello Novamod, in terms of features, smoothness and battery consumption, but after a few days that too crashed and the phone refused to boot any more. The problems have occured often whilst using YouTube or embedded video, and sometimes just using a web browser (I've tried various).
What was the hardware issue you encountered, and what was your solution? Many thanks!
i havent been handson with the device having this problem, although the issue was due to official stock rom and recovery.

How to return to stock?

Hello guys! After experiencing all custom ROMS including Xiaomi.EU, figured out that every single one has some small inconvenience for me and planning to return to stock, eventually using only Magisk and potentially a custom Kernel.
Managed to install every single version of Global Developer ROM, everything works well except the FaceUnlock that was gone, (the phone remained stucked in China region) and I am not able to access the fingerprint section, after few tries it brings me an error message.
Tried also using MIFlash , but the Fastboot ROM writting took 3 sec to write and stopped as successfully, then nothing but bootlooping.
Currently is the phone is functional, but as mentioned before not able to setup new fingerprints (using cache and data from old recovery and those work) neither Face Unlock.
Tried to Google any kind of solution, but unfortunately nothing worked.
Any suggestion is appreciated.
I see that nobody is interested to support, so I continuously researched and figured out that doing a full wipe and following these steps from this post will solve my problem:

From I don't know which reason I was blocked on China region without the possibility to changing it.

Youtube Vanced not sending notifications, can't install older versions

Hello everyone!
I have an issue which is driving me crazy. I'm not getting notifications from Youtube Vanced on my Note 9 SM-N960F (Oreo december patch). I tried everything basically, every notification setting is on, and nothing. I came across a solution which seemed to work for other people, but for me it's not working. It said to install Youtube Vanced 13.10.55 first, and then update to 13.50.52. For some reason, when I tried to install that older version, my phone said "Application not installed." every time. I also tried with other versions, and it refuses to install any other than the latest version. Same with microG. What could be causing both of my problems and how could I fix them?
Did you remove the previous version?
