Weird problem with charging/fastboot - Xiaomi Mi Mix 2 Questions & Answers

Hi there,
I got a really weird problem with charging. If I boot up my phone while charger is plugged in, it goes straight to fastboot. Furthermore my phone charges really slow while phone is on (system, OmniRom-weekly in my case). When I use bluetooth and play music for instance the percentage even goes down while being charged. Any idea what is causing this problems?
No weird apps installed, same thing happens with different chargers. I already flashed other kernels, wiped cache, even formatted and flashed newest firmware, but no changes...

Hi there,
Believe it or not i have this issue since last year and you are the only one online that i found that posted anything about this issue since then.
I've tried as well flashing all of it haha
What i've tested so far:
MIUI (global and china)
MIUI.eu (same issue)
MIUI.PRO (same issue)
Magisk or superSU (same issue)
Encrypted phone while on MIUI.eu and MIUI.PRO (same issue)
The only thing i haven't managed yet to do is downgrade the phone back to Oreo so not sure if this is a specific issue for mi mix 2 on Pie, but still i haven't found a single thread with anyone esle having this issue.
Did you maybe figure it out what is causing it??

Mine has just developed exactly the same problem. Has anyone found a workaround for this?
It originally started with fastcharge not working, only doing 250-300mah.
Someone suggested charging with the phone turned off. That's when the fastboot screen comes up. No charge entering the phone.
Unlike others, mine has an unlocked bootloader but I have never installed any roms/twrp yet.
I've had this since new

Random reboot?

So, I've had the premium for almost 3 weeks now. On the second day it crashed whilst I was listening to music +browsing in chrome. Thr screen turned inky and then turned off. Since then I haven't had anything similar happen, but I have had 1 or 2 reboots. Are these signs something could be wrong with my phone? I have like a week to get a replacement. It's rev 2, other than this I have no complaints.
Try to remove cach in recovery mode, maybe that will fix your problem. If not let me know
This has been happening to me as well and actually results in boot loops. Since I have Liveboot, I can see the dmesg output. It says "Failed to start system services. Invalid abi: ABI" or something like that. I'm RomAur so maybe that has something to do with it?
It has happened to me 3 times this week. Also RomAur 1.1. It seems to happen when i am heavy multitasking, definitely related to chrome I think.
I'm completely stock... I use chrome as my main browser. The last time it happened it froze on wake whilst it was charging... The first time I was listening to music and doing something else which I can't recall. The phone has 3gb of ram so I don't really clear my recent apps as often as I did on my S4. It happens once a week on average for me. Cache wipe didn't do anything.
You could've easily gotten a faulty device. A but load of hardware issues can do that and I would advice you to do a factory reset, update to the latest F/W (flash it if not available in ur region), see if it happens again and if it does - get a replacement
Gd luck
If you're totally stock this might not help but I narrowed my problem down to xposed being unstable as crap on mine at least. Hasn't happened since I went back to stock fw (using. 200 generic FR). But I tried to install xposed and I got the three light reboot immediately.

exactly like that on my z5 . when i flash the xposed uninstaller , it doesnt randomly reboot, but when i flash xposed , it does.i was thinking of flashing .200 ftf and then flashing xposed from the beggining (before i install any apps ) to see if it helps , but you said you did it??

No sensors/GPS with custom roms

Last weekend I flashed an old HTC One X I had lying around with This Cyanogen
After a while I noticed location services was barely working.
Using androsensor I saw that, apart from sound and battery, none of my sensors were registering anything (waiting for event, or zero), and GPS saw NO satellites at all. (Sony in at the same time saw 21)
Being my first flash, I was thinking user error, everything else was working but hey.
I tried this resurrection remix, exactly the same result
I went back to old storage layout and tried the latest cm-11 snapshot, no difference.
Since I didn't think of testing the gps & co before flashing, I wanted to try to return to stock rom. but that's not as easy as it sounds apparently.
Backups got wiped while I was trying to get my first flash, and online references and links to tools are mostly invalid now.
I tried an original recovery and locking the bootloader, but got an error running the presumably correct RRU.exem, probably due to the 1.7x HBOOT I have.
There might be a hardware issue, I opened the device to check a dicky USB connector, but don't see any damage.
Finally tried This cyanogen again no difference.
So is there anyone left here with some more experience/insight that can help me get the sensors working in custom rom, OR be able to get me back to stock, so I can test them there.
If you need any more details, just ask.

Touch screen on 5T randomly stops responding

I've been having this issue where the touchscreen on my OP 5T will be working just fine but the next second just turn unresponsive to any touch, and no amount of rebooting fixes it.
So far, I've tried using the unbricking tool and restored it to OOS 5.1.3, wiped everything off the phone and tried the latest OOS 9.0.1, and even some custom ROMs like Pixel Experience, both the official Oreo version and some unofficial Pie versions.
I even tried installing custom kernels like the blu-spark kernel and the π kernel.
But here's the thing, all of these work right after making the change but the touchscreen stops working a day later. I'm still on the fence if this is a hardware or a software issue, because (do please correct me if I am wrong) a hardware issue would be if it was totally unresponsive and not work fine after installing a new ROM/kernel, which is not the case here, leading me to assume it has to be something in the software related?

Same problem. Did you solve this problem?
Has anyone found a permanent solution to this? Or at least a reason? My op 5t also stops responding randomly to the touch. This is really bad.
I also have this problem as well. It seems that many users have this issue. OnePlus should take a close look at it
I have been having this issue for more than 6 months. The problem came after one update during android Oreo if not mistaken (Which update i can't remember)
For my phone, the screen will be unresponsive during the below occasions:
1. After rebooting the phone, touchscreen is unresponsive for up to a minute
2. When browsing pictures in gallery
3. When taking picture using portrait mode
4. When google play is updating apps
5. When google photo is backing up photos.
I am also doubting if is a hardware or software issue, because it only happened in some occasion previously for my case. Tried wipe and install stable/open beta a few times, same thing.
After the latest open beta update, it got even worst, other than the above occasions, the screen start to stop working randomly (be it watching a youtube video or using chrome), its getting annoying as i need to restart my phone a few times a day.
I saw alot of people having this issue, but has yet to raise concern of OnePlus.
I've recently had the same problem, I was still running Lineage 15.1 and had not updated my firmware in months because the official builds switched to 16, then suddenly 2 weeks ago the touch screen stops responding while I was actually using it. Reboots didn't help, clearing cache and flashing lineage didn't help. In the end I somehow got it to work again by flashing the last open beta - but even then it didn't work right after flashing it, I had to leave it over night then it mysteriously started responding again in the morning.
I've just had it happen again and I have tried removing the screen protector and completely discharging the battery as some people on the oneplus forum have reported this helps, but it did not work for me. I really can't be bothered going through the whole process of re-flashing open beta then flashing back to lineage and installing all my apps an restoring my data again, but the only other option at this point is to try take it apart to check the screen is still connected to the motherboard properly....
solution
I also faced this problem, then i tried to degrade it to android oreo, and somehow i never faced touch issue, i think this is a bug in android pie,

I'm not sure about that, the first time I had the issue appear I was still running oreo, as I mentioned, I hadn't updated anything in months due to the lineage nightlies switching to Pie.... That said, certainly seems like most people who have reported it mentioned upgrading to Pie
Facing same issue..
I have a similar issue too..
It started several months ago, when the screen used to randomly stop working, a quick hard reboot usually solved the issue.
But about a month ago, the screen stopped responding altogether and any amount of reboot did not work. So too the device to Oneplus service, there they flashed it to 9.0.7, and the screen started working again, and continued working for a few more hours, until it stopped responding again.
Tried flashing several times using the unbricking tool, but all efforts in vain.
Finally after a month or so, I bought a new phone, and today I just wanted to see if anything has changed on OP5T, and to my surprise, the touch screen started working again.
So this time I enabled USB Debugging, permanently enabled OTG, so that even if the screen stops working, I can use an external keyboard/mouse.
But OP5T is no longer my primary device, and hence I have moved on to a different manufacturer, as I saw absolutely no point in buying another Oneplus and god knows what will happen a year down the line...
Has anyone found a solution to this? I am facing the same problem with my oneplus 5T.

I was just searching this issue online. I'm currently facing it as well.
Rebooting the phone makes it go away. I face this issue while charging the phone via official dash charger.
I'm running stock Oxygen OS 5.1.7 running Oreo 8.1.0. I faced this issue 6-8 months ago as well. I cleared 7gb free space in my phone then it started working fine then. My device is 64GB variant. I never updated to Android Pie.
This is a major problem in OnePlus 5 and 5t. I've seen many posts on both XDA and official oneplus forums but found no guaranteed solution so far. I was thinking of flashing custom kernel but then saw here that people are still facing this issue in custom ROMs.
I thought I had solved the problem by installing the RenderZenith kernel, which someone on the oneplus forums recommended in the thread there dealing with this issue... but it has resurfaced after a couple of months without issue. Rebooting does not fix the issue for me, I have to flash a stock firmware, and sometimes reboot a few times, before the touchscreen starts working again. I tried installing CarbonROM instead of Lineage to see if that made a difference but it lasted about a day before the problem reoccurred. I am now going to try a Q-based ROM (probably Carbon) to see if that makes any difference, but I am not hopeful. I have even had the issue occur once while I was still running stock 9.0.9 and had not yet got to reflashing a custom ROM, had to do a full wipe and reinstall the stock ROM again to get it working.
I'm about ready to throw this phone in the bin and buy something new - only problem is I don't know what. Certainly not going to waste money on another oneplus after this debacle but there aren't many other options that are good for custom ROMs. Too bad OOS is such insecure trash and Oneplus as a company cant be trusted, otherwise I might at least see how I go running stock for a while.

No I haven't.... but I am losing faith by the minute here.... screen now stops responding even in TWRP or on a fresh install of the stock OS..... I'd say it's hardware related but seems weird that reverting to stock fixes it... sort of....

Okay. So you're currently running stock ROM version 9.0.9?
Another query, did this problem occur on your phone in stock Oxygen OS v5.1.7 with Oreo 8.1. 0?

I'm not running OOS now, but I have had the issue occur while I was. I am just re-flashing OOS to get the touchscreen to work again, but actually I can't even get the setup wizard to work once the phone boots (hangs on the "just a sec" screen), so I am usually flashing another custom ROM once the screen works again. I managed to get to about 6 hours of normal usage last night before the screen stopped responding again - after fighting with the phone all day and most times not getting much past installing magisk modules.
I am starting to think the problem is related to either Magisk, or the riru kernel hooking modules necessary for Xprivacylua (which is mandatory to install IMO) - I had been using the YAHFA module mostly but yesterday I tried Sandhook to see if it made any difference - that was when I managed to get to 6 hours instead of 30 minutes, but it was also when I went back to Magisk 19.3 instead of installing 20.2. Now that I think back, I am wondering if it was upgrading Magisk from 19.x to 20.x that made the issue resurface after a couple of months without it.... Can't remember for certain, but it seems like the most plausible explanation. I tried flashing Magisk uninstaller this time when the screen stopped, but it didn't help - only reflashing back to stock works (sometimes it even takes a few goes). Whatever the problem is, it seems like it is tripping some hardware related switch which only gets reset when installing stock FW.
the other thought I had was that perhaps the hooking framework is getting in the way - like it intercepts the screen touches before they are processed, but it bugs out for some reason and they never get passed on to the OS. I don't know enough about how it works honestly, or any idea how to go about debugging such a weird problem, so no way to look into it.
Anyway, to answer you other question - I never had the problem with OOS 5.1.7, I have never run stock OOS on my phone, but the first time I had the problem was with Lineage 15.1 Oreo 8.1.0. I can't remember if at that time I was running stock xposed or edxposed.
I'm close to my wits end here. IF the problem turns out to be magisk related, it's pretty much new phone time - I doubt even if I logged a bug report it will get looked at any time soon much less resovled, and I simply refuse to run an android phone without xprivacylua.

Edexposed is for Pie ROMS as there's been no development for Pie from official developer for xposed. Chances are you were running xposed only on Oreo 8.1.0.
Today I flashed Franco Kernel on my phone, been running smooth so far. I used to get non-responsiveness while dash charging specifically. Let's see how it goes. Will keep you updated.
Bugger it... I managed to get to 4 days or so after flashing back to LOS 16.1 / Magisk 19.3 / Edxposed YAFHA / Franco kernel, but it has just crapped out on me again.
This time I has tried a slowly-slowly approach, at first running just the stock OS and apps for a few hours, then gradually started installing magisk, riru, edexposed, then finally xprivacylua - Didn't have any problems up to there. Then I installed pico gapps, and used the Play store to do a fresh install of Mobius Final Fantasy instead of restoring from Titanium backup (this game is actually the only real reason I need gapps at all :-/). Mobius is a PITA because its like a 5Gb download, so it takes a long time to reinstall rather than restore from TB. Anyway it seemed like it was working ok for a few days after the fresh install but I just picked up the phone as couldn't unlock it. I have noticed that often the problem does occur while I am playing the game and I have wondered if there is something about it which makes it more likely to trigger, but it can't be the only thing as it happens even during the setup wizard sometimes.... bloody infuriating.
Anyway... not sure what to do now. Really CBF going through the back-to-stock dance again. Meh.

Question Soft Reboots After Every Reboot [SOLVED]

EDIT: Apparently this was a result of using the wrong setting for enabling hotspot in PropsConfig. Because all that stuff was set during bootup, deleting apps wouldn't change the situation. Setting worked fine on my Pixel XL, but not here. Changed the setting and all is well.
--------------------------
So, this is a weird issue I was curious about and may have missed on my searching. Every time I reboot the phone, when I got to log in it immediately follows up with a soft reboot. It's been happening for a while, and I'm not sure the source of the issue.
Running stock 12 ROM and rooted, but I disabled SU, modules, and Nova and am still running into the issue.
Might be quicker and easier to back up your required files and just factory reset.

I know, it's just that it sounds like you've already disabled some things that could be causing it, which hasn't helped. If it was me, with something like constant reboots, I'd want to start fresh just to make sure they are eliminated for good

I've seen reports of "random" (=not intentional) reboots after
+ booting up the phone
+ using the FP scanner
+ making videos or shooting photo
+ doing a firmware update (I've seen both reports of ppl that "officially" OTAed & used manual flashing)
+ doing nothing
+ doing something
Some were able to fix their issues by factory resetting, some needed replacement devices. Some reported that even after a factory reset, the issue still persisted, but they were able to fix it by NOT using a backup via cable, some reported that even the Google Drive backup "corrupted" their phone (fix after setting up everything by hand from scratch). Some even reported their issues to get fixed via a software update.
So it seems to be connected to hardware (= replacement device) and/or software simultaneously (=fix via reset).
Strange this is since there are also numerous reports of Samsung owners that upgraded to A12 about random reboots. So it might even be something Android 12 related, or it's just Samsung also implementing similar bugs without it being A12 related (unlikely, since the reports seem to be centered around people using the new A12 update).
I also had the random reboot problem (~ 6 times a day, when doing nothing, it just rebooted when the phone layed on the table in idle). I wasn't able to fix it via a reset, so I got a replacement device.
I also have the "random" reboot problem on my Pixel 3 since upgrading to Android 12 (never had any issues all the years I've been using that phone), so that issue is clearly caused by A12, but I haven't troubleshot it/ tried to solve it, since I don't actively use the phone currently.
Aside from trying a factory reset and minding the backup issue (especially backups that you got from phones that did NOT have Android 12), there is not much more that you can do (ofc you could also use the Pixel repair/android flash tool to do a "clean" install of Android on your phone). Next step would be to contact Google.

How To Guide For those who are experiencing "phone freezes at charge" issue

First I thought the phone freezed everytime I plug in the original cable + 33W brick, but it was not that. The issue just appeared when the charging cycle count shows negative value (believe it or not, it was about -4 MILLION in my case, that was insane, you can find in the Battery Settings section with crDroid rom, I haven't checked on other roms). I asked on the Telegram crDroid channel and found out that many ones got negative value but they just told me to ignore it. I believed that something was wrong with the power management so I had done a workaround by changing the original cable to another one (a redmi note 7 cable). Once I plugged the phone in with that, the charging cycle count value was back to normal (it was about 34-35 that time). And then I switched back to the original cable, and booooommm, it worked, the phone was charging fast ( about 5000mA, 23W)!!
I'm no tech expert to know what exactly happened to those custom roms but I think it could help devs tracking the issue.
A guy on Telegram crDroid channel (https://t.me/crdroidf3) told me that I should try to boot to bootloader then reboot back to normal system to avoid getting negative charging cycle count, or flash the 13.0.3 EU firmware but I haven't tried yet. You can do it if you want to.
have same problem on custom rom freeze with 33w... miui works. 12.5.6.. old version like miui global 12.0.5 eea freeze
any fix?
i notice one thing maybe my phone is new unit already born with 12.5
if i flash stock kernel miui in custom rom i lose wifi data signal due to incompatibility but 33w charge works
so i think is kernel issue compatibility
i want to use cr 11 i flash custom kernel same prob
