1. Background
It's been 4 months since I bought Xiaomi K20 8G and 256G(Not Pro). I bought it from China, and from the beginning, the cell phone was unlocked. (I didn't know what it was. Maybe the seller changed the Chinese version to Global Rom and sold it. I didn't even know what that meant at the time. I think seller stated the same.)
2. Problem
There was a bit of heat from the beginning. And I got many messages that due to heat warning, the Wifi, camera, and 3G/4G would be limited. In relation to that, I found out that there had been a lot of such problems while searching solution in Internet, and I saw many articles, software upgrades had solved such overheating. And someone recommend such thing can be solved by installing ROM again in the setup(there is menu downloading latest ROM). So I tried this (MIUI 11.0.4 global) and further deleted many apps and re-installed apps, used battery saver mode and etc.. Though there was heat, phone didn't give a overheating message, and wifi also worked well.
For the time being around 1 month, I used it well.
Just 4~5 days ago, again overheating message came. Then new ROM (11.0.5) came and phone got hang / shut down / reboot / Overheaing warning / wifi disconnected.(WIFI is on, but suddenly not working. Then I off WIFI, tried to on WIFI but it didn't ON. Toggle button move but come back off position again, Once I reboot, it work for some time only.)
3. Attempts to resolve
Although phone has heat, I decided to install TWRP & the other operating system (ROM) because I thought such problem coming from the operating system / software / apps rather than a hardware problem.
I've been working hard on installation of Pixel Experience following the guide of the experts, but the above problems persist, I've changed Global Rom to EU Rom, I've tried downgrading from the recently updated MUIU.
However reboots occur more and more frequently.
Even though I don't do anything, my K20/9T phone is rebooting, hanging, stopping, and shutting down. And even no tasks are there, heat is on the phone.
4. Request.
Experts, please help & guide me.
I'm under huge stress from K20/9T.
I am trying to drain out battery.... at this moment.
LOL just fu cking trash your phone and buy the pro one
You should try xiaomi.eu ROMs.

Hi guys.
I'm here to share a problem I'm having with my Nexus 6P: it often gives a crash randomly, needing to be restarted by force.
This does not happen because of a specific app and sometimes happens even at boot , when Google logo still not appeared.
I already using the phone about two weeks.
I received him with rom stock 6.0.1 and had the upgrade to Nougat available.
I thought the upgrade to 7.0 would correct the problem, but it was not what happened.
From the update I also felt that the crashes were more frequent when the battery was at a very low level, between 20 and 15% (as commented in a reddit threat that I can't copy here).
Following some recommendations that I found , I formatted the Nexus 6P with the factory settings to see if the problem returned.
Yes, it happened again.
I formated again and was gradually installing my apps to check if it was not a specific app.
I did it at last three times.
On these occasions, apps like Google Keep, Duolingo, ES File Explorer, Google Fit, Podcast Republic and even the Play Store gave the crash.
I formatted again and installed each app one by one again to try to identify a culprit and had the same results.
To try to work around the problem, I decided to go for a clean install of the entire OS with the latest build using the SDK (adb and fastboot).
Even with the flash of the latest build I continued to have this crash problem.
So I decided to go for custom roms.
I installed Pure Nexus and Sinless, and continued having problems with crash.
I tried to install the CyanogenMod, but failed. After flashing the rom, GAPPS and vendor image, the device crash in the Google logo.
My last attempt was to go deeper and replace the kernel as well.
I installed ElementalX (7.0) and Pure Nexus as ROM.
In the beginning, I still had many crashes, so decided to make some changes in the kernel ElementalX.
In a desperate attempt, I decreased the CPU clock all to minimum (1248 MHz).
Interestingly the crashes started to occour less frequently, but they still happen randomly and unexpectedly.
I have no idea if this reduction in CPU speed had any effect or was placebo.
What matters is that I'm still having crashes and I wonder if anyone has any idea of this solution to my problem.
Thank you guys!
PS.: the return of the phone is not an option. I'm in Brazil.
PS2.: sorry for my bad english.
Wow you have exhausted every idea... Return sounds like all that's left unless you wanna try putting the phone in the oven to see if it's just bad solder.

I'm thinking you've got some damaged or corrupted internal storage there.

Don't mean to scare you, but that is exactly what was happening to me right before going into an unrecoverable bootloop. Nothing I tried revived the device, although there have been some that have been able to. I ended up RMA'ing my device as nothing I did brought it back to life. You might be in a different situation but just giving you a heads up.
*Bump*
Stock 7.1.1 and rooted here. I've been on the official 7.1.1 release for our 6P's since early December, and for the past week or so, I've been experiencing freezing as well. I'd be in the middle of typing in Hangouts, streaming music in the car via bluetooth and Spotify, or just waking the phone up from sleep. For the past few days, I've been getting 3-4 freezes per day.
On rare occasions, I've left the phone alone to settle, and it returns to normal, but more times than not, a hard reset is the only 'fix'; until the next freeze.
I reluctantly wiped the phone, unrooted, flashed stock 7.1.1 and re-rooted all via NRT last night. The phone froze again this morning coming off the charger...
Granted, it decided to restore 528mb's worth of WhatsApp history as soon as I unplugged it (why it didn't restore on charger overnight is beyond me though). Will update if it freezes again.
The phone runs butter smooth with zero issues other than these freezing occurrences though. MO, the 6P is the best all-rounded phone currently available, even if it's a year old already.
Appreciate any help or suggestions!!
That's odd try ex kernel and over clock or try HEBF manager on play store
Quick update. Couldn't bear the multiple freezes per day, so I called Google to ask for help. Apparently I've done everything I can on my end (including a factory reset and updating to the latest firmware), so they sent out a replacement 6P to me free of charge. They'll also be covering the courier/shipping costs for my old 6P too. Fantastic customer service. Kudos to them!! I called them Tuesday morning (20th Dec) Australian time, and received my replacement 6P Friday afternoon (23rd Dec). Very quick indeed
Half a day after setting up my replacement 6P, including updating to 7.1.1, I started getting the same symptoms as my old 6P. Freezing, unresponsiveness, etc. Persisted for another day and had enough. I've since done a full wipe and downgraded back to the final 6.0.1 release, and it's been stable as a rock for 3 days now. No freezes, lagginess, nothing.
So I deduce it might actually be a software issue with 7.1.1, and not a hardware problem. It appears a growing number of Pixel and Pixel XL users are also experiencing random freezes on their new phones running 7.1.1 too...
Looks like I'll stick with 6.0.1 until Google makes a formal announcement and something is done about 7.1.1. I've missed Xposed and GravityBox too, so 6.0.1 is all good. Most importantly, it's stable
Had you ever tried booting into safe mode to see if maybe an app was causing the issue? Maybe a compatibility issue between an installed app(s) and 7.1.1

Thanks for the pro tip. I did consider doing that with the replacement 6P, but the only apps that I had installed were the stock Google ones that came with 7.1.1, WhatsApp, Facebook, Twitter, Instagram and SwiftKey. I just assumed if such popular apps were the cause, a lot more people would have pinpointed them as the problem?
I did however read a few users claiming SwiftKey to be the culprit prior to RMA'ing my old device, but even after uninstalling that from my old phone, I was still getting the freezing issues.
Hello to everyone,
I am a new forum user even if I follow you by many years.
A few months ago I bought a Axon 7 (A2017G) and since then I've encountered software and hardware issues.
In particular, I upgraded to Nougat (versions 7 and 7.1.1) and I have experiencing loss of data connection and phone line. A simple restart of the terminal has always solved everything.
The fingerprint reader is no longer responsive as before and the camera focus has worsened significantly. I tried to make, several times, a factory reset but it did not do anything.
So I decided to return to marshmallow (B10).
The other problem is display related.
Everything is more clear when using the virtual keyboard. In practice, it is as if the display were disturbed, for a fraction of a second, by a sort of electric discharges. The phone works normally but it were annoying me a lot.
I have already taken steps to replace the device but nothing has changed. Which is your advise except to make a return of the phone?
Sorry for my english.
Hello,I am currently using redmi note 7. 3/32 gb variant and using pixel experience latest update & magisk installed.from past 2 days i am facing very quick charging and quick discharging issue. Also when i am opening some apps like facebook or youtube for example i am facing automatic restarts.i am not able to use my mobile.
Everytime when there is an incoming call it restarts and i am not able to figure out who is calling me.I tried restarting many times,Tried resetting my mobile and also clean install old version of pixel experience and also clean flashing latest pixel experience rom but no use. Should i go back to stock rom ? Or can it be a battery issue? I bought this phone on may 2019 so just 1 year had been completed.
UP. same issue here . Did you find a solution already ts?
The problem arose in the first week of January.
Then I have done necessary criteria to have a custom rom.
But the roms failed to work properly in my phone. Mostly, with every rom, the SOUND was not working,
Then I have installed PE 10 PLUS, and it worked fluently without an issue.
But recently, with the PE 10 PLUS rom, the phone started to misbehave again and the apps are showing errors time to time
like, " X app is not responding", "SYSTEM UI ISN'T RESPONDING" .
And the phone freezes and gets restarted.
I don't think there is a sound IC issue, because, with PE rom, the sound was perfect.. So, what can be the issue and what i have to do?

Hey, I have the same issue with accessing mic speaker and sometimes camera too... I thought it's some IC issue. Let me know if any ROM gets around this issue

Hi there. I used PE 10+ after facing the issue. Around one month, it was okay, but after the month, it started the same issue again, saying, "System UI IS NOT RESPONDING" then everything became unable to use.
Testing many roms, I found Evolution UI latest version working. please be noted, the roms has several bugs and SOT is lesser than the roms I used before.
