[Xiaomi Mi A2 / 6X Questions & Answers] Ravenlll:
Did you check battery consumption at this time? Some users report that when CPU stuck power consumption goes up (it's normal), but when you change frequency in kernel auditor back to normal, power consumption remain as the cores run at max frequency. I cannot check this because my device is not rooted, but I read this on miui forum about week ago.
[Xiaomi Mi A2 / 6X Questions & Answers] e34v8:
Can't really say what is the consumption at a specific moment. All I can say is that the phone runs cooler than when it's with stuck cores. My SOT is around 5+ hours, but I use the screen at high brightness and that is my main consumer.
[Xiaomi Mi A2 / 6X Questions & Answers] S /\ E E D:
Guys do you think this problem is deal breaker?

I sold my mi a2 lite because of screen dead pixel and ordered mi a2, should i cancel my order?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Depends. Even with the bug I have a better battery life than on other devices. The best thing you should do is to try it out. Maybe you get a device without the bug.
[Xiaomi Mi A2 / 6X Questions & Answers] Lurensu:
To me yes it is, but luckily it's very easy to solve.

It's just disappointing to see the total lack of support by xiaomi
[Xiaomi Mi A2 / 6X Questions & Answers] e34v8:
Agreed. And this is supposed to be one of the selling points of the device. Android One - fast updates and support.

And I remember how at the announcement, google and Xiaomi siad that they have tested the battery life in all situations. They tested nothing it seems.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
Has anyone tested the Beta ROM to see if the processor bug has been resolved?
[Xiaomi Mi A2 / 6X Questions & Answers] tianma163:
when I stoped use fingerprint, CPU is ok.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
mine too, but sometimes the bug come back and i need restart the phone
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
It's not the fault of the fingerprint scanner!

"If an application demands a ramp to maximum clockspeed (by placing 100% load on the CPU), a user can execute another task before the governor starts reducing CPU frequency.

...

Interactive also makes the assumption that a user turning the screen on will shortly be followed by the user interacting with some application on their device. Because of this, screen on triggers a ramp to maximum clockspeed."

They just f-up the software and that is the reason why the CPU don't lower the frequency.

Everytime I charge my phone with rapid charge the frequency of my CPU goes up and gets stuck.

You can also get the bug if you let run some CPU intense benchmarks over time.

Even if you use the camera app and make some photos with HDR it is possible that your phone gets the bug.

Everything that max out the CPU is a possible bug trigger. The Goodix fingerprint pushes all CPU cores to the max and that is why people think it is the fingerprint scanner because the most people are using it.

But it's just like how the CPU governor works.

My guess is that the timer keeps going or that another process triggers the timer again so that the CPU stays on 100% load all the time.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
And why do people with the FPC sensor do not have this bug?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
First of all: Wrong even people with the other sensor are reporting the bug.

Second: Other sensor means other driver = terminate the possibility of a driver issue.

Third: Different production line.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
I do not think people with the other sensor have this bug, dozens have already said they do not have
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Maybe you should read the entire thread and the official Xiaomi Forum ;)
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
Most people who have FPC do not have the bug. And some may be on time charger or something.
[Xiaomi Mi A2 / 6X Questions & Answers] phobox360:
Just a little addition to this issue, I'm currently on the September update and after first updating I did experience the bug however after a reboot and some digging it's now been three days and no sign of the bug returning. This is with the fingerprint enabled, Goodix sensor.

My digging consisted of going through the services list in Developer Options and disabling a few oddities, namely two services called Spock and Fingerpirnt Test (spelt that way, oddly). I also disabled a system app called PAI and have uninstalled Mi Store and Mi Community, both of which are hidden apps not available from the launcher.

So far, so good. I check daily for the bug using CPU-Z and I use the fingerprint everyday to unlock the phone too. Will update if it ever returns.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
i tried this here and and bug came back after 5 minutes
[Xiaomi Mi A2 / 6X Questions & Answers] Lurensu:
I don't think so. If you manually set the frequencies, even with the interactive governor, they stay normal.
[Xiaomi Mi A2 / 6X Questions & Answers] phobox360:
There may indeed be a quirk of the interactive governor, I have seen similar weird sticking bugs on my old Galaxy S4 using the Interactive governor on various kernels. Changing the governor to something else and back again usually fixed it. So I doubt this is a hardware issue, I think it's kernel related.
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Yes because the cores can't reach the max frequency anymore because the user manually lowered it.

---------- Post added at 05:05 AM ---------- Previous post was at 05:02 AM ----------

Yes and if it would be an hardware issue you would get the bug everytime you touch the fingerprint scanner.

I tested it at least 50 times and never got the bug but if I charge my phone I get the bug 9/10 times.

And the CPU can't be broken because if it would be broken the other users who underclocked / changed the governor would still have the bug but they don't have it.

---------- Post added at 05:13 AM ---------- Previous post was at 05:05 AM ----------

Spock: Data collection service - reports to Xiaomi

PAI: App-Sideload for preinstalled apps like Google apps, mi feedback, IR blaster etc.

Fingerprint test: is for software testing of the fingerprint sensor and also can included additional drivers for your fingerprint scanner. DO NOT UNINSTALL!
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
they will fix it?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
That is the question. Xiaomi has an awful device support. So I would wait for the October update if the bug is still there I will definitely buy another phone.
[Xiaomi Mi A2 / 6X Questions & Answers] phobox360:
PAI and Spock, as you note, are Xaiomi related tools and are not necessary for normal operation of the device, so I've disabled both. Having been using the device for days now, including use of the fingerprint, with Fingerprint Test disabled I've not encountered any issues. The fact it's spelt wrong in the services list also leads me to believe it isn't essential.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
what date is october update?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
October the 5th normally.

Pixel devices getting the update on the 1st.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
do u really think they will fix it october 5?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
As I said: If not I will buy another phone.

We will see.
[Xiaomi Mi A2 / 6X Questions & Answers] OverTheEdge:
I have the r10p4 and no cpu stuck issue.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
i have t10p4 and i have the bug
[Xiaomi Mi A2 / 6X Questions & Answers] OverTheEdge:
Did you patch the Sept update already? If so then this issue is weird.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
yes, i have the last update, and u?
[Xiaomi Mi A2 / 6X Questions & Answers] OverTheEdge:
Updated it too. I just got my phone last Monday. The Sept update was big around 1.1gb.
[Xiaomi Mi A2 / 6X Questions & Answers] Lurensu:
No, you didn't understand. You have to manually set the MINIMUM frequency, not the maximum one. The minimum is what get stuck causing the bug, so changing it back to normal just gives you a normal device with a good scaling processor in the whole range.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
u processor dont get stuck anymore and u have the fingerprint working?
[Xiaomi Mi A2 / 6X Questions & Answers] e34v8:
That's not true. We lower the minimum frequencie not the maximum. I'm using interactive and my cores still go to max frequencies when needed. The problem is not the governor and how it works. The problem is that something is modifying the minimum cpu frequencies and setting them to their max values. Once I lower the minimum frequencies back to their normal values, all is fine and stays fine, no matter what I use my phone for. No underclocking of the max frequencies needed.

Xiaomi's dev team have all the data needed. I don't know what's taking so long.
[Xiaomi Mi A2 / 6X Questions & Answers] Lurensu:
Exactly this

---------- Post added at 09:03 AM ---------- Previous post was at 09:02 AM ----------

Yes
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Than the "fix" doesn't make sense.

If something modifies the minimum frequency to the max frequency than it would also happen with the manually changed minimum frequency.
[Xiaomi Mi A2 / 6X Questions & Answers] Lurensu:
Yeah in theory, but in practise it doesn't happen, we don't know why
[Xiaomi Mi A2 / 6X Questions & Answers] e34v8:
It doesn't. Don't know why but it doesn't.
[Xiaomi Mi A2 / 6X Questions & Answers] Benjamin_L:
No. First Monday in the new month is when Google releases the updates and factory images
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
For Pixel devices. All other OEM are releasing on the 5th.View attachment 4607556
[Xiaomi Mi A2 / 6X Questions & Answers] Benjamin_L:
Sure. All other oems release whenever they are ready..

Also the date is quite arbitrary. It only makes a difference about which cve's have been fixed. Code is available way before the update internally of course. Something around two weeks before releasing
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
We are talking about the OTA Patch for me Mi A2 Android this will be available at the 5th!

This is not a fricking Google Pixel thread!
[Xiaomi Mi A2 / 6X Questions & Answers] Benjamin_L:
You were talking about pixel devices getting it on the 1st which is simply not true. Also no one knows if we always get the OTA on the 5th. Xiaomi is not known for fast updates. Let's hope the A2 will be better. Your screenshot btw does not show the release date, only the date of the security patch level which is alwys set to 5th of a month for the second round of the bugfixes. The code is not released on the 5th as I said, but much earlier to give oems the time to implement it.

[Xiaomi Mi A2 / 6X Questions & Answers] Reptant:
Got the bug in 126/6 version with goodix fp

For now, it seems the sole contributor to this bug is the fp. Rebooting the devices fixes it for some time, but it eventually reappears (way of unlocking phone doesn't matter eventually)

Having read multiple threads about this, it seems that setting the minimum freq solves the issue, but i have to test whether the setting remains, or gets changed in runtime

Will have fp disabled until October patch (hopefully soon..). If the bug is not fixed at the next patch, more measures need to be taken..
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:

An Indian who is part of the group of beta testers showed the history of conversations that the developers do not even consider this a bug
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Okay Proof it please. Link/screenshot. Would be a great information for ALL who have the bug!
[Xiaomi Mi A2 / 6X Questions & Answers] Ravenlll:
A guy on another forum reports that if he start carry phone, frequency stuck more frequent. After this he make some test: he reboot phone, lock it and wait it goes to deep sleep, then touch sensor with rug (simulate like it's in pocket) and then unlock with finger. I tried this and both times a can reproduce the bug (took about 5 minutes). So if developers need to trigger the bug, they just need to do this a little bit weird steps. The problem is they even don't care about this, and not confirm this as a bug in beta testers group. They said "how can we trust cpu-z".

---------- Post added at 03:47 PM ---------- Previous post was at 03:43 PM ----------

A have a screenshot but the problem is the guy who send me this will be kicked from testers group. It is true that what set say maximum was: "ok, let's check how it comes".
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
I can not put the proof because the guy would be kicked out of the group, but rest assured, they will not fix the bug in October, maybe in November with luck
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Can you PM me the screenshot? I need proof of that. Because if it's true I will immediately buy another phone and will never touch a Xiaomi Phone again.
[Xiaomi Mi A2 / 6X Questions & Answers] Ravenlll:
I cannot PM to you, due to respect to this guy that say this to me, we both saying same thing with juninhoak. It's up to you believe to this or not. On russian speaking subforum miui on Redmi Note 5 they confirm this bug, and said that sended to the developers. So, if fix comes to Redmi Note 5 I think it will be applied to our phones also
[Xiaomi Mi A2 / 6X Questions & Answers] bartoloandre98:
No, I am not stupid, thank you for asking.
[Xiaomi Mi A2 / 6X Questions & Answers] Reptant:
Hopefully it will be fixed.. Atleast in the android pie update

Even if not, the development community will grow and provide a fix via a custom rom/kernel

Its a shame, cause after disabling fp I'm at 70% with 3 hours SOT
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
But for the normal user flashing/rooting is not an option. They just want a phone that works and in the current state it doesn't. If they are not fixing it that means that they are basically lying to the customers and don't provide support for these devices.

This will be my last Xiaomi device. I don't support a company who don't support there phone in the right way.

And also my battery life right nowView attachment 4608508
[Xiaomi Mi A2 / 6X Questions & Answers] Reptant:
I just moved from my oneplus one after 4 years of modding and wanted a a chance to move from that life..

Well ofc it's a problem for the common user, but even for someone used to rooting/modding, constantly monitoring your cpu stats is not the most pleasant experience

Any report of any 6ram 128gb with goodix fp and with the bug?
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
+1 Mi A2 with the Goodix sensor getting the bug. Disabled the fingerprint scanner about 3 days ago and the bug didn't happen again, getting 6-7h SOT now, against 3-4h SOT with the SD660 stuck in max frequency, about 40-45% increase. The battery easily lasts me 2 full days without the bug.

I did play a lot of games, took many HDR photos, ran some benchmarks and the CPU didn't get stuck again, but if I use the fingerprint scanner, after around the 5th or 6th unlock the SD660 locks on the max frequency.

Updated to the latest September security patch. Hoping for a fix since I just bought this phone.
[Xiaomi Mi A2 / 6X Questions & Answers] juninhoak:
they will not fix in october patch
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Jesus. This phone is so useless.

Rebooted my phone, opened Aida64, touched the fp sensor, got the bug.

So you still can get the bug with an unlocked phone xD

I'm happy that I bought a new phone.
[Xiaomi Mi A2 / 6X Questions & Answers] mark.dx:
I have the exact situation with you. Not using FP and easily 2 days battery life. Its so unfortunate that I really like this phone especially for the camera.
[Xiaomi Mi A2 / 6X Questions & Answers] Ravenlll:
Accidentally I find, that removing fingerprints not disabling a fingerprints sensor. To check this, unlock the phone, wait for a while, until the screen become darker (it means the phone intended to go sleep), then touch fingerprint sensor. The screen become bright again and the phone wakes up. It explains why even if you remove fingerprints the sensor is still alive and the bug occurs anyway, but later.

Some other guy said, that he has FPC, and this trick not works for him. Guys, can you confirm? Maybe it's related to the gestures, because in driver code I saw some parts of code related to this. This can be a part where bug occurs because of this difference in drivers.
[Xiaomi Mi A2 / 6X Questions & Answers] Grodly:
I can confirm this on my unit aswell, w Goodix. I have removed my fingerprints 5 days ago and have not triggered the bug yet.

If I'm touching FP reader just when it goes darker the screen lighten up again.
[Xiaomi Mi A2 / 6X Questions & Answers] Ravenlll:
Looks like they today asked in beta testers group more logs about this issue. I hope they just debug this bug and collect logs from users, analyze, and will release fix in the next beta. Someone who is in beta testers group or has friends, can you please confirm guys?
[Xiaomi Mi A2 / 6X Questions & Answers] SirMorokei:
Didn't hear about that. Last standpoint was that it isn't a bug and they don't trust apps like cpu-z/Aida64.

But tbh I don't care anymore. I will return my phone as soon as I have my new phone. And I will never ever buy a Xiaomi Phone again. Screw this garbage company. The focus of Xiaomi is to make and sell as many phones as possible and don't support them.
