It acts normal after reboot.check it again after sometime
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
I unlocked bootloader + Rooted device last night and changed the 'scaling governor' to 'ondemand' and the issue is gone! :D
[Xiaomi Mi A2 / 6X Questions & Answers] AhanafTanvir:
You are getting better battery now right?
[Xiaomi Mi A2 / 6X Questions & Answers] pack21:
Mine 4/64 A2 is also stuck in the maximum frequencies, if i reboot the A2 the 8 cores go up and down normal, but after some time of use, it returns to jam in the maximum values.

Should i return A2, is it a hardware or software problem?

4 hours of SoT

:(
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
Its kinda early to tell but yes! Almost no drain overnight, and currently in 2h SoT = 70% battery left.

I think its a software/kernel issue, not hardware. Because I changed the 'scaling governor' and the issue is gone...
[Xiaomi Mi A2 / 6X Questions & Answers] pack21:
If i bootloader and root the A2, can i reverse the process, or lose the warranty forever?
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
I honestly dont know... And I dont care because Xiaomi is not officially in my country... So I dont have warranty or anything anyway..

Edit : nvm mine is stuck aswell
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
and update

I checked my cpu-z today after lunch and I saw (again) every clock speed on max. (and I've rooted the device and changed the scaling governor already to 'ondemand').

So I opened kernel auditor and it was showing that every other frequency was never used, only the max one (2208mhzx1843mhz). So I went to the CPU tab and the conf was like this:

Big frequencies:

cpu maximum frequency = 2208Mhz

cpu minimum frequency = 2208Mhz

LITTLE frequencies:

cpu maximum frequency = 1843Mhz

cpu minimum frequency = 1843Mhz

And it was not like this yesterday. Something changed that configuration... I had to manually set the max and minimum, and it became operating normally after that.

So basically, only changing the ondemand was not enought, apparently.. :(
[Xiaomi Mi A2 / 6X Questions & Answers] matrox1m:
I have the same issue. I noticed that if I change the sim from one slot to the other it happens a lot less but I still have to monitor CPU and restart at least once a day....it's getting frustrating.

And also, phone app uses a lot of battery, 40% drain after 3 hours of talking ( Bluetooth headphones or normal)
[Xiaomi Mi A2 / 6X Questions & Answers] pack21:
I did the trick yesterday and didn't have any problem, all cores work between high and low frequencies. I went from 4 hours SoT to 6 Hours.

i made check box, for apply on any reboot, dont know if you do the same.
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
Yes I've also applied on boot... Now I'm trying the 'conservative' scaling option to see how it goes...

Try not restarting the phone and watch daily if the cpu cores get stuck... Did you change only the governor?

Thanks
[Xiaomi Mi A2 / 6X Questions & Answers] pack21:
Yes, I observed all day, and the 8 cores always working, as you can see in the above,iI just changed the governor parameter of the big and small cores, and check box of boot apply.

6 hours of SoT without any stress and lag.
[Xiaomi Mi A2 / 6X Questions & Answers] ojetepicor:
I don't think the scaling governor mode is causing this fast battery draining. I've also got a Mi A1 which its scaling governor is also set to interactive and haven't got that stuck cores freq.

Returned to seller while the issue is fixed and back to A1.
[Xiaomi Mi A2 / 6X Questions & Answers] hugopg:
I'm probably the Kernel fault. An software update could fix the issue... No need to return the phone to the seller..
[Xiaomi Mi A2 / 6X Questions & Answers] lordkelvinx:
Since from beginning I thought that it's something to change only with future update.

The bug thread in the MIUI Forum it's today the most confirmed off all. If continues that way, it's sure that Xiaomi/Google will pay attention in this.

Xiaomi Mi A2 Users Complain to the Battery Problem Considered to be Occurred with an Interesting Error

Users of Xiaomi Mi A2 are uncomfortable with their batteries running out quickly due to an error that is thought to be caused by a fingerprint recognition sensor.

Google's Android One program has shown great improvement over the years. It is possible to say that the first version of the program looks like the Android Go program. Android One turned into a brand that offers consistent usage experiences while offering manufacturers the opportunity to customize their devices. For Xiaomi Mi A2 users, this has caused things not to work out due to an unrelated error.

What is certain is that some people are faced with the problem of rapid exhaustion of the battery. The cause of the problem is that all processors are shown to work at the highest level of simultaneous and permanent operation, yet it is not known what caused it. The general idea is that the problem of battery exhaustion is related to the fingerprint sensor. Nevertheless, some users continue to experience battery failure even though they have removed the fingerprint sensor.

￼

The problem persists even if users temporarily resolve the problem with the processors to the highest level by restarting the device every two hours. Some users claim that the problem is caused by Google Play services and application data should be deleted. Although at least one person has tried the method, it is known that his problem has not been solved. Opening the trial bootloader was done by setting up the phone, deleting it again and reinstalling the bootlader. Nevertheless, after a while, the same battery problems started again.

I can confirm the 1401 Mhz little cluster bug with 2 october update.

Ps:it's random,and i faced it the first day i applied the update since then when checking, the CPU was always on 633 mhz.

Today when checking Devcheck,the bug is present.

A reboot fix the issue.

we have an google thread about this issue (1401mhz stuck)? https://issuetracker.google.com/issues/118276433
[Xiaomi Mi A2 / 6X Questions & Answers] ascii7:
I just got myself a Mi A2 (64 GB, with sensor from FPC) and received one big update to 9.6.15 (2nd October update). Since then I noticed the 1401 MHz bug sometimes and rebooting the phone fixed it temporarily. The next day I unlocked the bootloader, which triggered a data wipe, and haven't seen this bug anymore. I'm not sure it's related, but those that are having the bug already tried a data wipe?

In the other hand I'm now having the empty Smart Lock window bug. I don't use it for now so it doesn't bother me too much...
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:

[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
No. It is not a hardware problem. No. No. No. No. No.

just because a custom rom still has the problem doesnt mean its a hardware problem. Its a driver problem between the CPU and the FP sensor, qualcomm sent Xiaomi a fix for it and the 2nd october update fixed it for GOODIX sensor users. They havent fixed it for FPC sensor users, i think theyre not even aware of that bug yet

I'm not sure. But the only people I see reporting that their bug is still not fixed is FPC users.
[Xiaomi Mi A2 / 6X Questions & Answers] lordkelvinx:
Someone with the FPC sensor needs to run tests and find out if the problem is persistent and where it comes from, whether the source is the same as it was causing on Goodix or not.
[Xiaomi Mi A2 / 6X Questions & Answers] ttretter:
I have FPC sensor and I don't have this problem at all. Don't think this is related to the fingerprint sensor.
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:
I think that too,

But i do have the 1401Mhz little core bug,it's random and can't find a way to reproduce it, for now.

what is certain,is that the bug was introduced with October update.

[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
The smart lock bug is easy to fix. But that's a general oreo bug. Its triggered by having non English languages on gboard or system.

Tell me about your 1401 bug. After the data wipe it hasnt happened again? I data wiped right after the October patch and relocked bootloader and had it happen like 4 or 5 days later

---------- Post added at 04:40 PM ---------- Previous post was at 04:14 PM ----------

What do you mean on and off the bootloader? Do you mean unlock and lock?
[Xiaomi Mi A2 / 6X Questions & Answers] strapabiro:
Hei is that "easy fix" permanent or just the disable reboot enable can't even call it a workaround thingy?
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
If I had to guess, some app is triggering this. Doesn't make sense that it takes days for it to kick in. Some people had it the first day after the 2nd October update, while I had it only after 5 days.

Do you use stock launcher?

---------- Post added at 02:58 AM ---------- Previous post was at 02:26 AM ----------

If becomes permanent with the Language thing
[Xiaomi Mi A2 / 6X Questions & Answers] strapabiro:
I don't understand, can you elaborate please?
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
Might be some process of some app getting stuck in a loop in the background, hence why the cpu stays at 1401mhz.ive used it all day today without the bug. I went 5 days without having it prior to that. So maybe a certain app is triggering this bug. SOMETHING has to trigger it, or else it wouldn't go days without having the bug. Also explains why only some people have the 1401 bug and some don't.

It's just my hypothesis
[Xiaomi Mi A2 / 6X Questions & Answers] strapabiro:
Dude you state in two posts above that the smartlock can be easily fixed. Is that "fix" PERMANENT or is that disable smartlock-reboot-enable smartlock whatever ???
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:
There is no permanent fix for this as of now,it's an Oreo bug, and is present with others phones running Oreo,too.

---------- Post added at 09:49 AM ---------- Previous post was at 09:43 AM ----------

Yes.

I too,got it immediately after rebooting the 2nd October update, i didn't add any new apps to my list, so i'm not sure if the cause is an app! and i can't reproduce it.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
I managed to get it to stay after reboots. Do you speak more than one language? Do you have your language set to anything other than English? That triggers the bug. I read that on reddit and verified it. I had a blank screen in smart lock settings and smart lock wasn't wasn't working. I deleted my other languages on both system and gboard and wools! Without even rebooting, smart lock was working again
[Xiaomi Mi A2 / 6X Questions & Answers] strapabiro:
Hmmm, thanks for the heads up, gboard is set to two more languages near English but I will not delete it I rather use as it is ... Systemwise everything is set to English.

Now I see that smartlock is broken because of this between phone and chromebook also.

I hope ppl are getting fired because of this at Google.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
Whats weird is some people get the bug and others don't, regardless of what FP sensor they have. So if if everyone has the same hardware, it has to be some setting or app we have. Or else everybody would get it. Maybe a 3rd party launcher? Im gonna go back to stock launcher
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:
I'm using everything stock, no modifications,and stock launcher.

I doubt,I think the bug is present but they didn't test well.
[Xiaomi Mi A2 / 6X Questions & Answers] MarXDroid:
Hello, so after V9.6.15.0 I have this problem, frequency is locked at 1.8Ghz, everything is laggy, apps sometime crash and system android is the first one in battery usage. I dont have any modifications, no root, locked bootloader, stock ROM. I also tried to disable fp sensor and it didnt help (i dont have goodix fp), reboot phone multiply, after restart its good for few minutes and then it starts again. Im desperate and I regret, that I buy this phone. No more Xiaomi for me probably... :/

EDIT: Also battery life is very bad, I have to charge twice a day, SOT is like 2 hours, sometimes less.
[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:
Should be locked to 1401 Mhz!

There is no lags or crash,just that damn frequency bug!

Listen,it's always like that with a new phone, look for e.g all the drama with the Pixel 3/3XL (a 1000 $ phone).

What i don't like is the lack of communication from Xiaomi...

[Xiaomi Mi A2 / 6X Questions & Answers] alfat696:
in redmi note 5 ai latest dev solved this issue
[Xiaomi Mi A2 / 6X Questions & Answers] Lunatiic:
In your case It doesn't look like the CPU is actually locked. Since your device is slow and crashing, It could mean that something is hogging the low power cluster and, as a consequence, the frequency is at 1800Mhz. It could be an app, or a part of the system. Try to check If there is something using the CPU and, If there is, and It is uninstallable, uninstall It. If it's not, try a factory reset.

I've been using my phone since the second october update arrived without rebooting It since then and the CPU still didn't Lock up, even though I'm using the FP constantly.
[Xiaomi Mi A2 / 6X Questions & Answers] Mixz1890:
To me it seems like the rom itself of your phone is corrupted during update. I'd suggest a clean install of the rom and try updating again. That could fix the issue because youre the first one here to report that.

[Xiaomi Mi A2 / 6X Questions & Answers] Midomad:

Clean install won't help,they should fix it via update like they did with the first "lock at max cpu frequency" bug.
[Xiaomi Mi A2 / 6X Questions & Answers] pack21:
Sorry for intervening, but i see here some misinformation, when some say 1401mhz stuck freq it's a new bug, it's not new, it's always been there since we started talking at max frequency bug, when we early change the governor to solve the maximum frequencies, the 14i0mhz stuck would always appear after a while.

So for me, the bug was not resolved, they just do what we always do changing the governor's settings, but messing 1401mhz freq .

If you spend some time reading this topic from the beginning you will see several references at 1401mhz bug.
[Xiaomi Mi A2 / 6X Questions & Answers] carloandreaguilar:
I've had it only once in the past 10 days. GOODIX as well. Maybe it's because of a setting or an app some people have and some don't. That would explain why only some people get it. I also did factory reset after 2nd October update, got the bug on the 6th day, rebooted, haven't had it since.
