Maybe you have a problem with your launcher? Try different one.

To be honest, fingerprint unlock never been so quick and reliable as it is now in Pie. I am very satisfied.

Tested with system Quickstep launcher and Nova launcher.

---------- Post added at 16:09 ---------- Previous post was at 15:57 ----------

Exactly what version did you update your mobile phone?

My story is opposite:

On 23rd December update popped as official stable update for my phone and so it was installed on my non rooted pure stock 8.1.0 Oreo Mi A1.

So I have got Pie PKQ1.180917.001.V10.0.3.0.PDHMIFK and since then I have the same problem with LTE.

VoLTE is disabled and cannot be enabled by dialing *#*#86583#*#* as before on Oreo, so I cannot use VoLTE anymore because critical LTE Bands are missing.

After the update supported bands are just 1/3/5/40/41, so for O2 in the Czech Republic are missing bands 7/20/38!

But Mi A1 should support bands 1/3/4/5/7/8/20/38/40 OOB in Europe!

So I am waiting for the critical patch which Xiaomi should have released immediately, but they are lazy as hell, it is more than 10 days for me, but for example Nederland's users are waiting for patch a few weeks already!
[Xiaomi Mi A1 Guides, News, & Discussion] m1nd:
I have that exact version number and my provider only uses bands 7 and 20 for 4g and is known to shut off everyone who can't get on there and tries to use 3g or 2g. So im damn sure those bands work for me. Really strange that its not the case for you.
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
I am not alone and I agree that it is really strange.

I read post where in family they have the same Xiaomi Mi A1 model with the latest stock Oreo 8.1.0 version, they have the same mobile operator and after update one phone has LTE bands and another hasn't. So Xiaomi has even more difficult bug to solve than we can imagine.
[Xiaomi Mi A1 Guides, News, & Discussion] ZeRoX93:
I bought my Mi A1 in Slovakia and I still didn't get the Pie update.

Tired VPN and clearing data from Google framework etc.

Did they maybe stopped the roll out off the PIE update?
[Xiaomi Mi A1 Guides, News, & Discussion] m1nd:
In the netherlands they did not
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
You didn't read even a few last posts before you ask?

Update is stopped (at least for CZ/SK).

Or do you want to lost LTE bands too?

If you cleared data for Google Service Framework prepare yourself for factory reset.

That was really stupid step.

https://www.reddit.com/r/Android/comments/1r1n5z/_/cdiymrp/

---------- Post added at 17:11 ---------- Previous post was at 17:05 ----------

Xiaomi should stop update for whole Europe because of problem with missing bands.

If they didn't maybe the aren't still aware about it, unbelievable.

So I urge everyone with missing LTE bands, inform about it your operator so they can urge Xiaomi on higher level.
[Xiaomi Mi A1 Guides, News, & Discussion] _mysiak_:
Situation with LTE bands is very interesting. I have all of them still working fine (stock rooted pie, updated via OTA). Friend of mine with fully stock phone lost 4G after the official OTA update. Same phone, same build, same country, different result..go figure :)
[Xiaomi Mi A1 Guides, News, & Discussion] m1nd:
They pulled the netherland update around the 14th and put it back up a few days later and with a difference size in mb's. This is the working version with all bands so I don't think they should pull it. They need to make sure you all get that version
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
My update was 1069.1MB big.

You confirmed that you have the same version. So how can you say this:

When evidently the same version doesn't work for everyone?

See the _mysiak_'s experience:
[Xiaomi Mi A1 Guides, News, & Discussion] m1nd:
It is possible that its the same version number but not the same update. I meant that they should make sure you all get the working version that I got installed now:) Not a version that works for some people and not for others obviously. I am confused why you would think that I would want that
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
That is your own pure speculation which is not true.

Your PKQ1.180917.001.V10.0.3.0.PDHMIFK is the same as mine PKQ1.180917.001.V10.0.3.0.PDHMIFK. By the way how big was your update?

We have in this thread already many examples when the same update lead to different LTE bands set for different users.

I understand what you have mean, but see my previous point.

I've never think that you would want that :)
[Xiaomi Mi A1 Guides, News, & Discussion] m1nd:
I did not know! In that case they do need to stop pushing this update untill they have a build that works for all of us:)
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
It is a sad and cruel irony,

that users with root have no problem with update itself, or with solving post update problem when **** happens and some bands are missing

and users without root have problem with update itself and cannot resuscitate missing bands:

[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
I contacted O2 CZ, they told me that possible reason for my problem with missing LTE bands is that I activated VoLTE with unofficially method by dialing *#*#86583#*#* => *#*#VOLTE#*#*.

So I want to ask everyone with missing LTE bands whether you also enabled/used VoLTE prior update?
[Xiaomi Mi A1 Guides, News, & Discussion] macelaru:
Yep. :eek:
[Xiaomi Mi A1 Guides, News, & Discussion] denisval:
Nope, never used VoLTE in my life. Also: no root, no unlocked bootloader or whatever. Just received both updates OTA and I use my dual sim.
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
So that was only pure speculation from their side which is not true. I thought so.

About me: I was using VoLTE permanently. No root, no unlocked bootloader. Just received 1069.1MB big PKQ1.180917.001.V10.0.3.0.PDHMIFK OTA update. I have only one sim.
[Xiaomi Mi A1 Guides, News, & Discussion] _mysiak_:
I activated unsupported VoLTE on Oreo (it didn't work anyway) and LTE bands are still here.. :)
[Xiaomi Mi A1 Guides, News, & Discussion] macelaru:
So we have Volte activated with missing bands.

Also Volte activated and no missing bands.

But also no Volte activated and missing bands.

And of course no Volte activated but no missing bands.

Mind-boggling.
[Xiaomi Mi A1 Guides, News, & Discussion] _jis_:
Not mind-boggling, we have proof that activation of VoLTE prior update and missing LTE channels after update are not related in any way :)
[Xiaomi Mi A1 Guides, News, & Discussion] denisval:
Tbh. Xiaomi is being really quiet about this, no communication whatsoever. That's what's bugging me because we are completely in the dark as to when we can expect our phones to work as phones again. My network connection is very unstable, it seems like it's always trying to get a better signal but then falls back to edge or absolutely nothing.

If there remains no communication I'll have to buy a new phone because, let's be honest, it doesn't feel like they are putting this on top of their priority list and I don't demand a lot from my phone but a stable network connection is kind of a bare minimum for me.

edit: it's quite the shame because this might be one of the most enjoyable smartphones I've owned so far but they kind of ruined it with something as stupid as a poorly tested update.

No reset or factory reset, just updated 8.1.0 01.11.2018 OPM1.171019.026.V9.6.8.0.ODHMIFE on 24.12.2018 to 1069.1MB 05.12.2018 PKQ1.180917.001.V10.0.3.0.PDHMIFK and lost LTE channels 7/20 and today I updated to 71.5MB 05.01.2018 PKQ1.180917.001.V10.0.4.0.PDHMIXM and got the LTE channels back. I already tested channels 1/3/7/20 in real.

It is interesting that Mi A1 with Oreo supported bands 1/3/4/5/7/8/20/38/40, but now it support even one more band 1/2/3/4/5/7/8/20/38/40.

I checked it with QXDM: NV Browser/LTE BC Config/687195291871.

Some app probably mounted system as RW, so the only solution is to wait for stock fastboot rom. Happened to me as well, I suspect Substratum, it seems to write into system partition on each boot, despite the fact that it is supposed to use Magisk systemless module.

[Xiaomi Mi A1 Guides, News, & Discussion] jack_21:
The update was buggy, the phone should support LTE band 1, 3, 5, 7, 8, 20, 38, 40 and after Pie update it only supports 1, 3, 5, 40, 41.

You must wait a fix from Xiaomi, or you have to edit NV values with QXDM (but it's a long procedure and it can go wrong if you don't pay attention).

I suggest you to wait, however if you want here there is a guide.

BTW phone also support band 4 that is the band I lost, I used it here in Mexico
[Xiaomi Mi A1 Guides, News, & Discussion] TrueMS:
Dont worry, we dont think its the issue of VPN method but of the official Pie made by Xiaomi. It somehow restricted the LTE bands in this version.

[Xiaomi Mi A1 Guides, News, & Discussion] arc4d14n:
Yes it does, but not all users are affected, and It also depends on the region you are currently at.... But there is no doubt that some bands are being erased as far as I've seen, Band 4, 7 and 5 are affected, again, not in all cases, you are lucky, but we should be aware of the posibility that this might happen.....
[Xiaomi Mi A1 Guides, News, & Discussion] redbullman:
It doesn't ruin 4g xiaomi have just missed off some bands. There is only one version of the update. Wait for xiaomi fix.

As you can see, you are connected to Band 3, that was not removed by the bug.
