[Sony Xperia 1 III] q173242:
Tried the RU A12 Version (for XQ-BC72) on my European XQ-BC52 - flashed without a problem.

But I lost cellular connection completely - told me no SIM installed.

Reverting back to A11 for now.

Edit: should have read the entire thread, cannot go back to A11 with locked bootloader.....
[Sony Xperia 1 III] dimenfer:
Someone uploaded a video on YouTube Saturday and there's no sign of Themes anywhere, sadly the uploaded removed the video, probably cause it didn't hide the IMEI, Xperia ID and things like that.

I went back because of some theme issues. But I fixed them. And. I'm. Fully root with writable system editsView attachment 5505425View attachment 5505423

Which carrier are you on?
[Sony Xperia 1 III] DennisDD78:
So, friends, is it possible to roll back to A11 with locked BL or not ??? It seems to me that there shouldn`t be any problems to roll back with Newflasher....

Or am i wrong ?
[Sony Xperia 1 III] DennisDD78:
My device from China XQ-BC72 is now with it`s native CH f/w A11, and i want to flash Russian A12 f/w. I`m worrying if something go wrong while flashing, can i flash back CH A11 f/w ?
[Sony Xperia 1 III] serenize:
No. You cannot go back to android 11 unless your boot loader is unlocked.
[Sony Xperia 1 III] q173242:
I flashed back to A11, but as stated I had to unlock bootloader, flashed A11 and relocked BL.

Let's see if OTA still works - I also did a restore in Xperia Companion after relock.
[Sony Xperia 1 III] DennisDD78:
Oh these new Xperias...:rolleyes:🙈
[Sony Xperia 1 III] DennisDD78:
And what happened when you tried to back to A11 before you unlock BL? You've got "device corrupt" when boot ? And why did you decide to back to A11?
[Sony Xperia 1 III] q173242:
Flashing A11 with locked BL resulted in "bricked" device, no booting just some message like "device is corrupted and will not boot".

Had to go back because I lost cellular connectivity completely - I have European version.
[Sony Xperia 1 III] DennisDD78:
That`s right, 52 and 72 various versions, they have different modem soft.

Interesting, when your device has bricked, so you haven`t be able to boot the system, right ? And for BL unlocking "Allow factory unclok" option must be switch on in the developer mode, did you turned it on before flashing A12 or what ?
[Sony Xperia 1 III] q173242:
I flashed the A12 again which worked. So I could unlock bootloader.
[Sony Xperia 1 III] DennisDD78:
I`ve got you.

And after you unlocked BL you flashed A11 as usual with Newflasher? No new actions ? And A11 just flashed OK with unlocked BL ?
[Sony Xperia 1 III] q173242:
Yes after unlock I flashed A11, then locked bootloader and then also restored via the Sony Xperia Companion - I have read somewhere that this could solve some DRM problems but not sure.

Now waiting for the OTA to check if this still works.
[Sony Xperia 1 III] DennisDD78:
OTA will work, for sure, but DRM keys lost forever, sorry.((

But i don`t know do these keys affect any functionality or not really.
[Sony Xperia 1 III] q173242:
Hmm I was also wondering, what these DRM keys actually affected.

Any ideas?
[Sony Xperia 1 III] bountyman334:
That means just you have to reflash from the beginning. And unlock your bootloader. You'll still have Google payView attachment 5505743

VoLTE and WiFi calling are only available on XQ-BC72? Because I don't have these options on my XQ-BC52. Or it will show up when I'll update mine to A12? For A12, I'll have to wait for a while.... Hélas...

WIFI calling is NOT controlled by Sony, or any other OEM. To get WIFI calling you need to contact your carrier and see if they will give it to you. The carrier controls VoLTE, and WIFI calling.

I installed Android 12 and it's so smooth that I disabled 120hz and only use 60hz to save battery! Not much big differences but UI got so nice in general.
[Sony Xperia 1 III] aoiharu:
It seems slower to me compared to a more snappy 11
[Sony Xperia 1 III] alirezaircn:
When on 11, even with 120hz, while switching to other apps had always a bit of lag, now it's gone. If you like snappy, then go to developer options and set animations to 0.

For me, now my xperia 1 III is as smooth as my iphone 13 pro max.

So thats means its a Sony software bug and not T-Mobile?

[Sony Xperia 1 III] UsernameNotRecognized:
Very dumb comment from me, have you enabled it?

I'm using T-Mobile NL and it works, but you need to enable it in your carrier settings.
[Sony Xperia 1 III] Evil_Sephiroth:
Becouse cost is unrelated. Like for car and any other stuff.

Iphone 4S (italian phone) never worked with Wind sim card (italian ISP) becouse Apple changed something from iphone 4 in the 3g module and that was not fully compatible with wind repeater.

And that issue was a lot big. A phone sold directly in Italy that don't work (totally) with one of the major ISP

And the 4s was a costly phone.

Also remember that if you buy a phone not intended and sold for your market you are open to those issues unfortunately.

Can you determine if this update/upgrade to Android 12 brought with it a change to the way 5G works? To check please go to settings > system > advanced > developer options (assuming you have it turned on) > scroll down to the networking section and tap "Prefer 5G NR Mode" > then tap on your provider (mine is T-Mobile) then select SA mode and see if you can connect to 5G. If yes then that's great. If you have to select NSA alone, or NSA + SA to get 5G to work then nothing has changed. Thanks for your help!

[Sony Xperia 1 III] hotcakes_shinku:
The Assistant Button is not customizable here either on my HK version. For those in the EU using EU region firmware, if you can't customize the button, you should write to the European Commission, telling them that Sony is enabling Google's monopoly. Hopefully it is enough for them to take some action and that action will trickle down to other region builds.

I find it as a good idea. Also not giving us all stock features that Android 12 brings like Material U.

[EDIT]Also, power menu has no GPay anymore. Pulldown menu is much worse - no dedicated setting fow WiFi/mobile data anymore. System-menu looks aweful - it's so plain yet so bad. I cannot rebind the Google Assistant button. Notification-profile switches(above the volume) changed (to the worse).

But one positive thing at least: There is a quick setting for extra-dark screen.[/EDIT]

On a positive note 5G SA seems to work, but I'll probably not be in a cell that supports it until ~three weeks from now so don't hold your breath.

This One hand mode on Android 12 is trash. If you activate it you only get upper half of screen. And if you enter in app then you are out of One hand mode. One hand mode on Android 11 was so nuch better. True One hand mode not this half made One hand mode.

Whar do you mean by "you cannot use 4k on Android 12" ?

Do you mean 4K reslution of the display?

By default the screen res is more like 2k, 1096x2560, try wm size. In A11 you could force this to 4k by using the same command, but that doesn't work anymore. Sad.

IIRC Sony has only whitelisted some apps, in these the resolution will go to 4k. Else 2k. So technically they're not 100% wrong, but far from right.

This will prevent assistant from appearing at all and will cause it to ALWAYS work.

Xperi+ typically only really worked while the device was unlocked and always rapidly showed the assistant on the bottom.

To solve the latter you can just uninstall google (or disable...), but not being able to use it while locked was a deal breaker.

Has anyone checked to see if Sony has added a workaround for Google's attack on microSD cards? It sucks that this phone has a microSD slot but it's effectively disabled in Android 11.

OsmAnd+ 4.0.9 using /storage/XXXX-XXXX/OsmAnd with the legacy API launches in a few seconds and renders fluidly even with the entire Earth downloaded.

New OsmAnd+ 4.1.9 using the mandatory /storage/XXXX-XXXX/Android/data/net.osmand.plus/files locks up for 30 to 60 minutes at a time. If I scroll the map around quickly, the phone locks up and reboots. There's no privilege in ADB that can be granted to allow it to use a non-SAF directory. Believe me, I've tried.

Google has hundreds of tickets like this that were inappropriately closed:

I've known about the adb workaround since xda posted last year.

Bring back the Wi-Fi and Mobile data Quick Settings tiles in Android 12 using these ADB commands

You can easily bring back the Wi-Fi and Mobile data Quick Settings tiles in Android 12 by running two ADB commands. Read on to learn more.

www.xda-developers.com

And I prefer to be at the mercy of Sony, instead of the mercy of Google. If Sony brings back separate toggles officially, it should stay there forever. However using an adb workaround, which Google can remove at any time through security updates, is not reassuring. I trust Sony of keeping features there which they implement more than Google. Take note I'm only comparing Sony to Google, don't bring in other companies/manufacturers into your argument.
[Sony Xperia 1 III] jaseman:
I have used ADB for many things and the only time something goes back to original is when you do a factory reset. At least that has been my experience. I doubt that Google cares about quick toggle manipulation. YMMV
[Sony Xperia 1 III] HIXPERIA:
Someone on Reddit mentioned Facebook app is removed after Android 12, probably meaning no longer pre-installed. Can anyone confirm this?
[Sony Xperia 1 III] Caroleus:
Nope, android 12 (XQ-BC52) - still had to get rid of it manually.

edit: same with tidal 3 month trial, couldnt uninstall it even after installing tidal lol
[Sony Xperia 1 III] hotcakes_shinku:
I do not think Google cares too. And I have plenty of ADB experience don't you worry.

However, the separate toggles are now legacy code. Google may not remove the command in ADB. They can however just outright remove the code for separate toggles from Android itself. If the code doesn't exists in Android anymore, ADB commands do nothing.

Legacy codes will sooner or later be considered unused codes. By removing unused codes, we keep the programming simple and lean, which reduces storage usage and increases performance. It removes potential security vulnerabilities as well as bugs. As much as I want to use those separate toggles, I support removing unmaintained codes for the above instead of dealing with those issues. If they are not going to dedicate resources to fix bugs or patch vulnerabilities related to the existence of that code, please remove it.

And we all know Googles reputation too well of not listening to what their customers or even their partner phone manufacturers want. If they want to they will just abandon it and in the future remove it for the above reasons.
