Sony Xperia III - Android 12

Could flashing the phone from Android 12 solve some bugs?
The echo cancellation and this bug are annoying.

Is this likely to be the case for the 10 II at some point too?

Unfortunately flashing Android 12 to your Xperia 10 III will not fix echo cancellation issue. Discussed also over here. Further, I do not believe that disappearing sound and freezing video would get fixed either.

From my past experience it has been actually other way round. When developers have (back)ported something for a device adaptation let’s say for wlan driver, then when upgrading beyond the recommended Android version the wlan driver started acting up as the adaptation fix no longer worker.

The audio bug is also present when Android 12 was installed prior to SFOS. I tested Android 12 and 3 different Android 11 releases and the bug always occurs.

This good news.
The first thing my 10 III did at power on/config, was to immediately update to android 12 as soon as the wifi was running.

This nice gentleperson has kept an archive of past Sony firmware packs, including the 62.0.A.9.11, enabling a simple and direct path using newflasher, rather than jumping through multiple hoops.

Could you also tell us which is the recommended Android 11 version?
62.0.A.3.109 that can be installed by Emma, and version that shipped with my phone,
or 62.0.A.9.11 that can be installed by OTA?
What is the recommended one? Official guide only mentions the first one, and not doing any further OTAs, meanwhile people here recommended to OTA. Which one was tested the most?

Thank you @olf for noticing this.

Could you also confirm which version of Android 11 is the official and recommended one, as I asked 3 posts above?

Slightly OT: what are the conditions for getting OTA upgrades in android?
I had 62.0.A.3.17 and 62.0.A.3.109 flashed with EMMA, bootloader locked (fastboot oem lock) but no update notification received . I will probably flash v12 via newflasher to see if it makes a difference for this topic Unable to use mobile data on Sony Xperia 10 III 4.4.0.64 - #67 by rtr2001

I know other Android devices disable OTA updates when the bootloader is ulocked, not sure about Sony though.

I read somewhere that OTA is disabled for unlocked phones . Hence I have locked right after flashing Android and only booted with locked bootloader. No update notification found. Interestingly, EMMA tool only sees two versions of Android 11…

I had no problem from Android 12. Used the phone week as Android to make sure all is O Ok

@rtr2001 @Dickus51 It should work, but is not recommended

@rainemak: Still as of 2022-09-12.

I installed with Android 12, installation went fine… and i am using SFOS from almost a month. all is fine…

Hope this helps

In the end I connected it again to USB and rebooted using fastboot reboot . That worked well.

God bless you.

Thank you @rainemak for addressing this, but unfortunately now the footnote 4 is broken and footnote 5 is missing.

My suggestion how to fix this: Alter
[4] Both Android 11 and Android 12 are compatible with Sailfish. However, we recommend using Android 11, so select Android baseband 59.1.A.x.y if available.
to
[4] Both Android 10 and Android 11 are compatible with Sailfish. However, we recommend using Android 11, so select Android baseband 59.1.A.x.y if available.
[5] Both Android 11 and Android 12 are compatible with Sailfish. However, we still recommend using Android 11, so select Android baseband 62.0.A.x.y if available.
and append a [5] to the second column of the Xperia 10 III entry.

HTH
