I tried this with two Xperia 10 II phones, one running 4.2.0.21 (updated OTA from 4.2.0.24) and another running 4.3.0.x (the upcoming OS release). On both phones, call audio was automatically connected to the JBL TUNE750BTNC headset.
This worked okay both for incoming and outgoing calls.
Music playback worked, too. In addition, I watched a video stream from YLE Areena for 1.5 hours with the JBL headset without any hassle.
And againā¦ Sometimes wifi with android apps works, sometimes it doesntā¦ I dont get it. XA2.
Thanks for the reply! TL;DR Now it works for me, too! But why?
Longer story:
I first tested my paired device once again; calls didnāt work. I then opened /var/lib/bluetooth/[MAC]/info and noticed that HSP was the last item on the list. I turned off Bluetooth, moved it first on the list, connected again, and lo and behold - calls worked!
Then I did several cache cleanings, order changes and pairings, and couldnāt make it not work again. The placement of the HSP profile in the list varies, and it doesnāt seem to affect the result anymore; it just works. Oh well! It works, and thatās the important bit 
iāve belatedly noticed this new blog post about 4.2:
Does this mean it is actually out?
Jollaās marketing serves only to confuse meā¦
Yes, itās out, check the opening post for details 
But you are correct. I didnāt notice that the 4.2.0.21 EA had turned into public release until two days after.
If we consider the blog post to be āthe official announcement to the massesā (as the forum thread is created at first EA), then subscribing to the RSS feed helps. Which I may or may not just have found out about myself 
These two bugs were fixed with 4.2.0.21, could you add them to the list?
Iām trying to install the update on a Xperia 10.
The update does not start because I donāt have enough free space in my system partition. Required is 500MB and I only have 309,8MB. When I look at the details, I see Sailfish-apps use up 248,3MB. So basically I have to remove all Sailfish apps to be able to update. I clearly donĀ“t want to do that.
Is there another way I can update? Seems like the system partition is just way to small.
I have the same or similar issue. Some/many avatar pictures are missing (but not all) from the āPeopleā application after the upgrade to 4.2.0.21 on my Xperia XA2. I suspect it is the older avatars where the original picture each avatar was created from is no longer present in the gallery.
Currently trying a restore from backup to see if that helpsā¦
Edit to add: Restore from backup did not fix the problem. Iām going to have to use some developer access. It looks like a recurrence of a known upgrade bug that occurred with Kvarken (4.1.0.24).
At least I have an old backup that I should be able to restore the avatars from. Sigh. Another entry on my to-do list.
I must admit, Iām not a fan of the new display of open tabs in the browser. If there is a way of reverting to the old style, Iād like to know.
The new one shows more of the page for each of the web-page tabs. Which is nice, but means with my large number of open tabs, it makes navigation difficult, and I find it more difficult to retain ācontextā of where I am in the list of tabs. Frankly a simple scrollable list of (full) URLs would be more useful to me with an option to show either no thumbnails, small thumbnails or BIG THUMBNAILS (which is the present look).
Where is the opening post?
Does that mean that the SFOS 4.2.0.21 turns into current official release by definition and not by any change or new version since 4.2.0.21EA?
I have 4.2.0.21 since it was EA released, and now phone says āno update availableā.
Are there now any changes between 4.2.0.21 EA (abt 2 weeks ago) and now? Should I do an update by command line, because the updater (settings/updates) doesnāt see anything new. I ask because I donāt want to miss anything.

Itās the first post in this thread.

As far as I know, yes.

4.2.0.21 was released to EA on 2021-09-13 and for all three days later. My phones donāt find any updates via Settings nor terminal, so they are up to date.
should i be worried in my XA2 Plus has the upgrade progress bar stuck at nearly 100% complete for twenty minutes now?
Email.
Iām not impressed*.
It appears the upgrade process dropped the email cache, and reverted server passwords to ādefaultā. I have a lot of emails, and having to scroll to the bottom of the screen and select āGet more emailsā to get them back on-device is a big chore**. And it looks like the read/unread flags have gone, so all the emails downloaded (again) show as unread.
*Donāt get me wrong. I a BIG fan of SailfishOS and Jolla, so I hope my feedback helps to improve things for everyone in future.
**Would be nice to have a ādownload all emails optionā or ādownload emailsā where ānā can be varied by the user. And while Iām at it, having collapsible folders in the folder view would be useful.
Edit to add: turns out I was wrong about the unread flag. Ii just turned out the most recent emails in my inbox were all unread. Spending too long on upgrading the phone, I guess.
Downloading the whole inbox sounds like a nice feature to have. Could you create a bug report for it?
Before you re-enter all the passwords, give the device another reboot first.
Donāt worry, 20 minutes is in the normal range. Before an hour of no proceeding, i suggest to simply wait and do nothing.
Sorry, too late. I did do a full power-off restart before entering the correct passwords.
However, it could be that the restore from backup to try and solve the missing avatars in the People app issue mucked things up.
With regard to creating a bug for the requested inbox feature, I will: but not immediately as I have to do all the stuff I put on hold to upgrade the phone (smile). I would recommend having a ādownload further emailsā feature, rather than just the whole inbox, as some inboxes are rather large. I just checked on my desktop PC, and the IMAP folder is 2.2 GB in size. It is not unusual for me to need to go back more than 5 years to find stuff relevant to what I am doing today.
Restoring a backup which contains accounts clears all saved passwords, this is by design.
When I quick-scrolled to the end of my inbox, in the bottom pull-up menu thereās an option to get more messages. Is that not what you meant?
My install got stuck for about 2 hours (the progress bar looked to be at 100%). I got a little impatient and just restarted the device. it booted successfully and it looks like I have 4.2 now installed.
Is there anything I should check or is there any way to find out if my system is actually completely updated?
Ps. i restarted because i thought my phone was bricked and i need to reflash
this is where I am, it is now three hours later and my phones progress bar for the flashing is still stuck at/near 100%.
seems like you faced a similar situation and emerged unscathed, so I might as well restart mine too with fingers crossedā¦ not like I can leave it there forever!
[update] is there a key combo to force a reset on an XA2 Plus, because it doesnāt seem to respond to the power button alone right nowā¦?
Well i have a XA2 Ultra but for me power + volume up + volume down worked.
i hope everything works for you!
