Actually, there is a problem with App Support – it doesn’t start most of the time.
It starts fine if I do it manually from Settings.
It never (roughly) starts automatically on boot in spite of being set to do so.
It starts around 50% of the time when trying to start an Android app. Starting the Android app then immediately going into Settings → App Support may help.
This is new to 4.5 ie wasn’t in 4.4.x.x.
Tried by now: I passed from 4G to 3G and still have connectivity and mobile data on SIM2, the same for 2G which I am using to send this reply. I have the sensation that is about network operator OR because my SIM1 is set to 2G (I go to test). Nope, SIM1 4G and SIM2 in 2G connected with mobile data and here I am writing.
Customisations: my ofono is allowed to load the qmi plug-in which by default is disabled + the network on the SIM2 is set manually
Not a fix, but something that will make your life a little easier is a patch by @carmenfdezb which will let you add an Android Support toggle button to the Top Menu:
https://coderus.openrepos.net/pm2/project/android-support-button
(requires Patchmanager)
Already have it. Does uninstalling and reinstalling App Support wipe Android apps/data?
It does not support the last version 4.5.0.19 in which there is a similar icon for the topmenu but it brings to the Andorid Support page. This button is supposed to enable/disable the Android Support, instead. Is it right? Will the author update it for the last version, also?
Hi @robang74! The patch works in the last version of sfos, I’m using it without any problem.
And yes, this patch enable/disable Android support with a toggle
Sorry for being a newbie but how you can force the installation my Patch Manager warning me and prevents me to apply that patch.
I think that you have to enable developer mode from settings in Patchmanager, and select ‘No’ in ‘Check version’ option.
Thanks. In fact, at this time I have the strict check version enabled.
I just hope Jolla will release a new hotfix or let’s say, minor update to 4.5, to address hw acceleration on videos on browser not working, randomingly not login on passcode on my xperia 10, wifi status new page bugged, and some bugs exposed as 4.5.0.19.
Will be warmly welcomed 
edit: this, of course, before the next 4.6 update or whatever they are planning to do… who knows, a Sailfish 5 release wow
This link was working at the time I have posted here - as far as I remember - but now it does not work anymore and since v4.5.0.21 every images to download require some extra fields in the url: {Policy, Signature, Key-Pair-Id} which is supposed being unique for each customer / registered user.
You can also try this one:
and you will enjoy the 403 forbidden error. I think that this is an sensitive step towards a more restrictive distribution policy. With positive and negative implications, depending the point of view:
negative - because the community is even more thigh to Jolla Oy and its destiny
positive - because Jolla Oy affirmed in a practical way their right to limit the re-distribution of their proprietary software and the vendor’s one.
I cannot exclude that this decision has been taken under the pressure of the vendors, but I do not think it is about Sony because all the stuff is anonymously downloadable from their website. Possibly Qualcomm which is the producer of the SoC, instead.
UPDATE
For the next release, I suggest to apply this patch:

Possibly I am wrong but I remember to have used a direct link without any {Policy, Signature, Key-Pair-Id} to download that image. For sure in posting that link, I did not removed anything from.
Did ever check the download url from https://shop.jolla.com/ ?
If you did not, much probably I am right.
Instead, If you did that check in the past, did you saved the link?
Go to check that link and compare with the one you get from Jolla shop. 
Suggestion: if you download it from your browser, you have such a link in downloads browser page.
UPDATE
The Policy and Key_Pair_Id are constant among releases while Signature changes.
Update went almost perfect; Xperia XA2 seems little smoother, faster.
One issue: my openvpn entries were gone; had to reinstall them one by one.
Very nice job…thanks
Hello in this old topic.

Thank you.
this may be what you need, or one of the others in that folder. if not, good luck!
i have tried it already, but torrent seeding seems to be dead.
Perhaps one of these is useful to you? This temporary link was shared by sailors earlier on irc.
https://releases.sailfishos.org/images/tmp/
