XA2 with Sailfish OS 3.2.1 considered a ”Jailbroken” phone by Android app. [duplicate]
asked 2020-01-27 19:41:39 +0200
Today I installed a new mobilebank app released at beta level from the Danish bank Jyskebank. The Android app installs fine but the app stops at startup with this warning (translated from Danish) displayed:
"Access not possible
Due to security reasons you cannot use this because your mobile phone is jailbroken."
It seems the app checks and find the bootloader unlocked and therefore blocks the app from starting with the above message. I’m afraid this could be the beginning of a new rather big problem for ”alternative” Android versions.
1) Has anyone else experienced this problem?
2) Does anyone know if its possible to develop a solution that can re-lock the bootloader after installing SFOS?
3) Is it possible that Jolla somehow could reach an agreement with Sony that would solve the problem (allow relocking)?
4) If above is not possible, is it feasible that a software solution could be made showing the bootloader is locked, even it's not?
1) No 2) Not possible 3) Unlikely 4) Unlikely
Thank your bank and welcome to the victims.

I'm, personally, just visit bank's website.
Nerevareeeeeeee ( 2020-01-27 20:48:53 +0200 )editRelocking the bootloader is not possible, as that would prevent Sailfish OS from booting as AFAIK it is not signed by Sony like the official firmware images created by Sony are.
And even if the image was signed, the app is still effectively running in an emulator and might use some stupid tricks to detect that.
In any case, I also recommend using the Bank website instead of adding to the legitimization of banking apps telling you how you should use your mobile phone.
MartinK ( 2020-01-27 21:18:07 +0200 )editThe mentioned mobile banking app version, is in beta. The old version is still working, and accessing my bank accounts from a web browser is not a big problem in this case, though many websites work very poorly on a smartphone.
But to me this is a symptom of where Android apps may be going and for example the most used online payment solution in Denmark ”MobilePay” is only available as a mobile phone app.
The main Android apps Sailfish users are in need of are security focused apps like banking apps, official apps, transport apps, etc. many only available as apps, not via browsers.
Jolla has invested a lot of effort in upgrading the old Alien Dalvik solution to version 8.1 and this work may shortly prove to be wasted for the community if we can only use Sailfish on a Sony unlocked phone – I hope Jolla will consider this and seek to make Sailfish available for the community on some hardware not locked to Android OS. Or seek some alternative solution that could enable Android security focused apps that checks the bootloader.
DK-Sailor ( 2020-01-27 22:00:49 +0200 )editYes, I've seen this a few times, IIUC the last time with the My EE app. So far I have been able to either: (1) use the web site, or (2) say "OK, I'll switch to one of your rivals then" (like I did with Monzo, for example). I've been lucky so far that I haven't hit a real dealbreaker, although this will get harder as more and more aspects of daily life switch to mobile platforms. Here in the UK we aren't as far down this road as in Scandinavia, but even so.....
