Hello all,

sometimes we need to get some services through a mobile app, but there is no such native app for the Sailfish OS. For this reason Jolla offers to install Android application on virtual Dalvik vm. And this is very good! But recently I faced with a strange issue: I tried to install the official application of Barclays bank and it said that it won't be installed on a rooted device. I didn't change my Jolla at all, so I have no idea why it shows me that message.

rooted devices are not supported by Barclays bank, Jolla

Does anyone know any workaround? is it possible to somehow solve this issue?

Thanks.

I would say, from the point of view of such a security critical app like banking app, the Jolla Alien Dalvik is rooted in fact: You have full access to all resources. If the banking app relies on Google that it is not tampered with, it cannot run on Sailfish ... Get Barclays to provide a properly designed app that is secure on its own.

I can understand your need for a work around, but this is more of an app problem than a Sailfish problem. Tell your bank to fix the app. If they don't care, well, there's a lot of banks around.

@evk Good point of view ;)

Thank you guys for your answers. It seems, that there is no easy solution for that issue at the moment :(

Don't use banking apps on your phone. Most of them are horribly insecure.

I use the Barclays app successfully. It is detecting root on Jolla because it can find a binary called "su" on the path, which is the native Jolla one that's there by default, but there'll be no such thing on a plain Android device. You can get the app to run by renaming /bin/su and /usr/bin/su to "suu" or something, TEMPORARILY.

BIG SCARY WARNING: DO NOT DO THIS ANY MORE THAN TEMPORARILY!! THIS IS A MASSIVELY BAD IDEA!!

(However! In my usage, all the native Jolla apps and the Store seem happy with no su binary available, and system updates when I've forgotten to rename the binaries back also seem to work, but some apps in OpenRepos rely on an su being present in their install/uninstall routines)

BUT SERIOUSLY, DON'T DO THIS!!

(but it does work)

YOU HAVE BEEN WARNED!!

Perfect!, this worked very well for me with a Foxtel Go app (pay tv in Australia), thanks for the tip!

Works for SkyGo too. Actually just renaming su binaries in /opt/alien/bin and /opt/alien/usr/bin did the trick

Gosh. SoneraViihde that otherwise would complain of device being rooted plays the vids just nicely now, but StartAsRootFileBrowser from OpenRepos that I used for renaming the files refuses to start up after the renaming, both with /bin and /opt/alien/bin methods. :D

I'm not sure, but I think apps under android test if the device is rooted i.e. by using the WRITE_EXTERNAL_STORAGE permission. You could download this permission remover app (http://www.plop.at/de/android/permission-remover.html), which I also use and remove the WRITE_EXTERNAL_STORAGE capability.

At least - last night when I played around with an .apk and removed WRITE_EXTERNAL_STORAGE, later the notification just before installing (in german) didn't mention any more developer-capabilites and other stuff, that I think is used to test for a rooted device.

Please try and let me know.

Doesn't work for me. I removed external storage rights with Advanced Permission Manager from Sonera Viihde app, but it complains about the device being rooted all the same.

For me latest NatWest app did not start at all, however older NatWest app version is working fine (apart to send a money to someone in my contact list). Maybe this would work for you too. just search for older Barclays apk.

I don't think it's a good idea to provide workarounds including editing files/folders, tweaking with system, using outdated app versions or using 3rd party unofficial solutions, when the question is about such apps like a banking app. Instead, the comment by @evk below the question is a better way to handle this, if using a banking app is a must.

Maybe I prefer changing my phone to changing my bank for my reasons. Sorry :-)

This answer is simple: to enable the fingerprint on natwest app for android and your phone is not rooted go to settings and search for display scaling. from there select standard view and restart phone. this will fix the log in with fingerprint issue.

Hello, has anyone tried to use TKApp (Health-insurance in Germany)? Does it work after renaming some files? May be it works, when should I use the old file-name? After using the app or after successful installing? Thanks for your help.
