Banking app refuses to launch due to untrusted store

rofeki8011

Since the last update of my banking app (Consorsbank), it no longer starts. The error “The application was not installed from a trusted store (A053)” now appears in the app.

I downloaded the app from the Aurora Store, so I assume that this is the reason for the error message. However, I would like to avoid installing the Google Play Store on my phone if possible.

Is there any way to manipulate an app downloaded from the Aurora Store so that it thinks it was downloaded from the Play Store? Maybe my assumption is wrong and the problem is something else entirely? The error also occurs when Play Services is installed.

Yes. Steps:

Create a secondary profile. Disallow background usage of this profile.
Push the banking app to the secondary profile
log in to the secondary profile, install play services and store
wait for an update of the banking app to appear
search the banking app in the play store of the secondary profile. Instead of the install button you will see a update button. Tap it.
the update will update the app in the owner profile. It will say installed from Google Play Store.

I use this method to update apps, not only banking ones.

Tandara There is no way to bypass it, banking apps check their installation source.

This is BS. Most banking apps do not check their source and they even run without google. The fact that a single app does should not be generalised.

Hi there!
For the banking apps, it's recommended to use private space or secondary profile if you want to avoid installing GPlay in the owner profile. There is no way to bypass it, banking apps check their installation source.

sir unfortunately looks like they're not working on it but it is intended

schweizer Thanks, but that's not very helpful I'm already actively using my work profile and don't want to install Play Store there either. But I agree that Consorsbank is so far the first and only banking app I encounter that checks its install source.

Alternative is probably only a tan generator

HawkEy3 schweizer 's instructions here will allow use of the banking app in work profile without play services being there as mentioned in their reply to you.

Apps on a device share the app source across profiles while being isolated from each other with various instances, which is why updating an app in one user updates it across all users. Doing the steps they mention will update it in the work profile while also changing the install source to Play Store for it to function if that is all they're checking.

It appears that the problem has been identified and Consorsbank is working on it => LINK or LINK

There is now a main thread on their Subreddit discussing this issue https://www.reddit.com/r/Consorsbank/comments/1p909w1/consorsbank_schr%C3%A4nkt_app_nutzung_ein/

I do not know what you understood from my text but I gave you an instruction on how to install the app in your work profile without installing any google there.

HawkEy3

Ah sorry, then I misunderstood. I thought by "second profile" you mean the "work profile"
But then you need a google account and Play Store in your main (private) profile?

No. That is the whole point. I was not entirely clear. I should have written "create a new additional secondary profile". That profile will later have the sole purpose of updating your apps. It does not matter whether your work profile is the owner or not. Just follow the steps one by one and you will see it works. Trust us a little bit.

I see thanks, to be honest I didn't know that was possible, found a guide here. Still sceptical of installing google services on any profile.

I can understand. If your bank requires google and you want to continue to use it you must take a decision.

On the technical side you can register your google account on a free wifi such as coffee shop and use a fake name. Once it is set up it runs on Tor. I think this is the maximum privacy achievable with your boundary conditions.
