Banking App Won't Submit: Err500

[Sammy345]

My banking app has a mandatory update OS flag which wouldn't let app execute, even older versions of it.

Using the newest APK version for my phone (7.5) changed only the version name and code to the newest app (8.6.1). Flag is gone -YAY. Now I can execute and use it but get error 500 when I try to submit the transaction to the bank. What am I doing wrong? The software executes perfectly. No warnings there. Used APK Icon Editor. Thanks.

I would say the error is because of a check the bank is doing for the version of the app, or to see if the app has been tampered with. Since you've tampered with a financial app, I would expect it to not work.

Are you doing this because your phone won't update to an OS version that is supported by the latest version of the app?

I am doing it because I shouldn't have to update my OS to use one app. No idea if my phone which has low internal memory already will fare well with it. The newest version of the app is for 4.4 and above. There is NO reason all versions of the app going back before 4.4 existed should require update. It's a bug. I should be able to install and use the app compatible with my OS not have to upgrade. And I still have to login for security so that shouldn't be a problem.

Actually, no. Newer versions of the OS have newer APIs or Application Programming Interface. With those different APIs come different capabilities. If a core part of the app requires the new functionality of a newer OS, you HAVE to have the new OS. If said core functionality is required on the back-end that receives the requests, you then break that capability and handicap the app.

It's no fun, I understand that, but as a phone and the OS running on it age, you eventually age out of being able to run some apps. A banking app is one that I wouldn't want to mess around with, from a security standpoint.
