In a recent update to the HSBC app they’ve added a screen to prevent you from using the app unless you use the default (google) keyboard.
They do a similar thing if you have an accessibility service running that can access the screens content. A fair enough security warning if you’ve happened to install a dodgy keyboard app, but highly frustrating when using an open source alternative that enhances the security and privacy over the default option (HeliBoard in my case).
I haven’t found a way to circumvent the page yet. It would be useful if Android allowed you to block the permission to query all packages, but alas.
I find banking apps pretty infuriating. Don’t support rooted/custom rom. Too easy to make mistake. Susceptible to ‘malware’ (ie intent jacking or if the app logs tokens in logcat lol). I use netbanking when needed. For txn logs, mostly SMS works fine.
I find keeping bank account logged in always isn’t necessary and just a invitation of hassles.
