Description of the app's functionality

Everything works as expected after a clean install without any modifications. I don't use the app for much besides checking my balance.

The app doesn't launch if ADB is enabled. It will display an error message telling the user to disable ADB before allowing them to use the app.

The app works if OEM unlock is enabled. Guess this means they don't have too many security checks built in.

Are there any extra notes you think users should know about?

Just thought I'd add this for the maintainer of this repository. I'm sorry, but this app doesn't have an English name, nor does it have an English version, so I listed its Chinese name in the "App Name" field as it appears in Google Play. The app drawer name is slightly shorter, but that doesn't matter to someone who can read Chinese.

Suggestion for a better bilingual listing for your site: "E.Sun Bank / 玉山行動銀行", or "E.Sun Bank" for an English only listing.

ADB logcat of the app if necessary

No response

Thank you @akfarrington

That's quite alright, appreciate the time you put into adding this helpful extra note.

Good to know. :-)

Hi @akc3n. Wasn't sure if I should open a new issue or not, so I'll try this first.

Unfortunately, the E.Sun Bank app is no longer working on GrapheneOS. Part of the error message roughly translates to "the system is not safe." Not a very helpful message. Bootloader unlocking and developer tools are disabled, so I suppose that means they've started use a ctsProfileMatch check.

Thanks for your work on this project!

Hi @akc3n,

I forgot about that setting sometimes affecting banking apps.

I've toggled native code debugging and the app doesn't work with it enabled nor with it disabled.

Just tested with the December 20 release. All 3 GMS apps installed and with network permissions granted. Bank app is completely up to date, version 4.5.9.

Thanks!
