Description of the app's functionality

app works with and without Google GSF and GMS with native code debugging disabled, details below.

Without GSF and GMS

• On start, App displays warning that IKO will not work without Google Play Services which are not supported by this device, but launches normally.
• App works normally (including connecting app to the account) except notifications. Enabling or disabling notifications have no impact, but if enabled they can be viewed after launching the app and tapping the appropriate button.
• Nearby departments, ATMs etc. untested (it requires location permission and may want to use GSF/GMS location services).

with GSF and GMS

The app is working. No issues have been noticed. Nearby departments, ATMs etc. untested (it requires location permission and may want to use GSF/GMS location services).

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

Don't install the app to secondary and/or work profiles on devices with android 12+ unless you are not planning to use contactless payments via NFC. NFC payments are not supported for secondary/work profiles on Android 12+ for some reason - NFC can be enabled or disabled only.

ADB logcat of the app if necessary

Thanks for the feed back. We really appreciate it.

Don't install v3.140.28 (version code: 45359), at least without Google Play. From this version the targetSdk was razed to 33 and some libs were probably bumped too. Impossible to launch at all, it throws message like something went wrong, we're working already on this. It's not GOS-related issue, for all devices without GMS or MicroG.

Not tested with (Sandboxed) Google Play yet.

Last working:

• v3.139.26 (version code: 44595)
• v3.139.27.hms (version code: 44779) - from Huawei App Gallery (latest as of time of last edit - October 18th 2022)

@PatrykMis I've created a post addressing this here https://akc3n.page/posts/banking-app-issues/ with some possible solutions. Please let us know if your issue is resolved afterwards. Thanks.

Of course I tried it already. The issue still exists with native code debugging enabled and Exploit Protection Compatibility Mode - forgot to mention, sorry. I have tried granting all permissions, too.

[PatrykMis]

After extensive testing it on different devices, OSses and configurations, finally I can confirm that app requires GMS (or eventually MicroG) to work, even to run properly. The only workarround is to use HMS-based version from Huawei App Gallery and skipping dialogue to install HMS services each time (fortunately, HMS version is signed by the same key). Further more, it throws error on contactless payments but payment is successful. Thus, I recommend setting PIN code for contactless payments to be entered on a terminal, not in the app.
