Recently, when I go to open my Kasikorn Bank app, it says I have an app/s from an unknown source, which I do, they are not from the Play Store, and I basically have to delete it / them to be able to get into my Kasikorn Bank App.

How is it that one app can see other apps that are on your phone?

To the Mods, I'll post the same thread in the banking section. Take your pick which one you want to let run. I'll lean towards the IT Section because it seems like a breach of privacy to me.

Android identifies non-store apps by checking the package installer signature registered during setup. Key identifiers include a missing or non-standard installer package name, lack of an official marketplace signature, and system flags indicating manual APK sideloading.

Android installer only sees these installation keys or flags, not what's "inside" the app or any user information. Although Android and Windows app security methods aren't the same, the warning you see is similar to one that a Windows device displays if you are trying to install a program that's incompatible with the device hardware or software that's already installed.

If an app isn't sourced and installed from the Play Store, it could interact or otherwise compromise the integrity of the banking app, or any other app that was installed via the Play Store.

I had the same issue with a side loaded GPS app that I needed for work with a Chinese contractor. Although I was no longer using the app, I had to remove it as several Play Store apps either wouldn't install or launch due to its presence on my phone.

As a workaround, you may need to have two phones: a "clean" one for banking and other apps that require personal information, and another one for the apps that have been side loaded or not available on Play Store.

Thanks.

The Kasikorn app had been working fine, and along side, the app from an "unknown source" until not long before I started this thread. So, I'm guessing it was Kasikorn that caused this, not the Google Play Store.

Coincidentally, I have another app that now will not work because my phone is in "developer mode." The reason I have my phone in developer mode is because I occasionally transfer photos to my PC and I have to allow this in the developer mode settings. So, I have to disable developer mode, use the app, then go into settings and tap 7 times on the build number to enable developer mode again.

I have read about similar cases where the phone has been "rooted."

I'm all for cyber security and privacy, but it's starting to feel like I don't own my phone anymore.

I am now using an old phone I had for the Kasikorn app. I removed the offending app and it works fine.

You are probably correct in saying it's due to a change in the Kasikorn app. Apps are updated frequently and if you have auto-update enabled, you may not be aware an update has been done. For most secure apps, if there's a prompt to read/approve the terms and conditions when you open it, the app has just been updated.

Kasikorn possibly included a security update, hence it suddenly finding and flagging incompatibility with your device.

Blame Google. They are the ones who are locking down the 'open-source' Android system. If you were not aware here is the latest kerfuffle -

I agree. It appears to me that Thai banks have introduced much stricter controls within their apps compared to many western financial companies.

Even the MyAIS app won't work on my banking app phone due to a specific app - yet the SCB app works.........

How do you track down the specific app causing the problem?

Usually it will be an app that was NOT installed from the Store.

If all your apps did come from the Store and NOT side loaded, maybe check that all the installed apps are up to date?

Its due to a an app called Rethink DNS which can control which apps access the internet via various controls. I can put it on pause and the banking app works but for some reason not MyAis. So I just deleted MyAis.........wasn't doing anything for me anyway 😀
