I have created an app by SDK 30 and submit it to Galaxy Store. The app was rejected: “Error. Installation failed. Try later (package.name - 103)”. But there is no error for Google Play Store.
So I just downgrade the SDK to 29, resubmit and the app was accepted.
Dear Samsung developer team, please pay attention about this bug.
Did the store show the device that it failed on?
I moved this to the Seller Portal forum

I expect the reason is just that test device needs to be updated.

May be I found the problem. APK file created by SDK 30 and high must have signature also by version 2 too.
