App Crashes when Opening Samsung Services Purchase Window

I would like to bring to your attention an issue that occurs on the Samsung Galaxy S8+ when using IAP services. Upon attempting to open the Samsung Services purchase window, the application unexpectedly rotates to the vertical orientation, even though our app is designed to be used exclusively in the horizontal orientation. Consequently, this leads to a crash in the application. It is important to note that this problem is not observed on other Samsung devices.

Steps to Reproduce:

  1. Launch application on the Samsung Galaxy S8+.
  2. Go to the store and start the purchase process.
  3. The application automatically rotates to the vertical orientation, contrary to the designated horizontal orientation.
  4. As a result, the application crashes.

Expected Behavior:
The application should remain in the horizontal orientation even when the Samsung Services purchase window is opened.

Tested Device Configuration:

Actions Taken:
We attempted to reproduce this issue on other Samsung Galaxy S8+ devices but were unable to replicate the error. Additionally, we have examined the Samsung developer documentation but did not find any relevant information that could assist us in resolving this problem.

We kindly request your assistance in identifying the root cause of this issue and providing recommendations for its resolution. If further information or collaboration with our team is required for clarification or additional testing, we are more than willing to provide all necessary resources.

Thank you for your attention to this matter, and we look forward to your support in resolving this issue.
