The Samsung Galaxy Store is preloaded on all Galaxy smartphones and tablets worldwide.

UDP can repack your UDP build into an APK that meets Samsung’s requirements:

• implementing the latest public Samsung IAP SDK.
• having a .gs package name suffix.

Step 1 : On the UDP console, once your game revision is released, go to the Publish page and select Samsung Galaxy Store.

Step 2 : Select “Repack game” and hit the Publish button.

By selecting “Repack game” and hitting the “Publish” button, you acknowledge and agree (1) that the use of this repacking solution is at your own discretion and risk; (2) that you are solely responsible for any damage or loss results from such use; and (3) that Unity is not responsible and liable for such use.

Step 3 : In the Status page, download the repacked APK.

Step 4 : Connect to the Galaxy Store Seller Portal and go to your game.

Step 5 : Upload the repacked APK. Edit your game description and IAP information as needed.

Step 6 : Submit your game, and wait for the outcome of the Store Review from Samsung.

Step 7 : Release your game once approved.

If your game uses server-side IAP validation, you must ensure your game server application implements the Samsung IAP Server APIs. Your game build should request your game server to fetch the data from the Samsung IAP server using the Server APIs.

A: Yes. Your repacked build will have the same package name and the same signature as the builds you had previously submitted to Samsung Galaxy Store via UDP.

But starting from the game revisions repacked with the public Samsung IAP SDK (and submitted manually from the Galaxy Store Seller Portal) note that:

• UDP will not track their submission status.
• UDP will not track their IAP transactions and revenue. But the usage data (users, sessions, etc) is still tracked in the UDP Reporting dashboard.

A: Creating a Release on UDP is a prerequisite to start processing the game for the stores. Since UDP is meant to submit your game to multiple stores, we decided to maintain the requirement of providing the minimum metadata and IAP information for a store submission.We however strongly advise that you input real metadata and IAP information so you can easily submit your game to the other stores on UDP. Remember that you can import your game metadata from Google Play in a click, and import your IAP catalog in bulk with CSV files.

A: Yes. Follow the instructions in this guide to create the repacked build, making sure that you use the same package name and the same signature as for the build you already have on the Galaxy Store. The submission process is unchanged (directly / manually on the Galaxy Store Seller Portal).
