Hello Epic Staff,
Here’s an interesting issue that’s easily replicated.
- Launch “Epic Launcher”
- Press “Launch Unreal Engine 4.14.1” button
- Click “New Project” tab.
- Select “Blank” under the Blueprint tab.
- Set to Mobile/Tablet, Scalable 3D or 2D, No Starter Content. Enter any name for the project.
- File > Save Current As… > [Map Name]. Click Save.
- Build.
- Plug in any android phone or tablet.
- Select Launch > Target your Android phone or tablet device.
- Launch Fails. Filter Errors/Warnings in Error log.

Why would a blank project be targeting the PuzzleBP project?
So I fixed this issue by going into my Plugins and disabling the Substance plugin. However, there’s nothing that tells me that’s the cause of the issue, I just happened to disable it and that solved it. Might want to change error handling or disable Substance plugin on Mobile/Tablet projects.
I restart my project, try to launch again and it deploys to my Android device fine, but the warnings about PuzzleBP are still present.

Is this supposed to be present for a blank project? Thank you for your time!
