Here is a recent email from the dev where they acknowledge that there is an incompatibility issue with some S7 Edge for months...

Just to explain one thing, the post from the Unreal forums you’ve shared on reddit was a very old post and is not linked to your actual crash.

This « old » crash was finally fixed before the launch of the game (https://answers.unrealengine.com/questions/405477/ue-release-4111-material-masked-s7-edge-gear-vrcra.html)

And just to explain more, the game was tested on many S6-S7 and S7 Edge before the launch, also with a complete team of QA testers (with many more phones) and we experienced no crash during this two months session test.

From what we’ve seen, the game crash only on very few S7 models and while it could be linked to an other app you have on your phone (for example a player have fixed this crash by removing an Xposed framework) this could be also due to a Samsung driver update. Oculus and us are working on it since this summer.

In any case you have to be refunded for sure, but have in mind that making a game with a very small team (4) and on this very new technology it’s not very easy^{^}

Thanks,
