hi, i’am facing the same issue for my standalone app.
It seems to be device independent. I can reproduce this behavior as described on genymotion and my HTC 10 (Android 7.1).
i don’t know if it helps but my app is called LAPPENBOARD and it’s available on Expo, Google Play Store and Apple App Store.
