Dynamic shadows on Android moved in x-axis


I am having a strange rendering-problem with my game on Android.

I am currently developing a breakout-inspired game for Android-devices.
I am testing on an Xperia XA1 (Modell G3121) with Android 8.0.0
UE version is 4.20.

The game uses a single directional light with mobility set to movable, because I have moving objects, which require a dynamic lighting.

When previewing the game everything seems fine.
But when I build the APK (and OBB) and install it on the device, the shadows are drawn too far in -X direction (see screenshots).

Kind regards
