Physics problem (Android only)

Attached is a small Blueprint project with a “default level.” The level has 5 physics-enabled cubes put on top one another so that they should form a column when game starts. My project has one condition: physics has to be limited on the YZ plane (project settings: Engine->Physics->Simulation->Default Degrees Of Freedom).

The project runs fine (the cubes shake a little which is OK to me) on Windows and iOS, but when running on Android (4.4.2 in my case), the cubes shake more violently and the column collapses. The problem goes away if the “Default Degrees Of Freedom” is changed back to “Full 3D.” Is this a bug? Thank you.alt text

The problem seems to go away with version 4.16!
