shadows glitch ?

hello everyone,
I’m new here and I started my journey with Unity3D only recently and made an apk for my phone … I already searched everywhere for the answers but problem with shadows not showing or showing partialy still occurs leaving me puzzled. in Unity everything looks fine but on my device it looks like a graphic glitch. Shadows appear only on the bottom of the scene. I digged all options in publish settings and also quality settings but with no effect… really apreciate if someone would give me a hint on this… thank you in advance !!!

I already solved the problem. You can close the threat :slight_smile:
