Jagged Dynamic Shadows on Android UE4.

Hey guys I’m having trouble with dynamic shadows on mobile. I’m making a game for mobile on UE4 2.7 and using Modulated Shadows with Stationary Directional Light, the shadows look great in the engine Mobile Preview.


but when I run it on my device I get really jagged square shadows and I have no idea why or how to solve this.

I am attaching screenshots of my light settings for reference



I have already tried increasing the shadow resolution and Lightmap resolution on the surface but it made no difference. Tried to increase the render resolution with ‘DefaultDeviceProfiles.ini’ in Engine/Config folder and still no improvement.
I am completely lost on this issue please help me with this.
Thank you.
