UE5.7.4 Lumen Has No Shadows on Android Tablet

I’m a complete beginner with Unreal Engine 5. With the help of AI, I just created a new project. My goal is to try using Lumen lighting on a relatively new Android tablet powered by a Snapdragon 8 Gen 3 chip.

In the editor, my test scene looks like this

but when I run it on the actual device, it looks like this

It appears that lighting is present, but there are no shadows. I’m using a point light source.

I followed AI guidance and verified all settings related to shadows and Lumen, including Vulkan SM5, Support Vulkan Desktop, etc., and everything seems correctly configured. I’m using the latest version, 5.7.4.

However, I saw some posts on Reddit claiming that Lumen on Android simply doesn’t show shadows and that this might be a bug. Is that true, or did I miss something in my setup?

Thanks in advance for any help!
