What's wrong with mobile lightning?

What’s wrong with lightning on mobile? I started using UE4 a week ago and I want to create FPS horror with really nice graphic (targeting high-end devices). So I created a character, small house and a flashlight (spotlight) and baked lightning (stationary), in editor it looks great but when a built and ran it on my device I realised that lightning is completely broken, only directional light cast shadows (very poor shadows), pointlights don’t cast it at all and spotlight (flashlight) is completely dissapear! Is UE4 still doesn’t support mobile spot/pointlight shadows and lightning? Before UE4 I worked in Unity and there all kinds on shadows/lights are supported on mobile and working smooth on my middle-end device. So what’s wrong with UE4 lightning on mobile?
