Why shadow not rendering correctly on mobile platform?

I made a simple 3d project it works good on my android phone but the problem is no shadows on mobile platform if i come closer to an object it casts shadow but when i am a little far away from that object it doesnt cast shadow but on my pc i didn’t face this problem shadows are working great i tried changing shadow distance from quality setting but still the same any ideas on how to fix it?

Go to Quality Settings and change shadow distance . Edit → Project Settings → Quality.

@awts202 i tried that already but still the same
