Hey there,
I have some problems with shadows from a directional light (forward rendering).
I uploaded a picture of this problem.
This are just standard mobile-shaders (spec + diff) but the same problem appears with the legacy shaders.
I am confused, because the problem only occurs on the Samsung Galaxy SM T800.
I think it´s not about quality settings, there is (for testing) just one enabled:
Pixel Light Count 2
Texture Quality Full Res
Anisotropic Textures Disabled
Anti Aliasing Disabled
Hard Shadows Only - High Resolution - Stable Fit
Shadow Distance 70 - No Cascades
Hope someone could help me or has a solution. Maybe it is about the qualcomm Snapdragon 800 chip???
Thanks in advance

Update: playing around with the bias settings gives me now better results. The stripes are now only where shadows actualy should be, but they are sadly still there.
– Elias_MinorI'm seeing this too. Surprised it hasn't been fixed.
– AmazingRussSeeing the same with shadows on Samsung Galaxy Note 5, Unity 5.3.5f1
– FozzI was seeing something similar but not as bad. I set my bias to .25 on the light (was 0) and that fixed it for me on Samsung Galaxy Note 4.
