shadow issue - scratches on shadows on Android (Samsung Galaxy Tab S)

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.

I'm seeing this too. Surprised it hasn't been fixed.

Seeing the same with shadows on Samsung Galaxy Note 5, Unity 5.3.5f1

I 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. This thread http://answers.unity3d.com/questions/673703/strange-flickering-on-mobile-using-the-directional.html#answer-673716 helped and had similar problem.
