Shadow peter-panning problem in mobile

Unity Engine
1

I know there are some tricky about the shadow acne and peter panning. I do not mind the bad effect of shadow acne so I set the Shadow Bias value closed to zero. When it plays in Editor, there is no problem. When I export to android platform, whatever I set the bias value, 0.1, 0.05, 0.01 or even 0, the shadow shows disconnect between my leg object and the ground. I have tried all quality settings and shaders. However, the problem only exists in mobile platform, it shows perfectly in Unity Editor, so I am curious whether it is my mobile problem (Samsung Galaxy Note3, there is a serious shadow problem in previous version of Unity), or only the problem in my setting.

No problem in editor:

Anyone solved it before?Any recommendation is welcome.

Are you using a 24 bit depth buffer? If not, try that.

I checked that it is set by default.

Sad to say it might be a hardware/driver issue. Can you try on iOS or a different Android device?

You are right. It only happens in Samsung Galaxy Note3. There is no problem in Galaxy S4. I think it is an extension of the shadow issue which just said to be fixed in version 4.5.

Report a bug regardless just in case if you can to be doubly sure it’ll get fixed for you. Hopefully.

I navigated the unity site for an hour, still don’t know how to report a bug. So sad …

The problem still exists in 4.6b17

It’s done within the unity editor → report a bug
