"Absolute World Position" not working in Mobile


Absolute World Position is not working properly on Android.
(You can check it in Mobile Preview.)

We have found the same issue, UE-25532, and this bug is being reproduced.
([WorldPosition node output broken on mobile - Rendering - Unreal Engine Forums][1])

The current engine is 4.20.1.

I have some similar results on few “old” android devices with open gl es 2.0. I think this will work well only on 3.1 or so.

Better use simple customized UVs with tiling/scale multiplier.

Galaxy s8 also has the same symptoms.
Also in open gl es 3.1.
