"Absolute World Position" not working in Mobile

Hi,

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.
