Rendering issue on android devices

As shown in above screen shots. on some android devices textures are rendering as black.
But when I try to capture screen from the device it saved it perfectly alright.

Can anyone please suggest me whats wrong ?

findings so far:
Terrain and skybox are rendering without texture (black) rest of the objects are fine properly on Nexus 4 and S3 minis

Created another demo project…having same issue on Nexus 4 and S3 mini
Steps
Create new project
import standard asset(skybox) and standard asset( mobile)
add Dawn dust skybox to edit->Render setting
Main Camera Clear Flags = Skybox
Build android apk

Fixed!!
Unity Update 4.1.3
