_Time shader code not working on Mali 400

Unity Engine

I’m using _Time in my shader to animated UV.
Running the code for more than 5minutes, the value in _Time.x will remain constant.
This happens on any devices with Mali 400. i.e Samsung S3 and Tab 8

i’m using Unity 4.6.2f1

thanks

_Time works OK for me. You’ll probably get an answer if you post your code in the shader forum.
