I made a game and added particles using the AppGameKit Particle Editor but on some Android phones there was an error like this

The error occurs when the game is run on my Android 5.1 cell phone while on the other Android 5.1 phones there is no error and the game runs smoothly as usual
is there a way to solve this problem?

That's a weird one.
It's in the vertex shader and 5.1 is old, which gives me one idea that maybe helps. Sending you a PM with a quick change. Hopefully that helps. If it does I'll make an official update with it.
If it doesn't help, then it's old hardware that doesn't support texture reads in the vertex shader, in which case GPU particles are not possible on that phone due to the hardware limitation.

So the Particle editor and code uses custom shader ? (Don't have it yet ^^)
Cause I can't find default shader that uses VTF's in AGK.

Also shouldn't it be texture2DLod instead of texture2D as Vertex shader can't know which Lod to use so one need to choose the lod level explicitly ?
But I'm just guessing as I have no info about the shader.

Yep it should, some compiler versions won't catch it. Saw it too, the fixed version is out in testing. Mistakes were made. Blame has been assigned (to me), heads are rolling.
This is the first device reported that has the problem, we will see what happens. Hoping for the easy fix.

Everything but not the head...I need your head if I come up with some special shader questions
