Hey thanks for the reply :)
I figured out that it was on certain builds of android even when you have
images that are in the power of two, once you pull them from a stream and
pass them by reference some how theres a chance that they will be resized.
I went through and made sure that anywhere I was making a copy by reference
I used
BitmapFactory.Options ops = new BitmapFactory.Options();
ops.inScaled = false;
And this prevents the system from messing with the images.
