If statement not going through?

TL;DR My app is working on certain phones, but not on others?

My app uses the following code to compare images on imagebuttons:

(onCreate):

  redsquare = getResources().getDrawable(R.drawable.redsquare);
        bitred = ((BitmapDrawable) redsquare).getBitmap();

(onClick. v is the view clicked.):

ClickGround = v.getBackground();
        BitClick = ((BitmapDrawable) ClickGround).getBitmap();

Then, later on in the onClick, I check if the user clicked on the redSquare by doing this:

if (BitClick == bitred) { //Make sure it is the red square that user clicked
}

The wierdest thing is happening though. I have tested it on my emulator and HUAWEI phone, and it works fine. When I tested it on my other phone (lg g3), but it doesn't go through the if statement even when I clicked on the red square! Why are the results different? Is the image somehow being messed up in my phone?

Thanks,
