Does the XD+ uses a different lcd panel? The screen definitely looks different.
On a regular XD i have my brightness set to 100%, auto brightness is off and it's almost the same as my smartphone 75% screen brightness.
On my XD+ at 100% brightness is around 50% on my smartphone, so it's a huge difference.
Also it maybe just me the screen seems to have a very light blue tint to it, thou this may be just me.
Any clues? I have installed clean rom from Black Seraph.
