Hey, do you know if the outer (glossy) panel is removable (changeable) or permanently laminated to the screen?

Piotr Klim -

It is a fully laminated display module.

Andy Zeng -

Excellent, thanks for this! Is it possible to replace the built in camera with a more modern one? Any thoughts in this?

Scott Martin -

I think it is impossible since the camera module is highly integrated to the main board, there are also some special pins to route the audio signals from the camera module to the audio chip on the main board.

Andy Zeng -

Hi Andy,

Thanks for the tear down, With the bezel is it just clipped on and just requires the use of a spudger to get it off?

Mat MacEley-Young -

Yes! I just took it off with my hands

Andy Zeng -

The camera being on the same module as the mic, if my mic does not work it would rather come from a softaware problem ? right ?

Thanks for this anyway.

fab -

How easy is it to replace the front/rear bezel? Mine is cracked on the bottom corners of both sides.

And I’m having a hard time discerning how to simply replace the front bezel part.
