How a Galaxy display is built
On most Galaxy models, the cover glass, touch layer and OLED screen are not only bonded to each other but also firmly attached to the metal frame that forms the front of the device.
That means the display is not a part that can be taken out and replaced on its own. This is why we always replace the display and frame together on Samsung phones.
Apple solves it differently: there, the display is a separate assembly that can be separated from the frame. That is where the price difference many people notice comes from.
