What is the “back glass” for the Poco X3 Pro

• The back glass is the exterior rear panel of the phone: the piece covering the smartphone’s rear body, typically over the battery, motherboard, and camera module.

• On many modern smartphones (including the Poco X3 Pro) this panel is made of glass (or glass-like material) rather than plain plastic, for premium feel and better aesthetics.

• This part also holds or aligns the camera lens module, flash, and other elements, and may incorporate aesthetic finishes (color gradients, textures) or logos.
