Instructions for use: 1. Due to the different positions of the back cover with varying force capacity, it is recommended that the camera module on compatible models can be used directly for repair. (It is recommended to use after removing the camera, face ID, battery, and motherboard) 2. It is recommended to adjust the rear end spring for the glass back cover of other models, and loosen the rear end cover to adjust to proper strength before use, so as not to damage the back cover. 3. Do not use a screen prying tool to pry the edge of the glass back cover. 4. Pay special attention not to damage the wireless charging coil located in the middle of the glass rear shell.
