Please make sure your model matches before making a purchase, as incorrect models will delay your use of the phone. 【INCELL Screen】: The price is very affordable, but unlike the original, INCELL's screen has no fingerprints, is thicker, has a smaller screen size than the original, and has no curved edges. It will be higher than the frame, but it will not affect use. If you are concerned about this, you can purchase original products in our store. 【Quality Assurance】: All products undergo strict quality inspection before shipment. Ensure that the screen is free of scratches, dead corners, pixels or lines, smooth to the touch, and 100% intact and undamaged. 【With Frame 】:Screens with frames are easy to install and resistant to damage. If you opt for a "screen with a border," the installation risk is relatively low. 【 After sales Service 】: 1. Please check if the screen is damaged or broken after receiving the package. 2. Please test the screen before installing it. If there are any problems with the screen, please contact me in a timely manner.
