The sole screen serial number can not be read, thus, 3uTools can not verify if the device screen is replaced or not. The display accessories assembly includes the LCD display, touch screen, front camera, earpiece, sensor and other accessories. Most repair men would not replace the camera from old assembly to the new assembly, because it may easily get damaged to dismantle the assembly. In short, if a repair man want to replace the display accessories assembly, he may need to replace the whole one.
Therefore, if the factory value of front camera does not match to the detected value, the screen display may be changed.
