Screen Assembly

Leaving screws inside the device may damage internal components, such as the

battery. When assembling, be extra careful not to leave any unassembled screws

inside the device.
Before attaching the back cover, make absolutely sure that there are no screws,

miscellaneous parts, or other foreign objects on the inside of the device (among

the battery, PBA, etc.).

Remove the inner vertical transparent film on center of the new screen adhesive tape.
