of the battery and lift upward
Remove
the SIM card by first pushing the card slightly out of its housing, then
pulling it the rest of the way.
Remove
the sixteen 4.0 mm Phillips #00 screws securing the midframe to the display
assembly. Grasp the cap of the S Pen and remove it from its slot in the
midframe.
Insert
a plastic opening tool between the midframe and the display assembly. Work the
plastic opening tool around the perimeter of the phone to break the adhesive.

is still held together with adhesive.

a plastic opening tool to loosen the clasps around the battery housing.
Push
on the battery housing to separate the midframe from the display assembly. You
will have to apply a reasonable amount of pressure to separate the two parts.
If your new midframe does not come with a headphone jack assembly, you'll need
to transfer the one from the old midframe into the new one. It can be pried
loose with plastic opening tools, as it is held in place with several plastic pins.
Remove
the two 2.9 mm Phillips #00 screws.
Use
a set of tweezers to remove the two antenna cables.

a set of tweezers or the flat end of a spudger to disconnect the two ribbon
cable connectors.

camera to the motherboard with your fingers.

lens surface is especially treated to reduce reflection of light. As incorrect
maintenance may impair the performance of the projector, take care with respect
to the following:
# Wipe the lens gently with a soft cloth such as a cleaning cloth or glass cleaning cloth.
# Stubborn stains may be removed with a soft cloth such as a cleaning cloth or glass cleaning cloth lightly dampened with water.
# Never use solvent such as alcohol, benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning cloth, as they will damage the lens surface.
Cleaning the cabinet
# To remove dust from the cabinet, wipe gently with a soft cloth. If dust is persistent, wipe with a soft cloth slightly moistened with a diluted mild detergent solution.
# Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide.
# Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the screen surface and cabinet material.
