Xiaomi Poco F3 Screen Replacement

Prepare an iOpener by heating it according to the manufacturer's instructions.

Apply the iOpener to the rear glass for at least two minutes to loosen the adhesive underneath, taking care not to overheat the phone.

• As an alternative, use a hair dryer on low heat or a heat gun at a safe distance from the device.
• A hot plate may also be used, but keep it away from direct contact with the screen and internal battery components.

Secure a suction handle to the right edge of the rear glass as close to the edge as possible.

If the rear glass is cracked, the suction handle may not stick — try lifting it with strong tape or superglue in place and allow it to cure before proceeding.

• Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
• In case of trouble, apply more heat to further soften the adhesive. Be careful not to overheat by following the iOpener instructions.
• Insert an opening pick into the created gap.

• Slide the opening pick to the top right corner and slice the adhesive.
• Leave the opening pick in place to prevent the adhesive from resealing.

Insert a second opening pick at the top right corner.

• Slide the opening pick down to the bottom right corner, slicing the adhesive.
• Leave the opening pick in place to prevent resealing of the adhesive.

Reheat the adhesive for 1-2 minutes with the iOpener.

• iSclack or similar tool, insert at bottom right corner.
• Slide the tool along the phone's bottom edge to cut adhesive.
• iSclack in place, avoid re-sealing adhesive.

Insert a fourth opening pick in the bottom left corner of your phone.

• Slide the opening pick along the left edge to slice the adhesive.

• Position a new opening pick at the top left corner.

• Work the opening pick along the top edge of the rear glass, slicing any remaining adhesive.

Remove the rear glass.

• Clean affected areas with isopropyl alcohol (at least 90% concentration) before reapplying adhesive.
• Secure new rear glass using pre-cut adhesive or double-sided tape.
• Apply steady, strong pressure to the phone for several minutes after installation to ensure proper adhesion.

Using a stack of heavy books can aid in forming a good bond between the glass and the adhesive.

• Remove ten Phillips screws, 3.4 mm long.
• Additionally, remove one Phillips screw, 1.5 mm long.

Do not separate the motherboard cover from the board completely.

• Insert the tip of an opening pick under the bottom left edge of the motherboard cover.
• Use the pick to lift up the motherboard cover and release the plastic clips holding it in place.

Position your fingers under the motherboard cover and gently lift it upwards.

Heat an iOpener and apply it to the screen.

• Allow the iOpener to heat the screen for at least two minutes.

Secure a suction handle to the screen's bottom edge.

If the phone is cracked, try using strong tape or superglue on the suction handle for better adhesion.

• Lift the screen with the suction handle, creating a small gap between it and the frame.
• Insert an opening pick into the gap.
• If needed, reapply heat to soften the adhesive further (refer to iOpener instructions for guidelines).
• Slide the opening pick to the bottom right corner.

Insert a second opening pick into the gap, sliding it down towards the lower left corner.
