How to Replace a Smartphone Screen at Home

Tools & Parts Needed

1

Power Off the Device

Hold the power button and slide to power off completely. Disconnect from the charger.
2

Apply Heat to the Screen Edges

Use a heat gun or hair dryer on low for 30–60 seconds around the screen perimeter to soften the adhesive.
3

Use the Suction Cup to Lift

Attach the suction cup to the centre of the screen and pull upward gently to create a small gap.
4

Insert the Spudger and Slide

Slide the spudger around all four edges to separate the adhesive. Work slowly — don't force it.
5

Always disconnect the battery flex BEFORE the display flex — a live battery and a slipped tool against the logic board is how phones get bricked.

Disconnect the Screen Cables

Lift the screen carefully, locate the ribbon cable connectors, and unclip them from the motherboard.
6

Remove the Old Screen

Set the old screen aside. Inspect the frame for any debris or leftover adhesive.
7

Connect the New Screen Cables

Connect the new screen's ribbon cables and press each connector until it clicks into place.
8

Test Before Sealing

Power on and test the new screen for brightness, touch, and colour before applying adhesive.
9

Seal and Press Into Place

Apply adhesive strips to the frame, align the new screen, and press firmly for 2 minutes.

Work on a clean, well-lit surface to avoid losing small screws.

Do not apply excessive heat — it can damage the OLED or LCD panel beneath.

Disconnect the battery connector before removing the screen on some models.

If you see smoke or smell burning, stop immediately and disconnect the battery.
