Replacing the Screen on the OnePlus 12 Pro

Replacing the Screen on the OnePlus 12 Pro – Complete Guide + 10 Must-Know Tips


Introduction: Why Screen Replacement is Tricky

The OnePlus 12 Pro is packed with premium hardware, including a stunning 120Hz LTPO AMOLED display with curved edges and high touch sensitivity. But its design — including a sealed glass back, in-display fingerprint sensor, and delicate flex cables — makes screen replacement complicated.

If your phone’s screen is cracked, unresponsive, or bleeding pixels, follow this guide for the safest repair process.


When Should You Replace Your OnePlus 12 Pro Screen?

Consider a replacement if:

  • Your screen has deep cracks affecting touch
  • The display shows black spots or ghost touches
  • The screen is unresponsive or flickers
  • There’s no display even though the phone powers on
  • Your fingerprint scanner stops working due to damage

Delaying replacement may lead to further internal damage or battery drain from display malfunction.


Tools and Parts You’ll Need for a Safe Replacement

Tool / Material Purpose
Heat gun or hot plate Softens adhesive on back panel
Suction cup & plastic picks Opens the device without damaging the frame
Precision screwdriver set Removes internal screws (Torx, Phillips)
Plastic spudger & tweezers Safely disconnects cables
Isopropyl alcohol (≥90%) Cleans adhesive and residue
Replacement AMOLED screen OEM preferred for best results
Adhesive strips / glue Resealing the phone

OEM vs Aftermarket Screens: What You Should Know

Feature OEM Screen Aftermarket Screen
Display quality True-to-original color and brightness May be dimmer or inaccurate
Touch sensitivity Fully compatible with in-display sensor May affect fingerprint accuracy
Refresh rate Supports full 120Hz Often limited to 60Hz or has ghosting
Durability Tested to factory standards Often uses cheaper materials

For the OnePlus 12 Pro, an OEM screen is highly recommended to preserve the display experience and device integrity.


OnePlus 12 Pro Screen Features and Design

  • 6.82” LTPO AMOLED, 120Hz refresh rate
  • HDR10+ and Dolby Vision support
  • Curved edge glass
  • Gorilla Glass Victus 2
  • In-screen fingerprint sensor

The curved edges make adhesive removal and reinstallation more delicate than flat screens.


Step-by-Step OnePlus 12 Pro Screen Replacement Guide

Step 1: Power Off and Eject SIM Tray

Turn off the phone completely and remove the SIM tray to prevent electrical damage.

Step 2: Heat the Back Glass and Open the Device

Use a heat gun or hot plate around the edges. Carefully insert a plastic pick or card to loosen adhesive. Take extra care near the camera bump.

Step 3: Disconnect the Battery and Remove Internal Shields

Unscrew the midframe and shields. Disconnect the battery connector first, then display cables and any antenna modules.

Step 4: Detach Display Connectors

Locate the display flex cable connected to the motherboard. Use tweezers or a spudger to lift it carefully without bending it.

Step 5: Remove the Damaged Screen

Heat the front edges, especially the corners. Gently pry the screen from the frame. Clean leftover adhesive and inspect for bent frame areas.

Step 6: Install the New Screen and Reassemble

Place new adhesive. Align and connect the screen. Test it before sealing the back. Reconnect all cables and battery, then reattach the back glass.


10 Pro Tips to Avoid Costly Screen Replacement Mistakes

  1. Always disconnect the battery first — avoid short circuits.
  2. Use non-metal tools to avoid damaging boards.
  3. Don’t rush heating — soft adhesive = safer removal.
  4. Use OEM screens to avoid calibration issues.
  5. Avoid touching the inside of the new display.
  6. Label your screws — different lengths go in different places.
  7. Don’t over-tighten screws — can crack the board.
  8. Test the screen before sealing the phone.
  9. Replace adhesive completely, not just patching old strips.
  10. Recalibrate the fingerprint sensor if needed after replacement.

Testing the New Display Before Sealing

Before resealing the phone:

  • Check touch responsiveness
  • Confirm screen brightness and 120Hz refresh rate
  • Test the in-display fingerprint sensor
  • Inspect for any dead pixels or color streaks

This ensures you don’t have to reopen the phone if something’s wrong.


Common Issues After DIY Screen Replacement

Problem Likely Cause
No display or black screen Loose display cable or connector not seated
Touch not working Faulty screen or torn flex cable
Fingerprint sensor fails Incompatible screen or misaligned sensor
Back cover won’t sit flush Misplaced screws or adhesive too thick
Display flickers Incompatible screen or loose connector

When You Should Let a Pro Handle It

You should avoid DIY if:

  • You’ve never opened a smartphone before
  • You don’t have the tools
  • Your phone is still under warranty
  • You value display quality and longevity
  • You’re unsure about adhesive or cable handling

OnePlus screens are expensive — even a minor mistake can make your phone unusable.
