Pre-Repair Checklist: Confirm the Screen Issue Safely
Before starting any repair, inspect the phone for obvious signs of liquid damage, deep impact points, or loose components around the display frame.

Gather the correct tools, including a precision screwdriver set, plastic prying tools, adhesive-safe tweezers, and a heat source suitable for loosening screen adhesive. If the device has a fragile back cover or weakened frame, keep extra padding handy to prevent further stress during opening. Finally, back up any important data if the phone is partially functional, since repairs can require powering down and handling internal components.
Parts and Tools Checklist: Get the Right Replacement Assembly

Follow a careful opening sequence by warming the edges to soften adhesive, then gently lift without forcing, especially near the side buttons and speaker areas. Disconnect the display-related flex connectors in the correct order, and take note of any brackets or shielding that must be reinstalled. When removing the old screen, inspect the frame for broken clips, bent connectors, or torn adhesive remnants that could interfere with a proper seal.
Install the new assembly by reconnecting flex cables firmly and evenly, ensuring no cable is twisted or under tension. Place the screen in position before fully sealing, then do a quick functional test to confirm image clarity and touchscreen responsiveness. Check key touch areas like corners, edges, and swipe zones, since these are common failure points if the digitizer flex isn’t seated correctly. If the screen shows flicker, no touch, or incorrect color, stop and re-seat the connection rather than pressing everything down immediately.
