Introduction

This guide will walk you through the process of replacing a faulty LCD screen and digitizer assembly in a Motorola Moto G4 Plus phone.

This guide is for replacing a complete display assembly, which includes the display frame. Your replacement part should look like this. If you purchased a bare display, you must complete additional disassembly steps, which are not covered by this guide.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

Insert a fingernail or a spudger into the notch on bottom edge of the phone near the charging port.

  • Peel the black pull tab from battery and pull slowly but firmly to separate the battery from the frame.

    • A few drops of high concentration (90% or higher) isopropyl alcohol along each side may help soften the adhesive.

    • If the pull tab breaks, use a spudger to gently pry around the edges of the battery until it comes loose.

  • Don't deform or puncture the battery—it can catch fire and/or explode if damaged.

  • Never reinstall a damaged or deformed battery. Replace the battery.

Does anybody know, what the black tape covering the metal cans an the battey is made of? It seems to have a heat insulating effect.

  • Remove the battery.

  • To install a battery, orient the new battery such that the wires exit near the bottom of the phone, and the battery connector is on the motherboard side.

  • Clean off any adhesive residue which may prevent the battery from sitting flush against the frame. Use a few strips of adhesive included in the battery kit or some double-sided tape to secure the battery to the frame.
