Introduction
Use this guide to replace the screen protector on your Motorola Razr 40.
Your foldable phone's screen is much softer and more delicate than non-folding glass screens. If the screen protector is damaged or peeling, it might need a replacement before it damages the screen underneath.
This guide shows how to replace the protector using an alignment adapter and a film roller.
-
-
Completely open your phone and unplug any cables.
-
Place your phone in the alignment adapter screen-side up, with the charging port facing the raised posts.
-
-
-
Use scissors to cut a small square (about the size of your thumbnail) out of your replacement screen protector liner, just between the two long cutouts on the bottom edge.
-
-
-
Slide the sharpest corner of your shim under one of the top corners of your screen protector.
-
-
-
Insert your shim deeper under the corner of the protector until you can grip it with your fingers.
-
-
-
Have your replacement screen protector and roller within reach—you'll be holding the protector up with one hand and won't be able to let go to reposition or grab a tool.
-
Orient the replacement protector so that the oval cutout is on the top right, and the long cutouts are toward the bottom of the phone.
-
-
-
Use a pipette or syringe to apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to your screen.
-
Use a microfiber or lint free cloth to wipe away any smudges or dust.
-
-
-
Hold the replacement screen protector with its liner pull tab facing down. Keep the film facing down to prevent dust from settling onto the sticky side.
-
Peel and fully remove the protective liner from the underside of the protector.
-
-
-
Slide the top circle and oval cutouts over the hooks on the upper alignment posts.
-
Gently pull the replacement protector over the screen and onto the lower alignment posts. Don't let the film touch the screen just yet.
-
-
-
Hold the protector tight over the lower alignment posts.
-
Use the roller to firmly roll the protector onto the top half of the screen, starting from the top edge.
-
When you reach the middle of the screen, lift the remaining half of the liner to a 45-degree angle.
-
Increase pressure on the roller and slowly roll across the hinge area of the screen.
-
When you pass the middle of the screen, lower the liner and finish rolling the bottom half of the protector onto the screen.
-
-
-
Use the squeegee or a plastic card to press the top and bottom edges of the protector onto the screen.
-
Press around the perimeter of the screen, working out any bubbles toward the edges as you go.
-
-
-
Peel the top right corner of the large liner away from the screen to separate it from the screen protector.
-
-
-
Work down the long edge of the screen, peeling up the edge of the liner as you go.
-
Once you reach the bottom of the screen, fully peel the liner off and remove it from the adapter.
-
-
-
Use a microfiber or lint free cloth to wipe the screen protector and rub out any streaks or imperfections between it and the screen.
-
Work out any small bubbles by wiping toward the edges. If there are any large bubbles, the screen protector didn't adhere properly and needs to be replaced.
-
-
-
Use your squeegee or a plastic card with a cloth to firmly rub along the perimeter of the screen protector to fully secure the edges to the screen.
