Tempered Glass Installation Guide Step 1: PrepareOpen the screen protector package and set everything up on a clean, uncluttertable. You should have an alcohol wipe and a microfiber cloth in addition to the glass protector. Make sure your device is turned off. Step 2: Clean Your ScreenUse the alcohol wipe to thoroughly clean your screen, and then use the microfiber cloth to give it one last polish for good measure. Step 3: Remove the Protective LayerThere’s a protective plastic film on one side. Remove it to expose the adhesive side of the glass, but be sure to hold it by the edges so that you don’t leave fingerprints on the surface. This side will be going face down on your device screen.Step 4: AlignmentMake sure to align the glass with the display portion of your screen. The glass should line up evenly with the front speaker and home button, and it should run parallel with the screen length-wise.Step 5: Press It OnOnce the glass protector has been properly aligned, carefully lay it down on the screen. If you make a mistake and the glass looks off-kilter, you can gently lift it up and realign it. Then, once the protector is on the screen, give it a soft press in the center and allow the adhesive surface to grip to the screen naturally. Step 6: Final TouchesIf there are any bubbles remaining -- and there may not be -- use the cloth provided to gently smooth them toward the edges of the glass protector.
