What's in the box
Every Armorex protector ships with everything the installation needs: the protector itself, an alcohol pad, a dry microfibre cloth, and a dust-removal sticker. You do not need to buy anything extra, and you should not need household glass cleaner — most contain ammonia, which damages the oleophobic coating on a phone screen.
Set aside five quiet minutes. Almost every failed installation is a rushed one, and the single biggest factor in the result is how clean the screen is at the moment the glass touches it.
Step by step
Wash and dry your hands first
Skin oil is the most common cause of a hazy patch under a new protector, and it transfers the moment you touch the adhesive side. Dry hands completely — a damp fingerprint on the underside will show as a permanent cloudy mark.
Pick a low-dust room and let the air settle
A bathroom shortly after a hot shower is the traditional trick: the steam pulls airborne dust down. Avoid anywhere with carpet, open windows, or a fan running. Give the room a couple of minutes of stillness before you open the packet.
Remove your old screen protector, if you have one
Lift a corner with a fingernail or a thin plastic card and peel it off slowly and at a low angle, rather than snapping it straight up — this keeps the old adhesive from leaving residue. Cleaning and applying a new protector directly over an old one, or over leftover adhesive, is what causes bubbling and edge lift later.
Clean the screen in two passes
Use the alcohol pad first to lift oil, then the dry microfibre cloth to remove any residue and streaks. Let the screen dry completely — applying glass onto a screen that is still faintly damp traps moisture that shows as rainbow patches.
Lift the last dust with the sticker
The screen will look clean and still have specks on it. Press the dust-removal sticker onto the screen and lift straight up, working across the whole surface. Do this immediately before applying, not several minutes earlier.
Align before anything touches down
Hold the protector just above the screen and line up the earpiece cutout and the edges before any part of it makes contact. On a folding phone, check that the glass sits inside the bezel with no overhang — an overhanging edge is what stops the phone closing flush.
Drop from the centre, don't press down
Once aligned, lower the middle of the protector onto the screen and let go. The adhesive pulls itself outward from the centre on its own. Pressing the corners down first is what rolls air inward and creates bubbles.
Push out what's left, from the middle outward
Any remaining air moves with light pressure from the centre toward the nearest edge, using the microfibre cloth or a card. If a bubble refuses to move, there is dust under it — lift that corner, remove the speck with tape, and lay it back down.
Wipe down the installed glass with the alcohol pad
Once the protector is down and the bubbles are out, give the top surface a final wipe with the alcohol pad to remove the factory residue tempered glass ships with. Follow with the dry microfibre cloth to leave the surface clear and streak-free.
Common installation questions
Why does my screen protector have bubbles?
Almost always dust. A speck trapped under tempered glass holds the glass off the screen and air fills the gap around it, which is why the bubble does not push out no matter how hard you press. Bubbles with no dust at the centre are air that was rolled in during application, and those usually do settle on their own within a day or two.
Can I remove and reapply a tempered glass protector?
It is not recommended. Once the adhesive has been exposed, dust settles on it within seconds, and pressing the glass back down traps that dust underneath as a permanent speck or bubble — a reapplied protector rarely sits as flat as it did the first time. Lifting one corner during installation to lift out a speck is fine, but a protector that has come fully off should be replaced rather than put back on.
How long before the edges stick down fully?
Tempered glass adhesive continues to settle for roughly 24 hours. Small edge gaps immediately after application often close on their own overnight. If an edge is still lifted after a day, there is usually dust or a fingerprint underneath it.
Do I need to clean the screen if the phone is brand new?
Yes. A new phone still carries a film of oil from handling and from the factory sticker, and dust settles on it within seconds of unboxing. Clean it the same way you would an older phone.
If it still isn't right
A protector that will not sit flat after a careful second attempt is worth telling us about rather than living with. Email info@shoparmorex.com and describe what you are seeing. Our return policy covers defective items for 30 days.
