After a proper installation, if you see small bubbles between your InvisibleShield and the screen of your device, do not worry. That’s actually normal as it settles on your device. They should disappear in about 24-48 hours.
If they’re still there after a couple of days it could mean that some lint or dust particles found their way between your device and InvisibleShield during installation. Do not attempt to remove the InvisibleShield and reapply. Doing so will compromise the adhesive and it will not stick to your device as well.
