1. Clean phone camera lenses using a wet wipe, dry cloth, and dust removal sticker in the included cleaning kit. 

2. Remove the protective film from the alignment guide, align it with the lenses, and press firmly on each camera lens protector to fully apply. 

3. Remove the alignment guide, then clean the camera lens protectors using a dry cloth.

Bubbles on your device's screen protector are most likely caused by dust or air trapped between the screen and the protector. 

If air bubbles appear in the center, gently lift the nearest corner of screen protector, then release it to remove air.

For any white edge gaps, push down towards the edges. Push any air bubbles towards the edges with the microfiber cloth or ID/ credit card.

If you are still unable to remove the bubbles, you may need to apply a new screen protector. Please contact us if a new one is needed.

If the screen protector you ordered doesn't fit your device, please provide us with your device model name or number. We'll send you the correct size, with no returns necessary.

How to find your device model:

iPhone: go to Settings > General > About > Model Name/Model Number

Please send us a photo of the item you received, along with your shipping address, and we will send a free replacement.

The Tempered-Glass Privacy Screen Protector features a 180-degree privacy filter, which has a higher light transmission for a clearer display and blocks viewing from any angle greater than 28 degrees left and right in portrait mode.

If you notice that your display is a little darker after applying this privacy screen protector, increasing your phone's screen brightness will solve this issue.

However, please avoid increasing your screen brightness too much as this may cause eye fatigue and dizziness after extended periods of use.
