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 the 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.

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.

If your touchscreen feels less responsive after applying the screen protector, try the following:

1. Clean both the screen and your fingers with a soft cloth to remove oil, sweat, or lotion residue that may affect touch sensitivity.
2. Go to your phone’s “Display” or “Accessibility” settings and increase the touch sensitivity.
3. If you are using a privacy tempered glass screen protector, it is about 0.1 mm thicker than regular clear screen protectors and may slightly reduce touch sensitivity. If you require better responsiveness, we recommend switching to a tempered glass screen protector without privacy control.

Issues with the edges not sticking are usually caused by one of two factors.

1. White edges or bubbles – These occur because the edges of your phone screen are slightly curved, leaving tiny air gaps after application. Press firmly along the edges to push out the air. A slight rebound is normal; just press again for a few seconds to ensure proper adhesion.
2. Case pressure – A third-party case that is too tight or has high inner edges can press against the glass and cause it to lift. We recommend using ESR cases, which are precisely designed for perfect compatibility with our screen protectors.

Yes. Each UltraFit kit includes an alcohol wipe and a cleaning cloth to help prepare your screen before application. ESR screen protectors feature a dust-repellent adhesive, so when you place your phone in the tray, pulling the tab automatically removes dust from the screen. The UltraFit tray is designed to ensure perfect alignment, which significantly reduces the chances of air bubbles, resulting in a smooth, bubble-free, and dust-free installation.
