NIMASO films have been well received for their ease of application, but the NIMASO Service Center occasionally receives questions such as, "Air bubbles appeared while I was applying the glass film."
Today, we will show you how to apply stickers without trapping air bubbles, and what to do if air bubbles do form! Some of these tips may already be familiar to you, but we will also explain the most foolproof way to deal with the problem, so please read to the end.
Standard solution 1: Prepare the environment for application
No matter how well you clean your room, there is often invisible dust floating around, and dust can cause insufficient adhesion and air bubbles. We recommend pasting the sticker in the bathroom, as it is a closed room with little air flow and humidity makes it difficult for dust to fly around. If you find it difficult to work in the bathroom, try to avoid places where the air conditioner or fan blows.
Standard method 2: Wash your hands before applying the sticker
It may seem obvious, but it's actually surprisingly important. Your hands are covered in invisible oils and dust. Just in case, make sure to keep your hands clean as well as your work environment!

Common Solution 3: Clean the Display
NIMASO's glass film always comes with an accessory for cleaning the display. The reason is that fingerprints, dirt, and dust caused by static electricity tend to stick to the iPhone display, and if they are not removed, there is a high possibility of air bubbles appearing. In particular, it is very difficult to remove air bubbles caused by dust.
So, before applying the NIMASO glass film, wipe it clean with the wet sheet and microfiber cloth that come with the NIMASO glass film. After that, peel off the dust sticker and lightly tap the LCD part. We recommend that you carefully remove dust with the dust sticker even after attaching the guide frame.
If air bubbles still appear...
Don't worry, the air bubbles will often go away on their own! In most cases, they will go away if you leave it for 1-3 days, so we recommend that you do not forcefully peel it off and instead leave it for a while.
If the issue persists, please contact NIMASO Customer Support !
But if there are bubbles caused by dust, you will have to reapply it.

NIMASO's recommendation: A foolproof application method
Is there a way to avoid worrying about dust when applying the sticker?
To be honest, no. However, the new product that NIMASO has developed since this fall can prevent dust from entering to a certain extent. It may be introduced first in products compatible with the iPhone 14 series (tentative).

How does NIMASO's new glass film work to prevent dust?
The improvement to the new NIMASO product is not the glass film, but the guide frame. The improvement to the guide frame has made the application process easier.
Unlike conventional NIMASO products, you can simply clean the display, place the guide frame on top, and then the glass film will be automatically attached. In other words, once you place the guide frame, the installation of the NIMASO glass film is complete! Easy, right?
For those considering purchasing the iPhone 14 series (tentative), NIMASO recommends its new glass film with guide frame.

They put a lot of effort into the guide frame, but will the quality of the glass film be compromised?
You don't have to worry about that. At NIMASO, we value the quality of our glass film more than anything else, so we produce our glass films to the highest standards in the industry.
