SmartDevil SmartPull: The Applicator, One Small Bubble and a Spare-Sample Test

Installing a screen and camera cover before trying a separate protector's resistance.

Article published November 4, 2026.

I change my phone's wallpaper before starting because the old one already looks as though it has bubbles. That is not the best background for judging a screen-protector installation.

Clean the phone, then use the applicator

The SmartDevil kit includes spare protectors, camera covers and cleaning accessories. I work through the wipe, cloth and dust stickers, then place the applicator and pull the lower tab.

After giving the protector time to settle, I remove the applicator and top film. There is a small bubble in my installation, which I push out. That actual result is more useful than promising a perfect fit every time.

The camera cover is another piece

I clean around the rear cameras and fit one of the supplied covers. That completes the installation shown on the phone.

I then take a spare protector for the separate resistance demonstration, rather than treating the fitted phone as the test sample.

What happens to the spare

I bend and work at that spare and report that I cannot get it to crack in the recording. I also describe no visible marks from the scratch attempts, while the adhesive begins to look different after the repeated bending.

Those are the informal observations in this video. They do not prove that the product is unbreakable or that a phone is fully protected from drops and impacts.

SmartDevil supplied the kits. The original product link is below for the current model and fit.
