Supershieldz TPU Screen Protector Film
Sometimes you need a protector that behaves like a second skin rather than a rigid sheet of glass. This film version is thin and pliable, making it an excellent choice for users who want subtle protection that does not interfere with the ultrasonic fingerprint sensor.
Because it is made from thermoplastic polyurethane, it absorbs minor impacts and resists peeling at the edges. It acts like a flexible shield that bends with the curve of your phone. You should be aware that because it is a soft film, it may develop small indentations over time if you press down with a sharp fingernail or stylus.

Frequently Asked Questions
Does the screen protector block the S Pen?
Most protectors will not interfere with the S Pen functionality at all. Because the S Pen uses an electromagnetic digitizer, it detects input through the glass quite well. Just ensure you are not using an excessively thick layer of tempered glass, which could theoretically affect pressure sensitivity.
Can I remove a glass protector without damaging my screen?
Yes, but you should take your time. Use a thin, flat tool like a guitar pick or a credit card to gently pry up a corner. If the protector is shattered, use a piece of clear tape to hold the shards together so they do not fall into the screen or your eyes during removal.
Why do bubbles appear after a few days?
Bubbles usually show up because of trapped dust or because the adhesive is not sitting flush against the curved edges. If you see a bubble near the border, it might be due to a case pushing against the protector. Clean the screen thoroughly with microfiber before you start to avoid these issues.
Will a screen protector hide existing scratches?
A wet install film can actually fill in minor scratches and make them look less noticeable. Tempered glass does not really hide deep marks, but it covers them so you do not feel them when you swipe. Neither option will magically erase a deep gouge in the original display glass.
How often should I replace it?
You only need to replace the protector when it becomes cracked, chipped, or scratched enough to annoy you. If the edges start to peel or the touch sensitivity drops, it is time for a fresh one. A well maintained screen protector can easily last the entire lifespan of your phone.
