The big problem with curved displays – adhesive area vs Full Glue

Curved screens are impressive, but many people encounter the same problem with them: why doesn't the screen protector stick properly to the edges? Often the reason is not the phone – but the type of adhesive technology used in the screen protector.

What does "adhesive-zoned" armor film mean?

Many cheap tempered glass screens made for curved screens only have adhesive on the edges. The middle part itself is made of float glass, which means:

• The edges may start to come apart (so-called "halo effect")
• Decreased touch sensitivity
• Dust and dirt get under the membrane
• The phone screen looks blurry from the sides

This technology is cheaper to manufacture, but does not work well for curved displays .

What is Full Glue tempered glass?

Full Glue means that the glue is on the entire glass surface, not just the edges. This makes the protection significantly better:

• Doesn't fray at the edges
• Stays on curved screens
• Touch works as if it were without protection
• The image remains clear
• Air bubbles are removed more effectively

Still, curved screens are still difficult, and many users end up with hydrogel , which adapts to the curvature perfectly.

The best option for curved screens – hydrogel film

Hydrogel is not glass, but a flexible and self-healing material that adheres to curved screens without any problems. It is the best choice when you want to:

• Rimless and close fit
• No cracks or chipping corners
• Excellent tactile feel
• Permanent attachment even to strongly curved phones

But what if you want a glassy feel?

On some phones, Full Glue glass works very well, especially with small curvatures. Try the glass options here:

Summary

• Adhesive-coated glass = cheap, but almost always comes off curved screens
• Full Glue = better grip, but not always perfect
