Most people believe that tempered glass will protect their phone screens in every situation, but the truth is quite different. When a phone is dropped, the tempered glass itself breaks, leaving the screen unharmed. Sometimes, while the tempered glass is fine, the original screen cracks. The real difference lies in the quality of the glass and its fitting.

How does tempered glass work, and when does it get damaged?
Tempered glass is designed to absorb the first impact if the phone is dropped. It breaks and prevents the shock from reaching the screen. However, this is only possible if the glass is of high quality, the glue is evenly applied, and the fitting is completely airtight. If there are gaps at the edges or bubbles form during installation, the impact is directly transmitted to the screen during a drop.

Don't make the mistake of assuming that tempered glass is strong if it doesn't break.
Many vendors in the market demonstrate the strength of the glass by hitting it with a hammer. People take this for granted. But the reality is that tempered glass, which doesn't break, will transmit the shock to the screen. This increases the risk of breaking the screen. A tempered glass protects the screen by cracking on its own in case of a drop.

How to choose the right tempered glass?

Find glass made specifically for your phone model. Fitment is crucial due to size or curved edges.

Choose full-glue tempered glass. Avoid edge-glued glass, as these don't provide shock absorption.

Tempered glass should be approximately 0.3 mm thick. This provides a better balance between strength and touch response.

Ensure no bubbles or gaps during installation, as this could directly damage the screen.

Include a good case along with the right tempered glass. Together, they reduce damage in case of a drop.
