Why choose PREMIUM 9H tempered glass?
The screen is the most sensitive and most exposed part of your smartphone. Everyday drops, knocks over keys in your pocket, or sudden drops can quickly cause permanent damage. Our premium tempered glass acts as a bulletproof shield, absorbing the force of impact and preventing damage to the original screen.
It is made of specially treated transparent glass with a thickness of 0.3 mm, which ensures the optimal balance between thinness and robustness. Despite the exceptional protection, the glass does not change the sensitivity of the touch screen, so your user experience will remain completely unchanged.

Complete transparency and smooth operation
Many low-quality screen protectors degrade image quality and reduce brightness. Our PREMIUM 9H tempered glass screen protector for Samsung Galaxy M12 maintains 100% color accuracy and brightness of your screen. Since it is completely transparent, you will forget that it is even installed on your phone. It also does not affect the operation of the sensors or front camera, allowing for smooth photo taking and facial recognition.
An additional advantage is the advanced oleophobic coating. This prevents the accumulation of grease from your fingers, which means you will have to clean the screen much less often. But when cleaning is necessary, just a gentle swipe with a cloth will be enough, without the need for rough rubbing.

Frequently Asked Questions (FAQ)

No. Due to the ultra-thin design (only 0.3 mm) and the use of high-quality genuine tempered glass, the touch screen sensitivity remains completely unchanged. The phone will respond quickly and accurately.
2. What does the 9H hardness rating mean?
The 9H rating represents the material's hardness level on the Mohs scale. This means the glass is extremely resistant to scratches that could be caused by everyday objects such as keys, coins, or even a knife.

Not at all. Our PREMIUM protective glass is completely transparent and does not have the surface haze effect that is common with cheaper protective films. The colors and brightness of your Samsung Galaxy M12 will remain crystal clear.

Same summary

The 9H tempered glass screen protector for Samsung Galaxy M12 is designed to protect the screen from scratches and impacts during normal or slightly more active use of the phone. Due to the precise fit to the model, it provides good coverage and does not interfere with touch operation, which is essential for carefree use. Users looking for very thin and almost invisible protection may notice a slightly larger thickness compared to a classic film. Tempered glass is less suitable for those who only want basic protection against micro-scratches and for whom discretion is key.
