Why Redmi 9’s screen breaks more often than others and when it’s time to change it
The screen Xiaomi Redmi 9 is one of the most vulnerable points of the smartphone, despite the manufacturer's stated protection of Gorilla Glass 3.

The main reasons: falls from a height of 1 meter (especially at corners), strong impacts on the body or pressure on the matrix (for example, if you sit on the phone in the back pocket).
How do you know if a screen needs to be replaced, not cosmetically repaired?
- 🔍 Cracks with violation of the integrity of the glass – if the chips touch the inner layers of the display, recovery is impossible.
- 📵 Part of the screen is not working – vertical/horizontal bars, dead zones or “broken” pixels.
- 🔄 The sensor does not respond to touch or is triggered spontaneously (ghost pressing).
- 💡 The backlight flashes or the screen is completely gone, but the phone makes sounds and vibrates.
It's important to distinguish between damage to the matrix (the interior layer that controls the image) and cracks on the protective glass. In the first case, it costs 2-3 times more to repair. It's easy to check this: if you turn on the phone, you can see the image through the cracks, the problem is only in the glass. If the picture is distorted or missing, the matrix is damaged.
