Why does the camera glass on Redmi 9A burst and when exactly you need to change it?
The camera glass on the Xiaomi Redmi 9A is one of the most vulnerable parts of the smartphone. Even a slight fall on asphalt or hitting a hard surface can lead to cracks, chips or complete destruction of the protective glass. Unlike the main screen, which is often protected by hardening, the camera glass is usually thinner and has no additional layers, making it the first candidate for damage when mechanically exposed.
But not always a crack is a reason for an urgent replacement, and if the camera continues to focus normally and the photo is free of artifacts (blurring, glare or dark spots), you can temporarily do without repair, but there are three critical signs in which it is dangerous to delay the replacement:
- π There were glare or rainbow spots in all the photos β this means that the glass fragments hit the lens.
- π΅ The camera stopped focusing or it makes an error: "I failed to connect to the camera".
- π§ Under the glass visible moisture or condensate - this is a threat of corrosion of the internal parts of the module.
Redmi 9A owners often face this problem because of its design: the camera glass protrudes 1-1.5 mm above the body, making it vulnerable even with light impacts. According to service centers, 3 out of 10 repairs of this smartphone are due to damage to the camera glass.
How much does it cost to replace camera glass in service centers (prices 2026)
The cost of replacement depends on three factors: region, type of service (official or unofficial), and quality of parts used. In Moscow and St. Petersburg, prices are 20-30% higher than in the regions, but the quality of work is usually better.

| Official Xiaomi Service (Mi Service) | 1 800β2 500 | 6β12 months | 1-3 days |
| Authorized partner centers | 1 500β2 200 | 3β6 months | 2-5 hours |

What distinguishes the original glass from the analogue: is it worth overpaying?
In the Xiaomi Redmi 9A parts market, there are three types of camera glass: original (OEM), quality, and low-cost counterfeits, the difference between them not only in price, but also in durability, optical properties, and even the impact on photo quality.
| Type of glass | Price (β½) | Pluses | Cons |
|---|---|---|---|
| Original (OEM) | 600β1 200 | Perfect transparency, accurate landing, long service life (3-5 years) | High price, difficult to find in small towns |
| High-quality analogue (Huaqin, Sunwoda) | 300β700 | Good transparency, availability, 6-12 months warranty | Can slightly distort the colors in the photo in bright light |
| Low-cost fake (no-name) | 100β300 | Low price, fast order execution | Yellow over time, scratches, worsens the quality of the photo |
The main difference between the original glass is the anti-reflective coating, which reduces the amount of glare in the photo. In cheap analogues, this coating does not exist, which can cause rainbow spots in pictures against the sun. In addition, the original glass is thinner by 0.1-0.2 mm, which is important for proper focusing.
If you take most of your photos indoors or in cloudy weather, the difference between OEM and good ones is minimal. But if you shoot often outside in bright sunshine, you better not save. Counterfeit glass can start to get cloudy in 3-6 months because of the oxidation of the adhesive layer.

What to do if the camera becomes worse after the replacement
If the camera glass is replaced after repair, but the photos are blurred, with glare or incorrect color reproduction, the problem may be one of four factors:
- Incorrect installation of glass: if it is offset relative to the center of the lens or glued at an angle, the light will be refracted incorrectly. Solution: reglue the glass using a pattern for centering (you can print it from the Internet).
- You get dust or glue on the lens: even microscopic particles can scatter light, so you can take the module apart, clean the lens with alcohol, and glue the glass.
- Low-quality glass: cheap ones often have a greenish or yellowish hue, so you can replace them with the original or the quality one.
- Camera damage: If the glass is overheated or the module is deformed, autofocus may be affected.Solution: diagnostics in the service (the entire module may need to be replaced).
To check what exactly the problem is, take test pictures in different conditions:
- πΈ In bright light: if there are rainbow spots - a problem in the glass or its installation.
- π In the dark with a flash: if the photo is too dark, it may be too thick and block the light.
- π Macrosnip (close distance): if the object is not in focus, the centering of the glass is disturbed or autofocus is damaged.
If you have replaced the glass yourself and are experiencing a deterioration in quality, try resetting the camera to factory settings: go to Settings β Apps β Camera β Storage β Clear data. Sometimes this helps to return the normal operation of autofocus.
