Why Redmi 7A Screens Break More Than Others and When It’s Time to Change
The screen Xiaomi Redmi 7A is one of the most vulnerable points of this budget smartphone. Despite the modest price of the device (about 6-8 thousand rubles at the time of release in 2019), the repair of the display costs owners 30-70% of the cost of a new phone. Why is this happening? It is in the design features of the model: thin glass Gorilla Glass 3 (not 5 or 6, as flagships), the lack of oleophobic coating and weak protection from blows to the sides. Even a fall from a height of 50 cm to asphalt in 60% of cases leads to cracks or complete failure of the sensor.
But not every crack needs to be replaced, and here are some clear signs that the screen is not going to be saved and that the module needs to be completely replaced:
- 🔴 «A web of “cracks” with divergent rays from the point of impact – even if the sensor works, microcracks will spread.
- 🖥️ Black stripes or “broken” pixels are a sign of damage to the matrix, not just the glass.
- 👆 The sensor does not respond to touch or fires spontaneously (ghost touch).
- 🔦 Backlight flashes or is missing, although the phone is turned on (load sounds are heard).
If the screen is only 1-2 cracks without branches, and the sensor works stably, you can do with the replacement of glass (cost - from 1,200 rubles) or gluing the protective film (300-500 rubles). But remember: Redmi 7A does not support the official replacement of glass separately from the matrix - this is a half-measure that will prolong the life of the display for 3-6 months.
How much does it cost to replace the screen in 2026: a comparison of prices in services and private

|---|---|---|---|---|
| Original (OEM) | 5 500 — 7 200 | Official Xiaomi services, large networks (Svyaznoy, M.Video) | 6-12 months warranty, perfect color reproduction, no sensor issues | Long wait (7-14 days), high price |
| Copy (A+) | 2 800 — 4 000 | Unofficial services, private masters | Price 2 times lower than the original, replacement in 1-2 hours | Sensor can “glut”, color reproduction is worse by 10-15% |
| Rebuilt | 2 000 — 3 500 | Small workshops, Avito | The cheapest option | 30% marriage risk, no guarantee, artifacts on the matrix are possible |
| Self-sustaining replacement | 1,500 to 2,500 (part) | AliExpress, Beru, local parts stores | Minimum costs, experience of repair | It is difficult to find a high-quality copy, the risk of damaging the plumes |
⚠️ Xiaomi’s official services often refuse to repair Redmi 7A The alternative is authorized partners, such as iService or TopService, which use original on-screen disassembly modules.
Prices in the regions can vary by ±20%, for example, in Yekaterinburg, replacing a copy of the screen will cost 3200 rubles, and in Krasnodar - 3 800.

⚠️ Warning: If the screen flashes or doesn't turn on after replacement, check:
- The density of the plumes fit (sometimes light pressing helps).
- Polarity of battery connection (tangled contacts lead to short circuit!).
- Integrity of flexible cables (if damaged, soldering is needed).
