Xiaomi Redmi Note 7 is still one of the most popular budget smartphones, despite the release of newer models. Its reliability and price-quality ratio attract users, but even such a device is not immune to falls and cracks on the screen. If you break the glass on your Redmi Note 7, the first thing that worries is the cost of repair. In this article, we will analyze all the options for replacing: from official services to self-repair, compare prices, timing and risks.

What exactly broke: diagnosis of damage
Before you search for a workshop or order parts, you need to know exactly what part of the screen is damaged, and the technology and the cost of the repair depends on it.
- 🔍 Only the protective glass is cracks or chips on the outer layer, but the image and sensor work fine.
- 📱 Touch module – the screen is whole but does not respond to touch (or reacts incorrectly) Requires a replacement of the sensor or the entire module.
- 🖥️ Matrix (display) - there are broken pixels, stripes, dashes or images on the screen completely missing.
- 💥 Full failure - screen doesn't turn on, no backlight, smartphone doesn't respond to charging.Maybe motherboard issues.
To test the performance of the matrix, hold the phone to bright light at an angle — if the screen is off and you see the contours of the images (images, text), then the matrix is intact, and only the glass or backlight is damaged. If the screen is completely black and does not respond to light, then the problem is most likely more serious.
⚠️ Warning: If the phone overheats, discharges quickly or does not turn on after a fall, do not rush to change the glass. First check the integrity of the battery and board at the service center.
For accurate diagnosis at home, you can use Xiaomi test modes:
- Enter the code ##6484## in the Phone app.
- Select the Manual Test item → Touch Panel Test.
- Check if the screen responds to touches throughout the area.

- ⏱️ Speed – no need to wait in line in the workshop.
- 🔧 Experience is a useful skill for future repairs.
Cons and risks:
- ⚠️ Damage to plumes - with careless screen removal, flexible cables can be broken.
- 🔥 Overheating of components - without thermal control, you can damage the motherboard.
- 🚫 Loss of leakage – after repair, the phone may lose protection from moisture (IP-certificate).

Frequent mistakes when replacing glass and how to avoid them
Even experienced craftsmen sometimes make mistakes when repairing the Redmi Note 7, and here are the most common problems and ways to prevent them:
- 🔥 Overheating of components - if you heat the screen with a hair dryer for too long, you can damage the battery or chips. Optimal temperature: 80-90°C no longer than 10 minutes.
- 🧲 Magnetic interference - do not use magnetic screwdrivers near speakers or the camera.
- 💧 Moisture intake - after changing the glass, check the tightness of the phone. If there are gaps, moisture can penetrate and cause corrosion.
- 📶 Poor antenna contact – make sure all plumes (especially Wi-Fi and other devices) are assembled 4G) They're tightly connected, otherwise the network signal will deteriorate.
- 🎨 Uneven backlighting -- if a new screen has yellowness or dark spots, it's a matrix marriage.
One of the most insidious mistakes is that the battery plume is damaged, and on the Redmi Note 7, it's very thin, and it's located next to the display module, and if you hit it, the phone will stop turning on.
- Turn off the battery first.
- Do not pull the plume - just gently pull the side.
- Use plastic tools (mediators, shoulder blades).
Another common problem is that the sensor is broken after replacement, and this can be caused by:
- Incompatibility of the module (for example, the sensor from the Redmi Note 7 Pro was installed).
- Damage to the plume during disassembly.
- No contact in the connector (need to reconnect).
- Software failure (helps reset settings).
