Replacement of the display on Xiaomi Redmi Note 7: a complete guide with photos and nuances

Xiaomi Redmi Note 7 remains one of the most popular smartphones in the budget segment even years after its release. However, its main drawback is a fragile display that often cracks when falling. If you encounter a broken screen, do not rush to carry the phone into the service: you can replace the module yourself, saving up to 70% of the cost of repair. In this guide, we will analyze the entire process from the selection of parts to the final test, taking into account the typical errors and hidden nuances that even experienced craftsmen keep silent.

It’s important to understand that replacing the display with the Redmi Note 7 is different from the same procedure on new Xiaomi models, using adhesive attachment (not latches like in the Redmi Note 10), and the plumes are connected to the motherboard through fragile connectors. The model also has two versions of the displays, with IPS and AMOLED-You can't replace them without losing functionality. If you've never disassembled a smartphone, be prepared for the process to take 2-3 hours and be patient.

Before proceeding, assess the extent of the damage:

• 🔍 Cracks without illumination – it is enough to replace the glass (cheaper by 40–50%), but the risk of damaging the matrix is high.
• 💡 Black screen with working sound – a problem in the plume or matrix, you need a complete replacement module.
• 🔄 Artifacts (stripes, flickering) - a defect of the graphics chip is possible (a card diagnosis is required).
• 🚫 Sensor does not respond – often to blame departed plume touchscreen (sometimes helps reconnection).

1. Display selection: original vs. analogues

Part quality is responsible for 80% of repair success, and there are three types of displays available on the market for the Redmi Note 7:

Where to buy:

• 🛒 AliExpress is 30% cheaper, but delivery is 3-4 weeks%+ and photo reviews.
• 🏬 Local service centers are more expensive, but you can check the display before buying.
• 🌍 eBay/Amazon — Original parts, but the prices bite + customs.

⚠️ Note: In 2023, cases of selling displays with cross-stitched matrices have increased (for example, instead of using the same system). AMOLED slip-up IPS Before buying, ask the seller for a photo of the serial number on the plume - it should begin with TFT (for IPS) or AM (for AMOLED).

Essential tools and training

To replace the display on the Redmi Note 7, you will need a specialized set, as standard screwdrivers and mediators will not work.

• 🔧 Plastic blades (0.1–0.2 mm) – to separate the display from the body.
• 🔨 Cross screwdriver T3 — rear-cover.
• 🔥 Hair dryer or thermoplatform - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic mat - so as not to lose the screws (there are 12 pieces!).
• 📱 Suction cups - for a careful lifting of the display.
• 🔌 Tweezers - to work with plumes.
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner.
• 🎨 Double-sided tape or glue B-7000 — fixing.

Preparation of the workplace:

1. Turn off the phone and remove it. SIM-map + memory card (they may interfere with the).
2. Discharge the battery to 20-30% – it is safer when working with plumes.
3. Remove the back cover (it is attached to the latches). + 12 screws. Use a hair dryer to soften the glue around the perimeter.
4. Turn off the battery (a plume with the inscription) BATTERY) — This will prevent short circuiting.

⚠️ Warning: Do not use metal blades to separate the display! They will damage the antenna tracks under the frame, which will lead to loss of network or Wi-Fi. Plastic blades must be new - old can have burrs.

3. disassembling the phone and removing the old display

This is the most important stage. The main difficulty is to separate the display from the frame, because Xiaomi uses a very strong glue.

1. Heat the body. Use a dryer at 70-80.°C, evenly warming the edges of the display for 2-3 minutes. Don't overheat! Temperature above 90°C will damage antenna modules.
2. Display compartment. Attach the suction cup to the bottom of the screen (where the charging connector is) and gently pull up, insert the plastic blade into the gap, and slowly guide it around the perimeter, separating the glue.
3. You'll see 3 plumes when you take the display off: 📺 Display (the widest, on top). 👆 Touchscreen (thin, under display). 🔋 Backlights (small, right).

Turn them off with tweezers, pulling on the black tongues (not by the plumes!).

Removal of old glue.

Common mistakes at this stage:

• ❌ Sharp display compartment → Breaking the lighting plume (you will have to buy a new module).
• ❌ Dryer overheating → detachment of antenna tracks or deformation of the frame.
• ❌ Use of a knife instead of a shoulder blade → finger-cut + matrix-damage.

4. Installation of a new display and assembly

Before installing the new module, check:

• 🔍 Presence of protective film on the inside of the display (it must be removed!).
• 🔌 Integrity of plumes (no cracks or breaks).
• 📏 Coincidence of connectors (on some copies, the plumes can be displaced by 1-2 mm).

Procedure:

1. Apply a thin layer of glue B-7000 The perimeter of the phone frame (not on the display!) The alternative is two-way Scotch. 3M 9448A (roll-sold).
2. Carefully put the new display plumes into the connectors and lock them in tongues. Don't push hard, the contacts are fragile!
3. Press the display against the frame, starting at the top (where the front camera is) and make sure it lies flat, without skewing.
4. Secure the display with paint tape at the edges and leave for 10-15 minutes (glue should grab).

Phone assembly:

1. Connect the battery and check the display before final assembly.
2. Set the back cover by snapping it around the perimeter (start with the bottom).
3. Twisting all 12 screws (do not pull!).

💡

If the display flickers or stripes appear after assembly, check the density of the plumes. Often the problem is solved by reconnecting (without glue!).

Testing and calibration

After replacing the display, you need to check all the functions:

• 🎨 Color rendering – compare with another phone (should match the shades).
• 👆 Touchscreen – Test multi-touch (touch with 5 fingers at the same time).
• 🔦 Autobrightness – Cover the light sensor (near the camera) and check the reaction.
• 📶 Network/Wi-Fi — Make sure the antennas are not damaged (sometimes the signal is lost due to improper assembly).

If something is not working properly:

• Artifacts on screen → poor fit of the display plume or matrix defect.
• Touchscreen's not working. → Check the touchscreen plume (it may not be fully inserted).
• Low maximum brightness → typical for budget analogues (solved only by replacing the high-quality display).

To calibrate the touchscreen (if the sensor is "floating"):

1. Go to Settings → About Phone → MIUI version (shap 7 times to activate developer mode).
2. Return to Settings → Additional → For developers → Calibration of the sensor.
3. Follow the instructions on the screen (usually click on the crosses that appear).

💡

If after replacing the display, the phone does not turn on, first check the battery connection, and then the integrity of the power plume (it goes from the on button to the motherboard).

Frequent problems and their solutions

Even with a careful replacement, problems can occur, and here are the most common ways to fix them:

If after the replacement of the display appeared stripes on the edges, it may be due to:

• Incompatibility of the matrix (you have established the IPS instead AMOLED vice versa).
• Damage to the plume of the backlight (often happens with careless disconnection).
• Defect of the new display (return it to the seller under warranty).

⚠️ Warning: If the phone starts to run out quickly after the display is replaced, check if the high performance mode is still on (sometimes it activates automatically after repair). → Battery → Modes and select "Balanced".

7. Cost of repair in the service vs. self-replacement

Prices for the replacement of the display Xiaomi Redmi Note 7 in services (2026):

When to contact the service:

• 🛠️ If you don’t have experience disassembling phones (risk of damaging the fee or plumes).
• ⚡ If after self-replacement there were problems with charging, network or speaker (possibly damaged antenna tracks).
• 🔧 If you need to replace the glass separately from the matrix (this is jewelry work, requiring special equipment).

Advantages of self-repair:

• 💰 Savings of up to 50% of the cost.
• 🕒 No queues and no waiting.
• 🔧 You know exactly what part is installed (in services sometimes put cheap analogues without warning).

💡

If you doubt your abilities, start by buying a used display at the disassembly (costs 800-1 500). ₽). This will allow you to practice without risking spoiling the new module.
