Step-by-step instructions: how to disassemble Redmi Note 9 and replace the screen

The process of replacing the display with Redmi Note 9 takes about 1-2 hours if you have experience. If this is your first time doing this, be patient. Follow the instructions strictly in order to avoid damaging cables or other components.

Step 1: Removing the back cover

1. Turn off your phone and remove the SIM card tray.

2. Heat the edges of the back cover with a hairdryer (do not direct the air flow towards the camera or battery!).

3. Gently pry off the lid with a plastic spatula, starting at the bottom corner. Use a suction cup for convenience.

4. Set the cover aside - under it you will see the battery and motherboard.

Step 2: Disconnecting the Battery

⚠️ Attention: Never operate your phone while the battery is connected! This may cause a short circuit and damage the motherboard.

1. Unscrew the screws securing the metal plate above the battery.

2. Disconnect the battery cable using a plastic spudger (do not pull the wires!).

3. You can check the disconnection with a multimeter (the voltage between the contacts should be 0 V).

Step 3: Removing the Old Display

1. Heat the front of the phone (especially around the edges) with a hairdryer to soften the adhesive.

2. Pry off the screen with a plastic spatula, starting from the bottom (where the charging connector is).

3. Carefully separate the display from the frame, being careful not to tear the sensor and backlight cables.

4. Disconnect all cables from the motherboard (usually there are 3 of them: display, touchscreen, backlight).

Step 4: Installing a New Display

1. Transfer all additional details from the old one (camera, speaker, notification LED) to the new screen.

2. Connect the cables to the motherboard in reverse order.

3. Apply a thin layer of glue B-7000 around the perimeter of the frame and gently press the new display.

4. Make sure that the screen sits flat, without gaps.

Step 5: Assembling the Phone

1. Connect the battery and check the functionality of the new screen (sensor, backlight, color rendering).

2. Reinstall the back cover, having first cleared it of old glue.

3. Tighten all screws and check the phone for any abnormal noise (for example, loose parts).

Common mistakes when replacing a display and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns. Here are the most common problems and ways to prevent them:

• 🔌 Damage to cables - the most common consequence of careless work. Always use plastic spatulas and do not pull on wires.
• 🔥 Overheating of components - the hair dryer should be at minimum power (up to 80°C). Keep it 5–10 cm away from the phone.
• 🔋 Short circuit - Never touch the motherboard contacts with your bare hands. Wear an antistatic wrist strap or gloves.
• 📱 Uneven screen adhesion - If the adhesive is applied in a thick layer, gaps or spots may appear on the display.
• 🔍 Dust getting under the screen - Work in a clean area and use a vacuum cleaner to remove small particles.

⚠️ Attention: If after replacement the screen works, but the sensor does not respond to touches, most likely the problem is in the touchscreen cable. Try reconnecting it or replacing the cable separately (costs about 500–1,000 ₽).

Another common problem is incorrect color rendering after installing the analogue. If colors look too cool or warm, check your display settings in the menu Settings → Display → Color scheme. Sometimes a factory reset helps.

What should I do if the screen flickers or goes blank after replacement?

This may be caused by poor contact of the backlight cable or damage to the inverter. Try:

1. Reconnect the backlight cable.

2. Check the integrity of the contacts on the motherboard (clean with alcohol if necessary).

3. If the problem persists, the display module itself may be faulty.

Where to buy an original display for Redmi Note 9

Buying high-quality spare parts is the key to long-term operation of the phone after repair. Here are trusted sources where you can buy an original or similar quality screen:

• 🛒 Official dealers Xiaomi — guaranteed original parts, but the price is higher than the market price.
• 🌍 AliExpress - look for sellers with a rating above 98% and reviews of compatibility with Redmi Note 9 (models M2003J15SC/SS).
• 🏬 Local parts stores - for example, "Mobilist" or "RepairTechno". Ask for a quality certificate.
• 🔄 Forums and groups on Telegram — they often sell used originals from disassembly (for example, 4PDA or Xiaomi Russia).
• 🛠️ Workshops selling spare parts — some services sell displays separately from the replacement service.

When purchasing, pay attention to:

• 📋 Phone model - screen for Redmi Note 9 not suitable for Note 9 Pro or Note 9S!
• 🔍 Availability of all loops — the kit must include a display, touchscreen and backlight.
• 📦 Packaging — original spare parts usually come in branded boxes with a hologram.

⚠️ Attention: Be careful with sellers who offer “original” displays at the same price (below 4,000 ₽). There is a high risk of running into a fake.

Is it worth changing the screen yourself or is it better to contact a service?

The decision depends on your experience, availability of tools and willingness to take risks. Let's compare the pros and cons of each option:

Criterion	Self-replacement	Contacting service
Cost	✅ Cheaper (only the price of spare parts)	❌ More expensive (labor + spare parts)
Time	❌ 1–3 hours (if no experience)	✅ 30–60 minutes
Warranty	❌ No (if you break something, the fault is on you)	✅ Yes (from 1 to 12 months)
Quality	⚠️ Risk of errors (bad glue, crooked screen)	✅ Professional installation
Tools	❌ Need to buy/rent	✅ The master has everything

If you have never disassembled smartphones, it is better to contact the service. However, if you have experience repairing electronics and the necessary tools, doing the replacement yourself can save you up to 50% of the cost.

⚠️ Attention: If the phone is under warranty, repairing it yourself will lead to its loss! In this case, please contact only official service centers Xiaomi.

This is a typical problem when installing a non-original display. Possible reasons:
