Replacement of the display on Xiaomi Redmi Note 4: a complete guide with photos and nuances

Introduction: Should I change the screen myself?

A broken screen on the Xiaomi Redmi Note 4 is one of the most common problems after a fall or impact. The service center will charge from 3,000 to 6,000 rubles (depending on the region and type of module), but with the tools and patience, you can do the procedure yourself, the main thing is to understand that replacing the screen on this model requires accuracy: there is a fragile touchscreen plume, easily damaged lighting and adhesive tape that you have to warm up.

This guide will be suitable for all Redmi Note 4 versions (including Redmi Note). 4X We'll figure out which display to choose (original or analog), what tools you'll need, and we'll detail each step, from disassembling the case to testing a new screen. If you've never repaired a smartphone, be prepared for the process to take 1.5-2 hours.

Before you start, assess the scale of damage: if the screen is only cracked, but the sensor works, just replace the glass (cheaper by 30-50%). If the image is missing or the touchscreen does not respond, you will have to change the entire display module. In any case, before dismantling, be sure to back up the data: even with careful repairs, there is a risk of damaging the fee.

Which screen to choose for replacement?

There are three types of displays available on the market for the Redmi Note 4:

• 🔹 Original (OEM) — removed from donor devices, guarantees 100% compatibility, but is expensive (from 4,500 rubles.
• 🔹 High quality copy (A)+) — It is produced in the same factories as the originals, but with minor deviations (for example, slightly less bright backlight.
• 🔹 Budget analogue (A- or B) is cheap (1500-2,000 rubles), but often has problems with color reproduction, viewing angle or touchscreen sensitivity.

When buying, pay attention to:

• 📌 Type of connector: Redmi Note 4 is used 30-pin connector (not to be confused with 20-pin older models).
• 📌 Availability of frames: some modules are sold with a glued frame, others - without it (you will have to glue from the old screen).
• 📌 Compact: ideally, the set should have adhesive tapes for fixing the plume and backlight.

Required tools and materials

To replace the screen with Xiaomi Redmi Note 4, you will need:

We further recommend:

• 🔧 Antistatic bracelet – protects the board from static electricity (especially important in dry climates).
• 🔧 Lupe or magnifying glass - will help when working with small connectors.
• 🔧 Insulation or paint tape - for marking plumes and screws.

⚠️ Warning: Do not use metal mediators or knives - they will damage the plumes! Also avoid overheating the screen with a hairdryer: if the temperature exceeds 90°C, the polarization film may detach and the display will become cloudy.

Step-by-step instructions: disassembling the phone

Before starting work, turn off the phone completely and wait until it cools down (if it has been used extensively before), it is more convenient to disassemble on a table with a soft substrate (for example, on a napkin) so as not to scratch the body.

Step 1: Removing the back cover

1 Unscrew the two screws at the bottom of the phone (near the Micro-USB connector).

2. Gently apply the lid to the plastic mediator starting at the bottom corner. Move around the perimeter, gradually separating the latches. Don't force -- if the lid doesn't respond, check if all screws are unscrewed.

3. Take the lid off and put it aside, and underneath it you'll see the battery, the motherboard, and the camera.

Step 2: Battery disconnection

1 Unscrew 4 screws that fix the metal plate above the battery.

2. Gently put the battery connector in the plastic mediator and disconnect it. Don't pull the wires -- just the connector itself!

3. If the battery is swelling, don't try to remove it by force, it's dangerous!

Step 3: Disabling the display plumes

1. Unscrew the screws that hold the metal plate above the screen plumes (it is located at the top of the board).

2. With a plastic mediator, gently tuck the display connectors (wide) and the touch screen (narrow). These are fixed with latches - pull them up to release the plumes.

3. Separate the plumes and fix them with tape to the body so that they do not interfere.

⚠️ Attention: The touchscreen plume on the Redmi Note 4 is extremely fragile! If it breaks, you'll have to change the entire display module again. Don't bend it at right angles.

Removing the old screen and preparing to install a new one

This is the most important step. The main task is to carefully separate the display from the body without damaging the plumes and backlights.

Step 1: Warming up the glue

1. Turn the dryer on to the minimum power and warm up the edges of the screen around the perimeter for 2-3 minutes. Keep the dryer at a distance of 5-7 cm, so as not to overheat the display.

2. Check the temperature with your hand -- the screen should be warm, but not hot. If you use a thermo-air station, set the temperature to 70.°C.

Step 2: Display separation

1. glue the suction cup to the bottom of the screen (where the Home button is).

2. Gently pull the suction cup up while putting the screen up with a plastic mediator. Start at one corner and move gradually around the perimeter.

3 If the screen doesn't respond, warm up the problem area again. Don't use metal tools, they'll scratch the glass.

Step 3: Removal of glue residues

1. Once the screen is removed, remove the glue residue from the frame with isopropyl alcohol or acetone. Be careful - do not hit the liquid on the board!

2. Check if there are any glass fragments left on the frame. If so, remove them with tweezers.

3.If the new screen goes without duct tape, apply a thin layer of glue B-7000 perimeter.

💡

If the screen is too tight, try using a thread (like a guitar string) and swipe it under the display and saw the glue back and forth, like in the clip from the sharp cakes.

Installation of a new screen and assembly of the phone

Now we're going to reverse assemble, and it's important to take your time and check every step.

Step 1: Connecting the plumes

1. Carefully place the new screen on the body, combining screw holes and connectors.

2. Reverse the plumes: first the touchscreen (narrow), then the display (wide). Make sure they sit down to the end, you can hear a slight click.

3. Close the plumes with a metal plate and twist the screws (do not pull!).

Step 2: Screen fixation

1. Make sure the display is flat in the grooves of the case. If there are gaps, correct it carefully.

2. Press the screen around the perimeter to make the glue stick. Use a heavy book or special press (if any).

3.Let the glue dry for 10-15 minutes before further assembly.

Step 3: Reverse Assembly

1. Connect the battery and fix it with a plate with screws.

2. Install the back cover starting at the top edge. Make sure all latches are in place.

3. Twirl two screws in the lower part of the body.

💡

After assembly, DO NOT turn the phone on right away! First, plug it into charging for 10-15 minutes, which will help avoid power surges when you first turn on.

Testing and calibration of the new screen

After assembly, it is necessary to check the operability of the display and touch screen.

Touchscreen check

1. Pass the sensor test using the Touch Screen Test app (available on Google Play).
