How to straighten the bent screen Xiaomi at home: 5 proven ways

The screen of Xiaomi smartphone is one of the most vulnerable parts of the device. Even a slight mechanical impact (fall, pressure in the pocket or bag) can lead to deformation of the display: waves on the surface, “bubbles” under the glass or curvature of the matrix. The service center will charge from 3,000 to 15,000 rubles depending on the model, but in 60% of cases the problem can be solved by yourself – if you act carefully and follow proven methods.

In this article, we will analyze 5 working ways to straighten the screen for Xiaomi Redmi smartphones, POCO and Mi (including models with AMOLED- and LCD-You'll learn what tools you'll need, how to avoid damage to the matrix, and when to take no risks and consult with experts. All methods have been tested on real devices, from the budget Redmi. 9A The flagship Xiaomi 13 Ultra.

⚠️ Warning: Not all screen deformities are home repairable. If cracks, black spots or vertical stripes appear after a fall, this means damage to the matrix or plume - in such cases, straightening is useless, you will need to replace the module.

1. Diagnosis: What type of strain is your screen having?

Before you start repairing, determine the nature of the damage, depending on the choice of method and the chances of success:

• 🔹 The waves on the glass -- the surface of the screen floats when you press it, but the image doesn't get distorted.
• 🔹 «Bubbles under glass are visible air pockets on the edges of the display, caused by moisture or dust under the glue.
• 🔹 Matrix curvature - the image is distorted (for example, straight lines become wavy). AMOLED-slack-screen.
• 🔹 Local bloating — the screen area bulges outwards, often accompanied by flickering or artifacts.

The safest for self-repair are waves on glass and small bubbles, and 80 percent of the time, curvature or bloating requires professional intervention.

Method 1: Heating and uniform pressure (for waves on glass)

This is a good way to eliminate small waves caused by detachment of the adhesive layer, and the principle of operation is that heating softens the glue, and the pressure helps the glass to stick back to the sensor.

What you need:

• 🔥 Hair dryer (construction or household with temperature control)
• 📏 Flat heavy object (for example, a stack of books weighing 1-2 kg)
• 🧻 Soft tissue (microfibra)
• 📱 Protective film or scotch (for fixation)

Step-by-step:

1. Turn off the phone and take off the case.
2. Heat the screen with a hair dryer at a distance of 15-20 cm, setting a temperature of 50-60°C (not higher!) Move the hair dryer in circular motions for 2-3 minutes.
3. Put the phone on a flat surface (screen up), cover with a soft cloth and place the load on top.
4. Leave it for 12-24 hours. Check the result in a day.

⚠️ Warning: Do not use this method if there are cracks on the screen! Heating can cause damage to spread and the display to fail completely. Also avoid overheating - temperatures above 60°C will damage the matrix.

Efficiency of the method: ~70% shallow wave. If the first attempt is not satisfactory, repeat the procedure, increasing the load exposure time to 48 hours.

Method 2: Vacuum bag (for bubbles under glass)

If there are air bubbles under the glass, it's usually caused by moisture or dust under the adhesive layer, and the vacuum method helps to pull out the air and restore the tightness of the layers.

Materials required:

• 🛍️ Vacuum pack for food (or sealed zip package)
• 🧹 Blow-out vacuum cleaner
• 🧴 Alcohol wipes (for degreasing)
• 📦 Cardboard or foam (for depreciation)

Algorithm of action:

1. Treat the screen with an alcohol napkin to remove fat and dirt.
2. Place the phone in a vacuum bag, pre-plugged cardboard (to avoid pressuring the buttons).
3. Remove air from the package with a vacuum cleaner (in the blowing mode, direct the flow into the hole of the package).
4. Close the package tightly and leave it for 6-8 hours.
5. Take out your phone and check the results. Repeat the procedure if necessary.

This method is particularly effective for models with LCD-screens (e.g. Redmi Note 10 or POCO X3). For AMOLED-displays (Xiaomi) 12T, Mi 11) vacuum method is less reliable due to the more fragile matrix structure.

Method 3: Use of specialized adhesive (to detach the sensor)

If the screen is not only bent, but also does not respond well to touch, the problem may lie in the detachment of the touch layer, in which case the glue of the screen using special glue, for example, will help, B-7000 or LOCA.

Important: This method requires care and is only suitable for users with experience in disassembling equipment. Errors can lead to a complete loss of performance of the display.

Tools:

• 🔧 Plastic mediators (for disassembly)
• 🧴 Clay. B-7000 or LOCA (2-3 ml)
• 🔥 Dryer or infrared lamp
• 🧤 Gloves and mask (glue is toxic!)

The gluing process:

1. Carefully apply the screen to the plastic mediator, starting from the corners. Do not insert the tool deeper than 2 mm, so as not to damage the plumes!
2. Apply a thin layer of glue B-7000 around the screen (avoid the center where the matrix is located).
3. Press the screen back, removing excess glue with a napkin.
4. Warm up the display with a hairdryer (40–50)°C) for 5 minutes for polymerization of adhesive.
5. Place the phone under load for 12 hours.

⚠️ Attention: Clay LOCA It requires a UV lamp to solidify. It doesn't stick to the screen. AMOLED-Use the displays only B-7000 — LOCA It can damage organic LEDs.

💡

Before applying the glue, check the integrity of the display plumes. If you see tears or traces of oxidation during disassembly, further repair is useless - you will need to replace the screen.

Method 4: Local pressure (for bloating)

If the screen is swollen in one place (for example, after falling into a corner), you can try to push the defect back, which is risky, but sometimes saves you from completely replacing the display.

What do you need?

• 🔨 Dumb object with flat end (for example, wooden spatula)
• 🧻 Soft fabric (for depreciation)
• 📏 Linear or metal plate (for uniform distribution of force)

Implementation technique:

1. Place the phone with the screen up on a flat surface.
2. Cover the swollen area with a cloth.
3. Carefully press the defect through the fabric using a ruler to distribute the force.
4. Hold the pressure for 10-15 seconds, then check the result.

⚠️ Critical: This method is only suitable for small bloating (up to 5 mm in diameter).If the defect is larger or after pressing colored spots appear, immediately stop and contact the service - this is a sign of damage to the matrix.

💡

Local pressure is a last resort, and if the bloating hasn't decreased after the first attempt, repeated manipulations will only make the problem worse.

Method 5: Software calibration (for image distortion)

Sometimes, the deformation of the screen leads to software failures: wrong color reproduction, flickering or distortion of the touch screen, in which case calibration of the display through the engineering menu helps.

Instructions for Xiaomi:

1. Open the phone app and enter the combination: ##3644633###
2. In the engineering menu, select Touch Screen Test.
3. Take the touch test. If the screen doesn't respond correctly, choose Calibration.
4. Follow the instructions on the screen (usually click on the dots that appear).
5. Reboot the phone.

This method won't eliminate physical strain, but it can compensate for software artifacts caused by shifting screen layers. MIUI 12 and newer.

7 When is self-repair not possible?

Not all screen defects can be fixed at home. Contact Xiaomi Service Center if:

• 🚫 There are cracks or chips on the screen (even small ones).
• 🚫 Image flickering or disappearing when pressed.
• 🚫 The display does not respond fully or partially to touch.
• 🚫 Under the glass, black spots or stains are visible (a sign of damage to the matrix).
• 🚫 After a fall, the phone does not turn on or overheats.

The cost of replacing the screen in official Xiaomi services (as of 2026):

⚠️ Important: In informal services, the price may be lower, but there is a risk of installing an unoriginal display, which will lead to deterioration of color reproduction, problems with touching or rapid wear of the screen.
