Replacement of glass on Xiaomi Redmi Note 4: prices 2026, where cheaper and how not to run into fraud

Cracked glass on Xiaomi Redmi Note 4 — This is a problem that almost every smartphone owner faces. 2-3 Even the most careful users are not immune to falls, bumps or factory failures of the display module, but if chipping on the edges can still be tolerated, deep cracks not only damage the appearance, but also threaten safety: fragments can injure the fingers, and the damaged glass will eventually begin to “web” spread throughout the screen.

Cost of glass replacement at Redmi Note 4 varying 800 before 3500 But there are a lot of pitfalls, from fakes for the original displays to "masters" who, instead of replacing glass, offer a complete module change at a price of two. 2-3 In this article, we'll look at how much it actually costs to repair, where it's best to do it, and how to distinguish between quality parts and garbage that will last a month.

We will warn you right away: Xiaomi Redmi Note 4 (codename nikel) was released in several versions - with Helio processors X20 (Global version) and Snapdragon 625 (Indian version of Redmi Note) 4X). This is important because the display modules for these versions are not interchangeable! If the master does not specify the model of your device before repairing - this is a reason to be wary.

1.Why the glass on the Redmi Note 4 breaks: Model weaknesses

The Xiaomi Redmi Note 4 design has several vulnerabilities that make glass fail more often than competitors:

🔹 It's a thin, oleophobic coating, and after a year of active use, it wears off, and it's more susceptible to scratching from the sand or keys in your pocket, unlike flagships like the Mi 11, which use hardened glass from Gorilla Glass 5.+, Here is a budget solution - Asahi Dragontrail, which is worse resists blows.

🔹 The flat body shape, the model has virtually no sidebars on the edges of the screen, so when you fall face down, you hit the glass directly, not the aluminum frame.

🔹 The glue is poor quality. Over time, the factory glue loses its elasticity, and the glass begins to "step away" from the touch layer, which manifests as white spots at the edges of the screen or "detachment" when pressed.

🔹 In 2017-2018, there were complaints about defective displays where the glass cracked on its own due to the internal stress of the material.If your Redmi Note 4 was bought during this period and cracks appeared without impact, it could be a warranty case (even years later)!

⚠️ Warning: If cracks on the screen appeared for no apparent reason (the phone did not fall, was not subjected to pressure), check the serial number on the Xiaomi Verify website.

Interesting fact: the version of the Redmi Note 4X (Snapdragon 625) glass breaks less often than the model with Helio X20. This is due to another design of the display module - the "snapdragon" version it is thinner by 0.3 mm, but due to a different load distribution better tolerates shocks.

2.How much does it cost to replace glass: a price comparison in 2026

The cost of repair depends on three factors:

1. Part type (original, OEM, analogue);
2. Repair site (service center, private workshop, independent replacement);
3. Additional work (replacement of glue, cleaning of fragments, checking the sensor).

Below are the current prices for June 2026 (for Moscow and the regions), and note that the capital city costs 20-30% more than in small cities.

Important: the prices are for the spare part only. The work of the master will cost an additional 500-1500 rubles depending on the complexity. For example, replacing only glass (with re-adjustment) costs more than installing the finished module, because it requires more time and special equipment.

3. Official service vs private workshop: where cheaper and more reliable

Choosing between a Xiaomi service center and a garage workshop is always a trade-off between price, speed and quality, and let’s look at the pros and cons of each option.

🔧 Official Xiaomi Service Center:

• ✅ 1 year warranty for work and parts (provided that the phone is not dropped after repair).
• ✅ Use only original or certified OEM-spare parts.
• ✅ Check the phone for hidden defects (for example, damage to the camera plume after a fall).
• ❌ Expensive: replacement of the display module will cost 3200-3800 rubles (including work).
• ❌ Long: if there is no spare part in the warehouse, you will have to wait 1-2 weeks.
• ❌ Not all SCs work with outdated models (for example, in small cities may refuse to use them).

🛠️ Private workshop:

• ✅ Cheaper by 30-50%: the average replacement price is 1500-2200 rubles (with work).
• ✅ Fast: Most repairs are done in 1-2 hours.
• ✅ You can agree on a guarantee (usually 3-6 months).
• ❌ Risk of running into a fake: some masters install cheap analogues under the guise of OEM.
• ❌ There is no check of related malfunctions (for example, it may turn out that after replacement the vibromotor does not work due to a damaged plume).
• ❌ The quality of work depends on the skill of the master (for example, poorly glued glass will begin to go away after a month).

🏠 Self-sustaining replacement:

• ✅ The most budgetary option: spare part + tools will cost 1000-1500 rubles.
• ✅ You can choose a quality part (for example, order a car). OEM-module on AliExpress).
• ❌ High risk of error: without experience, it is easy to damage plumes or sensors.
• ❌ A special tool is required (suction cup, mediator, hair dryer for heating glue).
• ❌ There is no guarantee – if something goes wrong, you will have to carry it to the service.

💡

Before visiting the workshop, take a picture of the cracks on the screen and make a backup of the data. Some craftsmen may say that the phone is not turning on due to a fall (though in fact they just forgot to plug in the plume), and demand a surcharge for “additional repairs”.

🔍 How to Choose a Reliable Workshop:

1. Check the reviews on Yandex.Maps or 2GIS (pay attention to the before/after photo).
2. Ask if you have a job guarantee and a spare part (if not, this is a reason to doubt).
3. Find out what module you will be using (ask to show the package).
4. Look at the workshop: if it is dirty and smells of soldering iron, it is better to leave.

💡

The best option for the ratio of price / quality - a proven workshop with a guarantee of 6+ Official service is only justified if the phone is warranty or you are critically important to the perfect color reproduction of the screen.

4. Can only glass be replaced, not the entire display module?

Yes, it is possible, but not in all cases. The fact is that the Xiaomi Redmi Note 4 has glass glued to the touch layer and the matrix, which can be separated, but the process is time-consuming and requires special equipment.

🔎 When it is important to change only the glass:

• ✅ The sensor works perfectly (no dead zones, freezes).
• ✅ Matrix not damaged (no broken pixels, lighting uniformly).
• ✅ Cracks only on glass, without damaging the inner layers.

🚫 When you need to change the entire module:

• The sensor does not respond to touch or it works spontaneously.
• On the screen appeared colored stripes or broken pixels.
• The lights flash or part of the screen is dim.
• The glass is so badly broken that the fragments damaged the matrix.

💰 Cost of replacing glass only:

If the master agrees to such repairs, be prepared to pay:

• 📱 Glass. + work: 1500-2500 rubles (depending on the quality of the glass).
• 🔧 Additional: Replacement of glue may be required (more) +300-500 rubles).

⚠️ Important: After replacing only the glass, no one will guarantee the sensor, and if the touchscreen stops working in a month, you'll have to change the entire module.

Make sure the sensor is working without any complaints|Check the matrix for broken pixels (you can use the screen test)|Ask the master what glue he will use (better — B-7000 or LOCA)|Ask for a job security (at least 1 month)-->

5. Step-by-step instructions: how to replace glass yourself

If you decide to repair yourself, follow this instruction. Attention: this process requires care and patience. A mistake can lead to a complete breakdown of the phone!

🛒 What's the matter:

• 📱 New glass (or display module) for Xiaomi Redmi Note 4 (check compatibility with your revision!).
• 🔧 Set for repairing smartphones (suction cup, mediators, screwdrivers).
• 🔥 Hair dryer (preferably construction, but suitable and household at maximum capacity).
• 🧴 Clay. B-7000 or LOCA (If you only change the glass).
• 🧻 Lilaless wipes and alcohol for cleaning.

🔧 Step-by-step process:

1. Turn off the phone and remove it. SIM-card.
2. Heat the screen with a hair dryer (temperature) ~60°C) for 2-3 minutes to soften the glue.
3. Put a sucker on the glass and carefully separate it from the body with a mediator.
4. Turn off the display plume (it is under the metal cover that needs to be unscrewed).
5. Clean the frame of the old glue with alcohol and a napkin.
6. Apply a new glue to the frame or back of the glass (if you change only it).
7. Install a new glass/module and press (you can use a heavy book for 10-15 minutes).
8. Connect the plume and collect the phone in reverse order.

🎥 Video Instructions (We recommend you to watch before starting work):

Example: Replacement of the Redmi Note 4 glass on YouTube.

⚠️ Warning: If the phone doesn’t turn on or the screen doesn’t respond after assembly, check:

• Is the display plume connected (sometimes it falls out during assembly).
• Is the flexible board damaged (if so, a replacement module will be required).
• Did the dust get under the glass (this can cause white spots)?

6. Frequent mistakes when replacing glass and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to re-repair, and here are the most common mistakes and how to prevent them:

🔴 Mistake 1: Using the wrong glue

Many people save and take the usual superglue or Moment, but it turns yellow over time and loses its elasticity — B-7000 or LOCA.

🔴 Mistake 2: Overheating of the screen with a hairdryer

If the matrix is overheated (above 70)°C), it can change color or fail altogether. Right: warm for no longer than 3 minutes and keep the hair dryer at a distance of 5-10 cm.

🔴 Error 3: Damage to the display plume

The plume is very fragile, and it's easy to break when you unplug it, which is right: use a plastic mediator, not a metal tool.

🔴 Mistake 4: Getting Dust Under Glass

Even microscopic dust particles will be visible as white dots, right: work in a clean room and use antistatic wipes.

🔴 Error 5: Failure to check the sensor after replacement

Sometimes a new display module has sensor defects that only show up in a few days, right: before paying for work, test all the screen functions (multi-touch, gestures, sensitivity).

🔴 Mistake 6: Savings on parts

Cheap analogues often have poor color reproduction or uneven lighting. Right: if the budget allows, at least take it. OEM-spare.

💡

The most common reason for re-repairing is a poorly cleaned surface before bonding, and even a small motif can cause the glass to detach within a week.

7. Alternative methods: can we do without replacement?

If the cracks are shallow and do not interfere with use, you can try temporary solutions:

🔹 Film or glass with cracks

Special protective films (for example, Brotect AirGlass) can hide small scratches and prevent further cracking.

🔹 Liquid glass

It's applied to the screen and fills in the microcracks, making them less visible, lasts 2-3 months, costs 300-800 rubles.

🔹 Replacement of the case with display

AliExpress sells the case Redmi Note 4 assembled with a display for 2500-3500 rubles. Suitable if in addition to glass damaged and the body. Minus: you have to carry all the internal components (motherboard, camera, etc.), which is risky without experience.

🔹 Software disguise

If cracks are only on the edges, you can turn on black bar modes in the settings (Settings) → Screen. → Screen size. This will hide the damaged areas, but it will reduce the useful area of the display.

⚠️ Warning: All of these methods are just temporary solutions, and if the cracks are deep or the glass is starting to crumble, sooner or later you'll have to make a full repair.
