- 🔹 The low-end counterparts are cheap Chinese copies with simplified assembly, often with problems with color reproduction, backlighting or touchscreen, suitable only for temporary use.
For the Redmi Note 4, it is critical to pay attention to the screen version.
- 📱 NTC (with the Xiaomi logo on the plume - the most common option.
- 📱 OFILM (logoless, with different contact locations – less common, but fully compatible.

squash
Step 3: Preliminary testing
- 📱 Connect the battery and turn on the phone without full assembly.
- 📱 Check it out:
⚠️ Note: If the screen does not turn on or flicker after connecting, check: - Density of the plumes (sometimes they "get out" of the connectors). - Integrity of the contacts on the motherboard (can be oxidized). - Screen version compatibility (NTC or OFILM).
1. Go to Settings. → Screen. → Color mode.
2. Select Standard or Saturated mode (depending on your preferences).
3. disable the option Automatic Color Temperature (if any).-->
Step 4: Final assembly
- 🔧 After making sure the screen is working, turn off the battery and carefully stow the plumes.
- 🔧 Twisting all the motherboard screws (do not tug over!).
- 🔧 Stick the new screen evenly pressing it around the perimeter.
- 🔧 Set the back cover and fix it with latches.
💡
The most common assembly error is tug-of-war screws, which can damage the contacts on the motherboard or deform the body, and twist the screws "to the point," but without effort!
5.Typical problems after screen replacement and their solution
Even if you do everything according to the instructions, there may be problems, and let's look at the most common ones and how to fix them.

| The screen flickers. | Poor plume contact or illumination failure | Check the connection density of the display plume |
If the screen is working after the replacement, but there are "dead zones" (unresponsive areas), this may mean:
- 🔍 Damage to the touchscreen plume during installation.

7.Prevention: How to protect the screen Xiaomi Redmi Note 4 from damage
To avoid having to change the screen again, follow the following simple rules:
- 🛡️ Use high-quality glass (e.g. Tempered Glass with a thickness of 0.3 mm). Cheap films do not save from shocks.
- 🛡️ Stick a bumper or case with amplification in the corners - this will reduce the risk of cracks when falling.
- 🛡️ Avoid overheating – do not leave your phone in direct sunlight (this weakens the glue holding the screen).
- 🛡️ Don’t put your phone in your back pocket – it’s the most common cause of falls when sitting down.
- 🛡️ Regularly update the firmware in new versions MIUI Sometimes improve touch processing.
If the screen already has small cracks, but the touchscreen works, you can temporarily "preserve" them with a transparent nail polish. Apply a thin layer on the cracks, this will prevent them from spreading and getting dust.
