What to do if the vibration on Xiaomi Redmi Note 5 does not work: causes and solutions

The Xiaomi Redmi Note 5 is one of the brand’s most popular budget smartphones, but even it isn’t immune to hardware and software failures. One of the common problems faced by owners of this model is the lack of vibration when calling, notifying or pressing the screen.

In this article, we’ll look at all the possible reasons why the vibration on the Redmi Note 5 (codenamed whyred) may not work, and provide step-by-step instructions for diagnosing and troubleshooting. From simple checks in the settings menu to disassembling the device, you’ll find a solution regardless of your technical background.

Important: some methods require root or unlocked bootloader permission, and if you're not sure about your skills, you'd better go to a service center, but 80 percent of the time, you can fix the problem without tampering with the hardware!

1. Check the basic vibration settings

Before sinning on hardware malfunctions, make sure the vibration is simply not turned off in the settings.The Redmi Note 5 runs on MIUI, where tactile feedback options are scattered across multiple menus.

Open the Settings → Sound and vibration and check:

• 🔔 Vibration when calling – is the slider included in the section “Sound and vibration when ringing".
• 📲 Vibration when touching – option “Vibration when pressed” in the menu “Additional settings".
• 🚨 Do Not Disturb Mode – If activated, vibration can be blocked (check exceptions in Settings) → Don't disturb).

Pay special attention to the sound profile: MIUI has separate settings for Sound, Vibration and No Sound modes, switch between them and check if the vibration is working in each case, and if it appears in one of the modes, the problem is the profile settings.

2. Software failures: reboot and reset settings

If the settings are fine, but there's no vibration, it could be a temporary system failure, and start with the simplest procedure, which is a forced reboot.

1. Press the Power button for 10-15 seconds until the screen goes out.
2. Wait 30 seconds and turn the phone on again.

If that doesn’t work, try resetting the sound and vibration settings to factory:

1. Go to Settings → System and device → Resetting.
2. Select Reset Sound and Vibration settings (not to be confused with a full reset!).
3. Confirm the action and restart the device.

In rare cases, the vibration is lost due to a conflict with the installed applications.

• 🔍 Start the phone in safe mode (clip the power supply) → Click "Switch off power" before the request appears).
• 📱 Check the vibration in safe mode. If it works, uninstall the newly installed apps.

💡

If the vibration is gone after the MIUI update, try to roll back to the previous version via Fastboot or Recovery. Instructions for the Redmi Note 5 are available on the 4PDA forum.

3. Diagnosis of the vibromotor: how to check the hardware

If software methods don't work, the problem may lie in the vibrator or its connection. On the Redmi Note 5, the motor is located near the bottom of the motherboard to check whether it works:

1. Remove the back cover (a plastic shoulder blade and a hair dryer will be needed to soften the glue).
2. Unplug the battery (required!), then find the vibrator motor - a small round element with wires.
3. Check the integrity of the contacts and the plume, and if they're oxidized or damaged, that's the reason.

For direct check of the motor, you can use a multimeter:

• 🔋 Transfer multimeter to resistance check mode (200 ohms).
• 📊 Touch the motor contacts with probes. A proper vibrator will show 8-12 ohm resistance.
• 🚫 If there is no resistance (OL) or close to zero, the engine is defective.

Redmi Note 5 uses a vibrator model JK-4028L-000, its catalog number in the service centers Xiaomi — MB110116. the cost of the original spare part — about 300-500 rubles.

4. Problems with the firmware and core of the system

On the Redmi Note 5, the vibration is controlled at the Android core level (vibrator.ko).If the vibration is lost after firmware or root rights are obtained, the following reasons are possible:

• 🐛 Incompatible firmware - custom ROM (For example, LineageOS may not support the whyred vibrator.
• 🔧 Damaged kernel module - files in /system/lib/modules/ responsible for controlling vibration.
• 📛 Incorrect access rights – after manual interference /dev/vibrator could have gone astray.

To diagnose the problem:

1. Connect the phone to the PC and perform in ADB: adb shell ls -l /dev/vibrator If the file is missing or the rights are different from crw-rw----, need to be reflashed.
2. Check the kernel logs for errors: adb shell dmesg | grep vibrator Errors of the form vibrator_probe: failed to request PWM point to a hardware problem.

If you are using custom firmware, try:

• 🔄 Back on the stock. MIUI via Fastboot.
• 🔧 Reflash the kernel (e.g. FrancoKernel for whyred).
• 📲 Install Vibration Tuner from Play Market to manually adjust intensity.

5. Effect of moisture and physical damage

The Redmi Note 5 does not have official water protection (IP-certification), so even a small ingress of moisture can cause corrosion of the contacts of the vibrator motor.

• 💧 Vibration disappeared after contact with the liquid (even steam in the bathroom).
• 🔋 The phone is poorly charged or spontaneously rebooted.
• 📱 Artifacts appear on the screen or the backlight flickers.

If you suspect moisture intrusion:

1. Turn off your phone immediately and remove the battery (if possible).
2. Place the device in dry rice or silica gel for 24 to 48 hours.
3. After drying, check the vibration. If it does not appear, it requires disassembly and cleaning with alcohol.

Physical injuries (blows, falls) often result in the disconnection of the plume of the vibrator or cracks in the board.

• 🔧 Motor fastening - it must be tightly fixed by screws.
• 📡 Soldered contacts on board (lamp required) lanes detached are common cause.

⚠️ Warning: If the board shows traces of oxidation (green plaque), do not try to clean them yourself! improper cleaning can damage the tracks.

Alternative solutions and interim measures

If repairs are delayed and vibration is critical (for example, for an alarm clock), workarounds can be used:

For the Redmi Note 5 with unlocked bootloader, there is a radical method - firmware alternative core with support for enhanced vibration.

• 🔧 FrancoKernel – allows you to adjust the vibration intensity through the application.
• 📊 Perseus Kernel – Optimized for Whyred, fixes bugs with vibrator motor.

Before you install the kernel, make sure to backup through TWRP!

💡

If the vibration is gone after the phone falls, there is a 90% chance that the engine or plume will be mechanically damaged, in which case only physical repairs will return functionality.

7. When to contact the service center

If none of these methods helped, most likely, a hardware malfunction.

• 🔧 Vibromotor does not show signs of life (no resistance when checking multimeter).
• 📱 On the board you can see damaged tracks or chips.
• 🔋 Vibration works, but the phone overheats or discharges quickly (may indicate a short circuit).

The cost of repairs in official service centers Xiaomi:

Before the service visit:

1. Make a backup of the data (in case of resetting).
2. Check whether the masters use original spare parts (for whyred this is critical).
3. Check reviews about the service - some "masters" replace the vibromotor with cheap analogues that fail in a month.

⚠️ Note: Unofficial services often offer "enhanced" vibration by installing a motor from other models (e.g., the Redmi Note 7!
