How to Fix a Phone That Won't Vibrate

Published 2026-10-16 · Marion Phone Repair

Your phone does not vibrate for incoming calls, text notifications, or haptic feedback when you type. Or it vibrates weakly, makes a buzzing sound instead of a clean vibration, or vibrates constantly without stopping. The vibration motor (also called the haptic engine or taptic engine on iPhones) is a small mechanical component that can fail from wear, drops, or water damage.

Check settings first

Before assuming the vibration motor is broken, verify that vibration is enabled. There are multiple settings that control vibration, and any one of them being off disables it:

iPhone vibration settings

Ring/Silent switch: The physical switch on the left side of the iPhone. When set to silent (orange visible), the phone should vibrate for calls and notifications instead of ringing. If vibration does not work in silent mode, check the settings below
Settings, Sounds and Haptics: Make sure Vibrate on Ring and Vibrate on Silent are both enabled. If both are off, the phone will not vibrate in any mode
Settings, Sounds and Haptics, System Haptics: This controls haptic feedback for keyboard taps, UI interactions, and Face ID. If this is off, you lose haptic feedback for everything except calls and notifications
Focus modes (Do Not Disturb, Sleep, etc.): Active Focus modes can silence vibrations. Check Settings, Focus, and see if a Focus mode is active

Android vibration settings

Volume buttons: Press the volume button to see the volume slider, then tap the icon to cycle through Ring, Vibrate, and Silent modes. Make sure it is set to Vibrate or Ring with vibration
Settings, Sounds and Vibration: Check that Vibrate While Ringing (or Vibrate on Ring) is enabled. Also check vibration intensity — some phones have a slider for vibration strength, and it may be set to minimum
Settings, Sounds and Vibration, Vibration Intensity: On Samsung phones, this has separate sliders for Calls, Notifications, and Touch Interaction (haptic feedback). Make sure none are set to zero
Do Not Disturb: Check if DND is active — it can suppress vibration depending on its configuration
Per-app notification settings: Individual apps can have vibration disabled. Settings, Apps, select the app, Notifications, and check if vibration is enabled for that app's notification channels

Software fixes

Restart the phone

The vibration motor is controlled by a software driver. If the driver crashes or hangs, the motor stops responding to vibration commands. A full restart (power off, wait 10 seconds, power on) resets the driver. After restarting, test vibration by toggling the Ring/Silent switch (iPhone) or using the vibration test in Settings (some Android phones have a vibration test in Sounds and Vibration).

Test with different scenarios

Determine if the motor is completely dead or only not working in certain contexts:

Set an alarm and let it fire — does it vibrate?
Call your phone from another phone with vibrate enabled — does it vibrate for the call?
Type on the keyboard with haptic feedback enabled — do you feel the taps?
On iPhone, try 3D Touch or long-press on an app icon — do you feel the haptic response?

If vibration works in some scenarios but not others, it is a software or settings issue, not hardware. If it works for nothing at all, the motor may have failed.

Update the operating system

Vibration motor driver bugs can cause the motor to stop working or behave erratically. Install any available OS update, as it may include a fix.

Reset all settings

If vibration stopped working and you cannot identify which setting changed:

iPhone: Settings, General, Transfer or Reset iPhone, Reset, Reset All Settings. This resets all settings (including vibration, sounds, display, and network) to defaults without deleting your data or apps
Android: Settings, General Management (or System), Reset, Reset All Settings

Hardware causes

How vibration motors work

Phones use one of two types of vibration motors:

Eccentric rotating mass (ERM): A small motor with an off-center weight that spins to create vibration. Common in older and budget phones. Produces a buzzy, imprecise vibration
Linear resonant actuator (LRA) / Taptic Engine: A voice-coil actuator that moves a mass back and forth in a straight line. Used in modern iPhones, Samsung flagships, and most mid-range to high-end phones. Produces sharp, precise haptic feedback that can simulate different textures and patterns

Signs of motor failure

No vibration at all: The motor has failed completely or its connection to the logic board is broken. This is the most common failure mode after a drop
Weak vibration: The motor is partially failing — on ERM motors, the bearings may be worn. On LRA motors, the spring or voice coil may be weakened. Vibration intensity decreases gradually over time
Rattling or grinding: On ERM motors, damaged bearings produce a grinding sound instead of smooth vibration. On LRA motors, a loose mass or damaged spring produces a rattling or clicking sound
Constant vibration: If the phone vibrates continuously without stopping, the motor driver circuit may be stuck on. A restart usually fixes this — if it does not, the driver IC or its connection may be damaged
Vibration after a drop: A drop can dislodge the motor from its mounting or disconnect its flex cable. The motor itself may be fine but the connection is broken

Water damage

Vibration motors have moving mechanical parts that are vulnerable to water damage. Corrosion on the motor contacts or coil causes the motor to weaken and eventually fail. If your phone was exposed to water and vibration weakened or stopped afterward, water damage to the motor is likely.

Vibration motor replacement

The vibration motor is a small, inexpensive component in most phones. The motor itself typically costs only a few dollars as a part. The labor to access it varies by phone model — in some phones the motor is easily accessible near the bottom of the phone next to the charging port, while in others it requires removing the screen or battery to reach. Replacement is typically quick once the phone is open.

On iPhones, the Taptic Engine is a larger component that is more integral to the phone's operation (it also provides the haptic feedback for the home button on iPhone 7/8 and the side button on newer models). A failed Taptic Engine on an iPhone without a physical home button can make the phone feel unresponsive because the button relies on haptic feedback to feel like it clicks.

Vibration motor repair in Marion

If your phone's vibration is not working, weak, or making unusual sounds, Marion Phone Repair can test the motor and its connection, determine if it needs cleaning, reconnecting, or replacing, and install a new vibration motor to restore haptic feedback and notification vibration.
