How to Fix a Phone Vibration Motor That Is Not Working

Published 2026-10-16 · Marion Phone Repair

Your phone does not vibrate. You set it to vibrate mode and it stays completely silent with no tactile feedback. Notifications arrive without vibration, calls do not vibrate, and haptic feedback from typing or gestures does not work. Or the vibration motor is weak — it used to produce a strong buzz and now it barely moves, making it easy to miss alerts. Vibration problems are caused by settings being turned off, Do Not Disturb blocking vibrations, a software glitch, or a failing vibration motor.

Check vibration settings

Android

Settings, Sound and Vibration (or Sound)
Make sure Vibrate While Ringing or Also Vibrate for Calls is toggled On. This controls whether the phone vibrates during incoming calls
Check Vibration Intensity (Samsung) or Vibration Strength: the slider may be set to zero or very low. Increase it and test
Check individual settings: Ring, Notification, and Touch Feedback may each have their own vibration toggle. All three need to be enabled for vibration to work everywhere

iPhone

Settings, Sounds and Haptics
Make sure Vibrate on Ring is toggled On (vibrates when the phone is not in silent mode)
Make sure Vibrate on Silent is toggled On (vibrates when the phone IS in silent mode — this is the one most people need)
Check System Haptics at the bottom of Sounds and Haptics — this controls whether the phone vibrates for UI interactions like toggling switches and keyboard presses. Turn it On if you want haptic feedback

Check Do Not Disturb

Do Not Disturb can suppress vibrations along with sounds. Check if DND is active (crescent moon icon on iPhone, minus-in-circle on Android)
Turn off DND and test vibration. Even with DND on, some modes allow vibration — check the DND settings for vibration behavior

Test vibration directly

Android

Settings, Sound and Vibration, Vibration Intensity — when you change the slider, the phone should vibrate to preview the intensity. If it does not vibrate at all when moving the slider, the motor may be dead
Try toggling between Ring and Vibrate mode using the volume buttons. When switching to Vibrate mode, the phone should produce a vibration confirmation

iPhone

Toggle the physical Ring/Silent switch on the left side of the phone. When switching to silent mode (orange visible), the phone should vibrate once. If it does not vibrate when toggling the switch, the vibration motor is not working
Set an alarm for one minute from now with vibration enabled. When it goes off, the phone should vibrate

Restart the phone

A software glitch can freeze the vibration motor controller. The motor is powered by a software signal, and if the signal process crashes, vibration stops until a restart
Power off completely, wait 15 seconds, power back on. Test vibration immediately after boot

Check accessibility settings

Android: Settings, Accessibility — some accessibility modes override vibration settings. Check for interaction controls, switch access, or custom vibration profiles that may be set to no vibration
iPhone: Settings, Accessibility, Touch — check for any settings that might affect haptic feedback. Also check Settings, Accessibility, Vibration — if this is turned Off, ALL vibration on the phone is disabled regardless of other settings

Check app-specific vibration

If vibration works for some things but not others (for example, calls vibrate but texts do not), the issue is app-specific notification settings:
Android: Settings, Apps, select the messaging app, Notifications — check each notification category. The vibration toggle may be off for specific categories
iPhone: Settings, Notifications, select the app — check if the app supports custom vibration patterns. Some apps do not support vibration in their notifications

Safe Mode test (Android)

Boot into Safe Mode: hold power, long-press Power Off, Safe Mode
In Safe Mode, test vibration by toggling sound modes or changing vibration intensity in Settings
If vibration works in Safe Mode, a third-party app is disabling or interfering with the vibration motor. Exit Safe Mode and uninstall recently installed apps

Software update

Vibration motor control is managed by low-level firmware that can have bugs. Install any pending system updates
If vibration stopped after a specific update, the update may have introduced a bug. Check forums for your phone model to see if others report the same issue

Factory reset

If vibration does not work in any mode and no setting change fixes it, but you have not confirmed a hardware failure, a factory reset eliminates all software causes
Back up data, then Settings, System, Reset, Factory Reset. After the reset, test vibration before restoring apps

Hardware issues

If vibration does not work after a factory reset, the vibration motor itself has failed:

Motor types: Phones use either a rotary motor (ERM — Eccentric Rotating Mass, the traditional buzzing motor) or a linear motor (LRA — Linear Resonant Actuator or Taptic Engine on iPhone, the precise tapping motor). Both types can fail from wear, drop damage, or water exposure
Weak vibration: A vibration motor that is getting weaker over time is wearing out. ERM motors lose vibration strength as the weight becomes unbalanced. LRA motors can lose strength if the spring mechanism fatigues. Replacement restores full vibration
Intermittent vibration: If vibration works sometimes and not others, the motor's connection to the motherboard may be loose. A drop can dislodge the solder point or flex cable connector. A technician can resolder or reseat the connection
No vibration at all: The motor has completely failed or the flex cable connecting it has broken. The vibration motor is a replaceable component on most phones
