How to Fix a Phone That Is Not Vibrating or Has Weak Vibration

Published 2026-10-16 · Marion Phone Repair

Your phone no longer vibrates for calls, texts, or notifications — or the vibration is so weak you cannot feel it in your pocket. Vibration problems can be caused by a software setting, a system mode override, or a failing vibration motor. This guide walks through every fix from the simplest setting check to hardware diagnosis.

Check vibration settings

The most common cause of missing vibration is a setting that has been turned off:

iPhone: Go to Settings, Sounds and Haptics. Make sure the Vibrate on Ring and Vibrate on Silent toggles are both on. If both are off, the phone will never vibrate regardless of other settings
iPhone haptic feedback: Settings, Sounds and Haptics, scroll down to System Haptics. Make sure this is on. System Haptics controls the tactile feedback you feel when typing, toggling switches, and interacting with the interface
Android: Go to Settings, Sound and Vibration (or Sounds and Vibration on Samsung). Check that Vibrate While Ringing is on, and that the Vibration Intensity slider is not set to zero. Samsung phones have separate intensity sliders for calls, notifications, and touch feedback — check all three
Android vibration intensity: Some phones let you set vibration intensity from off to strong. Settings, Sound, Vibration Intensity. If any slider is at zero, that vibration type is effectively disabled

Check Do Not Disturb and Focus modes

iPhone: Do Not Disturb and Focus modes can suppress vibration. Open Settings, Focus. Check if any Focus mode is active (the status bar shows a crescent moon for DND or the Focus icon). Tap the active Focus and check its settings — vibration may be silenced by the mode
Android: Settings, Sound, Do Not Disturb. If DND is active, it may suppress vibration for notifications. Check the DND behavior settings to see what it silences
Scheduled modes: If vibration disappears at the same time each day, a scheduled DND or Bedtime mode may be responsible. Check for automatic schedules in your DND or Focus settings

Check the Ring/Silent switch (iPhone)

The physical switch on the left side of the iPhone controls Ring and Silent mode. When the switch shows orange, the phone is in Silent mode
In Silent mode, the phone should vibrate (if Vibrate on Silent is enabled in Settings). If the phone is in Silent mode but not vibrating, check the Vibrate on Silent setting
Flip the switch back and forth a few times. If the switch is worn or has debris inside, it may not register the position correctly. The phone should give a brief vibration each time you toggle from Ring to Silent

Test vibration directly

Confirm whether the vibration motor physically works:

iPhone: Toggle the Ring/Silent switch — the phone should vibrate once when switching to Silent mode. Alternatively, set a timer for 1 minute in the Clock app with vibration. When the timer goes off, it should vibrate
Samsung: Dial *#0*# in the Phone app to open the diagnostic menu. Tap Vibration. The phone should vibrate continuously. This directly tests the motor hardware. Tap the button again to stop
Other Android: Set a short timer with vibration enabled, or call the phone from another phone with vibration on ring enabled. If the phone vibrates for the timer or incoming call, the motor works and the issue is with specific notification settings. If it does not vibrate at all, the motor may be failing

Restart the phone

A simple restart can fix vibration issues caused by a software glitch. The vibration motor is controlled by a system process, and if that process hangs or encounters an error, a restart reinitializes it
If vibration stopped working suddenly without any settings change, a restart is especially likely to fix it

Check app-specific notification settings

If the phone vibrates for some things but not others, the issue is likely in per-app notification settings:

iPhone: Settings, Notifications, select the specific app. There is no per-app vibration toggle on iPhone — vibration follows the Sounds toggle. If Sounds is off for that app, there is no vibration for its notifications
Android: Settings, Apps, select the app, Notifications. Each notification category has its own vibration setting. Tap the category and check if vibration is enabled. Some apps have many categories — a messaging app may have separate settings for messages, calls, and other alerts
In-app settings: Some apps (WhatsApp, Telegram, Signal) have their own vibration settings inside the app that override system settings. Check the app notification settings within the app itself

Update your phone software

Vibration bugs occasionally appear in specific OS versions. Update to the latest version: Settings, General, Software Update (iPhone) or Settings, System, System Update (Android)
If vibration stopped working after a specific update, search online for reports of vibration issues with your phone model and OS version. Known bugs are typically fixed in the next patch

Check accessibility settings

iPhone: Settings, Accessibility, Touch. Check if Vibration is turned off. This master toggle overrides all other vibration settings — if it is off, the phone will never vibrate for anything. Turn it on
Android: Settings, Accessibility. Check for any touch or vibration related settings that may have been changed. Some accessibility features modify vibration behavior

Weak vibration causes

If the phone vibrates but the vibration is noticeably weaker than it used to be:

Check vibration intensity settings: Android phones often have vibration intensity sliders. Settings, Sound, Vibration Intensity. Move the sliders to the maximum. On iPhone, the vibration intensity is not adjustable for standard haptics, but you can choose different vibration patterns: Settings, Sounds and Haptics, then tap a notification type (Ringtone, Text Tone, etc.) and select Vibration at the top to choose a stronger pattern
Case interference: Very thick or padded phone cases can absorb vibration, making it feel weaker. Remove the case and test. If the vibration feels normal without the case, the case is dampening it
Motor wear: Vibration motors are mechanical components that wear out over time. The motors in older phones (3+ years of daily use) may produce noticeably less vibration than when the phone was new. This is gradual and normal
Loose motor: If the vibration sounds different than it used to (rattling, buzzing, clicking) or the phone vibrates asymmetrically (stronger on one side), the motor may have come loose from its mounting. This can happen after a drop. It requires opening the phone to reseat or replace the motor

Types of vibration motors

Linear actuator (Taptic Engine on iPhone, most modern flagship Android phones): These produce precise, crisp vibrations. They are more durable than older motor types and allow different vibration patterns and intensities. Failure in these motors typically means no vibration at all rather than weak vibration
ERM (Eccentric Rotating Mass) motors (older and budget Android phones): These are tiny spinning motors with an off-center weight. They produce a buzzy, less precise vibration. They wear out faster and the vibration weakens gradually as the bearings wear. Common in budget phones and phones older than 2019

Factory reset as a last software test

If all settings are correct, the phone is updated, and vibration still does not work, a factory reset determines whether the problem is software or hardware:

Back up your phone first. Then: Settings, General, Transfer or Reset iPhone, Erase All Content and Settings (iPhone). Or Settings, System, Reset Options, Erase All Data (Android)
After the reset, before restoring any backup, test vibration. If vibration works on a fresh reset, something in your backup or installed apps was causing the issue. If vibration still does not work after a factory reset, the motor hardware has failed

When the vibration motor needs replacement

If vibration does not work at all — not for calls, not for the silent switch, not in Samsung diagnostic mode — and a restart, settings check, and factory reset did not fix it, the vibration motor or its connection to the motherboard has failed. Common causes include water exposure corroding the motor contacts, a drop disconnecting the motor flex cable, or simple age-related motor failure. Marion Phone Repair can test the vibration motor, check the flex cable connection, and replace the motor if it has failed.
