When your phone stops vibrating — no vibration for calls, text messages, notifications, alarms, or haptic feedback when typing — you miss alerts and the phone feels unresponsive. The vibration motor (also called the haptic engine or taptic engine on iPhones) is a small physical component inside the phone. The problem can be a software setting, a system glitch, or actual motor failure. Here is how to diagnose and fix it.
Check vibration settings
The most common cause is a setting that has turned off vibration, often without the user realizing it:
iPhone
Go to Settings, Sounds and Haptics
Check that Vibrate on Ring and Vibrate on Silent are both turned on (toggle switches should be green)
Under the ringtone and alert sounds section, check that a vibration pattern is selected — tap Ringtone, then Vibration at the top. Make sure it is not set to None
Check Settings, Sounds and Haptics, System Haptics — this controls the haptic feedback for keyboard taps, toggles, and other system interactions. Turn it on if you want haptic feedback
Check Settings, Accessibility, Touch, Vibration — there is a master vibration toggle here. If this is turned off, all vibration on the phone is disabled regardless of other settings. Make sure it is on
Android
Go to Settings, Sound (or Sound and Vibration)
Check that Vibrate for calls is turned on
Check the vibration intensity settings — Samsung phones have separate intensity sliders for Calls, Notifications, and Touch feedback under Settings, Sound and Vibration, Vibration intensity. Make sure they are not set to zero
Check that Do Not Disturb is not active — DND can suppress vibrations depending on its settings
On Samsung, check Settings, Sound and Vibration, System sound/vibration control — individual toggles control haptic feedback for keyboard, dialing, and charging
Check the Ring/Silent switch (iPhone)
The physical switch on the left side of the iPhone controls whether the phone rings or is silent:
If the switch shows orange, the phone is in silent mode. In this mode, the phone should still vibrate for calls and notifications if Vibrate on Silent is enabled in Settings
Toggle the switch back and forth a few times. Sometimes the switch gets stuck in a position or the contact inside gets dirty, which can confuse the vibration behavior
If the phone vibrates when you toggle the switch but does not vibrate for incoming calls, the issue is likely in the per-app notification settings or the ringtone vibration pattern selection
Restart the phone
A software glitch can cause the vibration motor to stop responding even when all settings are correct. A restart reinitializes the hardware drivers:
Power off the phone completely, wait 10-15 seconds, and turn it back on
After the phone boots, test vibration by toggling the Ring/Silent switch on iPhone (it should vibrate briefly) or by long-pressing the power button on Android until you feel the vibration feedback
Test vibration directly
Confirm whether the vibration motor itself is working or whether the issue is with specific triggers:
iPhone: Toggle the Ring/Silent switch — you should feel a brief vibration. Go to Settings, Sounds and Haptics, and drag the Ringer and Alerts volume slider — the phone should vibrate as you adjust it. Set a timer for 1 minute in the Clock app and let it go off — the alarm vibration uses a strong pattern
Android: Open the Phone dialer app and tap a number — if touch vibration is on, you should feel haptic feedback. Set a timer or alarm and let it trigger. You can also call your own phone from another phone and check whether it vibrates for the incoming call
If vibration works for some triggers (like the Ring/Silent switch) but not others (like incoming calls), the motor is fine and the issue is in notification or app-specific settings
Check per-app notification settings
Individual apps can have vibration disabled in their notification settings:
iPhone: Settings, Notifications, select the app. If the app's alert type is set to deliver quietly or to the Notification Center without sound, vibration may also be suppressed
Android: Settings, Apps, select the app, Notifications. Each notification category can have its own vibration setting. A messaging app might have vibration turned off for its message category while other categories vibrate normally
Check for Do Not Disturb or Focus mode
Active DND or Focus modes suppress vibrations:
iPhone: Check Control Center for active Focus modes (moon icon or other Focus icons). Go to Settings, Focus, and check each mode's schedule and allowed contacts/apps
Android: Pull down the notification shade and check if Do Not Disturb is active. Go to Settings, Sound, Do Not Disturb and check for automatic schedules (time-based, driving, sleeping)
Software update
Vibration motor control is handled by system firmware. A software update can fix bugs that prevent the motor from activating:
Update to the latest iOS or Android version
After updating, restart the phone and check vibration
Reset all settings
If vibration settings appear correct but the motor still does not respond to software triggers:
iPhone: Settings, General, Transfer or Reset iPhone, Reset, Reset All Settings. This restores all system settings to defaults without deleting data
Android: Settings, General management, Reset, Reset all settings
Hardware failure
If vibration does not work at all — not for any trigger, not after a restart, not after a settings reset — the vibration motor or its connection has likely failed:
What is inside: iPhones use a Taptic Engine (a linear resonant actuator) that produces precise haptic feedback. Android phones use either a linear vibration motor or an eccentric rotating mass (ERM) motor. Both are physical components that can wear out or break
Common failure causes:
Drop damage — the motor or its solder connections can break from impact
Water exposure — corrosion on the motor contacts or flex cable
Age and wear — vibration motors are mechanical and have a finite lifespan, though they typically last longer than the phone's useful life
Loose connector — the motor connects to the logic board via a small flex cable and connector. If the connector is slightly dislodged (from a drop or a previous repair), vibration stops
After a repair — if vibration stopped working after a screen or battery replacement, the motor's flex cable may not have been properly reconnected
Replacement
Vibration motor replacement is a straightforward repair. The motor is an inexpensive component (typically a few dollars for the part). The labor involves opening the phone and disconnecting/reconnecting the small motor assembly. On iPhones, the Taptic Engine is one of the first components accessible after opening the phone, making it one of the easier internal repairs.
