Your phone’s vibration most likely stopped working because of a settings change, not a hardware failure. A software update, a toggle you accidentally flipped, or a focus mode running in the background can all silently disable haptic feedback. The fix usually takes less than a minute once you know where to look.
Check Your Vibration Settings First
The most common cause is a setting that got switched off, sometimes without you realizing it. Both iPhone and Android have multiple vibration toggles scattered across different menus, and it only takes one of them being off to kill all haptic feedback.
On iPhone: Open Settings, then tap Sounds & Haptics. Tap Haptics and make sure it’s not set to “Never Play.” You have four options: Always Play, Play in Silent Mode, Don’t Play in Silent Mode, and Never Play. If someone handed you their phone, or if you were adjusting volume and scrolled too far, this setting may have changed. When Haptics is set to Never Play, you won’t feel vibrations for incoming calls, texts, or any alerts.
On Android: Open Settings, tap Accessibility, then Vibration & haptics. There’s a master toggle called “Use vibration & haptics” that controls everything. Below it, you’ll find individual switches for ring vibration, notification vibration, touch feedback, and alarm vibration. Any one of these can be turned off independently, so check each one.
Focus Modes and Do Not Disturb
If your iPhone runs iOS 15 or later, Do Not Disturb is now part of a broader system called Focus. When any Focus mode is active, it silences calls, alerts, and notifications, which includes vibration. You might have a Focus mode scheduled to turn on automatically at certain times or locations without remembering you set it up. Swipe into Control Center and check whether a Focus icon is active. On Android, the equivalent is Do Not Disturb under the Sound settings, which can similarly suppress vibrations on a schedule.
A Software Update May Have Reset Things
OS updates are a well-documented culprit. After the iOS 18 update, multiple iPhone 15 Pro Max users reported losing all notification vibrations while the phone was in silent mode. The vibrations worked when the phone was unlocked and on the home screen but stopped completely when the screen was off and the phone was locked. Similar reports surfaced after iOS 17.1.1, where haptic feedback changed character entirely, feeling aggressive or buzzy, with no way to adjust vibration patterns for individual apps.
If your vibration disappeared right after an update, try a simple restart first. Some users found that updating again to the next minor release (for example, going from iOS 18 to 18.1.1) restored normal haptic behavior. You can also reset just your sound settings by going to Settings, General, Transfer or Reset iPhone, then Reset, and choosing Reset All Settings. This won’t delete your data but will return sound and haptic preferences to their defaults.
Battery Saver and Power Modes
Low Power Mode on iPhone reduces background activity to stretch your battery, and haptic feedback is one of the features that can be affected. Apple has acknowledged that haptic feedback “might affect the battery life of your iPhone,” which is why some power-saving guides recommend disabling it. If your phone dropped below 20% and triggered Low Power Mode automatically, vibration may have been dialed back or turned off. Check whether the battery icon in your status bar is yellow, which indicates Low Power Mode is on, and toggle it off in Settings under Battery.
Android’s Battery Saver works similarly. Some manufacturers restrict vibration intensity or disable touch feedback entirely when the phone enters a power-saving state. Once you charge up and turn off the saver, vibration should return.
Testing Whether the Hardware Still Works
Before assuming your vibration motor is broken, you can test it directly. On Samsung Galaxy phones, open the phone dialer and type *#0*#. This opens a hidden diagnostic menu with a “Vibration” button that triggers the motor immediately. If the phone vibrates, your hardware is fine and the problem is software. You can also download the Samsung Members app, go to Diagnostics, then Phone Diagnostics, and select Vibration.
On iPhones, there’s no built-in diagnostic code, but you can test the motor by going to Settings, Sounds & Haptics, and tapping any vibration pattern under Ringtone. Your phone should vibrate as a preview. Third-party apps like Haptic Testing (available on the App Store, requires iOS 16 or later) let you trigger every type of haptic feedback the phone can produce, which helps pinpoint whether certain vibration types work while others don’t.
When It Really Is the Hardware
Modern smartphones use one of two vibration motor designs. Older and budget phones typically use an eccentric rotating mass motor, which spins a small unbalanced weight on a tiny DC motor to create vibration. Newer flagship phones use a linear resonant actuator, which moves a magnetic mass on a spring (similar to how a speaker works) for faster, more precise feedback. Apple’s Taptic Engine is a version of this design.
Both types can fail. Rotating mass motors wear out over time as the spinning mechanism degrades. Linear actuators are more durable but can stop working if the internal spring loses tension or if the voice coil burns out. A drop can also dislodge the motor from its mounting or break a solder connection on the circuit board.
Signs that point to hardware failure rather than a software glitch: the motor works intermittently (vibrates sometimes but not others), produces a weak or rattling vibration compared to what it used to feel like, or makes a faint buzzing sound without any actual tactile feedback. If the diagnostic test above produces no vibration at all and you’ve confirmed every software setting is correct, the motor itself has likely failed and needs physical repair.
