Your phone is not vibrating, so calls and texts slip past you in silence. You glance down ten minutes later and find three missed calls, with no idea how long that has been happening. The good news is that most dead vibrations come from a setting, not a broken phone. A switch got flipped during an update, a Focus schedule is still running, or one app lost its permission. This guide walks you through the fixes in the order that solves the problem fastest, starting with a 60-second test that tells you if your motor works at all.

Start With a 60-Second Buzz Test
Before you change a single setting, find out if your phone can vibrate at all. If the motor buzzes somewhere, your fix is in the settings. If it buzzes nowhere, you are probably looking at hardware.
Try three quick checks: call yourself from another phone with the ringer set to vibrate, type a few words with keyboard haptics on, and set a ten-second timer. Note which ones buzzed. A phone that vibrates for the keyboard but not for calls has a notification problem. A phone that vibrates for nothing has a motor or system problem.
1. Turn the Main Vibration Switches Back On
This sounds obvious, and that is exactly why it catches so many people. A software update, a fresh phone setup, or a curious child can flip these switches without you noticing.
On iPhone, open Settings, then Sounds and Haptics, and make sure Play Haptics in Ring Mode and Play Haptics in Silent Mode are both on. On older iPhones the same screen says Vibrate on Ring and Vibrate on Silent.
On Android, open Settings, then Sound and Vibration. Turn on Vibrate for calls, and check that your sound mode is set to Vibrate rather than Mute, which kills vibration on many Android phones. Test with a call from another phone after each change so you know which switch did the trick.
2. Check iPhone System Haptics and Your Vibration Pattern
iPhone has two traps the main screen does not show you. The first is System Haptics, the master switch for touch feedback across the whole phone. Go to Settings, then Sounds and Haptics, and scroll to the bottom. If System Haptics is off, your phone loses keyboard buzz, lock buzz, and several alert vibrations at once.
The second trap is the vibration pattern itself. On that same screen, tap Ringtone, then Vibration at the top. If the pattern is set to None, your phone will ring but never buzz for calls, even with every other switch on. Pick Default, then do the same check under Text Tone, since call and text patterns are set separately.
3. Raise the Vibration Intensity on Samsung and Pixel
Some Android phones let you slide vibration strength, and a slider sitting at zero feels exactly like a dead motor. Samsung phones have a Vibration intensity slider under Settings, then Sounds and Vibration. Drag it up and test again.
Pixel phones hide a similar control under Settings, then Sound and Vibration, then Vibration and Haptics, with separate toggles for calls, notifications, and alarms. Push any intensity slider to at least the middle before you decide the motor is broken. A weak buzz you can barely feel in a loose pocket is a different problem from no buzz, and the fix is free.
4. Look for a Focus or Do Not Disturb Schedule
Focus modes are the number one silent culprit on modern phones. You set up a Work or Sleep schedule months ago, forgot about it, and now it mutes vibrations at set hours.
On iPhone, open Settings, then Focus, and tap each mode you see. Check the schedule at the bottom of each one. On Android, open Settings, then Sound and Vibration, then Do Not Disturb, and look for automatic rules and schedules. Turn off any schedule you do not recognize, then test again. If your phone only stops vibrating at certain hours, a schedule is almost certainly the cause.
Simple idea: Before you dig through menus, check the clock. If the silence always starts at the same time of day, a schedule is doing it, not your phone.
5. Fix Vibration for One App at a Time
Sometimes the phone vibrates for calls but not for one app, or the other way round. That points at per-app settings, not the global switches. On iPhone, open Settings, then Notifications, tap the app, and make sure Sounds is on, then check that app’s vibration pattern under Sounds and Haptics, since a pattern of None silences that app alone.
On Android, open Settings, then Notifications, then App notifications, and tap the app that stays silent. Inside, categories like Messages or Calls each carry their own vibration toggle, and one can be off while the rest work. WhatsApp deserves a special check: open a chat, tap the name at the top, then Notifications, and confirm Vibrate is set to Default rather than Off.
6. Turn Off Battery Saver and Check Power Modes
Power saving modes trim features to stretch battery life, and haptics are often first on the chopping block.
On iPhone, open Settings, then Battery, and turn off Low Power Mode. On Android, open Settings, then Battery, then Battery Saver, and turn it off. Samsung owners should also check Device Care, then Battery, then Background Usage Limits, because a sleeping app cannot vibrate for new messages. Test with a call. If the buzz comes back, you have your answer.
7. Stop Your Watch or Car From Stealing the Buzz
Your phone might be vibrating just fine, except the alert is going somewhere else. A smartwatch paired to your phone often takes over notifications, so your wrist buzzes while your phone stays still. Turn off wrist alerts for a day as a test. If the phone buzzes again, the watch was the thief.
Bluetooth audio devices cause a related problem: when your phone is connected to earbuds, a speaker, or your car, some alerts route to that device instead of the phone motor. Disconnect Bluetooth for a minute and test. This is the same class of problem covered in our guide to Can’t Hear Your Caller? 8 Fixes That Bring Sound Back. If disconnecting restores the buzz, forget and re-pair the device.
8. Restart, Update, and Test in Safe Mode
When settings look right but nothing buzzes, suspect the software. Start with a plain restart, which clears the temporary glitch that kills haptics after an update. If that fails, install any pending system update, since updates often include a fix for exactly this kind of bug.
Android owners get one more powerful test: Safe Mode. Hold the power button, then long-press Power Off and tap Safe Mode. In Safe Mode only built-in apps run, so if vibration works there, a third-party app is blocking it. Restart normally to leave Safe Mode, then uninstall recently added apps one at a time, starting with battery savers and notification managers.
9. When the Motor Itself Is the Problem
If your 60-second test showed no vibration anywhere, and every setting above checks out, the motor may be dead. The signs are clear: the buzz faded over weeks until it vanished, it rattles when it does fire, or it died right after a drop or a swim. Water damage and hard drops are the two most common killers.
Samsung owners can run a built-in motor test by opening the Phone app and dialing *#0*# then tapping Vibration. If the test produces nothing, that points firmly at hardware. iPhone owners have no built-in test, so the keyboard and timer checks from the start of this guide are your best evidence.
What a fix might cost you in the US:
- Every setting fix in this guide: $0
- Thinner case if a rugged case is muffling the buzz: $10 to $30
- Third-party vibration motor replacement: $49 to $129
- Apple out-of-warranty iPhone repair: $99 to $379 depending on model
- AppleCare+ incident fee: $29 for screen damage, $99 for other damage
- Carrier insurance deductible: $99 to $249 depending on your plan
- New budget Android phone if repair is not worth it: $150 to $300
One last accessory check: try the phone out of its case for a day, since a thick case can muffle a weak motor enough that you miss it in a pocket. The same logic applies to Music Keeps Pausing? 9 Fixes That Stop It.
Conclusion
Most silent phones are fixed in under ten minutes once you know where to look. Run the buzz test first, then work through the global switches, the hidden pattern and intensity settings, and the Focus schedules that quietly take over.
If nothing here brings the buzz back, take your test results to a repair shop. Tell them the motor fires nowhere, not even for the keyboard or a timer, and you have already ruled out settings and software.
