If the volume buttons, Ring/Silent switch, or Side Switch aren't working

On an iPhone, the volume buttons and Ring/Silent switch are on the left side of the device. The buttons on other iPhone models are similar. On an iPad, the volume buttons and Side Switch are on the right side of the device.

If any of these buttons or switches aren't working, follow these steps. After each step, see if you still need help:

1. Unlock your device. Some buttons don't work from the Lock screen.
2. Check for debris or dirt around the button or switch and clean it with a soft cloth.
3. Remove all protective films and cases that might interfere with the button or switch.

What you need

Make sure that both devices can use AirDrop:

• On Mac computers, choose Go from the menu bar in the Finder. If the Go menu includes AirDrop, that Mac can use AirDrop.
• On iOS devices (iPhone, iPad, or iPod touch) open Control Center by swiping up from the bottom of the screen. If AirDrop is in Control Center, that iOS device can use AirDrop.

Tips for sending items

If you don't see the recipient in the AirDrop window or sheet:

• Make sure that both devices have AirDrop turned on and are within 30 feet (9 meters) of each other.
• If you're sending to an iPhone, iPad, or iPod touch:
  • Your Mac needs to be a 2012 or newer model with OS X Yosemite or later.
  • The iOS device must have Personal Hotspot turned off in Settings > Cellular.
• If you're sending to a Mac:
  • If the receiving Mac is using OS X Mavericks, Mountain Lion, or Lion, it needs to have an AirDrop window open: choose Go > AirDrop from the menu bar in the Finder.
  • If the receiving Mac is a 2012 or older model, click “Don't see who you're looking for?” in the AirDrop window or sharing sheet of the sending Mac. Then click “Search for an Older Mac.”
  • Find out if the Mac has “Block all incoming connections” turned on in Security & Privacy preferences. A Mac won't receive items using AirDrop if this setting is turned on.
• If AirDrop on the receiving device is set up to receive items from contacts only, make sure that both devices are signed in to iCloud. Also make sure that the email address or phone number associated with your Apple ID is in the Contacts app of the receiving device.
