It's incredibly frustrating when AirDrop just won't work. Let's troubleshoot this step-by-step. Since you're hitting "not found device," it's usually a discovery or connection issue.
Here is a checklist to fix it, starting with the quickest fixes:
1. The Basic "Is It On?" Check (Both Devices)
- Wi-Fi & Bluetooth: Both must be turned on. Go to Control Center and make sure both icons are blue/active. AirDrop uses both, not just Bluetooth.
- Personal Hotspot: If either device has Personal Hotspot turned on, turn it off. Hotspot hijacks the Wi-Fi and Bluetooth channels that AirDrop needs.
2. Discovery & Visibility (The Most Likely Fix)
On the device you are trying to send to, check their AirDrop settings:
- Go to Settings > General > AirDrop.
- Set it to "Everyone" (or "Everyone for 10 Minutes" in newer iOS versions).
- *Why:* If it's set to "Contacts Only," the devices won't see each other if there is a glitch in contact linking, or if you aren't in their contacts list with the correct Apple ID email/phone.
3. The "Hidden" Hotspot Setting (iOS/iPadOS)
This is a common culprit. Even if your Personal Hotspot is off, the setting to use Wi-Fi/Bluetooth for other devices might be interfering.
- Go to Settings > Personal Hotspot.
- If you see "Allow Others to Join," make sure it is set to Off.
- If it's on, turn it off, wait 10 seconds, and try AirDrop again.
4. Check the Receiving Screen
When someone tries to send you a file, your device usually wakes up the screen to ask "Accept" or "Decline."
- Is the screen locked? If the receiving device's screen is locked and asleep, it might not show the prompt (especially on older iOS versions). Keep the receiving device unlocked and on the Home Screen while you try to send.
5. The "Cross-Platform" Issue (Mac to iPhone / iPhone to Mac)
- Handoff: Make sure Handoff is enabled. On iPhone/iPad: Settings > General > AirPlay & Handoff > Handoff ON. On Mac: System Settings > General > AirDrop & Handoff > Handoff ON.
- Sign-in: Ensure both devices are signed into iCloud with the same Apple ID (if using contacts only) or that they are both discoverable.
6. The "Nuclear" Options
If the above doesn't work:
- Toggle Airplane Mode: Swipe into Control Center, turn on Airplane Mode, wait 10 seconds, turn it off. This resets the radios.
- Restart Both Devices: A simple restart fixes 90% of these weird handshake issues.
- Forget & Reconnect (Mac Users): If sending to a Mac, sometimes the Mac gets stuck. On the Mac, go to System Settings > General > AirDrop & Handoff, and toggle "AirDrop" off and on.
Try this:
Set the receiving device to "Everyone" , make sure Personal Hotspot is off on both, restart both phones, and try again. That usually breaks the logjam.
