Not sure where the fault is?
iPhone · AirDrop

AirDrop cannot find the other device

Turn on Wi-Fi and Bluetooth on both Apple devices, move them nearby, set the receiver to Contacts Only or Everyone for 10 Minutes, and restart both devices. Personal Hotspot can interfere with the local discovery path.

iPhone · Apps

An iPhone app keeps closing, freezing or will not open

Close and reopen the app, restart iPhone, update the app and iOS, then delete and redownload the app last. Deletion can remove data stored only inside that app.

iPhone · CarPlay

CarPlay will not connect to iPhone

Confirm the vehicle and country support CarPlay, unlock iPhone, test the correct USB port and cable or enable Wi-Fi/Bluetooth for wireless CarPlay, then restart the phone and car. Forget the car and set it up again only after those checks.

iPhone · Messages

iMessage activation behaves incorrectly or produces the wrong result

A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.

Open record
iPhone · Messages

iMessage activation is not working

A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.

Open record
iPhone · Messages

iMessage activation is unusually slow or delayed

A delay can come from capacity, weak signal, background work, protection or a service wait; measuring the exact stage prevents the wrong repair. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.

iPhone · Messages

iMessage activation keeps disconnecting or working intermittently

Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.

Open record
iPhone · Messages

iMessage activation stopped working after an update, outage or hardware change

A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.

Open record
iPhone · Messages

iMessage activation works only on one app, network, account or location

When a phone or tablet function changes with the app, network, account or location, that context is the first repair boundary. This record isolates iMessage activation through carrier SMS and date/time versus Apple Account, network and activation state.
