Check these first
Do not assume the cause from the symptom alone. First determine whether the issue affects the whole phone, one app, one connection, or one accessory. Work from low-impact checks toward recovery or repair.
- Charge Android and the new iPhone and prepare stable Wi-Fi
- Confirm that the iPhone has enough storage for selected Android data
- Review separate requirements for authenticators, messaging, eSIM, and banking apps
Narrow down the cause
| Scope of the issue | Where to check next |
|---|---|
| Only one app is affected | Check app permissions, updates, storage, cache, and reinstall options |
| The whole phone is affected | Check restart, system updates, free storage, and system settings |
| Other devices have the same issue | Check the network, service, charger, or accessory |
| The issue began after a drop or liquid exposure | Avoid repeated power or charging attempts and contact official support |

Safe step-by-step process
Complete one step at a time and test after each change. Do not change several settings at once.
- 1Back up Android and verify the amount and sync status of photos, contacts, messages, and other data.
- 2During setup on a new or erased iPhone, choose Move Data from Android.
- 3Install Apple’s official Move to iOS app from the official store and connect using the code displayed on iPhone.
- 4Select data and keep both devices powered and untouched until the progress bar on iPhone completes, even if Android appears finished.
- 5Move the phone number or SIM/eSIM and separately transfer WhatsApp, authenticator, banking, and other protected apps.
- 6Do not erase Android until photos, contacts, messages, calls, SMS, and critical apps are verified on iPhone.
Actions to avoid
- Opening other apps, disabling Wi-Fi, or using the phones during transfer
- Starting without enough destination storage
- Erasing Android before verifying authentication recovery
Prevent the issue from returning
- Clean up unnecessary data and verify backups on both platforms
- Keep the old Android phone until verification is complete, then erase it through official settings
