Changing an ecosystem is always stressful for the user, especially when it comes to migrating personal data. You bought a new one iPhone, charged it, turned it on, reached the setup stage and launched the application Move to iOS. But instead of a smooth transition, you see an error message, an infinite wait, or a sudden connection loss. This is a common situation that thousands of people face every day when trying to switch from Android to iOS.
The reasons for the failure can be trivial, for example, an unstable Wi-Fi signal, or technically complex, such as incompatibility of operating system versions. Users often blame the application itself or “crooked hands,” although the problem lies in hidden security settings or the peculiarities of the transmission protocols. Understanding the mechanics of the process helps to avoid wasting time and nerves.
In this article we will analyze in detail exactly why your data transfer may have failed, and we will offer specific action algorithms for each type of error. We will not use general phrases, but will focus on the technical nuances that really affect the success of the content migration operation between two different platforms.
Problems with the network connection and the Wi-Fi protocol
The most common reason for failure lies in the organization of the wireless connection. Application Move to iOS does not use your home router to transfer files. Instead, iPhone creates its own temporary secure Wi-Fi network, to which the Androidsmartphone must connect. If your Android phone is set to automatically return to a known network or has smart switching features enabled, it may constantly lose connection with the iPhone.
⚠️ Attention: If mobile data is enabled on Android, it may conflict with the network being created. Before starting the transfer, be sure to disable data transfer via the SIM card in the notification shade.
In addition, many modern smartphones use technology Wi-Fi Direct or the 5 GHz frequency by default, while the network created by the iPhone can operate in the 2.4 GHz range. This leads to the fact that the devices simply “do not see” each other or the connection is terminated immediately after the start of transmission. It is also worth checking whether the power saving mode is enabled on Android, which aggressively turns off the Wi-Fi module in the absence of active traffic.
Sometimes the problem is solved by simply restarting the network settings. Try to forget all saved networks on your Android device before starting the procedure. This will force the phone to search only for the single network that your new gadget from Apple broadcasts, eliminating the possibility of automatically switching to your home router with a password.
Before starting the transfer, turn on airplane mode on Android, and then manually activate only Wi-Fi. This will block all unnecessary radio modules, including Bluetooth and the mobile network, that may cause interference.
Mismatching versions of operating systems and applications
Software is the second most important risk factor. For the migration utility to work correctly, the current version of the application must be installed on the Android device Move to iOS. Developers regularly update encryption protocols and data compression methods, so old versions simply cannot “shake hands” with new versions. iOS.
A similar situation is observed on Apple’s part. If your new iPhone was released a long time ago and is in the warehouse with the old version pre-installed iOS (for example, iOS 14 or 15), and you are trying to connect a modern flagship on Android 13 or 14 to it, a protocol conflict may occur. In this case, you must first complete the initial setup of the iPhone, update it through iTunes or Finder to the latest available version, reset the settings to factory settings, and only then try the transfer again.
| Component | Minimum requirement | Recommended version | Risk failure |
|---|---|---|---|
| Android OS | 4.0 (Ice Cream Sandwich) | Android 10 and higher | High on older versions |
| iOS | 9.0 | Latest stable | Average with a large difference in versions |
| Move to iOS | Any from the Play Market | Latest from the Play Market | Critical when outdated |
| Free space | Equal to the amount of data | +20% of stock | High when there is a shortage places |
Do not forget to check for updates not only for the system, but also for the application itself in the store Google Play. Sometimes an application's cache may contain erroneous data that interferes with the connection. In this case, it helps to completely clear the cache and data of the “Move to iOS” application in the Android settings before relaunching.
Memory limitations and size of transferred data
The logic of the transfer app is simple: it copies data one to another. If your old Android smartphone has 120 GB of storage space and you bought a 64 GB iPhone, the process will fail before it even starts or stop halfway through. The iOS system does not know how to compress data on the fly so that it fits into a smaller volume; it only optimizes the formats of some files.
The situation with media content is especially critical. Photos and videos take up the lion's share of space. Many users do not take into account that system files and pre-installed applications on the iPhone also take up space (about 10-15 GB). Therefore, the actual available space is always less than stated in the specifications. If the difference in volumes is minimal (for example, 118 GB of data on a 128 GB device), there is a high risk of failure due to temporary files created during the copy process.
⚠️ Attention: Do not try to transfer everything if the data volume is close to the limit. It is better to manually delete unnecessary videos or large files before migration to create a security buffer of at least 10-15% of the iPhone's memory.
It is also worth considering the structure of the file system. Android uses a different file system than iOS's APFS. Additional temporary space may be required when converting metadata and file indexes. If the memory is full, the processor of the new phone may not have enough resources to buffer the data stream, which will lead to freezing of the setup interface.
☑️ Check before transfer
Conflicts of third-party software and antiviruses
The Android ecosystem is open to installing software from any source, which often leads to conflicts at the network driver level. Third-party antiviruses, firewalls, traffic managers or memory cleaners may block the creation of a local connection that initiates iPhone. For such apps, any attempt by the device to create its own access point without the participation of the router looks like suspicious activity.
In addition, some smartphone manufacturers (for example, Xiaomi, Huawei, Samsung) have their own aggressive battery optimization and memory management systems. They can forcefully kill the application process Move to iOSif it runs in the background for too long or consumes a lot of radio module resources. This looks like a sudden connection loss for no apparent reason.
To avoid this, you need to add the migration application to the power saving system exceptions. Go to the battery settings, find the application and select the “No restrictions” or “Do not optimize” mode. Also temporarily disable any VPN services, as they redirect all traffic through the tunnel, breaking the local connection between devices.
Hidden developer settings
In some cases, enabled USB debugging or developer mode on Android may interfere with the operation of the Wi-Fi module in specific modes. Try completely disabling developer mode before starting the transfer.
Specifics of transferring messages and call history
One of the most painful topics is transferring correspondence history. Encryption protocols in WhatsApp, Viber and Telegram differ on different platforms. Apple's standard tool allows you to transfer WhatsApp chat history, but only if strict conditions are met: both devices must have the latest versions of the application, and the process must go through the Move to iOS utility, and not through backup to Google Drive or iCloud separately.
SMS messages and call history are transferred quite reliably, but often users are faced with the fact that after transferring numbers are displayed incorrectly or are broken into duplicates. This is due to differences in contact storage formats (vCard versions may differ). If you used non-standard calls or SMS applications on Android, their databases may not be considered a standard iOS converter.
For instant messengers that do not support direct transfer (for example, Viber or Signal at the time of writing), the only way is to create a backup copy on the old device and try to restore it on the new one, although success is not 100% guaranteed. In the case of Telegram the problem is easier to solve, since the history is stored in the cloud, but secret chats cannot be transferred due to their architecture.
⚠️ Attention: Two-factor authentication in instant messengers can block login on a new device if you do not remember the password for the cloud backup or do not have access to the phone number to receive SMS. Make sure that the SIM card is active and receiving calls.
Direct transfer of WhatsApp history is only possible during the initial setup of the iPhone. If you have already set up your phone, you will have to reset it to factory settings to activate this feature.
Alternative methods and manual copying
If the automatic method via Wi-Fi constantly gives an error, do not despair. There are workarounds that take more time but are often more reliable. The simplest option is to use cloud services. Upload your contacts, calendars, and notes to your Google Account on Android, then add the account in your iPhone's settings. Synchronization will pull up all the data without the need to directly connect devices.
Services like Google Photos or Yandex.Diskare great for photos and videos. Install the app on your iPhone, log in to your account, and all your photos will be available in the cloud. You can set up automatic saving of new photos to your phone gallery, if space allows. This eliminates the need to keep two phones side by side for hours.
To transfer large files (movies, documents), you can use a computer as an intermediary. Connect Android to your PC, copy the files to a folder, then connect your iPhone and use the app Apple Devices (formerly iTunes) or Finder to transfer the content to the appropriate memory sections. Although this is less convenient than the wireless method, it gives full control over the process and allows you to see the progress of the copy.
The path to manually add a Google account to the iPhone:
Settings → Mail → Accounts → New account → Google
Using third-party apps for PC, such as AnyTrans or MobileTransis also an option, but requires caution. These apps are paid and may have trial limitations. However, they can often convert data formats on the fly, which solves the problem of incompatibility of some file types.
Use your computer to transfer your music. Files not purchased from the iTunes Store are not automatically transferred through Move to iOS. They need to be transferred manually through the cable and the device management app.
Frequently asked questions (FAQ)
Is it possible to transfer data if the iPhone is already configured and in use?
No, the “Transfer data from Android” function is only available during the initial setup stage (“Hello”). If you're already using the phone, you'll have to do a hard reset (Settings → General → Transfer or reset iPhone → Erase content and settings) and start the process again. Or use cloud services and manual copying.
What to do if the code does not appear on the Android screen?
Make sure the “Transfer from Android” screen is open on your iPhone. If the code does not appear, relaunch the Move to iOS app on Android. Also check to see if your Android has Do Not Disturb mode or ad blocking enabled, which may be blocking pop-up input windows.
Are apps transferred from Android to iPhone?
App files themselves (APKs) are not transferred as they are not compatible with iOS. However, Move to iOS tries to find free versions of these apps in the App Store and automatically starts downloading them. Paid applications will have to be purchased again if they are in the Apple store, and progress in games will be transferred only if the game supports a cross-platform account (for example, through Facebook or Google Play Games).
How long does data transfer take?
The time depends on the amount of information. Transferring contacts and settings takes minutes. Transferring 50 GB of photos and videos may take 1 to 3 hours. It is important not to interrupt the process and keep both devices close to the charger, since active operation of the Wi-Fi module quickly drains the battery.
Why does the transfer freeze at the “Time Estimation” stage?
This means that the application analyzes the volume of files. If there are a lot of files (thousands of photos), this stage can last a long time. If it hangs for more than 15 minutes, most likely the connection has been hidden. Interrupt the process, reboot both phones and try again, after deleting some of the data or clearing the cache.
