The situation when the migration process from Android to iOS gets stuck in the middle or produces an incomprehensible error causes natural irritation. You bought a new smartphone expecting a seamless transition, but instead you see an endless loading spinner or a connection failure message. This is a common problem that thousands of users face every year when using the “Transfer to iOS” utility (Move to iOS).
There can be many reasons for failure: from banal interference in a wireless network to incompatibility of software versions. Users often attribute everything to “crooked hands” or a faulty device, although the matter lies in the intricacies of communication protocols between two different ecosystems. Understanding the technical background of the process allows you to quickly eliminate obstacles and complete the configuration of the gadget.
In this article, we will look in detail at why content transfer is interrupted, how to bypass memory limitations, and what to do if the application crashes at startup. We will not use general phrases, but will focus on specific technical steps that guarantee the successful transfer of your photos, contacts and message history.
Technical requirements and version compatibility
The first thing you need to check before starting. migration is the compliance of operating system versions. For the correct operation of the application Move to iOS on the device Android OS version must be installed at least 4.0 (Ice Cream Sandwich), although in practice it is better to use devices with Android 9 and higher. On the side iPhone the process is possible only at the initial setup stage, when the device is on the welcome screen.
If you have already activated the iPhone and got to the desktop, the standard method of transferring via the created private Wi-Fi network will not work. In this case the only solution the device is completely reset to factory settings. Many users ignore this requirement, trying to launch the application after the fact, which inevitably leads to a connection error.
⚠️ Attention: The data transfer process is only possible during the initial setup of the iPhone. If the phone is already set up, you will need to reset it via
Settings → General → Transfer or reset iPhone → Erase content and settings.
You should also make sure that the necessary communication modules are enabled on both devices. Wi-Fi and Bluetooth should be are active and the power saving mode on Android is disabled because it may limit the background operation of the network adapter required to create a tunnel between devices. Make sure you don't have Airplane mode enabled on Android, which sometimes activates accidentally.
Before you start migrating, connect both devices to a power source. The process can take anywhere from 15 minutes to several hours depending on the amount of data, and battery drain will interrupt the connection.
Network connection problems and interference
The most common cause of failure is an unstable connection. The utility creates a direct access point (ad-hoc network) between phones, bypassing your home router. If at this moment on Android the device tries to switch to a 4G/5G mobile network or connect to a known Wi-Fi network, the process is interrupted. You must manually disable switching networks in the settings.
In addition, any active connections to other wireless devices may cause interference. If there are microwave ovens, powerful Bluetooth headsets, or other gadgets operating nearby in the 2.4 GHz range, this may jam the signal. It is recommended to move to another room or disconnect unnecessary devices.
Particular attention should be paid to the DNS and proxy settings on Android. If you have ad blocking apps (such as AdGuard) or VPN services installed, they may block local traffic between phones. Before starting the migration, be sure to disable all VPN profiles and temporarily remove applications that filter network traffic.
- 📶 Turn off mobile data (data transfer) on your Android smartphone before starting to search for the code.
- 🚫 Close all background applications on both devices to free up RAM.
- 🔄 Restart both smartphones before trying to connect again.
Lack of free space on the target device
A logical but often ignored reason for failure is the physical lack of space on the new iPhone. The system automatically estimates the amount of data on your old device, but this estimate is not always accurate. Cached files, temporary messenger data and system junk can take up gigabytes that are not taken into account in the rough calculation.
If space runs out during the transfer process, the operation is interrupted without the possibility of resuming from the same point. You will have to start all over again. Therefore, it is critical that the free space on iOS device exceeds the amount of occupied data by Android at least 10-15%.
To check the actual amount of data, go to the Android storage settings. Pay attention not only to photos and videos, but also to the “Applications” section. Often it is heavy games and the cache of social networks that become a stumbling block. The table below shows approximate data volumes for different types of content.
| Data type | Approximate volume (average) | Impact on speed | Risk of failure |
|---|---|---|---|
| Contacts and SMS | < 50 MB | Minimum | Low |
| Photos (1000 pcs) | 2-4 GB | Average | Medium |
| Video (Full HD) | 10-50 GB | High | High |
| Call history | < 10 MB | Minimum | Low |
Always clean up unnecessary files on Android before transferring. This will speed up the process and reduce the risk of errors due to lack of space on the iPhone.
Errors in the "Transfer to iOS" application
The application itself Move to iOS from Google may not work correctly due to an outdated version or conflicts with the manufacturer's shell (for example, MIUI, OneUI or ColorOS). Aggressive power saving systems of Chinese brands often “kill” the data transfer process in the background, considering it suspicious activity.
To avoid this, you need to add the application to the power saving mode exceptions. The path to the settings may vary, but usually it looks like Settings → Battery → Running applications in the background → Move to iOS → No restrictions. It is also worth preventing the system from closing the application when the screen is locked.
If the application crashes immediately after entering the code, try clearing its cache and data. Log in Settings → Applications → Move to iOS → Storage → Clear cache. As a last resort, delete the application and download it again from Google Play, making sure that you download the official version from Google LLC.
Secret method for Xiaomi and Huawei owners
On devices with MIUI and EMUI shells, turning on the developer mode and increasing the animation wait timer often helps, which prevents the system from prematurely closing the data service.
Specifics of transferring data from instant messengers
A separate headache is transferring correspondence history from WhatsApp. This feature is relatively new and requires strict conditions. Firstly, both devices must have the latest version of the messenger installed. Secondly, the phone number must be the same.
Often users forget that to transfer WhatsApp history, you need to select this item specifically in the "Transfer to iOS" utility menu. If you simply transfer the application, the chats will remain on the old phone. The process requires scanning a QR code and may take a significant amount of time due to database encryption.
Some users have reported problems when transferring data from Telegram or Viber. It is important to understand that Apple's native utility only supports history transfer for WhatsApp. For other instant messengers, data (contacts, media) can be transferred as files, but the chat structure will not be saved, since these services store the history on their servers or use other protocols.
⚠️ Attention: When transferring WhatsApp, make sure that there is enough space on the iPhone. A backup copy of chats can weigh much more than it seems, especially if you actively exchange videos and documents.

Alternative methods and manual problem solving
If the standard "Transfer to iOS" method stubbornly does not work, despite all the manipulations, it is worth considering alternatives. For contacts and calendar, the most reliable way is synchronization through your Google account. Add your Gmail account to the iPhone settings (Passwords and accounts), and the data will be pulled up automatically via the cloud.
For photos and videos, you can use Google Photos or Yandex.Disk services. Install the application on your iPhone, log in to your account, and all your media files will be available in original quality or compressed version. This is often faster and more reliable than direct transfer over Wi-Fi, especially for large amounts of data.
For users for whom it is critical to preserve the folder structure and files, there is a method via a computer. Connect Android to PC, copy files, then connect iPhone and use iTunes (or Finder on Mac) to sync photos and videos. Although it takes longer, this method eliminates wireless connection errors.
- ☁️ Use Google Account to seamlessly synchronize contacts and mail.
- 💾 Use cloud storage for photos if direct transfer is gagal.
- 💻 Use a PC as an intermediate link for transferring heavy video files.
Frequently asked questions (FAQ)
Can I transfer data if I have already set up my iPhone?
No, the "Transfer to iOS" function only works during the initial setup stage (the "Applications and Data" screen). If the phone is already activated, you need to perform a hard reset through the menu or use cloud services (Google Photos, Drive) to manually download the data.
Why does the transfer get stuck on the time estimate?
This often happens when there are a lot of small files or damaged media files on Android. Try canceling the transfer, deleting some old or damaged photos/videos on the source and try again. Also check if the device is overheating.
Are installed applications transferred?
The application files themselves (.apk) are not transferred, since the system architectures are different. However, the utility will offer to download free analogues from the App Store, if they exist. Paid applications will have to be purchased again if they do not support a cross-platform license.
What to do if the code is not suitable or is not generated?
Make sure that mobile data is turned off on Android and it is connected to the Wi-Fi network created by the iPhone (it may be called "Move to iOS..."). If the problem persists, restart both devices and make sure they have the latest software updates installed.
Is it safe to interrupt the transfer process?
Interrupting the process is safe for the hardware, but the data will not be partially transferred. You will have to start the process all over again from the beginning. No data on phones is deleted when interrupted unless you initiate a factory reset.
