Changing an operating system from an open architecture Android to a closed ecosystem iOS is often accompanied by technical difficulties, and the most common of them is the inability to transfer media library. Users are faced with situations where the gallery is empty, the process gets stuck in the middle, or files get corrupted while being copied. This is not just an annoying error, but a consequence of fundamental differences in the file systems and security protocols of the two platforms.

The root of the problem often lies not in a “broken” phone, but in the incompatibility of storage formats or incorrect configuration of network interaction at the time of migration. The data transfer protocol between devices requires strict adherence to the sequence of actions, and the slightest deviation from the algorithm leads to failure. In this article, we will analyze in detail the mechanics of the process so that you understand why the system blocks the transfer, and how to bypass these restrictions.

Google Photos, iCloud and the proprietary utility Move to iOS work on different principles, and understanding these differences is critical for successful migration. Sometimes the problem is solved by a simple reboot, while in other cases manual intervention in the local network access settings is required. Let's look at the main system failure scenarios and methods for eliminating them.

Limitations of the Move to iOS utility and network conflicts

The most popular migration method is using the official application Move to iOS from Apple. However, this is where users most often encounter errors like “Failed to transfer data” or endless hangs at the time estimation stage. The reason lies in the fact that the application creates a temporary secure network Wi-Fi between devices, bypassing your home router.

If your smartphone has mobile data enabled or it is trying to switch to a known Wi-Fi network in the background, the connection with Android-the smartphone has mobile data enabled or is trying to switch to a known Wi-Fi network in the background, connecting to iPhone tears. The system iOS is extremely sensitive to the stability of the communication channel during initial setup. Any interference from third-party applications trying to optimize traffic or switch frequencies may be perceived as a security threat, and data transfer will be immediately stopped.

In addition, there is a nuance with operating system versions. If the device has an outdated version of the OS or the application itself is not updated, the handshake protocol may not take place. Android the OS version or the application itself is outdated Move to iOS is not updated, the handshake protocol may not take place. Network stack different versions of Android work differently, and older implementations may not correctly process requests from new Apple devices.

💡

Before starting the transfer, enable Airplane Mode on Android, and then manually activate only Wi-Fi. This will block the phone's attempts to switch to the mobile network.

It is also worth considering the load on the processor. If you are trying to transfer tens of gigabytes of high-resolution photos while other background services are running, the clipboard may become full. iPhone is busy indexing files at this point, and the additional traffic causes the connection to time out.

⚠️ Attention: Utility Move to iOS works only during the initial setup of the iPhone. If you've already activated your device and can see the desktop, you'll need to do a factory reset or use alternative transfer methods.

HEIC and JPEG format compatibility issues

One ​​technical reason why photos may not display or transfer correctly is the difference in image compression formats. Modern smartphones on Android often by default use the HEIC (High Efficiency Image Coding) format to save space, while older models or specific settings may require the classic JPEG.

Although iOS works great with HEIC, the on-the-fly conversion process during data transfer can cause error if the sender-side compression algorithm differs from the expected Apple standard. This is especially true for phones from Chinese brands, such as Xiaomi, Huawei or Oppo, which use their own add-ons over standard Android and can use proprietary photo processing methods.

If during transfer you see that some of the photos were copied, but some were not, check the camera settings on the source device. Perhaps some of the pictures were taken in Ultra HD or RAWmode, which require more resources for processing and can be skipped by the automatic migration script due to session time limits.

How to change the camera format on Android?

Go to Camera Settings → Saving Format → Select Compatibility or JPEG. This will ensure maximum compatibility when transferred to any device.

Sometimes the problem lies in the metadata EXIF. If the file contains incorrect geolocation data or the shooting date (for example, due to a time zone failure), the file system iOS may reject such a file as damaged when you try to import it into the standard Photos application.

Not enough space in iCloud and local storage

Users often confuse data transfer via cable or Wi-Fi with synchronization via the cloud. If you are trying to upload a photo via Google Photos to iPhone, available space becomes a critical factor. The free plan iCloud is only 5 GB, which is catastrophically small for a modern media library.

When the space in the cloud storage runs out, synchronization stops. You can see photos on the service's website, but they will not appear on the device, since the system blocks the downloading of new files. This is a common mistake: the user thinks that the transfer does not work, when he simply hit the tariff limit.

A similar situation arises with local memory. If 90% of the space is already filled with system files and applications, there will simply be no room left for a new gallery. The operating system will not allow the copying process to complete so as not to cause a critical failure in the device. iPhone 90% of the space is already filled with system files and applications, there is simply no room left for a new gallery. The operating system will not allow you to complete the copying process, so as not to cause a critical failure in the operation of the device.

Transfer method Required space Network dependence Risk of data loss
Move to iOS Locally on iPhone Direct Wi-Fi connection Low (with stable connection)
Google Photos In iCloud or on your phone Internet (mobile/Wi-Fi) Medium (depending on the tariff)
PC (iTunes/Finder) Locally on iPhone USB cable High (risk of overwriting)
Third-party applications Local Local Wi-Fi network Medium (depending on the software)

Check the available space before starting the operation. Go to Settings → General → iPhone Storage and make sure that you have a reserve of at least 20% of the amount of data being transferred. This is necessary for temporary files and system cache to work during import.

Access rights and permissions errors applications

In modern versions Android (starting from 11 and higher), the rules for application access to the file system have been tightened. The utility Move to iOS or any other file manager must be given explicit permission to access all media files.

If you accidentally clicked "Decline" the first time you launched it or the system automatically limited background activity of the application, the transfer process will begin, but will quickly be interrupted when the script tries to read the next folder. This appears as a freeze or sudden shutdown without an error message.

You need to manually check the permissions. Go to Settings → Applications → Move to iOS → Permissions and make sure that access to “Photos and Videos” and “Memory” is fully allowed. Some shells, for example One UI from Samsung, have additional protection "Autorun", which also needs to be activated for stable operation.

⚠️ Attention: On Android 13 and newer, access to files can be divided by type (separately photo, video, audio). Make sure you give permission to all categories of media, not just images.

It's also worth turning off battery optimization for the transfer app. The system Android tends to “kill” processes that actively use the network and processor in the background, considering them energy hogs. Add the application to exceptions or white list.

The specifics of working with folders and hidden files

The file structure Android differs from iOS. On Android, photos can be stored not only in the standard folder DCIM, but also in messenger directories (for example, WhatsApp/Media), downloads or social network caches.

Standard migration tools often scan only the main directories. If your photos are in a folder Download or in a hidden folder starting with a dot (for example, .Nomedia), the transfer algorithm may simply not see them. For the system, this is not a “gallery”, but service or downloaded files.

To solve this problem, before transferring, it is recommended to collect all important images into one folder inside the standard gallery. Use a file manager to move files from deep directories to the root (Albums). This is guaranteed to fall into the scanning area of the utility Move to iOS.

☑️ Preparing files for transfer

Done: 0 / 5

In addition, pay attention to files with non-standard extensions. If you used specific editors, the saved files may have extensions that are iOS not recognized as images (for example .webp in older versions or proprietary editor formats). Such files will be ignored.

Alternative methods: when automation is powerless

If standard tools fail, you have to resort to “manual” transfer. The most reliable, although labor-intensive, method is to use a computer as an intermediate link. Connect Android to your PC, copy the folder DCIM to your hard drive, then connect iPhone and use the app 3uTools or standard Finder (on Mac) to import.

This method allows you to bypass network restrictions and problems with formats, since the computer can act as a converter. You can preview files and discard broken images that could cause automatic transfer to fail.

Another option is to use third-party applications to transfer files over the local network, such as Send Anywhere or Xender. They work on the P2P principle and are not subject to Apple's restrictions during the setup phase. However, with this method, the photos will end up in a separate application, and you will have to manually save them to the system gallery.

⚠️ Attention: When transferring via a computer using iTunes/Finder, remember that synchronization may replace the contents of the folder on the phone with the contents of the folder on the computer. Be careful not to erase existing data on your iPhone.

For large amounts of data (more than 50 GB), using cloud services with a paid subscription is often faster and more reliable than trying to maintain an unstable Wi-Fi connection for several hours. Upload the archive to the cloud on Android, install the application on iPhone and download the data.

💡

If the automatic transfer freezes for more than 10 minutes, do not wait - interrupt the process. Most likely, the connection is lost, and waiting will not lead to success, it will only drain the batteries.

Frequently asked questions (FAQ)

Why does the photo transfer fail at 90%?

Most often this is due to an unstable Wi-Fi connection or the fact that one of the devices is blocked (screen went dark). Make sure both phones have their display settings set to "Never" to turn off the screen, and keep them next to each other without obstructions.

Can I transfer photos after setting up my iPhone?

The official utility Move to iOS only works during the initial setup. If the phone is already activated, you need to either reset it to factory settings (Settings → General → Transfer or reset iPhone → Erase content and settings), or use cloud services and a computer.

Where do photos go after transferring from Android?

They usually end up in the “Recent” album or create a separate album with a name corresponding to the import date. If you used a third-party application, check the folders inside the Files application or in the assistant application itself.

Why did some photos become blurry after transfer?

This can happen if it was not the originals that were transferred, but optimized previews from the messenger cache (WhatsApp, Telegram). Make sure that you copy files from the original camera folder, and not from messenger download folders.

How long does it take to transfer 1000 photos?

When using Move to iOS and a stable connection, it takes from 15 to 40 minutes. The time depends greatly on the size of the files (videos weigh more) and the speed of the processors of both devices. Through the cloud, the process may take several hours depending on the Internet speed.
