Changing a smartphone is always an exciting moment, which is often overshadowed by the fear of losing important information. You don't have to worry about contacts, photos or chat history remaining on your old device. Modern technologies make it possible to migrate content in just a few touches, preserving the folder structure and application settings.
There are many ways to do this data transfer, from built-in operating system functions to specialized third-party utilities. One of the most popular solutions is the app Copy My Data, which has proven itself to be a simple and reliable tool. However, for the process to go smoothly, it is important to understand not only the sequence of actions, but also the technical nuances of working with wireless networks.
In this article we will analyze in detail the algorithm for working with the app Copy My Data, compare it with other methods and answer questions that arise from users when changing devices. You will learn how to prepare both gadgets for the procedure and what to do if the file transfer freezes in the middle of the process.
Preparing devices and creating a backup copy
Before starting any information migration operation, it is critical to ensure that both devices are ready to go. This applies not only to battery charge, but also to software status. Make sure that both smartphones have the latest version installed Androidas older firmware may have vulnerabilities in the network protocols used for transmission.
It is strongly recommended that you create a full backup on your old device before using third-party applications. This will serve as insurance in case an unexpected failure occurs during the synchronization process. You can use cloud services or local storage to save your most valuable files.
⚠️ Attention: Make sure that the module is enabled on both devices
Wi-Fiand they are connected to the same wireless network. Different frequencies (2.4 GHz and 5 GHz) can sometimes prevent devices from being detected by each other on the local network.
Check the available space on your new phone. If you plan to transfer several gigabytes of photos and videos, the internal memory of the target device should have adequate reserve. Clearing the cache or deleting unnecessary applications before starting the procedure is a smart step.
☑️ Ready to transfer
Instructions for using the Copy My Data application
The process of working with the utility Copy My Data is intuitive and does not require deep technical knowledge. First you need to download and install the application from the official store Google Play on both smartphones. After launching the app on both devices, accept the terms of the license agreement.
On the old phone, select the “Send Data” option, and on the new one, “Receive Data”. The application will automatically scan the local network and display the name of the receiving device in the list of available targets. Click on the name of the new smartphone to initiate the connection.
Next you will be asked to select content types to migrate. You can tick contacts, calendar, photos and videos. After confirming the selection, the transfer process will begin, which will be displayed as a percentage on the screen of both devices.
Path to network settings: Settings → Connections → Wi-Fi → AdvancedThe time required to complete the operation directly depends on the amount of information transferred and the speed of your router. Do not minimize the application or lock the smartphone screen during the active transfer phase, as this may break the connection.
If the process is frozen at 99%, try temporarily disabling mobile data (4G/5G) on both devices, leaving only Wi-Fi active. This will force the system to use the local channel without attempting to access the global network.
Alternative methods of transferring information
Although Copy My Data is a convenient tool, it is not the only one on the market. Smartphone manufacturers often offer their own solutions that can work faster by optimizing for specific hardware. For example, the ecosystem Samsung uses the application Smart Switch, and Xiaomi — Mi Mover.
A universal solution for any pair of Android devices is the built-in recovery function on first setup. When you turn on your new phone for the first time, the system will offer to copy apps and data from your old device via cable or wirelessly. This method often turns out to be more stable than third-party software.
For users deeply integrated into Google services, cloud synchronization may be the best option. Contacts, notes and calendars are saved in your account Google automatically, and photos can be uploaded via Google Photos. When you log into the same account on a new device, all data will be updated automatically.
| Method | Speed | Complexity | Data type |
|---|---|---|---|
| Copy My Data | Average | Low | Contacts, Photos, Video |
| Google Account | Depends on the Internet | Minimum | Contacts, Settings |
| USB Cable (adapter) | High | Medium | All file types |
| Branded utilities | High | Low | Applications, Data |
Solving common problems and errors
Often users are faced with a situation where devices do not see each other on the network. Most often, the reason lies in the security settings of the router or client isolation AP Isolation. If this feature is active on the router, devices on the same network cannot communicate directly.
Another common problem is interruptions in transfers on large files. High-definition video files may cause the connection to time out if the Wi-Fi signal is unstable. In such cases, it is recommended to bring both phones closer to the router or use the cable transfer method, if supported.
⚠️ Attention: If the application displays the “Connection Failed” error, check whether the “Power Saving” mode is activated on one of the devices. This mode often limits background network activity, which blocks migration utilities from working.
If contacts were transferred in duplicate, do not panic. Most modern address books have a duplicate merge feature. Go to the Contacts app settings and select the "Merge duplicates" option to clear the list.
What to do if SMS messages are not transferred?
The standard Copy My Data app often does not support the transfer of SMS and MMS text messages due to Android security limitations. For this purpose, it is better to use specialized utilities such as SMS Backup & Restore or proprietary solutions from the manufacturer of the new phone.
Data security during wireless transfer
Using a local Wi-Fi network for data transfer is considered a fairly safe method, since the information does not leave the confines of your home or office router. However, if you are on a public network (cafe, airport), using such applications can be risky.
The protocols used in applications like Copy My Datausually do not encrypt end-to-end traffic using complex algorithms. An attacker located on the same network could theoretically intercept data packets. Therefore, it is better to use a cable or encrypted cloud storage to transfer confidential information.
After completing the transfer process, be sure to delete the application from your old device if you do not plan to use it in the future. This will reduce the attack surface and free up memory space. Also check the access rights that were given to the app before deleting it.
⚠️ Attention: Application interfaces and menu names may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). Always check the official manuals for your specific smartphone model.
The most secure way to transfer sensitive data is to use a physical USB cable or encrypted cloud storage, rather than open Wi-Fi networks.
Completing the migration and checking integrity
After the progress indicator reaches 100%, do not rush to immediately reset your old phone to factory settings. Take the time to thoroughly check your new device. Open the gallery and make sure that all albums and photos are displayed correctly, without broken files.
Check your contact list and call a few important people to make sure that the numbers are saved correctly. Pay special attention to banking applications and two-factor authentication - they often have to be reconfigured manually for security reasons.
If all the data is in place, you can start wiping the old device. Before selling or recycling, be sure to perform a hard reset (Factory Reset), first removing the memory card and SIM card. This ensures that your personal information does not fall into the wrong hands.

Frequently asked questions (FAQ)
Is it possible to transfer data if on one Android phone, and on friend iPhone?
The application Copy My Data supports cross-platform operation. You can transfer contacts, calendar, and media files from Android to iOS and vice versa, as long as both devices are connected to the same Wi-Fi network. However, transferring applications and their data is not possible due to differences in operating system architectures.
How long does it take to transfer 10 GB of data?
The time depends on the speed of your router. When using Wi-Fi 5 (AC), transferring 10 GB may take 15 to 30 minutes. On older routers with only 2.4 GHz support, this process can take an hour or more.
Do you need the Internet to use Copy My Data?
Global Internet access is not required. The application uses local Wi-Fi network for direct connection between devices. However, to initially download the application itself from the Play Market store, of course, you need the Internet.
What to do if only contacts were transferred, but no photos?
Check the application permissions. In Android settings, go to the "Applications" section, find Copy My Data and make sure it is granted access to "Storage" or "Files and Media". Without this right, the app will not be able to read photos.
Will information be deleted from the old phone after the transfer?
No, the copying process does not delete data from the source. All files will remain unchanged on the old smartphone until you decide to delete them or reset the settings.
