Changing a mobile device almost always causes mixed feelings among users: joy from buying the latest gadget and anxiety due to the loss of files accumulated over the years. Fortunately, the ecosystem Android has long outgrown the stage of chaotic copying of files via a computer, offering many automated solutions. Modern methods make it possible to transfer terabytes of information while preserving the folder structure, Wi-Fi passwords, and even the location of icons on the desktop.
The data migration process has become so transparent that it is often called “seamless.” However, to avoid annoying mistakes such as losing unsynced photos or messages from instant messengers, you need to prepare both devices in advance. In this article, we will analyze in detail all the available methods - from cloud services to direct cable connection, so that you can choose the most suitable one for your situation.
Before taking active steps, make sure that both smartphones are charged at least 50-60%. The process of transferring large amounts of data, especially via Wi-Fi Direct or the cloud, consumes a significant amount of energy. Also check the availability of free space on the receiving device: it should exceed the amount of memory occupied on the old phone with a margin of 10-15%.
Device preparation and backup
Successful transfer of information begins long before turning on the special mode on the new phone. The first step should be a thorough review of the content on the old device. Remove unnecessary duplicate photos, clear your Downloads folder of installation files and cache, so you don't waste time transferring digital junk. This will speed up the process and save space.
A critical step is account synchronization Google. It is this that serves as the foundation for restoring most system settings. Go to Settings → Accounts → Google and make sure that the sliders next to the “Contacts”, “Calendar”, “Notes” and “Disk” items are active. Click the "Sync" button manually to make sure that the latest changes have been sent to the cloud.
⚠️ Attention: If you use third-party launchers or specific widgets, keep in mind that they may not be restored automatically on the new device if the manufacturer of the new smartphone uses a different one shell.
Messenger data deserves special attention. WhatsApp, Telegram i Viber store correspondence history locally or in their clouds, ignoring standard Google synchronization. Go to the settings of each application and force a backup of your chats. Without this step, you risk losing important correspondence during the first authorization on the new device.
☑️ Checklist for preparing for the transfer
Method one: Official restoration upon first setup
The most reliable and preferred migration method is to use the built-in setup wizard, which starts immediately after turning on the new smartphone out of the box. System Android offers to restore data from a cloud copy or directly from an old device upon first launch. This method ensures that system settings and passwords are transferred correctly.
When you turn on your new phone and select a language, the system will prompt you to connect to a Wi-Fi network. Immediately after this, the "Copy apps and data" screen will appear. Here you will be offered two options: restore from the cloud Google Drive or use a cable/wireless connection to your old phone. The choice depends on the speed of your Internet and the amount of data.
If you choose the option with a cable, you will need an adapter USB-C to USB-C or a standard cable if the connectors are the same. Connect both devices to each other. A request for permission to copy data will appear on the screen of your old phone - confirm it. The system will automatically analyze the contents and offer a list of what can be transferred: applications, SMS, call history and media files.
Use the original cables included in the package to connect the phones. Cheap third-party wires may not support data transfer, working only for charging.
The process can take from 15 minutes to several hours depending on the number of photos and videos. During transmission, screens may turn off to save power, but the connection cannot be interrupted. After the copy is completed, the system will prompt you to sign in to your Google account, and all applications will begin to download in the background automatically.
Recovery at first setup is the only method that guarantees the transfer of passwords from Wi-Fi networks and system settings without the need for manual configuration.
Method two: Branded utilities of manufacturers
Large vendors understand that standard Android tools are sometimes not enough to completely clone the specific settings of their shells. Therefore, brands such as Samsung, Xiaomi, Huawei and OnePlus are developing their own powerful migration tools. These utilities often work faster than standard ones and can even transfer the arrangement of icons on the desktop.
For devices Samsung the gold standard is the application Smart Switch. It is preinstalled on all modern gadgets of the brand. The application allows you to transfer data not only from Android to Android, but also from iOS. The process is intuitive: launch the application on both phones, select a role (sender/recipient), scan the QR code and start transferring.
Smartphone owners Xiaomi, Redmi and POCO should use the utility Mi Mover. It is similar to Smart Switch, but optimized for the MIUI and HyperOS shell. The peculiarity of Mi Mover is that it creates a temporary Wi-Fi access point between devices, providing high transfer speeds without consuming Internet traffic.
| Brand | Utility name | Features | iOS support |
|---|---|---|---|
| Samsung | Smart Switch | Full system cloning | Yes |
| Xiaomi / Redmi | Mi Mover | High speed via Wi-Fi | Limited |
| Huawei / Honor | Phone Clone | Work without the Internet | Yes |
| OnePlus / OPPO | Clone Phone | Move screen layout | Yes |
The main advantage of proprietary utilities over standard tools is the depth of transfer. They are often able to download even alarm settings, calendar settings, and specific control gestures that are lost when using pure Android. It is recommended to always check for the presence of such an application in the "Tools" section on your new smartphone.
Method three: Google Drive and cloud services
If you don’t have a cable or adapter on hand, or your old phone has already been sold/discarded, cloud storage comes to the rescue. Google Drive automatically backs up most data if this feature has been previously enabled. The free storage capacity is 15 GB, which may not be enough for a full backup of media files, but is quite enough for contacts and settings.
To create a full copy manually, open the application Settings → System → Backup. Here you will see the date of the last copy and can start creating a new one by clicking the "Start copying" button. This backup archive will include a list of installed applications, call history, SMS messages and device settings.
⚠️ Attention: High-quality photos and videos may not be included in the standard system backup if your Google Photos is full. Check the sync status in the Google Photos app before resetting your old phone.
When setting up a new device, simply select the "Restore from Cloud" option and specify the same Google account. The system will download a list of applications and offer to download them from the Play Market. Content, such as photos and documents, will be pulled from relevant services as needed or in the background.
What if 15 GB of space is not enough?
You can temporarily purchase additional Google One storage for one month. It's inexpensive and will allow you to create a full backup before moving to a new phone. After the transfer, the subscription can be cancelled.
Transferring contacts and calendar manually
Sometimes the user needs to transfer only the most important information - the phone book and calendar events, without touching heavy files. The easiest way to do this is to export contacts to a file format .vcf. Open the Contacts app, go to Settings and select Export Contacts. The file will be saved in the internal memory.
Received file contacts.vcf can be transmitted in any convenient way: via Bluetooth, instant messenger or email. On a new phone, just open this file, and the system will offer to import all entries into the phone book. This method is universal and works even between different operating systems.
For the calendar, the situation is similar, but here it is better to rely on account synchronization. Make sure that your Google account is checked in the calendar settings on your old device. All events created locally (without being linked to an account) can be exported through the web version of Google Calendar on your computer to a file .ics, and then imported on a new device.
When exporting contacts, choose the vCard (vcf) format, as it supports contact photos and additional fields, unlike legacy CSV files.
Frequent problems and ways to solve them
Despite the well-functioning processes, users often encounter difficulties. One of the most common problems is an authentication error or a connection being lost mid-process. If the transmission is interrupted, don't panic. Most modern utilities allow you to resume the process from where it stopped or restart it without losing the data already transferred.
Another common situation is that applications are installed, but there is no data inside them. This happens if the app developer has not allowed their data to be backed up to Google Cloud (for example, banking apps or some games). In such cases, you will have to transfer the data manually through the internal export functions of the application itself or re-authorize.
⚠️ Attention: For security reasons, banking applications never transfer their settings and login data. You will have to re-enter your login, password and link the device in each banking application separately.
If the new phone “sees” the old one, but the transfer speed is extremely low (kilobytes per second), try disabling the power saving mode on both devices. Also make sure you're not connected to a congested 2.4GHz Wi-Fi network if you're using the wireless method; It's better to use 5 GHz or cable.
If the process is stuck at the "Data Preparation" stage for more than 20 minutes, the safest option is to interrupt the operation by rebooting both devices and try connecting them with a cable instead of Wi-Fi.
Completing the migration and cleaning the old device
After the progress indicator has reached 100%, do not rush to reset old phone to factory settings. Spend a couple of days using your new device as normal. Check that all critical applications are working, that all photos are in the gallery, and that your contacts are working correctly.
Make sure that two-factor authentication (2FA) is working correctly. If you use apps like Google Authenticator, their codes may not have transferred automatically. In this case, use the code export function inside the authenticator application on the old phone and scan the QR code with the new one.
Only after you are completely confident in the functionality of the new gadget can you start cleaning the old one. Go to Settings → System → Reset settings and select "Delete all data". This action is irreversible, so double-check the presence of all files on the new device again. After the reset, the old phone will be ready for sale or transfer to another user.
Is it possible to transfer data if the old phone is broken and does not turn on?
If the screen does not work, but the phone turns on and makes sounds, you can try connecting a USB mouse to it via OTG adapter to unlock it and allow data access for the computer. If the phone board is dead, you can only restore data from previously created Google cloud copies or backups on your computer.
Are passwords from sites saved in the browser transferred?
Yes, if you used the Google Chrome browser and were logged in to your account with synchronization enabled. When you log into the same account on a new phone, all saved passwords and browsing history will be automatically downloaded from the cloud.
What to do with the SD card when changing phone?
You can physically rearrange the card, but often the new system encrypts the card for a specific device. When installed in a new phone, the system may prompt you to format the card, which will delete all data. It is best to copy the files from the card to your computer, and then transfer them to the new phone.
How long does it take to transfer 100 GB of data?
When using a quality USB-C to USB-C cable, the process takes approximately 20-40 minutes. When transferring via Wi-Fi Direct, the time may increase to 1.5-2 hours depending on the speed of the wireless module and interference on the air.
Do you need to update the software before transferring data?
It is advisable to update both devices to the latest available version of Android. This minimizes the risk of database version conflicts and ensures support for the latest transfer protocols, which makes the process more stable and faster.
