Buying a new smartphone is always an exciting event, which, however, is often overshadowed by the frightening prospect of transferring all the accumulated digital life. We are used to the fact that everything is set up perfectly on an old device: the necessary applications are in their place, passwords are saved in the browser, and the gallery contains thousands of memories.
Fortunately, the ecosystem Android has made a huge step forward in recent years in matters of data migration. You no longer need to manually rewrite your contacts or look for a USB cable to connect to your computer. Modern methods allow you to clone the contents of an old phone to a new one literally in one evening.
In this article we will analyze in detail all the available methods of transferring information, from cloud services to direct cable connection. You will learn what nuances exist when moving between different brands and how not to lose important files during the setup process.
Preparing devices before starting migration
Before launching any migration tool, it is critical to complete a number of preparatory steps. Ignoring this step may result in the process freezing or losing some data. First, make sure that both smartphones are charged at least 60-70%, and it is best to connect them to power sources for the duration of the entire procedure.
Secondly, check the availability of free space on the receiving device. The amount of data transferred should not exceed the available space on the new phone. If you plan to transfer heavy video archives or games, free up space in advance or insert a memory card MicroSD.
⚠️ Attention: If applications from unofficial sources (APK files) are installed on your old phone, they may not be transferred automatically through standard utilities. Make backup copies of them separately or download the installers again.
It is also recommended to clear the cache on the old device so as not to copy “junk” files that take up space but do not carry any useful load. This will speed up the transfer process and save time on the initial indexing of files on the new gadget.
☑️ Checklist for preparing for the transfer
Don't forget to update the operating system on both devices to the latest available version. Developers often fix errors in data transfer protocols in the latest security patches. Go to Settings → System → System update and check for updates.
Using a Google account for cloud recovery
The most universal and reliable method that works on any device with OS Android regardless of the manufacturer, this is synchronization via a Google account. This method is ideal for transferring contacts, system settings, call history and a list of installed applications.
The process begins on the old phone. You need to go to settings and activate full synchronization. The system will create a blind snapshot of your data and upload it to the corporation's servers. This takes time depending on the speed of the Internet connection and the amount of information.
On your new device, when you turn it on for the first time, you will be asked to enter your username and password for your Google account. Once authorization is successful, the system will offer to restore data from the latest backup. You will see the date the backup was created and a list of what will be restored.
Use a high-speed Wi-Fi network to download the backup. mobile data may be unstable and limited, which will interrupt the download of large amounts of data.
It is worth noting that this method primarily restores settings and application lists. The app files themselves (cache, logins inside games, offline maps) are often not saved if the developer has not provided for cloud saving of progress within the application itself.
| Data type | Transferred via Google | Requires manual action |
|---|---|---|
| Contact | Yes (automatically) | No |
| Photos and videos | Yes (via Google Photos) | Checking compression quality |
| SMS and call logs | Yes | No |
| Wi-Fi passwords | Yes | No |
| Data inside games | Partially (depending on games) | Login to your game account |
For users who store all media files in original quality, it is important to remember storage limits Google Drive. A free plan of 15 GB may not be enough for a full backup of the gallery, so some of the data will have to be transferred in other ways.
Branded utilities of smartphone manufacturers
Large vendors, such as Samsung, Xiaomi, Huawei and others, have developed their own powerful tools for migration. These apps often work faster than standard Android tools, as they use optimized transmission protocols via Wi-Fi Direct or cable.
For example, owners Samsung use the application Smart Switch, which allows you to transfer almost everything, including the location of icons on the desktop and alarm clocks. U Xiaomi is an analogue Mi Mover, and U Huawei — Phone Clone. These utilities are usually preinstalled on new devices.
The main advantage of proprietary solutions is the ability to transfer data even from devices of other brands. You can install a client application on an old phone (for example, an iPhone or an old Android of a different brand) and transfer data to a new flagship of a specific manufacturer.
The process usually looks like this: you launch the application on both phones, select the role (sender or recipient), scan QR code for pairing and select categories of data to transfer. Copying speed can reach 30-40 MB/s, which is much faster than cloud methods.
⚠️ Attention: When using proprietary utilities, do not minimize the application or lock the smartphone screen. Some models are aggressive in saving power and can drop the connection in the background.
It is important to consider that some system settings specific to the old manufacturer's shell (for example, themes MIUI or OneUI previous versions) may not display correctly on the new system. In this case, the system will prompt you to reset them to default values.
Direct connection via USB-C cable
With the release of Android 12 and later, the process of setting up a new phone has become even easier thanks to support for direct cable connection. If you have an adapter USB-C to USB-C (or a cable with different types of connectors), you can physically connect two phones.
This method is considered the most stable and fastest. It does not depend on the quality of the Wi-Fi signal and does not require registration in cloud services to transfer basic data. When connecting the cables, the system will automatically recognize the second device and offer to launch the transfer wizard.
Unlike wireless methods, a cable connection guarantees data integrity even with large amounts of information (hundreds of gigabytes). The risk of breaking the connection here is minimal unless you accidentally pull the wires.
What to do if the phone does not see the cable?
Make sure that the cable supports data transfer, and not just charging. Try a different USB port or restart both devices. Sometimes enabling USB debugging mode in the developer menu helps.
After physically connecting, follow the instructions on the screen. You will need to trust the device on both screens. Next, the process proceeds automatically: applications, photos, contacts and settings are copied.
However, this method has a limitation: you will need an appropriate cable or adapter, which is not always included with new smartphones (the environmental policies of many brands exclude them from the box). You will have to buy an additional accessory separately or find it at home.
Transferring data via an SD card or computer
If wireless methods for some reason do not work or raise security doubts, you can use the “old school” - an intermediate medium. This method requires more manual steps, but gives full control over which files will be moved.
First, remove the memory card MicroSD from the old phone (if there is one) and insert it into the new one. The files will become available instantly. If there is no card slot, use the computer as an intermediary: connect the old phone, copy the folders DCIM, Download, Documents to the PC hard drive.
Then connect the new smartphone and transfer the data from the computer to it. This method is ideal for media files, documents and music. However, it is not suitable for transferring installed applications, system settings and passwords.
⚠️ Attention: When copying via a computer, carefully check the folder structure. Some applications store data in specific directories inside the folder
Android/data, which may be hidden by default.
It is also worth mentioning the file system format. If your SD card is formatted as the old phone's internal storage (Adoptable Storage), the new phone may not be able to read it without formatting, resulting in data loss. In this case, use the card reader on your PC to extract the files.
Using a PC or SD card is the best way to transfer heavy media files (4K videos, RAW photos) when cloud storage is full and wireless transfer is too slow.
After copying is complete, be sure to safely remove the drive. On Android, this is done through the notification shade: click on the SD card icon and select “Eject” before physically removing it from the slot.
Transferring instant messengers and banking applications
Instant messengers such as WhatsApp, Telegram and Viber, as well as banking applications. These apps store data in encrypted form and often require separate actions to transfer correspondence history.
For WhatsApp standard transfer via Google Account works well, but only if a fresh backup was created on the old phone in the settings of the messenger itself. When installing the application on a new phone, it will automatically detect the backup and offer to restore chats.
The situation is simpler: the entire correspondence history is stored on the messenger servers. You just need to enter your phone number and verification code, and all chats (except secret ones) will appear automatically. Secret chats are tied to the device and are not transferred. Telegram simpler: the entire correspondence history is stored on the messenger servers. You just need to enter your phone number and verification code, and all chats (except secret ones) will appear automatically. Secret chats are device-specific and do not transfer.
Banking applications require a special approach for security reasons. When transferring to a new device, you will almost always have to go through the verification procedure again: enter your login, password, code from SMS, and sometimes confirm your entry via a call to the bank or biometrics.
Before resetting your old phone, be sure to exit all banking applications and unlink the device in the bank's security settings. This will prevent your account from being blocked due to suspicious activity.
Some banking applications use the "Transfer Keys" function or scanning a QR code from an old device for quick authorization on a new one. Look for this option in the application security settings before deleting it from your old smartphone.
Frequently asked questions and problem solving
Why do some applications not open after transfer?
This may be due to incompatibility of Android versions or the lack of necessary Google services on the new device (relevant for some Chinese models). Try updating the application through the Play Market or reinstalling it manually.
Is it possible to interrupt the data transfer process?
It is highly not recommended to interrupt the process, especially when using a cable connection or proprietary utilities. This may result in file corruption or software failure ("brick") of the receiving device. If the transfer is stuck, it is better to restart both phones and start again.
Will passwords from Wi-Fi networks be transferred?
Yes, if you use a Google account or a proprietary utility from the same manufacturer. Passwords for saved Wi-Fi networks are synced along with other system settings, and your new phone will automatically connect to familiar networks.
What to do if your new phone is low on memory?
During the setup process, the Transfer Wizard usually shows the total data size. If there is not enough space, the system will offer to select only the most important categories (for example, only contacts and photos, without videos and applications). You can also transfer the database first and upload media files later via the cloud.
Do you need to format your old phone before selling it?
Absolutely! Once you have verified that all data has been successfully transferred and is working on the new device, perform a full factory reset (Settings → System → Reset settings) on your old phone. This will delete all your personal data and accounts.
