Moving to a new smartphone is always an exciting process, especially when you change the ecosystem, for example, from Samsung to Xiaomi. Poco X3 Pro owners often face the need to quickly and easily transfer all their contacts, photos, music and app settings. Fortunately, modern technology makes it as simple as possible using built-in tools or specialized software.
In this article, we will take a look at all the available data migration methods so that you can start using a new device immediately after unpacking, and we will look at both official utilities from manufacturers and proven third-party solutions that ensure the safety of your digital information.
No matter how much media you have, or how complex your folders are, the right sequence of actions will help you avoid chaos. Let's get both devices ready to sync.
Preparation of devices before the migration
Before you start any copying process, make sure both smartphones are ready to go.This is a basic step that is often ignored, leading to a data interruption midway through the process. Make sure that Samsung and Poco X3 Pro have at least 60 percent battery charge, and ideally connect both devices to a power source.
Also check for free space on your new phone. The internal storage capacity of the Poco X3 Pro should be greater than the amount of data you plan to transfer from Samsung. If you use cloud services, make sure the Wi-Fi connection is stable and has no traffic restrictions.
The important thing is to unlock both screens and install all system updates available at the time of the transfer, which minimizes the risk of software version conflicts.
- 🔋 Charge both smartphones to a minimum of 60-70% Or connect to the chargers.
- 📶 Connect both phones to the same Wi-Fi network to speed up transfers without using mobile traffic.
- 🔓 Unlock screens and allow any requests for access to data that may appear.
- 📂 Make room for Poco X3 Pro by removing unnecessary system files or temporary applications.
⚠️ Note: Do not interrupt the data transfer process or switch to other heavy applications during migration to avoid database synchronization errors.
After these simple steps are done, you can go directly to the transfer method, and there are several ways to solve the problem, each of which has its own advantages depending on the amount of information.
Using the Mi Mover app for fast transfer
The most efficient and native way to migrate data is to use the Mi Mover app, which is designed specifically for migrating to Xiaomi and Poco devices, providing high speed and support for a wide range of file formats. You don't have to look for complex settings, just download the app to an old phone.
On the Poco X3 Pro, the app is already built in and is in the Tools folder. On Samsung, it must be downloaded from the Google Play Store. After installing on both devices, run the program and select the corresponding roles: Sender on the old phone and Receiver on the new one.
Create an access point via a new phone or scan QR-The system will then ask you to choose the types of data to copy, and the algorithm is optimized to preserve the folder structure and file metadata.
☑️ Preparation for the Mi Mover
The process can take anywhere from 15 minutes to several hours depending on the amount of data, at which time the screens of the devices may go out, but the application will continue to work in the background if it is not interrupted by the energy saving system.
- 📲 Install Mi Mover on Samsung from the official app store.
- 📡 Create a connection through QR-code or manually enter a Wi-Fi Direct password.
- 🗂 Select data categories: Contacts, messages, images, videos, music and apps.
- ⏳ Wait until the process is over and check the integrity of the files on the new device.
⚠️ Note: When ported via Mi Mover, some Samsung specific settings (such as Good Lock or Samsung Pay) won’t work on Poco due to shell differences MIUI One UI.
This is the most reliable way for those who want to get a clone of their old phone on a new platform with minimal effort.
Alternative methods: Google Account and Cloud Services
If you don’t want to use third-party apps or don’t have the ability to install them on your old phone, you can rely on Google’s ecosystem.It’s a standard method that automatically syncs key data when you first turn on any Android smartphone, including the Poco X3 Pro.
To start, make sure Samsung is fully synced. Go to your Google account settings and check that Chrome contacts, calendar, notes and data are tagged for sync. Photos and videos are best done through Google Photos by enabling Autoboot and Sync.
When you turn on the Poco X3 Pro, just type in the same email address and password. The system will suggest recovering data from the backup. The good thing about this method is that it is universal and does not depend on the brand of the sender device.
💡
Use Google Photos in Storage saver mode to save space in the cloud when you transfer a large number of photos and videos.
However, this method has limitations: it will not transfer the applications themselves (only their list for manual installation) and will not copy files from internal memory that are not related to system data, and there may be problems with the history of WhatsApp, if you do not make a separate backup in Google Drive.
- ☁️ Complete full sync on Samsung via the Accounts and Archiving menu».
- 📸 Check the download status in the Google Photos app before the “Done” icon appears».
- 📥 When you sign in to your Poco account, select the last available backup.
- 🔄 Wait for the background load of contacts and calendar events after the initial setup.
This option is ideal for those who appreciate minimalism and want to set up a new phone from scratch, installing only the most necessary.
Transfer of WhatsApp messages and messengers
WhatsApp’s messaging needs to be highlighted, as it stores history locally or in the cloud, but doesn’t sync it through a standard Google account as transparently as contacts. The best way to successfully migrate chats between Android devices of different brands is to use the built-in chat migration feature.
On Samsung, open WhatsApp, go to Settings → Chats → Backup Chats and create a fresh backup on Google Drive. Make sure you use the same Google account you will use on Poco X3 Pro.
When you first run WhatsApp on a new phone, the app will automatically detect a backup in the cloud and prompt you to restore it. It's critical to use the same phone number and the same Google account, otherwise it won't be possible to restore it.
What if WhatsApp doesn’t see a backup?
For other instant messengers, such as Telegram or Viber, the procedure is simpler: Telegram stores the entire history on the server, so it’s easy enough to enter a phone number. Viber requires you to create a local backup or use the “Viber Backup” feature via Google Drive, similar to WhatsApp.
- 💬 Backup WhatsApp on your old device before resetting or transferring.
- 🔢 Use the same phone number when registering on a new smartphone.
- 🌐 Make sure your internet connection speed is sufficient to download media files from the cloud.
- 📲 For Telegram, just log in to your account – the story will be downloaded automatically.
⚠️ Attention: Local WhatsApp backups (files.crypt12 etc.) will not be automatically found when changing your phone brand, use only the cloud method via Google Drive.
Comparison of data transfer methods
To make it easier for you to choose the right way, we have prepared a comparison table that will help you evaluate the pros and cons of each method depending on your priorities: speed, data volume or ease of customization.
Each method has its own peculiarities: for example, a cable connection (if you use a USB-C to USB-C adapter) can be faster than Wi-Fi, but requires accessories. Wireless methods are more convenient, but depend on the quality of the signal.
Choosing the right tool will save you time and nerves. Let's look at the basic comparison parameters.
| Parameter | Mi Mover | Google Account | Cable (USB-OTG) |
|---|---|---|---|
| Transmission speed | High (Wi-Fi Direct) | Medium (depending on the Internet) | Very high. |
| Data types | All (including system settings) | Contacts, photos, calendar | Files, photos, videos |
| Difficulty | Low. | Very low. | Medium (need cable) |
| Network dependency | No requirement (local area network) | It requires stable Wi-Fi. | Not required |
As you can see from the table, Mi Mover is the most balanced solution for switching to Xiaomi equipment, combining high speed and deep access to system data.
Problem Solving and Troubleshooting
Even when following instructions, there may be technical difficulties, and users often experience a 99 percent shutdown or some apps not opening after a transfer, which is normal, due to differences in the architecture of the processors or Android versions.
If the process is stalled, try restarting both phones and starting over again by selecting only data categories that have not been moved, and it is also worth turning off the power saving on both devices during the migration, as the system can kill the background transmission process.
In case of problems with the display of contacts, check where exactly they were saved. SIM-Map or Google account. Contacts SIM-The card can be imported with the loss of some information (for example, without email or additional numbers).
💡
If the app doesn’t work after the transfer, uninstall it and reinstall it from the Google Play Store – this will update compatible libraries for the new processor.
Sometimes manually configuring access rights for portable applications is required, especially for those that work with a file system or microphone. MIUI This is handled through the Permit Manager.
- 🔄 Restart both smartphones if data transfers are stuck for a long time.
- 🔋 Turn off energy saving during the migration process.
- 📞 Check the source of the contact retention (SIM or Google, in the absence of such.
- 🛡 Check the permissions for applications in Poco security settings.
A systematic approach to eliminating errors will ensure that migration is completed successfully in most cases.
