Changing a mobile device often causes users to feel mixed feelings: on the one hand, the joy of owning a new gadget like the Redmi 9 Pro, and on the other – the fear of losing important files or getting confused in settings. The process of migrating from one brand’s Android smartphone to another brand’s device has become much easier in recent years, but still requires a careful approach. Samsung owners are accustomed to the One UI shell and specific services of the Corporation, so switching to MIUI can seem difficult without the right preparation.
With modern tools, you can copy almost all your digital baggage in minutes if you follow a proven algorithm. The main challenge is not just transferring photos, but also correctly working accounts, banking applications and instant messengers. In this article, we will discuss all the stages of the transition in detail, so that your new Xiaomi immediately becomes a full-fledged working tool.
Before starting the procedure, make sure that both devices are charged at least 60%, as active data transfer can significantly consume energy. It is also recommended to check the availability of free space on the target device to avoid errors in the copying process. Proper preparation will eliminate 90% of the potential problems that beginners face when first setting up.
The first and most critical step is to prepare the original Samsung device and the target Redmi 9 Pro. Many users underestimate this step, relying on automatic systems, however, pre-cleaning and updating the software can save you from a lot of errors.
Make sure that both devices have Wi-Fi and Bluetooth enabled, as these modules are used to create a local connection. Samsung recommends upgrading the system software to the latest available version through the settings menu, which ensures that data protocols are compatible and drivers are up to date.
On the new Redmi 9 Pro, when you first turn on, you will be asked to select a language and connect to the network. Don't rush to complete the initial setup if you plan to use specialized migration tools. Some MIUI features will only be activated after the master setup is complete, so you'd better walk to your desktop.
It is also important to check the Android versions on both devices. Although modern tools are cross-platform, a significant difference in the operating system versions (for example, Android 8 vs. Android 10) can lead to some system settings not being ported correctly, in which case you will have to manually configure them.
⚠️ Warning: Before any data transfer operations are initiated, make sure to back up important files on external media or in the cloud. Despite the reliability of modern algorithms, the risk of accidental data loss when changing ecosystems always exists.
☑️ Preparing devices for migration
There are several proven ways to transfer information, each with its own advantages depending on the amount of data and user preferences. The most popular and effective method for linking Samsung - Xiaomi is using the proprietary Mi Mover application. This tool is designed specifically for migration to MIUI devices and supports the transfer of contacts, messages, photos, music, videos, installed applications and even some system settings.
The alternative is to use Google cloud services, because both operating systems are Android-based, synchronization through a Google account allows you to recover contacts, calendar events, notes and installed app lists, but this method requires a stable and fast Internet connection, and does not always carry data within applications (for example, progress in games or correspondence in messengers).
For users who prefer full control, a manual method is available via computer.You can copy files from Samsung to a PC and then flip them to Redmi 9 Pro via a PC. USB-This method is ideal for transferring large volumes of media files (video to video). 4K, RAW-photos) when wireless transmission may take several hours.
- 📱 Mi Mover: Xiaomi’s native app for fast wireless data transfer between Android devices.
- ☁️ Google Sync: Automatic synchronization of contacts, calendar and list of applications through your Google account.
- 💻 PC Transfer: Manually copying files through a computer, ideal for large amounts of data.
Why is Mi Mover better than Google Sync?
The Mi Mover app is a regular tool for Xiaomi and Redmi devices, including the Redmi 9 Pro model. It is often preinstalled on new smartphones, but if it is not available, the program can be downloaded for free from the Google Play Store or GetApps. Samsung device will also need to install a similar application that is available in the official app store.
The process starts with opening the app on both devices. On Redmi 9 Pro, you need to select the Receiver role, after which the smartphone will create a Wi-Fi hotspot. On Samsung, you select the Sender role, and you need to find the name of the new device in the list of available networks. The password for the connection is usually displayed on the screen of the receiving gadget.
Once the connection is established, the interface will suggest selecting data categories to transfer, you can choose all at once or specify specific file types, such as only Gallery and Contacts. The transfer speed depends on the amount of data and the quality of the wireless connection, but it is usually much higher than over the mobile Internet.
💡
If the transfer process is stuck at a certain percentage, don't panic. Leave the phones alone for 10-15 minutes. Often the system just processes large files or a lot of small images, and an interruption can disrupt the integrity of the data.
One of the main problems in the transition from Samsung to Xiaomi is the migration of user data within applications, especially messengers. WhatsApp, Telegram, Viber and banking applications have their own mechanisms for protecting and storing data that are not always copied by standard migration tools.
In the case of WhatsApp on Samsung, you need to go to chat settings and back up to Google Drive. When you first start WhatsApp on Redmi 9 Pro using the same phone number and Google account, the app will offer to restore your correspondence history. Without this step, you will get a “clean” messenger without the old dialogues.
Banking applications and services with two-factor authentication (2FA) This is a security measure that you can't get around, make sure you have access to the phone number that you're coming to. SMS-codes, or a code generator that can be transferred.
⚠️ Note: Bank applications (Sberbank, Tinkoff, Alpha, etc.) may require re-binding the device. SIM-The card with the number tied to the bank is active and is located in or near the phone for reception. SMS-proof.
Once the main data port is complete, a series of steps must be taken to optimize the Redmi 9 Pro. MIUI has its own power management features that can aggressively close down background applications, including instant messengers. To ensure notifications arrive on time, you need to manually configure permissions for key applications.
Go to the battery settings and find a list of apps. For WhatsApp, Telegram, email and other important services, set the “No Limits” mode to prevent the system from “sedating” the application and losing push notifications. It is also useful to disable automatic memory cleaning in the background for selected programs.
Check your contacts sync. Sometimes, when you move, contacts can stick in your phone's memory instead of your Google account. Open the Contacts app, go to settings, and make sure you check the sync box with your Google account, which will keep your phonebook safe the next time you change device.
💡
Setting up notifications and power saving in MIUI is a critical step without which you can stop receiving messages in instant messengers.
The table below compares the basic data transfer techniques so you can choose the most suitable one for your situation.
| Method | Speed. | What's transferable | Difficulty |
|---|---|---|---|
| Mi Mover | Tall. | Everything (photos, apps, settings) | Low. |
| Google Sync | Medium | Contacts, applications, calendar | Low. |
| PC + USB | Depends on the cable. | Files (photos, videos, documents) | Medium |
| Bluetooth | Very low. | Separate files | Low. |
The final step is to check the integrity of the data, go through the gallery, the contact list and the apps installed, make sure the photos open and the phone numbers are true. If you've used Mi Mover, check if the apps have fallen into place on your desktop.
Remember to delete data from the old Samsung only after you have fully verified the performance of the new Redmi 9 Pro within a couple of days, which is insurance in case any important file gets lost during the migration.
