In this article, we will take a detailed look at every step, from unpacking to fine-tuning the MIUI interface. You will learn how to secure your data, disable intrusive advertising and make the phone work as efficiently as possible from the first minutes of use.
⚠️ Warning: Before you start any manipulation of system settings, make sure that the battery is at least 50%, to avoid suddenly shutting down the device at a critical moment.
Primary activation and installation SIM-map
The first step in getting to know the device is to physically fit the communication modules correctly. 9A It is equipped with a separate slot for a memory card, which allows you not to sacrifice one of the SIM-mapping.
Use a special paper clip that comes with the kit to extract the tray. Notice the circuit that is struck on the tray itself: SIM cards are placed in certain positions, and the microSD card has its own unique place.
Once the device is turned on, the system will prompt you to select an interface language and connect to the wireless network, a critical step, since without the Internet, you will not be able to check for security updates or activate an account.
- 📱 Remove the tray with a paper clip, taking care not to damage the mechanism.
- 📡 Install. SIM-cards in the correct position, following the contours of the tray.
- 💾 If necessary, insert the microSD memory card before the snap of the locker.
- 🔌 Put the tray back in the case to the end.
Don't rush to insert the tray back if you see dust or villi inside the compartment. gently blow the hole or use a soft brush, as foreign particles can disrupt contact and cause periodic network losses.
Setting up a Mi and Google account
Xiaomi’s ecosystem is based on two main profiles: a global Google account and its own Mi Account, the first one necessary for the Play Market app store, synchronization of contacts and the use of standard search services.
The second profile provides access to the Xiaomi Cloud cloud storage, device search features and exclusive design themes, and Mi Account creation is especially important for users who plan to purchase other equipment of the brand in the future.
When registering, carefully enter data, especially the phone number and backup email. In the case of locking or losing your password, this data will allow you to restore access to the device, which is a standard security procedure.
⚠️ Warning: Never ignore two-factor authorization when creating accounts, this will protect your personal photos and documents even when your password is hacked.
The login process can take several minutes, especially if security check is enabled, and the system can request confirmation via SMS or an authenticator app if you have previously used this account on other gadgets.
System update and security
Once turned on, the smartphone may not work on the latest version of the operating system, and manufacturers regularly release patches that eliminate vulnerabilities and improve the stability of Android and the MIUI shell.
To check for updates, you need to go to the settings menu. The path usually looks standard, but different versions of the firmware may have slightly different layouts of elements.
Settings → The phone. → Version. MIUIClick on the system logo or update check button. If a new version is available, download and install it. This process can take anywhere from 10 to 30 minutes, during which time the phone will restart.
☑️ Checklist for updates
It is important to note that an update to a new major version of Android (for example, from 10 to 11) may not come immediately, but only a few months after the official release for a particular model.
Optimizing the interface and removing advertising
One of the most talked-about features of Xiaomi’s budget smartphones is the availability of ad integrations in system applications. Fortunately, most of them can be manually disabled, making it much more enjoyable to use the gadget.
Banner ads often appear in standard apps like Explorer, Music, or Security, and you’ll need to visit several sections in your privacy settings to disable them.
- 🚫 Go to Settings. → Passwords and security → Access to personal data and disable the msa service.
- 📢 In the "Security" application, open the settings and find the "Receive recommendations" item by deaktiviring it.
- 🎵 In the standard player and video player, you should also disable the option "Show ads" in the settings of each application.
Once the msa service is disabled, the system will ask you to wait 10 seconds before confirming an action, and this is done specifically so that the user does not accidentally turn off an important service, although in this case we are doing this consciously.
Also worth paying attention to the topic of design. A standard theme may contain advertising widgets on the desktop. on the classic theme "Classic" or "Default" often solves the problem with unnecessary interface elements.
Basic performance settings
The Redmi 9A is built on the MediaTek Helio G25 processor, which is an entry-level processor, and the animations and backgrounds must be configured correctly to ensure smooth operation.
In the Developer menu, which you need to activate with a few clicks on the build number, you can find the animation scale parameters, and reducing these values visually speeds up the interface response.
| Parameter | Standard value | Recommended value | The effect |
|---|---|---|---|
| Window animation | 1x | 0.5x | Accelerating the opening of applications |
| Animation of transitions | 1x | 0.5x | Quick switching between screens |
| Duration of animation | 1x | 0.5x | A general sense of speed |
| Background processes | No restrictions. | No more than 2-3. | Savings in RAM |
You should not set minimum values or turn off animations completely, as this can lead to twitchy images and discomfort when perceiving the interface. The value of 0.5x is the “middle ground”.
In addition, in the battery settings, it is recommended to turn on the Battery or Balanced mode, avoiding the No Limits mode, which can cause the processor to overheat during active tasks.
Memory and storage
Budget models are often equipped with a small amount of internal memory (32 or 64 GB), which is quickly filled with system files and application cache. Proper storage management is the key to a long life of the smartphone.
MIUI has a built-in cleaning tool, but it is not always effective, and it is recommended to manually transfer heavy media files (photos, videos, music) to a memory card or cloud storage.
Applications that support the work with SD-And you can, in the settings of each application, change the way you save data. This is true for navigators, voice recorders and some instant messengers.
- 🗑️ Clean the cache of messengers (Telegram, WhatsApp) regularly, as they can take up gigabytes of space.
- ☁️ Set up sync photos with Google Photos in "Save space" mode to automatically delete copies from the device.
- 📦 Remove unused apps immediately after installation so they don’t accumulate background debris.
Remember that the speed of the memory card affects the performance of the phone. Using cheap cards of low class can lead to brakes when running applications installed on an external medium.
⚠️ Attention: do not fill the phone's internal memory to the fullest. For stable operation of the system, the minimum must always be free. 10-15% total.
