Modern smartphones store huge amounts of sensitive information, so the question of their physical safety becomes critical. If you become the owner of the popular Xiaomi Redmi 9, one of the first tasks should be to ensure the ability to remotely track it.
The MIUI operating system on Redmi 9 has powerful privacy protection tools, but many users buy a phone with basic settings already on without thinking that key security options can be deactivated by default. In this article, we’ll detail how to activate and properly configure your device search so that you always stay in charge of your smartphone.
The setup process does not require deep technical knowledge, but it requires careful input of account data. Accuracy of steps ensures that in an emergency the system will work like a clock. We will look at both the built-in tools of the Xiaomi ecosystem and standard Google services, which duplicate each other and increase the chances of success.
Preparation of Mi Account and synchronization
The foundation of the entire security system in Xiaomi devices is the Mi Account. Without registration and authorization in the profile, using cloud functions, including device search, is technically impossible. When you first set up Redmi 9, the system often suggests creating an account, but if you missed this step, it must be done manually through the settings menu.
Once you create an account, it's critical to make sure that you're synchronizing your data, which allows you to transfer your current geolocation coordinates to your company's servers, where you can access your information through your browser, open your settings, select the top item with your name, and check the status of your cloud services.
Pay attention to the following parameters that must be active for proper operation:
- 📍 Device Search – The Master Switch that Activates Tracking.
- 🔄 Synchronization – provides real-time location data transmission.
- 🔒 Blocking activation – prevents the phone from being used after being reset without the owner’s password.
It's important to understand that to function, the phone needs to have an active Internet connection, and if the device is stolen and an attacker immediately turns off data transmission or puts the smartphone in flight mode, it will be extremely difficult to track it, so a constant connection to the network is a must.
⚠️ Warning: Never give your Mi Account password to outsiders, even if they pose as support staff. Fraudsters may use access to your account to lock your device for ransom.
Checking your account status takes only a few minutes, but saves you from huge problems in the future. Make sure you remember your account password or it's stored in a safe place. If you lose your phone, that's the key to getting it back.
☑️ Account security check
Activation of geolocation and location services
Even if the search function is enabled in the account, the smartphone itself must have permission to use its coordinates. In Xiaomi Redmi 9, the GPS module is responsible for this, which must be activated in the system. Without accurate positioning, you will see only an approximate area of the device on the map, which will significantly complicate the search.
To enable geolocation, lower the notification curtain and find an arrow or compass icon. However, for full operation, it is recommended to go to the advanced settings. Go to Settings → Privacy → Permit Management → Permits and make sure that system services have access to the location.
The high-precision mode uses not only GPS satellites, but also Wi-Fi and cell tower data to better position indoors, especially in urban environments where satellite signals can be weakened by buildings.
There are several geolocation modes that affect battery consumption and accuracy:
- 🛰️ Only GPS — maximum accuracy in open areas, but slow operation indoors.
- 📡 The coordinates of the network are fast, but less accurate, works even without satellites.
- ⚡ High accuracy – combines all sources, the best choice for finding a device.
Users often wonder how much GPS on affects the Redmi 9’s autonomy. Current MIUI algorithms are optimized enough that in the background, positioning does not lead to a critical battery discharge. However, if you are in the bad signal zone, the phone can spend more energy trying to find satellites.
💡
To save charge in normal mode, use GPS only, but before potentially dangerous situations (travel, mass events) switch to High accuracy.
Setup of data transmission and Internet access
The key to finding a device is that it can log in to transmit its location. On Xiaomi Redmi 9, it requires the right setup of mobile internet and Wi-Fi. If the phone is locked with a password, it should still be able to connect to the network to send coordinates.
In your mobile network settings, make sure that data is on, check if background activity limits are set for system applications, and sometimes aggressive battery optimization can kill the process responsible for sending the geoposition, considering it inactive.
There's an important feature about MIUI: even if the mobile Internet is turned off, the smartphone can try to connect to a known Wi-Fi network to transmit data, but you shouldn't count on it. It's much more reliable if you have the option to transmit the last known location before the battery runs out.
Let’s look at the basic parameters that need to be checked in the “Data Transfer” section:
- 📶 Mobile Internet – must be constantly enabled.
- 🔄 Background transmission – Allowed for Google and Mi Cloud system services.
- 🔋 Energy savings should not limit the operation of geolocation services.
If you are traveling, make sure that data transfers are allowed in roaming, otherwise the phone will not be able to communicate its location abroad, even if you are traveling. SIM-It's an often overlooked nuance that can cost you devices on a trip.
What to do if the internet is off?
Google Find My Device Service
In addition to the MIUI shell, every certified Android phone, including the Redmi 9, has a Google service that is an independent tracking channel that is often more effective, especially if your Mi somehow account is blocked or forgotten, and requires a Google account that you enter when you first turn on.
To activate this feature, go to Settings → Google → Find a device. This should have a "Remote Search Allow" switch on. The principle of operation is similar to Mi Cloud: the phone periodically sends its coordinates to Google servers, and you can see them on the map through a browser or other device.
The advantage of Google is that it integrates deeply with the Android operating system. Even if the MIUI shell gets overloaded or freezes, the system layer of Google Services will continue to work, which creates an additional layer of reliability for your device.
Compare the capabilities of the two search engines in the table below:
| Function | Mi Cloud (Xiaomi) | Google Find My Device |
|---|---|---|
| Map accuracy | High (using their cards) | Very High (Google Maps) |
| Off-screen work | Yes. | Yes. |
| Deleted call | There is. | There is. |
| Erasure of data | Yes. | Yes. |
Using both services simultaneously does not create conflict; instead, it provides redundancy; if one server is unavailable or fails, the other can successfully handle the search task, so security experts recommend keeping both options on.
💡
Dual activation of search services (Mi Cloud and Google) significantly increases the chances of a device returning, creating a backup channel.
Remote control: locking and cleaning
The most painful part of losing your phone is the need to take remote action. When you see your Xiaomi Redmi 9 on a map, you have three main options: play the sound, lock the device, or erase all the data.
Play Sound makes your phone make a loud signal at maximum volume, even when it's silent, which is useful if you've just lost your phone in your apartment or office. However, if there is a suspicion of theft, turning on the sound is dangerous - it will give the location of the phone to thieves, and they can quickly extract the phone. SIM-map.
Locking the device allows you to display a message with a contact number to communicate with the finder, you can write a text like, "This phone is stolen, please return for a fee, number..." This sometimes works if the phone has reached an honest person. Remote lock also prevents access to your applications and photos.
The last thing you do is wipe it completely. It's a nuclear option. Once it's done, the phone goes back to factory settings. You lose all the photos and contacts (if you didn't sync), but the attacker gets a brick that you can't activate without your password (thanks to FRP reset protection), and you only need to use it if you realize you can't get your phone back.
⚠️ Warning: After the remote erasure command, the device's search function will stop working as the phone will be reset. Use this option only as a last resort when the hope of a physical return is lost.
It's important to act quickly and coolly. Panic is a bad counselor. Think through a plan in advance: first, try to communicate and track, then lock, and only at the very end, erase. Every step must be considered.
Actions in case of loss or theft of a smartphone
If trouble does happen and your Redmi 9 is gone, the algorithm should be clear. First of all, don't try to call the number of the lost phone - this can wake up thieves or confirm that the phone is active and being watched. Instead, use another device to log in immediately.
Go to i.mi.com or android.com/find from a friend's computer or phone. Enter your credentials. If your phone is online, you'll see it on a map. Take a location screenshot, it'll be useful to the police. If the phone is offline, the system will show the last known location and time it was online.
The following steps should be followed in strict sequence:
- 🚔 Contact the police – write a statement, specifying IMEI (It's on a box or a check).
- 🔒 Block it. SIM-Card – call the operator to prevent thieves from using your number to obtain codes from banks.
- 🔐 Change passwords – primarily from email, social networks and banking applications.
- 📡 Monitor movement – periodically check the card, the phone may appear on the network.
Never try to take the phone from a criminal if you've figured out their location. It's life-threatening. Give the coordinates to law enforcement. Also beware of phishing SMS that can come after a theft with the text "Your phone is found, click on the link." You can't go through these links - you will give the thieves your password from your account.
