Changing your mobile device's identifier isn't just a matter of aesthetics; it's an important step in securing your home network. When you connect your smartphone to a router or share your internet connection, the administrator's client list often displays a default manufacturer name, such as SM-G991B or XIAOMI 12. This can cause confusion, especially if you have multiple devices from the same manufacturer in your home and can't figure out which device is consuming bandwidth.
Changing this setting affects how your device is seen by other users when searching for Bluetooth devices or attempting to connect to your access point. The default names assigned by the manufacturer don't provide any useful information to the network owner. Furthermore, a unique name will help you quickly identify your phone in the router's list of connected clients, making it easier to control unauthorized access.
In this article, we'll take a detailed look at all the available methods for changing your username on the Android operating system. You'll learn where the necessary settings are hidden in different versions of the operating system, how this affects your online visibility, and what limitations exist. We'll also touch on security and explain why it's best to avoid using personal information as your online name.
Why do I need to change the device name on the network?
The main reason for changing the default identifier is security and anonymityThe factory model name often contains precise information about the manufacturer and series of the device. An attacker who has access to your WiFi network or is nearby in Bluetooth search mode can use this information to exploit vulnerabilities specific to a particular smartphone model.
The second important aspect is ease of administrationIf you manage a home network that includes laptops, tablets, TVs, and phones belonging to different family members, unique names will help you instantly identify who's using the channel. Instead of ten devices named "Android Phone," you'll see "Phone_Dad," "Tablet_Kids," and "Work_Laptop."
⚠️ Attention: Don't use your full address, phone number, or last name as your device name. This is personal information that is broadcast and can be accessed by any device within WiFi or Bluetooth range.
It's also worth considering the psychological factor and simple organization. It's more pleasant to see clear names of available devices that you've come up with yourself. This is especially true in offices or coworking spaces, where many devices may be on the same network. Proper networking identification Helps avoid errors when sending files via Bluetooth or connecting to a printer.
Where to find name settings in Android
The location of the settings responsible for the device name can vary significantly depending on the operating system version and the manufacturer's customization. In "stock" Android, such as that found on Google Pixel or Motorola smartphones, the path is usually very logical and hidden within the general system settings. You'll need to navigate to the section Settings → System → About phone → Device name.
For owners of devices with a shell One UI from Samsung or MIUI For Xiaomi devices, you'll have to look for this option in a slightly different place, as manufacturers often move it to the "General Settings" or "About Phone" menu at the very top of the list. It's important to understand that changing the name here affects how the phone appears when connected via Bluetooth and how it appears in some Google system services.
However, it is worth noting a critical point: changing the name in the "About phone" section not always Changes the name displayed on the WiFi router when connecting to the internet. A separate parameter is often used for WiFi connections, especially when using access point mode. In modern versions of Android (starting with version 10), the system strives to standardize the name, but older routers may still display the factory model ID.
☑️ Check before changing
Changing the name of a WiFi hotspot
If you want to change the name your laptop or other phone sees when you share your internet, you'll need to configure your access point settings. This creates a new WiFi network, and its name (SSID) is configured separately from the smartphone's name. To do this, go to Settings → Connections → Mobile hotspot & tethering.
In the menu that opens, find "Access Point Settings" or "Network Name." Here you can enter any name you like, using Latin characters, numbers, and some special characters. After saving the changes, your phone will broadcast the WiFi signal under the new name, and everyone around you will need to search for the network with this name to connect.
| Parameter | Standard value | Recommended value | Impact on the network |
|---|---|---|---|
| SSID (Network Name) | AndroidAP or Model | Unique_Hotspot_Name | Visibility for clients |
| Frequency range | 2.4 GHz | 5 GHz (if supported) | Speed and radius |
| Security protocol | WPA2-Personal | WPA3 (if available) | Encryption level |
| Hidden network | No | Yes (for hiding) | Visibility in the list |
They'll have to search for your network again using the new name and enter the password. This is a good way to "kick out" intruders if you suspect someone knows your password but forgot to change the network name to something unique.
Why might the name not change immediately?
Sometimes the operating system caches old network IDs. If, after renaming, the router or other devices continue to display the old name, try a full reset of network settings or rebooting the router your phone is connected to.
Differences in interfaces between different manufacturers
The Android ecosystem is fragmented, and each manufacturer makes its own changes to the interface. On smartphones Samsung The desired option is often located at the very top of the settings menu, just below the search bar, in the "General" section. Clicking it takes you to a menu where you can edit the device name used for Bluetooth and Smart View.
Devices Xiaomi (Redmi, POCO) With MIUI or HyperOS, this feature is hidden in the "About phone" section. There, find the "Device name" line and tap it to edit it. It's worth noting that in MIUI, this name is also used for display in Mi Share and when connected to a computer via USB (file transfer mode).
⚠️ Attention: The interfaces are being updated. If you don't find the options listed, use the settings search by entering "Name" or "Device Name." This is the fastest way to find the option you need in the confusing menu of the new firmware version.
On Huawei and Honor smartphones, the situation is similar to Samsung, but the menu may be called "System." On budget models with a stripped-down version of Android (Go Edition), the ability to change the name may be limited or completely absent from the user interface, requiring deeper intervention.
Technical limitations and symbols
When choosing a new name for WiFi or Bluetooth, consider the technical limitations of the protocols. While modern systems allow emoji and spaces, older hardware or specific operating systems (such as Windows XP or older versions of Linux) may display such characters incorrectly, replacing them with question marks or squares.
It is recommended to adhere to the following rules when forming a name:
- 🔤 Use only Latin letters (A-Z) and numbers (0-9) for maximum compatibility.
- 🚫 Avoid special characters like
/,\,",:, since they can be perceived by the system as service commands. - 📏 Keep the name length to 32 characters. Long names may be truncated in older router interfaces.
It's also worth knowing that some carriers or corporate security policies may impose a specific prefix on device names connecting to their WiFi. In such cases, changing the name completely won't be possible—the system will automatically revert to the default value each time you reconnect.
Visibility Problems and Their Solutions
Sometimes users encounter a situation where the name is changed in the phone settings, but the old name is displayed in the router or on the computer. This happens due to the mechanism DHCP-lease (IP address leases). The router remembers the device by its MAC address and assigned name, and the cache may not be updated immediately.
To force an update of information, you must perform the following steps:
- 🔄 Restart your router and smartphone simultaneously to reset network sessions.
- 📡 In the WiFi settings on your phone, select "Forget network" and reconnect.
- 🗑️ In the router's admin panel, find the list of clients and delete the old device entry manually.
Another reason could be the use of the "MAC Address Randomization" feature that appeared in Android 10. This feature Privacy Generates a random address for each new network, which can cause the router to perceive your phone as a new device with a default name. Disabling this feature for your home network will resolve the name persistence issue.
Impact on security and privacy
The device hostname is broadcast to the local network and can be seen by other users. If you're in a public place, the default hostname "Galaxy S23" tells a hacker your exact phone model. Knowing your model makes it easier to find a specific exploit or attack. Changing the hostname to something more neutral, such as "User_Device_01," slightly improves your digital hygiene.
However, it's important to understand that changing the name isn't a panacea. More important is using the latest Android security versions and avoiding connecting to open, unsecured WiFi networks. The device name is just one of many identifiers your phone broadcasts.
⚠️ Attention: Changing network settings may temporarily interrupt the connection to your smart home. Ensure that your IoT devices (lamps, sockets) are not hard-coded to the old hostname if you use complex automation scenarios.
In corporate networks, administrators often use device names to identify and enforce access policies. If you're connecting a personal phone to the work network, changing the name to something more descriptive (e.g., "Ivan_Phone") can make it easier for IT staff to block or troubleshoot access issues.
What is MAC address randomization?
This is a security feature that changes the unique physical address of the network card when connecting to different WiFi networks. This prevents your movements from being tracked by access points' geolocation, but can cause issues with device identification on the home network.
FAQ: Frequently Asked Questions
Does changing the phone name affect WiFi speed?
No, changing the device's text identifier does not affect data transfer speed, signal strength, or connection stability. This is a purely logical parameter for user convenience.
Is it possible to use Cyrillic characters in the device name?
Technically, modern Android smartphones allow you to enter Russian letters. However, when connected to older routers, printers, or Bluetooth-enabled cars, hieroglyphs or gibberish may appear instead of letters. It's best to use the Latin alphabet.
Will the name be reset after a system update?
In most cases, user settings, including the device name, are retained after updating the operating system. However, a hard reset will revert the name to the factory default.
Why does the router still show the phone model instead of the specified name?
Some routers ignore the name sent by the client (DHCP Hostname) and identify the device based on the MAC address database (OUI). In this case, you can only change the display name in the router's settings by finding the appropriate option in the client list.
Do I need Root rights to change the name?
No, you don't need root privileges to change the device name, access point, or Bluetooth interface. This is a standard operating system feature available in normal mode.
