Modern smartphones such as Samsung Galaxy A52, have long ceased to be simple devices for making calls and have become powerful tools for work and entertainment. One of the most popular features, turning the device into a full-fledged router, is the ability to create a hotspot. This is especially useful when traveling, when landline internet is unavailable and a laptop or tablet urgently needs a global connection. Owners of this model Galaxy A52 often look for ways to make the most efficient use of their device's resources for distributing traffic.
The process of activating modem mode in the shell One UI Samsung's setup is extremely simplified and takes just a few seconds, but many users aren't aware of the hidden settings that can secure the connection or save battery life. Properly configured settings can turn your smartphone into a reliable internet source for a whole group of devices. In this article, we'll cover all the setup details, potential issues, and solutions so you can confidently manage your connection.
Before moving on to specific steps, it's worth noting that the quality of the data connection directly depends on the quality of the received cellular network signal. If your smartphone shows 3G or unstable LTE, the speed on connected devices will be similar. Therefore, before starting, make sure you are in an area with a strong signal from your carrier.
Basic activation of the access point via the curtain
The fastest way to start distributing internet on Samsung A52 — using the quick settings panel. This method is ideal for situations where you need to establish a connection immediately and don't have time to tweak the interface in depth. A single tap is all it takes to initiate the signal broadcasting process.
To do this, unlock the screen and swipe down from the top of the display to open the notification shade. If the icon you need isn't on the first page, swipe left or right to reveal hidden buttons. Find the icon labeled "HotSpot" or "Mobile Hotspot" and tap it.
Once activated, the icon will turn blue, indicating that tethering has been successfully activated. Other devices can now see your phone in the list of available Wi-Fi networks. However, using this method forces you to use the default security and network name settings, which are best changed to protect your data.
Important: By default, the system may use a random network name and a complex password that is difficult to enter manually on another device. It is recommended to access the full settings menu at least once to remember or simplify your login information.
Detailed configuration of network parameters in the menu
For advanced configuration, you need to go to the system settings menu. Here, the user has full control over the network name, encryption type, and frequency range. This is a critical step for ensuring the security and stability of the connection, especially if you're in a public place.
Open the Settings app, select Connections, and go to Wi-Fi Hotspot & Tethering. This is where all the key controls are located. Tapping the "Wi-Fi Hotspot" text (not the toggle) will take you to the detailed configuration menu.
In the window that opens, you'll see the current network name and password. By clicking the "Network Name" field, you can create any name you like, which will be displayed when searching for Wi-Fi on other devices. The "Password" field allows you to set a character combination that's easy to remember but difficult to brute-force.
Particular attention should be paid to the "Range" parameter. Samsung A52 Broadcast frequency settings are available. Band selection 2.4 GHz will provide better compatibility with older devices and a longer range, but the speed will be lower. Switching to 5 GHz will provide the maximum data transfer speed, but the signal range will be reduced, and some older laptops may simply not see the network.
Setting up security and restricting access
Security is paramount when using public internet over a mobile network. An open hotspot is a direct route to personal data leakage, so using encryption protocols is essential. In the settings Galaxy A52 Powerful tools for connection control are provided.
In the access point menu, find the "Security Type" option. Make sure the standard is selected. WPA3-Personal or, at least, WPA2-PersonalThese protocols encrypt traffic between your phone and the connected device, protecting data from interception. Open mode is strongly discouraged.
Another useful feature is the "Allowed Device List," or managing connected clients. In this section, you can see the MAC addresses of all devices currently using your data. If you spot an unknown device, you can immediately block it by clicking the corresponding button next to its name.
⚠️ Caution: Never leave your hotspot open without a password in crowded places such as cafes, airports, or shopping malls. Attackers could intercept your data or use your connection for illegal activities.
A "Hide Device" feature is also available. When enabled, your phone will stop broadcasting the network name in the public list. To connect, the user will have to manually enter the exact network name (SSID) and password in the Wi-Fi settings on the receiving device. This provides an additional layer of privacy.
Battery saving and traffic management
Hotspot mode is one of the most power-hungry processes for a smartphone. Active Wi-Fi and LTE/5G operation simultaneously leads to rapid heating of the case and draining of the battery. For owners Samsung A52 You should be aware of built-in optimization mechanisms that will help extend battery life.
The "Wi-Fi Timeout" option is available in the hotspot settings menu. You can set a time interval (e.g., 5 or 10 minutes) after which the hotspot will automatically turn off if no active device is connected. This prevents you from forgetting to turn off the hotspot and wasting battery.
There's also a traffic limit feature. You can set a data limit after which data tethering will stop. This will prevent unexpected charges if you don't have an unlimited data plan. The setting is located in the "Traffic Limit" section.
Why does the phone get so hot when distributing?
When both the cellular receiver and Wi-Fi transmitter are active, the processor and radio module operate at their maximum capacity, causing heat generation. Remove the case for better heat dissipation.
To maximize battery savings, it's also recommended to reduce screen brightness or turn off the display completely while sharing. A bright screen combined with active data usage guarantees the phone's battery will run out within an hour and a half of intensive use.
Using USB modem and Bluetooth
It's not always practical to use wireless data transfer. If you need to ensure a stable connection for a desktop computer or laptop without built-in Wi-Fi, Samsung A52 offers alternative connection options via cable or Bluetooth.
USB tethering allows you to share your internet connection via your charging cable. This solution has two key advantages: eliminating latency (ping) and simultaneously charging your smartphone. To activate, connect your phone to your PC using a cable, go to "Settings" → "Connections" → "Tethering & Hotspot," and toggle the "USB tethering" switch.
The system will automatically install the necessary drivers, and a new network connection will appear on your computer. This method is also useful if the phone's Wi-Fi module is faulty or unstable due to interference.
A Bluetooth modem is another option that uses less power than Wi-Fi but offers significantly slower speeds. It's suitable for text messaging or checking email, but not for watching videos. To connect, you need to pair the devices via Bluetooth and enable the corresponding option in the modem menu.
☑️ Check before turning on the USB modem

Solutions to common problems and errors
Despite the reliability of the system Android and shells One UI, users may encounter situations where the internet is not available or connected devices are unable to obtain an IP address. Most often, the problem lies with APN settings or network service outages.
If your devices see the network but can't connect, try changing the encryption standard from WPA3 to WPA2. Some older devices don't support the latest security protocols. Resetting your network settings can also help: go to "General Settings" → "Reset" → "Reset Network Settings."
If you have internet access on your phone but pages won't load on your connected laptop, check your carrier's access point name (APN) settings. Sometimes providers block data sharing on unlimited internet plans. In such cases, you may need to change a setting. APN in the mobile network settings (adding a symbol # or change the APN type to dun), however, this depends on the operator's policy.
⚠️ Please note: Telecom operators may monitor TTL packets and block tethering if this is prohibited by your plan. Changing system settings to bypass blocking may violate the terms of your contract with your operator.
Another common cause is a full network service cache. In this case, simply turning on airplane mode for 10-15 seconds and then turning it off helps. This forces the device to re-register with the mobile network.
Why is the hotspot button grayed out?
This can happen if power saving mode is enabled, which blocks background processes. The hotspot also won't work if Wi-Fi Calling is enabled or the smartphone is connected to another Wi-Fi network in repeater mode (depending on some software versions).
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
On Samsung A52 Wi-Fi Sharing is available in Android 8.1 and newer versions. It allows you to receive and share internet data over Wi-Fi, saving mobile data. To do this, simply turn on the hotspot when Wi-Fi is already active.
How many devices can be connected to Samsung A52 at the same time?
The technical specifications allow for connecting up to 10 devices simultaneously. However, if more than 3-4 active users are connected, the internet speed on each device may drop significantly, and the phone may become very hot.
