Voice over LTE technology, known as VoLTE, has become the standard for modern smartphones, allowing voice calls to be transmitted over a high-speed 4G network. However, device owners Samsung Galaxy often encounter a situation where this function causes malfunctions: rapid battery drain, case overheating, or unstable sound quality. In such cases, there is an urgent need to deactivate the option manually, although manufacturers often hide the corresponding switches deep in the system menus.
The disabling process may vary depending on the shell version One UI and the regional firmware of your device. Sometimes the standard path through settings is not available, and the user has to resort to using secret codes or third-party software. It is important to understand that forced deactivation VoLTE may result in the phone switching to 2G or 3G networks during a call, which in some regions is no longer supported by telecom operators.
In this article we will analyze in detail all the available methods for deactivating voice calls via LTE on smartphones. Samsung. We will look at standard settings, hidden engineering menus and specific features of working with different models so that you can choose the safest and most effective way to solve your problem.
Why do users tend to disable VoLTE on smartphones
The main reason for not using this technology is increased power consumption. A communication module operating in constant data transmission mode to provide a voice channel creates additional load on the processor and radio module. This is especially noticeable on older models or in areas with unreliable 4G signal reception, where the phone is constantly looking for a stable connection, which leads to a critical decrease in battery life.
Another common problem is overheating of the device. During long conversations through VoLTE the smartphone body can become noticeably hot, which not only causes discomfort, but can also cause system throttling or accelerated battery wear. Users often notice that without activating this function, the phone remains cold even after an hour of communication.
It is also worth mentioning compatibility issues with specific telecom operators. Not all tariff plans support the technology correctly, which is why subscribers experience dropped calls, no sound, or the inability to get through. In such cases, temporarily disabling the function is the only way to restore stable voice communication.
⚠️ Attention: Before making changes to the network settings, make sure that your operator supports voice calls on 3G networks. In some regions, second and third generation networks are already disabled, and deactivating VoLTE will make it impossible to make calls.
Standard method of disabling through Android settings
The easiest and safest way to control the voice call function is the built-in smartphone settings menu. In most cases, developers Samsung gives the user direct access to this option, although its location may vary depending on the operating system version. First, you need to go to the main section of the device configuration.
Find the item responsible for connections, usually it is called Connections or Connections. Inside this section, select menu Mobile networks. There is a key switch here that allows you to activate or deactivate voice over LTE. If you see a checkmark next to the item VoLTE calls, just uncheck it.
In some firmware versions One UI this item may be hidden inside the submenu of a specific SIM card. If you have a device with two slots, make sure that you change the settings for the card you are making calls through. After changing the setting, the phone may require a reboot to apply the new network configurations.
☑️ Check before disconnecting
If after performing these steps the switch automatically returns to the active position or is missing altogether, this means that the telecom operator has blocked the ability to change this parameter at the network profile level. In this case, you will need to use more advanced methods described below.
Using the engineering menu for hidden settings
When the standard interface does not provide the necessary options, the service menu comes to the rescue, accessible through a special set of codes in the “Phone” application. This tool is intended for engineers and testers, but allows ordinary users to access hidden radio functionality. To enter the menu you need to dial the combination *#2263#.
After entering the code, a hidden menu will open RF Band Selection. Here you need to select the slot of the SIM card whose settings you plan to change. Next, you should select the item Band Preference, where you can manually specify your preferred frequency ranges. To disable VoLTE, you need to deselect the ranges responsible for voice transmission in LTE, or select a mode that does not support this function, for example, WCDMA or GSM.
Be extremely careful when changing parameters in this menu. Incorrect frequency configuration can lead to complete loss of signal or inability to register with the operator's network. It is recommended to write down the original values before making any changes, so that if necessary you can quickly return everything back.
What to do if the code does not work?
Some operators or regional firmware block access to the engineering menu by code #2263#. In this case, you can try alternative codes, such as #0011# to view the status or *#27663368595# to reset settings, but their use carries increased risks.
Using third-party applications for network management
If the built-in system tools and engineering menus do not give the desired result, you can use specialized software from the store. Google Play. There are a number of utilities developed by enthusiasts that allow you to forcibly change the network type and disable specific communication protocols without obtaining root access.
One of the popular solutions is the application Force LTE Only (4G/5G). Despite the name, it often allows you not only to record the 4G mode, but also to manage flags VoLTE. After installing the application, you need to go to the Method 2 (Android 11+) section or similar for your version of the system, where the phone settings window will open. In the list of parameters, find the item voice_network_type or enable_volte and change its value to disable or 0.
It is worth noting that the effectiveness of such applications greatly depends on the processor model and Android version. On new devices with shell One UI 5.0 and higher, access to these settings may be limited by Google security policies, which will make the utilities impossible to work without deep intervention in the system.
| Application name | Required rights | Compatibility | Risk of failure |
|---|---|---|---|
| Force LTE Only | No Root | Android 6-13 | Low |
| NetMonster | No Root | All versions | Minimal |
| Signal Info | No Root | Android 8+ | Medium |
| 4G Switch | Root / ADB | Old models | High |
When using third-party applications to change network settings, always take a screenshot of the original parameter values. This will allow you to quickly restore communication functionality in case of an error.
Features of disabling VoLTE on different Samsung models
The line of smartphones Samsung is extremely diverse, and the approach to setting up the network can differ significantly depending on the series of the device. The flagship models of the series S and Note often have a more closed settings architecture compared to the budget series A or M. This is due to the fact that premium devices are more often certified by telecom operators with strict requirements for supporting modern protocols.
On devices with processors Exynos access to hidden settings through the engineering menu is usually open by default. At the same time, versions of smartphones based on chips Snapdragonintended for the US or Chinese markets may have completely blocked access to changing radio module parameters without unlocking the bootloader. This creates additional difficulties for users who want to optimize communication performance.
Owners of folding smartphones such as Galaxy Z Fold or Flip, you should be especially careful. Due to the complex design of the antenna unit, incorrect frequency settings can lead to a significant deterioration in signal reception when folded. For such devices, it is recommended to use only standard shutdown methods, if available.
⚠️ Attention: On smartphones purchased from specific telecom operators (branded versions), the settings menu may be truncated. In such cases, disabling VoLTE is only possible by flashing the device to the global version of the software.
The impact of disabling the technology on communication quality and battery
After successful deactivation VoLTE users often notice significant changes in the behavior of the device. The most obvious benefit is a reduction in case temperature and an increase in battery life. The radio module no longer constantly holds the data channel for voice, which reduces the load on the power system and allows the phone to operate in a more economical mode.
However, there is another side to the coin. The sound quality during a call may deteriorate noticeably, since 3G and 2G networks use older codecs with narrower bandwidth. The caller's voice may sound muffled or static, especially if you are on the move and your phone frequently switches between cell towers.
In addition, connection establishment (dial-up) time may increase. In VoLTE mode, the call goes through almost instantly, whereas when dropped in 3G, the phone takes a few seconds to establish a channel and agree on protocols. For some users, this delay can become critical, especially in emergency situations.
Disabling VoLTE is a compromise solution: you gain in autonomy and temperature of the device, but you can lose in sound quality and dialing speed.
Frequently asked questions (FAQ)
Will the VoLTE icon return after reboot your phone?
Yes, in most cases, after rebooting the device, the network settings are reset to the default values set by the telecom operator or firmware. If you disable the function through the engineering menu or a third-party application, you will have to repeat the procedure every time you turn on the phone, unless you use specialized scripts or modules.
Can disabling VoLTE lead to loss of warranty?
Changing settings in the menu or entering service codes in itself is not grounds for denial of warranty service, since this does not entail damage to the hardware provision. However, if you used third-party software that requires rooting or unlocking the bootloader, this may void the manufacturer's warranty.
Why is there no VoLTE switch in the settings on my Samsung?
The absence of a switch usually means that your carrier has forced this feature at the network level and has hidden the option to disable it in the interface. This is a common practice to ensure communication quality in regions where there are 2G networks and
