Owners of flagship smartphones Samsung Galaxy often face the need to record important information from a telephone conversation. The model Galaxy S8, released in 2017, has long remained the standard of performance, but with the update of the operating system, users were faced with limitations. The question of how to record conversations on Android in this model is no longer trivial due to changes in the privacy policy Google.
Starting with version Android 9 Pie, the company Google blocked access of third-party applications to the microphone during a call. This means that the usual utilities from the store Play Market stopped working correctly or disappeared altogether. However, for owners Samsung S8 there are workarounds and specific settings that allow you to bypass these restrictions. In this article we will look at all the legal and technical ways to save the audio track of a conversation.
It is worth noting right away that the effectiveness of the method depends on the region in which the phone was purchased and the current firmware version. European versions of devices often lack built-in recording functionality out of the box, while Asian models have this option at the system level. We will analyze the nuances for both cases and offer working solutions.
Checking the built-in call recording function
First of all, you need to check whether the native recording function is available to you. In smartphones Samsung this option is integrated directly into the Phone application. If your device has the appropriate firmware, you will not need to install additional software. Go to the dialer application and pay attention to the interface during an incoming or outgoing call.
To activate the function, click on the menu button (three dots) in the corner of the call screen. If you see the item Call recording, you are lucky - the system officially supports this option. In some cases, the button can be placed on the main dialing screen for quick access. To do this, go to Settings → Call buttons and activate the switch.
If the menu item is missing, this does not mean that the function is unavailable forever. Often it is hidden in deep settings or depends on the SIM card. Try going to the settings of the Phone application itself through the main menu of your smartphone. Find the section Call recording and check whether you can enable automatic recording for all numbers or only for selected contacts.
⚠️ Attention: Even if there is a record button, in some regions, when you press it, the interlocutor will hear a loud beep indicating the start of recording. This is a legal requirement and cannot be disabled programmatically.
If the built-in recording is not available in the menu, try changing the region in the phone settings (CSC), but this action may void the warranty and requires a data reset.
Using third-party applications on Android 9 and higher
The situation has changed dramatically with the release updates Android 9. Developers of call recording applications, such as Call Recorder - ACR or Cube ACR, were forced to look for new methods of capturing sound. The standard API no longer allows you to intercept the audio stream, so applications use accessibility services (Accessibility Services).
When installing such software on Samsung S8 you will be asked to provide extended permissions. This is necessary so that the application can emulate clicks or intercept system call events. Without granting these rights, the recording will either be absent or contain only your voice without the voice of the interlocutor.
- 📱 Cube ACR —one of the few applications that successfully bypasses restrictions through a special applet (Cube ACR App Connector).
- 🎙️ Call Recorder - ACR —requires manually setting the audio source to “Voice Call” or “Voice Communication” in experimental settings.
- 🔧 Truecaller —a popular caller ID that has also implemented a recording function that works through cloud servers in some regions.
It is important to understand that the operation of such apps is unstable. After the next monthly security update Android the application may stop recording the interlocutor. In this case, you need to go to the application settings and try to change the sound source or reinstall a special plugin, if it is offered by the developer.
Setting up sound sources and microphone
The main problem when recording on modern versions Android is silence in the file instead of the interlocutor's voice. This happens because the system blocks access to the internal audio stream. To fix this, you must manually select the correct recording source in the settings of third-party applications.
Go to the settings of the selected recorder and find the section Sound sources or Audio Source. By default there is often "Microphone". Try switching this parameter to Voice Call, Voice Communication or Voice Uplink/Downlink. On the processor Exynos 8895, which is installed in S8, some combinations work better than others.
Recommended sequence of testing sources:1. Voice Call
2. Voice Communication
3. Microphone (with speakerphone enabled)
4. Default
If none of the software sources provides clear sound, the only reliable option is to use speakerphone. In this case, the application will record sound through the external microphone of the smartphone. The quality will be. below, there may be an echo, but the dialogue will be saved in full.
☑️ Checking the recording quality
Comparison of recording methods: table of characteristics
For clarity, let's look at the main methods of recording conversations on Galaxy S8 in the comparative table. This will help you choose the best option depending on your priorities: sound quality, convenience or legality. method.
| Method | Sound quality | Complexity of setup | Risk of blocking |
|---|---|---|---|
| Built-in function | Ideal (digital) | Minimal | Absent |
| Cube ACR (App Connector) | Good | Average | Average (depending on updates) |
| Speakerphone + Voice recorder | Low (noise, echo) | Absent | Absent |
| root access + Module | Ideal | High | High (loss of warranty) |
As can be seen from the table, the presence of a built-in function is the uncontested leader. However, if your device is from Europe, you will have to make compromises. Using root access gives full control over the system and allows you to record conversations at the kernel level, but this is not the case. voids the warranty and may disrupt the operation of banking applications due to the activation of protection Knox.
⚠️ Attention: Obtaining superuser rights (Root) on the Samsung S8 irreversibly triggers the physical Knox fuse (0x1). After this, Samsung Pay, Secure Folder and some will stop working forever. security features.
Legal aspects and ethics of recording
Before setting up automatic recording of all incoming calls, it is worth familiarizing yourself with the laws of your country. In most states, recording a conversation without warning the interlocutor is illegal or restricted. Violation of these rules may result in administrative or criminal liability, especially if the recording is used as evidence in court.
Technically Samsung S8 allows you to record conversations discreetly (secretly), but the ethical side of the issue remains on the conscience of the user. If you record a conversation for the purpose of personal memory or recording agreements, problems usually do not arise, however, publishing such recordings in the public domain without the consent of the other party is strictly prohibited.
Built-in software Samsung often automatically plays a sound notification for both participants in a conversation when recording begins. This is done specifically to comply with legal regulations. Third-party applications may not have such a notification, which shifts the responsibility entirely to the owner of the device.
Is it possible to disable the sound warning?
In official firmware, it is impossible to disable beep when recording, since it is hardwired at the modem B level. In custom firmware (LineageOS, etc.), this function can be removed by editing system files, but this requires deep knowledge of Android.
File management and storage of records
Recorded files take up space in the internal memory of the smartphone. The Galaxy S8 basic version has 64 GB, which can quickly fill up when actively recording in high quality. Files are usually saved in the format .m4a or .mp3 in a folder Call or Recordings in internal storage.
It is recommended to regularly transfer archives to a memory card microSD or to cloud storage. In the settings of the recording application, you can specify the saving path. If you use the built-in recorder, the files are often located in a hidden system folder, which can only be accessed through a file manager with access rights to system directories.
To easily search for specific conversations, use the sort function by date or contact name. Many apps allow you to add voice notes to a recording immediately after the call ends. This helps you quickly navigate through the archive without listening to each file in its entirety.
Regularly cleaning the folder with recordings is critical for the Samsung S8, since a lack of free memory can lead to interface slowdowns and camera malfunctions.
Frequently asked questions (FAQ)
Why after Android 9 update, the recording button is missing?
Google has made changes to the operating system security policy, prohibiting third-party applications from accessing the audio stream during a call. The built-in function could disappear if you updated the firmware to the European version or reset the region settings.
Only my voice is recorded, the interlocutor cannot be heard. What to do?
This is a classic problem of the microphone being blocked by the system. Try changing the sound source to “Voice Call” in the settings of the recorder application or turn on the speakerphone during a call. Also check if the antivirus is blocking the application's access to the microphone.
Is it possible to restore a recording if it was accidentally deleted?
If the file was deleted from the application trash, the chances are low. However, you can try using data recovery apps on your PC by connecting your phone in USB debugging mode. The less time has passed since deletion and the less new data is recorded on the phone, the higher the chance of success.
Does recording conversations affect the rate of discharge of the S8 battery?
The recording process itself consumes a minimal amount of energy. The main consumption comes from the communication module and screen. However, the constant operation of background services of third-party applications may slightly increase battery consumption in standby mode.
Where are recordings from the built-in Samsung function stored?
Usually they are located in the Voice Recorder application in a separate Phone tab or in the file manager along the path: Internal memory → Recordings → Call. They can also be accessed through the call history by clicking on a specific number.
