Enabling automatic call recording on modern smartphones has become a difficult task due to the tightening of Google's security policies. Starting with Android 9 and especially Android 10-14, the access of third-party applications to the microphone and audio stream during a call was significantly limited. Users who try to activate the function through a popular application ACR (Another Call Recorder)are often faced with the fact that the recording is carried out without the sound of the interlocutor or does not start at all.
However, the need to preserve important agreements, legal evidence or simply memorable conversations has not disappeared. There are specific methods for bypassing system restrictions that allow you to return functionality automatic recording. In this article, we will look in detail at how to properly configure ACR and its modifications, what system parameters need to be changed, and what to do if the standard solution does not work on your device.
Why call recording stopped working on new Android
The main reason for the problems lies in the changes to the Android API that Google has implemented to protect user privacy. Previously, applications could intercept the audio stream directly from the system, but now privacy policy denies access to the microphone during an active telephone conversation for third-party software. This means that the standard version of ACR from Google Play often records only your voice or silence.
Smartphone manufacturers are also making their own adjustments. Shells like MIUI, OneUI or ColorOS may have their own built-in voice recorders that conflict with third-party solutions. If you have native recording enabled in your phone settings, the ACR app simply won't be able to access audio resources. In some cases, the system forcibly terminates the recording process, considering it a security violation.
It is worth considering that the legislation of different countries also affects the availability of functions. In some regions, recording a conversation without warning the other party is prohibited, so manufacturers programmatically disable this feature at the firmware level. Before installing any software, make sure that your actions do not contradict local communications laws.
⚠️ Attention: On devices with Android 11 and higher, recording calls through third-party applications without root access may be technically impossible due to hardware limitations of the system kernel.
Installing and configuring the classic version of ACR
First, you need to download the current version of the application. The official client in the Google Play Store often has reduced functionality due to the requirements of the store. Experts recommend downloading version ACR Unchained or modified assemblies from trusted resources, as they contain special scripts to bypass blocking. Once installed, launch the application and grant all requested permissions.
A critical step is setting up the audio source. In the ACR settings menu, go to the Audio Sources section and experiment with the different options. Different capture methods are suitable for different processors and versions of Android: Voice Call, Voice Communication or Mic. If the wrong source is selected, you will receive a file with silence instead of conversation.
Don't forget to activate automatic recording start. In the main settings, find the "Automatic recording" switch and make sure it is turned on. It is also recommended to set up filters to avoid recording spam calls or short tones. You can create rules according to which recording will be carried out only for contacts from the phone book or, conversely, only for unknown numbers.
☑️ Checking ACR settings
Using ACR Unchained and alternative builds
The standard version of the application is often powerless against Google's new security mechanisms. That is why the developer community created the version ACR Unchained. This modification disables compatibility checks and attempts to exploit all available system loopholes to capture audio. You can download it only from third-party sites, since it is prohibited in the official store.
When using alternative assemblies, it is important to correctly configure the recording method. In advanced settings ACR Unchained you can choose between the standard API and methods that require special access rights. If your phone is not rooted, try switching the method to Accessibility Service (Accessibility). This will allow the application to simulate pressing the record button on the screen, if such a function is available in the native dialer.
However, even the Unchained version does not guarantee 100% results on all devices. On Xiaomi or Samsung smartphones with the latest security updates, recording may be unstable. In such cases, it is worth considering alternative applications, such as Cube ACR or Boldbeast Call Recorderthat use their own drivers to capture audio.
Why is ACR Unchained better than the regular version?
The regular version is subject to Google Play rules and disables recording functions on new Androids. Unchained ignores these restrictions and uses low-level audio access methods, which increases the chance of successful recording, but requires manual installation of the APK file.
Configuring accessibility and battery exceptions
The Android system tends to “kill” background processes to save power. In order recording assistant to work smoothly, you need to add the application to the battery optimization exceptions. Go to Settings → Applications → ACR → Battery and select the “No restrictions” or “Do not optimize” mode. Without this step, the recording may be interrupted a few seconds after the call begins.
Another important aspect is access through accessibility. Many modern recorders require accessibility services to be enabled in order to function correctly. Go to Settings → Accessibility and find your recording application in the list. Activate the switch and acknowledge the system warning. This will allow the application to “see” the call screen and respond to incoming calls instantly.
Also check your background permissions. Some shells (for example, MIUI or EMUI) have a separate “Autorun” item. Make sure it is enabled for ACR. If the system limits background activity, the application simply will not have time to start the recording mechanism before you pick up the phone.
Comparison of popular applications for recording conversations
If ACR doesn't do the job on your device, it makes sense to test the competition. Different apps use different audio capture algorithms, and what doesn't work in one may work perfectly in another. Below is a table comparing the key characteristics of popular solutions.
| Application | Work without Root | Record your interlocutor | Cloud storage | Compatibility |
|---|---|---|---|---|
| ACR Unchained | Partly | High | Yes (Google Drive) | Android 9-13 |
| Cube ACR | Yes | Medium | Yes | Wide |
| Boldbeast | Yes (with settings) | High | No | Specific |
| TapeACall | Yes (via conference) | Excellent | Yes (paid) | All versions |
The application TapeACall uses a unique method: it creates a conference call with its own recording server. This bypasses any Android system locks, since the recording occurs on the server side, not the phone. However, this method is usually paid and requires a stable Internet connection. For one-time important calls, this may be the best solution.
Boldbeast Call Recorder famous for its advanced sound settings. It allows you to manually adjust microphone gain and noise reduction. If other apps record your conversation partner too quietly, Boldbeast can often correct this programmatically, but the app's interface may seem overwhelming to a newbie.
⚠️ Note: Settings interfaces and menu item names may vary depending on the version of Android and your smartphone model. Always check the latest guides for your specific firmware.
Solving problems with no sound from the interlocutor
The most common complaint from users is that they are recording, but only themselves can be heard. This occurs when the application cannot access the other person's voice stream (uplink). Try turning on speakerphone during a call. In this case, the sound of the interlocutor will go through the speaker, and the phone’s microphone will be able to pick it up. This is an “old-fashioned” method, but it always works, even on the most secure systems.
In the ACR settings, find the “Recording Settings” item and try changing the “Audio Source” parameter. Go through all available options: Default, Mic, Voice Call, Voice Uplink, Voice Downlink. Save your settings and make a test call after each change. Often, switching to Voice Communication solves the problem on Android 10+.
If all else fails, check to see if your antivirus or built-in system defender has blocked access to the microphone. In rare cases, resetting the settings of the recording application itself (not the phone!) to factory settings helps. Delete the application cache in the menu Settings → Applications → ACR → Storage → Clear cache and try setting it up again.
If recording only works with the speakerphone on, try using a headset. Some headphone models allow the system to correctly route the audio stream for recording.
Advanced methods: root access and Magisk modules
For users who are ready to take radical measures, obtaining root access opens full access to the system. With root privileges, the ACR app can record audio directly from the system kernel, bypassing any Google restrictions. This guarantees ideal quality of recording of both sides of the conversation.
Owners of devices with an unlocked bootloader and installed Magisk special modules are available, such as Call Recording Enabler. These modules modify the system libraries to return native recording functionality to the Phone app. This is the most elegant way, since it does not require installing third-party recorders.
However, obtaining root access will void the warranty on the device and may lead to banking applications not working (although this can be treated through Magisk Hide). Use this method only if you are confident in your actions and understand the risks. For most users, a correctly configured version of ACR Unchained is sufficient.
Having root access is the only way to guarantee 100% performance of call recording on any version of Android without compromises in sound quality.
Is it safe to use modified versions of ACR?
Using third-party APK files always carries risks certain risk. Download applications only from trusted forums (for example, 4PDA or XDA Developers), where files are reviewed by moderators. Avoid dubious sites that offer “hacked” versions, as they may contain malicious code.
Is it possible to recover a deleted call recording?
If you have not set up synchronization with the cloud (Google Drive, Dropbox), it is almost impossible to recover a deleted file from the phone’s internal memory. Third-party data recovery apps rarely help with files deleted from specific recording application folders.
Why did recording stop working after updating Android?
Google regularly closes loopholes in new versions of the operating system. What worked on Android 11 may be blocked in Android 12. In such cases, you need to wait for an update to the ACR application itself or switch to alternative recording methods.
Are calls from instant messengers (WhatsApp, Telegram) recorded?
Ordinary telephone recorders cannot record calls through Internet instant messengers. This requires special functions in applications like Cube ACR, which use the accessibility service to capture audio from specific applications, but this is also unstable.
