Download ACR Phone Helper (APH) with Shizuku support for Android 10+

Other stores coming soon...

APH can use Shizuku to enable real two-way call recording, including calls made with Bluetooth devices and wired headphones.

Compared to using an Accessibility Service, Shizuku method is more powerful and less invasive, it usually requires fewer ongoing steps once set up.
Shizuku works by granting elevated permissions through Android's debugging features. Only proceed if you are comfortable enabling Developer Options on your device.

 

Setup

1. Download and install APH using the links provided above.
2. Enable Developer Options on your phone:
   • Stock Android / Pixel
     Settings → About phone → Tap Build number 7 times
   • Samsung Galaxy
     Settings → About phone → Software information → Tap Build number 7 times
   • Xiaomi / Huawei / Others
     Settings → About device → Version or Build number → Tap 7 times
3. Download and install Shizuku:
   • From Google Play: Play Store link
   • Or from GitHub: GitHub repository
4. Activate Shizuku by following the official user guide: https://shizuku.rikka.app
   You do not need root your phone. You can activate it either:
   • Using a computer (ADB)
   • Directly on the device via Wireless Debugging
5. Open APH and tap the on-screen button to grant Shizuku permission when prompted.
6. That's it. You can now enjoy real two-way call recording, including calls over Bluetooth and headphones.

Download ACR Phone Helper (APH) with Accessibility Service for Android 10+

Please do not forget to rate ACR Phone once you are happy. Many people are blaming Google's policy change on us and simply giving 1 star reviews without contacting us. Our hands are tied. Google Play Store Policies are so strict, we cannot even mention APH in ACR Phone let alone linking to APH download page.

 

Installation Video

Here's a video that shows how to install ACR Phone Helper (APH) with Accessibility Service from the NLL Store and activate its Accessibility Service. If your phone uses one of the other app stores listed above, you can install it from there instead by tapping the corresponding icon.

Accessibility Service issues

Please note that some phones have aggressive power management features and can turn off APH Accessibility Service. Try following if you get notifications about Accessibility Service being disabled.

• Enable Notification option in APH
• Add APH to protected apps (see https://dontkillmyapp.com for how to)
• Do not close ACR from recent apps screen by swiping away or clearing your phone's memory

 

History and Accessibility Service info

Call recording by 3rd party apps completely blocked by Google on Android 10+. The only way to record any audio was using Accessibility Service APIs.

Starting from 11th May 2022 Google Play Store has banned Accessibility Service usage for call recording on apps published on Google Play Store. In order to overcome this limitation, we have created a companion app for of ACR Phone called ACR Phone Helper (APH). You simply continue installing ACR Phone from Google Play Store and install ACR Phone Helper (APH) to activate call recording as before.

ACR Phone would only record silent audio without ACR Phone Helper (APH) and would warn you about its limitation.

Please note that ACR Phone is not just a call recorder. While call recording may be seen as its main feature due to our previous call recording app ACR Call Recorder (legacy). It is one of many features of ACR Phone. Please explore rest of its features at nllapps.com

 

Call recording quality with Accessibility Service

ACR Phone with ACR Phone Helper (APH) cannot improve call recording quality but prevents silent recording. Try below options for best possible call recording.

• Remove any other call recording apps and turn off legacy ACR Call Recorder if it is still installed.
• Try changing Audio Encoder in Recording settings.
• Try adjusting Recording Audio Gain under Call Recording Settings
• Try enabling loud speaker to see if it helps.
• Make sure you are not using any headphones of Bluetooth headset.
• Make sure Wi-Fi calling is not enabled.
• Open Accessibility Settings of your phone and toggle ACR Phone Helper (APH) off and then on again.
• Keep ACR Phone on the screen. Some phones can only record when ACR Phone is on the screen and screen is on.
• Do not close ACR Phone and ACR Phone Helper (APH) from recent app and apply settings from https://dontkillmyapp.com/

Unfortunately, there is nothing we can do if above information doesn’t help. This issue will be same with all call recording apps.

Why do you need to go through all this?

Call recording on modern Android devices is no longer a straightforward technical feature. It is primarily constrained by platform policy. Google progressively blocked third-party access to call audio from Android 10 onward. In May 2022 it formally prohibited the use of Accessibility Service for call recording in apps distributed via the Google Play Store. These rules apply to all developers without exception. As a result, apps published on Google Play cannot include functional call recording, nor can they reference or link to alternative components that restore this capability.

We have adopted a companion-app approach to work around this policy. ACR Phone remains available on Google Play as a phone app, while ACR Phone Helper (APH) is distributed through alternative app stores. Call recordings on Android 10 and above will contain no audio without APH.

APH enables call recording either via Accessibility Service or through the newer Shizuku-based method, which provides real two-way recording including Bluetooth and wired headset calls without relying on Accessibility APIs.

While this setup involves additional steps, it reflects the current reality of Android’s restrictions. There are no functional call recording apps on Google Play because the policy does not allow them to exist. Until Android introduces an officially supported, privacy-respecting call recording API, companion-app model remains the only viable way to provide reliable call recording on modern Android versions.
