APH includes Shizuku built directly into the app no separate Shizuku app needed. This enables real two-way call recording, including calls over Bluetooth and wired headphones.
This is the recommended method for most users. Compared to Accessibility Service it is more powerful, less invasive, and generally requires fewer ongoing steps once set up. Shizuku works by granting elevated permissions through Android's debugging features. You will need to enable Developer Options, but root is not required.
Shizuku must be running for APH to work correctly. If you reboot your phone, you may need to reactivate it. APH will prompt you when needed.
For the smoothest experience, disable battery optimisations for APH.
Recording both sides may not be possible on some phones when Wi-Fi calling is active. This is an OEM audio driver limitation and is not specific to APH.

APH also works with the standard Shizuku app if you already have it installed or prefer to manage Shizuku yourself. This delivers the same real two-way call recording (including Bluetooth and wired headphones) as the built-in option.
Choose this option if you use Shizuku with other apps, or if you prefer to control Shizuku independently.
Shizuku must be running whenever APH needs it. After a reboot, reopen the Shizuku app to restart it.
Disable battery optimisations for both APH and Shizuku for the best experience.

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.
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.

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
ACR Phone with ACR Phone Helper (APH) cannot improve call recording quality but prevents silent recording. Try below options for best possible call recording.
APH Magisk Module provides real two-way call recording including Bluetooth/Headphones. Please make sure to uninstall normal APH before installing APH Magisk Module. Once installed, simply reboot your phone to activate.
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 through one of three methods: Accessibility Service (the original approach), built-in Shizuku (integrated directly into APH, no separate app required), or a 3rd party Shizuku app (for users who already manage Shizuku independently). The two Shizuku methods provide 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.
