Hidden Code Lets OnePlus and Oppo Users Replace Google Phone Dialer

Daniel Cross 0 comments 2 min read

A hidden dialer code allows OnePlus and Oppo users to replace the default Google Phone app with the native dialer for anonymous call recording.

Google Phone users on OnePlus and Oppo devices can now access a hidden dialer feature that swaps the default app for a native alternative. This change matters because the native dialer supports anonymous call recording without triggering the mandatory 'This call is being recorded' voice announcement that the Google app enforces. Users who prioritize privacy or discreet recording will find this switch useful, provided their device meets specific software requirements.

Native dialer enables anonymous call recording without mandatory voice announcements

The method relies on a specific dialer code that triggers a system prompt to install the Oppo or OnePlus Phone dialer. Users must dial `*#*#677776#*#*` in their current Phone app, after which a prompt asks them to restart the device. Once the phone reboots, the native dialer is installed and can be selected as the default Phone app.

  • Dialer Code: *#*#677776#*#*
  • Minimum Software Version: 16.0.10.501
  • Supported Devices: OnePlus 12, OnePlus 13, Oppo Find X8, Nord CE models
  • OS Requirement: Android 16

The hidden code triggers a system prompt to install the alternative dialer.

To use this feature, the phone must run Android 16 with the August security patch and software version 16.0.10.501 or newer. Reports confirm the method works on flagship devices like the OnePlus 12 and 13 series, as well as the Oppo Find X8 series and budget Nord CE models. The native dialer also supports Live Updates introduced with ColorOS 16 and OxygenOS 16.

The feature is currently confirmed working on Indian region models, but availability in other markets remains uncertain. Local regulations may prevent the feature from working on models sold in Europe or the US, and it is unclear if Oppo or OnePlus will ever enable it in those regions. The code is pre-installed in the software package but hidden from the user interface by default.
