I know you want to auto-record calls without notice on Android 10 and 11. But you don’t want to root your phone. You can download and use this Octavi Dialer Recovery Flashable zip with Call Recording. Its design is inspired by OnePlus Oxygen OS 11. This app is designed by Octavi OS Team.

In the next 3 minutes, you will be able to record calls in Android without any app. Google phone dialer is good in everything except call recording. But this Oxygen OS dialer is great in terms of everything.
You can also auto record all calls in high quality. Both the people will be heard clearly in the recording. This is a system-level app so the recording will be of top-notch quality. This won’t show any notifications while the call is being recorded. This won’t announce to the other person that the call is being recorded.
If you’re in the same boat as me and fall into any of the following situations, you should get this zip and flash it on your phone:
- You have an unrooted phone and the bootloader is unlocked and recovery is installed.
- You want to record calls without the other person knowing
- You love the Oxygen OS phone dialer and want to use it on a non-OnePlus phone or any custom ROM out there.
Important Notes:
- Call recording is working perfectly. It is quite clear and both the persons in conversation can be heard clearly. Remember that my phone is not rooted and I have just flashed this zip with TWRP recovery. That means you don’t have to be rooted to get the call recording working properly.
- This can also be flashed on your phone if you have magisk installed. but do not flash it in magisk, flash it in your custom recovery.
- It can be flashed on all types of custom ROMs. on the other hand, it might not work on stock ROMs such as MIUI, VOS, and Color OS.
- If you are concerned about your phone’s security, you can turn on Android Phone Encryption from settings.

How I created this Octavi Dialer flashable zip for Android?
Octavi OS developers and designers developed this great phone dialer application. To use this great app in other ROMs such as Pixel Experience, ShapeShift OS, Spark OS, EvolutionX, etc, a flashable zip was to be created. As a result, everyone can use this app, without root and any call recording notice.
Due to the recent news of Magisk having problems with the safety net, I thought to completely unroot my phone. Therefore, I created it as a recovery flashable, not a magisk module. If you have recovery in your phone, you can flash zips and customize most of the things without needing Magisk.
Special thanks to:
- Almighty Allah
- Octavi OS Developers and Designers who developed this application for Android
- Oxygen OS developers for the inspiration and icons
- ElonMods for generating the permissions XML
- Me for creating the zip to be flashable on all ROMs especially Pixel ROMs
- Finally, to those who will use it: YOU 🙂
Conclusion
I spent months finding out ways to record calls in android without notice. Luckily, I found the Octavi Dialer application but it was not recording calls. It had to have system level access to in-call audio. Therefore, I created this Octavi Dialer recovery flashable zip for all android phones. Now, auto-call recording works on Android 11 without any problems.
