+## OOS Call Recording Enabler
+Enables call recording feature in OxygenOS for "over-seas" users without changing region to China.
+
+## Background
+This is a Magisk alternative to a [build.prop method](https://forum.xda-developers.com/oneplus-3t/how-to/call-recording-oos-4-1-6-rooted-op3t-t3621652) originally introduced by [sparky vicky@XDA](https://forum.xda-developers.com/member.php?u=5196812)
+which was based on changing system-wide region to China, which resulted in quite many unpredictable side-effects for "over-seas" region users.
+Magisk module modifies only a necessary part of the system without changing current region.
+
+## Requiremenets
+- Magisk v12.0 or later
+- Version of OxygenOS should match version of the module for the best experience
+
+## What gets modified
+Module replaces stock in-call screen app (/system/priv-app/OPInCallUI).
+The one and only modification is that isSupportCallRecorder() method of OPPhoneUtils class was made to always return true.
+
+## Credits
+- [spark vicky@XDA](https://forum.xda-developers.com/member.php?u=5196812) for original build.prop method
+
+## Source code
+- [GitHub](https://github.com/C3C0/oos-call-recording)
+
+## Change log
+- 2017/06/16 -> initial release compatible with OxygenOS 4.1.6
+
+## Like it?
+Consider [buying me a coffee](https://forum.xda-developers.com/donatetome.php?u=5008415)
