I've written a React Native app and need to test it on a Samsung Galaxy S10 emulator. When I look at the OSs available for Android Studio emulators, I don't see the S10. Is there a way to get it?
Use Genymotion, you can find S10 and many other devices there.
And it's faster than AVD provided in Android Studio too.
Once downloaded, don't forget to install GApps to it.
