java.security.NoSuchProviderException: no such provider: BC on Android 7

A small number of crashes occur in my apps, they only occur in some models of Android 7, mostly LG devices.

I am using org.bouncycastle.jce.provider.BouncyCastleProvider, as following code in my Android app:

private void setupBouncyCastle() {
Security.removeProvider(BouncyCastleProvider.PROVIDER_NAME);
Security.addProvider(new BouncyCastleProvider());
}

But it seems conscrypt library cannot find the provider. Is this a bug or usage error? Thank you.

Fatal Exception: java.lang.AssertionError: java.security.NoSuchProviderException: no such provider: BC
