SystemInfo.deviceUniqueIdentifier returns empty string on LG-AS110

I’m using unity 2018.4.8f1 and use SystemInfo.deviceUniqueIdentifier as identifying user.

But LG-AS110 and Android 6.0.1(API23) while Google tests, Unity crash report shows like this.

So I make it send logs that contains SystemInfo.deviceUniqueIdentifier value, and it shows empty string.

Why it returns empty string? Is it error of SystemInfo.deviceUniqueIdentifier?

anyone?

It might be unsupported. Android can be hit and miss especially with +15,000 devices. Try this Unity - Scripting API: SystemInfo.unsupportedIdentifier to see if it is giving unsupported back to you. If it isn’t I would submit a bug report.
