www.callercenter.com reports that the (530) 392 exchange is managed by LEVEL 3 COMMUNICATIONS, LLC which is an American multinational telecommunications provider. The scammers are likely outside the country and thus difficult to prosecute or prevent from continuing to morph.
I got a call from this number and 2 minutes later from 916-778-4232. I missed this call and they didn't leave a message but I have a feeling both numbers are somehow related.
I had this issue once. Figured out the phone was set to answer when I 'picked up' the phone. There's a setting for this. Check it, make sure it's not set this way so it doesn't happen again.
Also, my screen is so sensitive that I can hover over something and it will select it. A little more than annoying. A cover helps with overly sensitive screens.
