I have no one blocked. I just assumed I was not by phone or didn't hear it ring when calls were coming through. My husband called and it went straight to voicemail. I checked and his number isn't blocked. He was the one who alerted me to the problem.
I have the new Galaxy a20 and I'm Haven the same issues now. I only had the phone maybe two months now and it freezes and all kinds of problems.. I hate this phone. Wurst phone I have ever had.
