I see this is a common error on the S3, but I haven't found anything about it on the S4. Is anyone one else getting it? Basically, it says that the SIM card has been removed when it hasn't. When it first started happening, a reboot worked. That was in really spotty coverage, so I attributed it to that. But today, it has been constantly doing it. I think a few minutes ago made the fifth or sixth time today, and then after a reboot, it went right back to it. A lot of people said to take a thin strip of paper and put it on the label side of the SIM. And that will make it keep good contact with the connectors. So far, so good. But it hasn't even been 20 minutes since that. Has anyone else experienced this? I haven't updated yet-- I keep delaying it. Does the update address this? I have attached a screenshot.
