My Samsung Galaxy S4 recently started displaying an error saying
SIM card removed. Unable to detect your SIM card. Your device will restart to check for your SIM card.
There is nothing to do at that point than reboot, which is irritating of course. So, I thought it might be a hardware issue, so I used my insurance to get a replacement, which was of course a refurb.
This one came with a whole host of problems, including the accelerometer, gyroscope, and light meter not working. It would also randomly lose signal in places I know it should not.
So I got yet another replacement, and this one works fine, except it would do both the dropping signal and rebooting with the same message. So this time I replaced the SIM card, and it made no difference.
So, SIM card error. I've replaced the device itself and the card, yet the problem persists. The only things I can think of are maybe this replacement just happens to have the exact problem my first one did, or that there is a software issue (since software is the only common element that was never replaced), but I haven't installed anything new or upgraded Android recently.
Any ideas or should I go for #4?
- Phone not detecting SIM
- Replace phone with insurance refurb
- Refurb has a ton of issues
- Get a second refurb, this one works fine except it still has the SIM card errors and also drops signal sometimes
- Replaced the actual SIM card, no effect.
In case it matters at all, AT&T.
