Samsung Galaxy S4 SIM error/constant reboot issues
A couple mongths ago my Samsung Galaxy S4 started giving me problems with dropped calls/no sound/no service and feeling warmer than usual. I didn't think anything of it since I figured it was most like due to nextwork issues. Now that the phone is out of warrant by 2 months I am getting an error telling me that the SIM card is not detected and forces me to restart the phone, rendering the phone useless.
I took the phone into an AT&T store and they replaced the sim card. The problem occured again within an hour. I took the phone to another store and was told I should perform a factory restore. I did this and the sim problem continued. I googled the problem and found that several other people have been having this problem for some time and have posted various solutions. I have tried the following with no luck:
1. Replaced sim card - error continues
2. Factory restore - error continues
3. Boot into safe mode and clear cache - error continues
4. Cut a piece of paper to the size of sim card and insert into sim slot w/sim card - error cont...
I called AT&T support as was told the phone is out of warranty and it would cost me $150.00 for an insurance replacement (i have insurance for the phone). I am not convinced that I should have to pay for this repair due to the fact that the phone has been giving me problems for some time.
Can anyone help me in getting this phone repaired/replaced in warranty? I am very unhappy with the level of service I am currently getting from AT&T and after many years of being a subscriber am seriously considering another carrier, preferraby one that does not charge a deductable for insurance replacements.
