HELP!! GT-N5100 wrongly detects SIM card Forced Restart

I have an unrooted, purely stock GT-N5100.
I haven't put in the microSIM in its slot ever. I use it in airplane mode , only with Wi-Fi. But I have a problem where sometimes, it randomly detects that I have put in a SIM card( and it leaves me no option but to restart it). Then sometimes after detecting that, it detects that I have removed the SIM card and I again need to restart it. This gets really annoying and this time, it oscillated between the two cases as can be seen in the video below.

Now I don't have a SIM in the microSIM size, so I am Unable to really check by putting in a SIM card, there is nothing in the SIM slot, I checked by opening the flap.
Should I rush to the Samsung Service center to get it fixed? Any other Suggestions to fix it?

NFC Transfer samsung s4 to htc one x not working

Hi all
I have a problem when trying to transfer files using NFC from samsung galaxy s4 to htc one x. Play store is opened with following text "item not found". When i'm sending anything to s4 it is working without any problem.
Does anyone has any idea why might be the problem? I suppose that since the transfer to s4 works, it should work both ways...
Thanks

[Q] [q] no sim - not registered on network

Hello. I've read many threads like this but didn't find a solution for my problem, so I start a new one, my first thread.
I've bought a Note II (N7100) international version months ago and suddenly I got the message "not registered on network", "no sim", can't access to mobile networks and so on. Further, it is impossible to access to settings>more settings>mobile networks> "INSERT SIM CARD TO ACCESS NETWORK SERVICES". For a better knowledge I found a video on youtube it explains the exact issue I'm suffering.
I got this error when I was on stock rom, so in order to fix it, I thought it was the modem, so I rooted it, installed the criskelo rom v.17 and v 18 and didn't worked. Then I installed the file "modem.tar.md5" and no results. When I try to flash that file trough odin I got a message "removed" and then the phone reboot before the "pass" message.
I have tried my sim card on a S3 and it works, have tried the s3 sim card on my note 2 and it works too. It is like my phone does not match my own sim. When I went to the carrier they tried another sim and it works on my device. I have bought a new sim card and it DOES NOT WORK. I think it's a software issue because the phone worked with other sim cards. It is quite frustrating 'cause I have this issue for about 5 months and no solution come to me. I'm consider the hammer test for my Note II if I don't fix it during this month. Can't sell it, rent, borrow or give away because the phone DOESN'T WORK AS A PHONE.
Please, some kind soul, HELP ME!!!

Sounds like a hardware issue with the SIM card reader in your phone, not making a good contact with the first SIM.
Can't you just get the first SIM replaced?

Indeed, I thought it was the sim reader so I changed it, didnt worked. As I said the phone read some sim cards so I think its not a hardware issue. Please check the vídeo I left. Thank you for your response.

Can't read contacts from my SIM

Hi All,
I'm in the process of replacing my Samsung Galaxy Ace II by a Galaxy S5. As the S5 has a micro SIM I could'nt use the Ace II SIM any more and had to replace it by a new SIM. Should not be a huge problem I thought. However when trying to transfer the contacts from the ACE II SIM, nothing was found any more on the SIM. Checking the SIM in my antique Nokia however showed the contacts are still there. The problem of not finding the contacts on the ACE II has been there earlier. Most of the times it could be solved by rebooting the ACE II. However this time (when I need it the most!) it does not work at all. Further details of the ACE II: GT-I8160P. Original Samsung Android 4.1.2. Kernel 3.0.31 - 1106830.
Does anybody have a suggestion how to retrieve the list of contacts from the old ACE II Sim? Could I do this in one way or another with the good old Nokia?
Regards,
Dave
