    None of these seem to work, being connected to a network extender could be the problem?

    Or is this supposed to work independent from the network?
    Im running 4.11

    Actually, Due to the fact that many people discovered the codes, the updates that were done on your device by your service provider has restricted access to doing that. For many reasons that people were unlocking there phones and other things. I worked with cellphones for over 4 years, and there is a lot you can do with this codes and when people spread it, it ruins it for everyone. Only some phones can still have the access and not all.

    In the menu, if you press "sensor", at the bottom you'll see that black disc under magnetic sensor, with a line I assume pointing towards north. Under that line is a number (mine is 2, I've seen 3 and 1 in youtube). What is that number? A friend of mine claimed it indicate how many times your device had dropped or impacted but that doesn't make sense to me.

    Yes Nash the black line is definately pointing towards north
    The number represents strenght of magnetic field (1 is lowest and 3 is higest)
    Try rotaing your phone in motion of 8 this will improve your mobile magnetic strength

    I have NTT Docomo S3 phone. Codes aren't working. But I'm sure that this phone is not a clone and it is legit. Any idea?

    I really like this phone but there are pros and cons for smartphones like this. Its just that, in terms of battery, I am more cautious. I want a phone where the battery is next to its priority. Just this recent, I bought new battery (from Amazon which is the Replacement Battery For Samsung Galaxy S3, 2100mAh Li-ion Battery by Procizion (No NFC) for my S3 and due to weird battery problems I've encounter. But as a whole, phones like these are the ones that needs to be given a fair review.

    Clone mobiles are made from cheap hardware and type of problems are common in these mobiles
    Alternatively try different SIM on your mobile

    Hi. You seem pretty knowledgeable on these things, I'm new at this and am not. Ha if you have a few minutes I have a few question. I have a straight talk s3 running 4.1.2 and the codes don't work. Would like to root also. Thank you heathercrawford03@gmail.com

    Hello Heather
    These codes don't need the phone to be rooted (Though some codes dont work in some models)

    But *#0*# is the best code and it run in all devices.

    Can you please tell me that your phone is unlocked or it is of some operator (like T-mobile, verizon etc)
