ive tired to reset my phone, i have a smasung glalaxy s3 and i dont know the reset code. can anyone tell me what to do?
if your Samsung galaxy s3 is not working of any of this test code sad to say you phone is a clone..haha
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.

Nice post.I think it is very helpful for me and other. Thanks for great post.
Thank You sir we are trying oue best to provide you useful information
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
mine is working with some of the codes except for the battery and the service mode

You can always check mah rating printed on your battery

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
Yes It is
None of the codes work on my iphone ..
bettery stauts code give me
Maybe Because they are for Samsung galaxy S3
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)
