iPhone Signal Strength Got You Down?
Have you ever been frustrated with your signal strength? Think the signal bars on the upper left-hand corner of your screen mean very little at times? Want to know how the the signal displays showing your connection with your carrier are calculated? There's a little secret we want to share with you. And it only takes a few seconds to show your true signal strength. Three words: Field Test Mode. Sounds ominous right? We weren't too sure at first what it was either. You basically tap in a bunch of numbers (that only a engineer would memorize) and press the Call button and then you're in! The magic keys to press are *3001#12345#* followed by the Call button. Yes include those asterisks and hash signs too.
The signal dots up top-left will be replaced by a number. In this case -82. The number can vary anywhere from -40 to -130, where -40 is a strong signal and the other end is a weak one or non at all.
Ignore the rest and look up to the top-left[/caption] To exit, simply press the Home button and you're back out! Enjoy!
