    Heres how its done:

    Step 1: Dial *3001#12345#* on your iPhone then press Call.

    Step 2: You'll now enter Field Test mode. You'll notice a signal strength indicator on the upper left hand corner of your screen. You can toggle between signal strength bars and a number by simply taping on it. At this point, press the home button to exit the app or if you would like the feature to be permanent, continue on. Don't worry, the process is completely reversible.

    Step 3: Hold down on the Power button until you see the slide to power off' bar. Do not power off the device.

    Step 4: Press down on the Home button until the app closes and you return to your home screen. (NOTE: User bladepwns reports that on iOS 7, this does not return you to the home screen. He reports that powering OFF your phone while in FIELD TEST mode will accomplish the same thing.)

    That's it. Even when restarting the iPhone, the signal strength can be toggled between bars and numbers. The closer your number is to zero, the stronger your signal is.

    The lower your number, the stronger your signalbut don't include the - sign when evaluating (so, if the signal says -60, that's better than -90).

    To return to the default bars permanently, follow these steps:

    Step 1: Dial *3001#12345#* on your iPhone then press Call.

    Step 2: Press on your Home Button once.

    This trick may come in handy when you're in a dead zone and need to know where to move to for a better signal.
    Did this today on my 5S & it works perfectly...Thanks for the tip!!

    I am noticing that whenever I'm in the Tapatalk Pro app, the default signal bars display. While viewing the home screens or when I'm in any other app, the dB status displays. Anyone else seeing the same thing?

    I've noticed if I tap the signal area when some apps are open, it will change between the numbers and dots. It seems it has to be an app that doesn't have an action button right below the signal area. And it will remember how the display was if it was different from 'normal' when you close it, and it will display the same way the next time you open it.

    Monitoring my signal throughout the day to put together a lil chart showing how dots correspond to signal in dBm on my Verizon iPhone 5! May not help anyone else but it'll sure help me!

    The only thing is I don't know if my ranges will differ based on whether I'm on LTE or 3G...

    This is what I have thus far...

    Dots: dBm

    LTE
    5: 69-82
    4: 87-93
    3: 95-106
    2: 107-
    1:

    3G
    5:
    4:
    3: 88-92
    2: 93-100
    1: 102-106

    That graph won't work for me. I have sprint but at my home I get 1-2 dots and I just did this (had to power cycle in test mode to get it to stick) and I am between -117 to -114.

    Yeah I don't know how it'll work because I'll be on 2 dots and get a reading then later that same reading will display while on three dots. One thing I've see is what range is considered decent signal for wherever I am and that in and of itself is very helpful.

    If you tap on the area of the signal, it will toggle between the numbers and the signal dots.

    I used do this on my Nokia 6690 in the 90s. The best signal I saw was -52 db at the base of a tower. The cut off to no signal was -113 db. This is the actual strength of the signal getting to your phone For most young people, in the audible frequencies, the hearing threshold is 0 db. Every 3 db, sound, or in this case, signal strength doubles. I will keep my phone in field test mode and see what I get these days.

    I used to do this on my Blackberry's with the key-press they had. I don't know how do it currently on their phones, but there is someway, that I hope was posted on their forum. I am going to go back and forth between dots and decibels when I need to.

    There is a step by step on how to do this in the guide section. Its can be quite helpful at times to have an actual readout on your phone.

    Anyone know if there is something different to do with this to get it to stick with iOS 8? Trying it on my 6 Plus and just goes away when I exit the field test app. Even powering off and on in the field test app as well.
