That doesn't mean you can't use your phone to get stuff done! Read More , you see bars. You’ll see somewhere between one and five bars — one being the weakest and five being the strongest. This is a pretty vague reading, and it doesn’t give you the strongest idea of how strong (or weak), the cellular signal actually is.

First, you’ll need to put your phone into field test mode. To do so, call the following phone number: *3001#12345#* and then — while in the field test menu — hold your phone until Slide to Power Off appears.

Don’t power off your device, though. Instead, hold down the Home button until your home screen pops back up. Now, the top-left corner of your screen will display numbers instead of bars. If you want to change back to bars, just tap the area where the numbers are.

The numbers will range somewhere between -40 and -130, with lower numbers (actually higher, because we’re talking about negative numbers — -40 is closer to 0). The numbers on the far end of that spectrum are nearly impossible to get, as -40 is perfect, and -130 is zeno signal.

Generally, -80 is considered a strong signal (5 bars), and-110 is weak (1 bar).

    I got rid of the numbers by dialing the field test number given and then tapping on a few of the options and then just backing out and my bars came back:)

    I assumed the author meant hold the power button, and that's what I did. field test menu came up, and then held home until back to phone.
    this worked, and I see numbers (-98) or bars (3/5).

    question is, do I need to "undo" this? am I in "field test mode" and things are different?

    thank you, I've been wondering for a while how to get better data for signal strength.

    Dude... check what you are saying... "First, you’ll need to put your phone into field test mode. To do so, call the following phone number: *3001#12345#* and then — while in the field test menu — hold your phone until Slide to Power Off appears."
    What is "Hold the phone"???? and when those numbers are dialed the phone displays a Field test Screen... Stop misleading if you dont know what you are doing....
