Turn Off Field Test Mode

You can quit Field Test mode by going to Phone then typing in *3001#12345#* then call while in the Field Test Menu hold down your power button then when the slider appears DO NOT SLIDE IT hold down the home button until the home screen appears you are now out of Field Test Mode fully!

I know I am a few years late but I had this problem on my phone and I fixed it.

I activated FTM on iPhone 4 iOS 5.1 and upgraded to iOS 6 and couldn't turn it off .. So this is what I did..

DO NOT DIAL THE CODE MANUALLY. Open "Notes" and create a new note, type *3001#12345#*, then copy it.

Open Phone, dialpad and PASTE the code then press CALL. Once you enter Field Test Mode, press the db to return back to signal bars and press and release (do not hold) the Home button.

This fixes this bloody problem once and for all.

Cheers!

Please tell me how on 3.1.2 ( Factory Unlocked ) to keep DBm not Bar for signnal after exiting Fielt Test Mode . Thank you.

This worked for me:

- Get in to Field Test (call *3001#12345#*)

- Tap the signal strength number so you get the dots back

- Hold down the power button and when the slider appears, just slide it to power your iPhone off

- Turn your iPhone back on, and it should be showing the dots

When you're in field test mode, you hold the power key until the "Slide to Power Off" shows up. Now hold the home button until it resprings. You will now ALWAYS have the dB meter, even through updates. The only way to remove it is to restore as a new phone.

If you get an upgraded phone model and restore it with a backup from one of these phones that have the dB meter, you will transfer the dB meter to it.

Hi

From my own experience to go back from dB signal strength to bars follow these steps:

1. Dial *3001#12345#* and hit call.

2. Field test mode opens then toggle signal strength from dB to bars.

3. Just press the home button long enough so that it automatically takes you to the home screen.

And voilà , appear the beautiful bars. 😀

Apple is removing my email, so let's discuss this here.

1. Log out of apple on the iPhone

2 Try a cold reboot. Hold home and sleep simul until the silver apple appears then release. Wait until the phone reboots

3. Try the procedure again

4. If successfull, log back into apple on the iPhone

I have an idea.. Backup your phone to iTunes and then erase all settings, do a full reset. Once the phone is done, try the procedure. If it works, go ahead and restore.

If it does not work, download a fresh copy of iOS 7.0.4 and install it, then try. If successfull, do a restore.

Remember this is more likely an iOS glitch and nothing to do with the ID or backup.

If it doesn't work and if you are under the Apple warranty (you probably are), go to an Apple store and swap the phone for another one. Let me know!!

Yeap mate I did exactly what you've said.. Wrote down in notes, copy and paste them, and then called, once ı2ve entered the field test mode I tabbed on the dbs to change them into bars, and tabbed once (shortly) on the home button, as I turned on main screen, I saw the operator bars but the wi-fi dbs.. 😟

You're not bothering me. Let's try this again.

You opened notes and copied the code? You opened phone, dialpad and pasted the code? Pressed call and entered... FTM

Once you entered FTM mode, you touch the db on top and they turn to bars, right? Then you pressed and released (did not hold) the home button? This all did not work?

If it didn't work, I don't think the issue is the apple ID, I think it may be a glitch in the iOS itself.

This cleared it for me, thanks!

Only had to reset some settings/prefs.
