Turn Off Field Test Mode

My iPhone 4 "inherited" the Field Test Mode from my 3GS (that had been upgraded to iOS4) when I brought across my apps from the 3GS. Field Test Mode with iOS4 seems to operate on an app by app basis, rather than being able to set the signal strength bars or the dB reading and staying in the selected mode for all apps until changed.

So, after numerous searches, I can't find a clear, definitive way to turn off or delete Field Test Mode. I've tried to reset network settings and the usual reboot, etc.

I've passed on a total reset because the Field Test capability was passed from by 3GS backup to the iPhone 4.

Anyone have a clue?

iPhone 4, Mac OS X (10.6.4)

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.

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!!

there's something wrong with this machine.. 😟 This is because my unstoppable curiosity (don't know why) for the darkside. I understand that I'm some sort of paying back for what I've done in the past lol.. 🙂 I guess there's nothing wrong with IOS's I've used and still do, that's because of a tiny software (which is not friendly with the original IOS) running in background, in especially spring board's refreshing mechanism..


Anyway there's no word can express my appreciation right now.. I truly and deeply thank you for your kindest interest and for the ideas that u've generated recently.. But as I told you before this appears to be more likely a fate thing to me.. lol.. 🙂


Thank you again Greenmoo, God bless you mate..
