Hey guys. Im having the same issue here. Running iOS 7.0.4 (since it was released) and just a couple of days ago i also got that error. What?!
My phone is a black iP5 32GB and it's running iOS 7.0.4 and the phone IS NOT jailbroken. I'm using the original Apple cable that came with the phone. The phone was NEW when i bought it.
I cleaned the lightning port on the phone and still get the error. Many say that dirt gather there and so on but no, that's not the issue here.
The phone never fell on the ground. No kind of damage or anything. I am very delicate with it and specially with the lightning cable and i never plug/unplug it in any bad manner or so. I always grab it by the plastic connector and do it carefully.
Can anyone here give me atleast a clue on what's going on? I am a 100% LEGITIMATE user and this thing really started to bother me now. I have no clue why this wasn't happening before while i was running iOS 7.0 and then 7.0.2 and 7.0.3. It just started happening since 7.0.4.
What's even more wired is that the error didn't show up untill a couple of days ago (1st of JAN 2014 i guess). I'm running 7.0.4 sice its been released "last year" and had NO problems (except the slow animations which Apple is taking care of now in the new 7.1 beta 1 and beta 2. I'm patiently waiting for the GM release of 7.1 in March or so they say - hoping it will also adress this problem)
I know Apple started to tear down the fake lightning cables but c'mon Apple, i AM using YOUR cable. I also read that someone has at home 8 lightning cables made by Apple (he has a big family i guess) and he has the same issue with all 8 cables. It just can't be that all of them are broken down right?
People having common sense including me are going in the direction that this is just a software glitch/bug in the iOS 7 itself?! Can anyone here confirm this?? Some here have problems with this message poping up even if the phone is not connected to anything. It has to be a software bug!
What's going on here? Any ideas?
Cheers from Slovenia,
