New iPhone 4S unresponsive, requiring a hard reset on several occasions

Three times since I unwrapped my new iPhone 4s on Friday (three days ago), I've found that my iPhone was unresponsive: pressing either the Sleep/Wake or Home buttons did nothing, alarms didn't go off, the back was warm to the touch as if it was running something intense. It was necessary for me to hold down both buttons for awhile to force a reset - the Apple logo appeared and the phone rebooted.


Once it was running again, everything seemed normal.


I can't see what was happening before the reset, since the reset seems to clear the system logs (visible in System Status and other apps). It feels like some software is getting stuck in a loop and locking up the entire device.


Is anybody else having a similar problem? If I let this go on for too long, the heat generated would run the battery right down to zero. But this isn't the battery consumption problem written about in other posts - this is essentially an unresponsive iPhone 4S problem.


Thoughts?

Same issue for me. It seems random when the phone becomes unresponsive. I'll lock the screen as usual, come back to it after 30 minutes and home button or lock buttons dont help. Hard reset fixes the issue (Holding both lock and home buttons for 30 seconds). I saw the iPhone4S auto sends diagnostics info so hopefully Apple is already working on an iOS release to fix these bugs. I just opened a support case and I'll call later today.

I had my phone replaced and I no longer experience this problem.


My previous 64GB iPhone 4S was shutting off and requiring a hard reset about 1-2x a day with moderate use, and reporting panic.plist and resetcount.plist in the diagnostic logs.


Getting to where I am now (a phone that functions properly) was a withering process. I had two resets done, three trips to the genius bar, my share of smirks from employees there assuring me that the phone was fine, and finally a reluctant replacement.


Apple's phone support told me the issue was hardware and needed a replacement, while the employees on site at the genius bar told me it was a "software issue" and this was a known bug, and so on, that they were working to fix. One employee told me the phone might need to be restored to factory 4 or 5 times to get it working and clear all the corrupt data.


None of my friends with 4Ses have this problem, and with the new phone I was able to restore from my old backup and it still works without problem or shut down.


Whether or not the corrupt data theory is true as the genius bar employee asserted, or whether it was hardware like the phone reps said, the bottom line is I received a replacement phone and it's no longer an issue.

There are so many issue that could cause the iPhone 4S to goes wrong. iOS bug, third party apps bug, some of the settings that we have change cause it to not function the way we want it to be. Sometimes a restart of the phone can solve the problem and sometimes all you have to do is force certain app to quit. A hard reset or restore is our last resort if all else failed. Just read this see if it helps iPhone 4S hard reset.

Add a 4s 16gb to the ever growing list.. my AT&T phone is locking up and this morning after charging all night it came on and said battery was 48%.. I used it for a little while surfing the net and just thought it didnt charge. it never moved off 48% so I did a hard reset and it came back on to 90%. I am also experiencing the "black screen of death" going to call apple in a little while when i have a second phone handy.

Here's the deal. The Apple products are fabricated in mass without a real test on the product as a whole. There is obviously something wrong with the hardware that apple refuses to fix. Or at least, they refuse to fix at the factory level. Mine was not a software issue of any kind. The technician wiped my phone twice in as many days. Once we reloaded from the backed up copy of all of the same stuff that was on the phone and once to an empty phone. Both times the phone was wiped by the so called genius and reloaded everything including the IOS. When the phone kept shutting down, while in sleep mode, I went back to the not-so-genius. They gave me a refurbished phone. I believe the refurbished phones are better because they would be checked out better by a real technician. I reloaded the refurb phone with the original backed up software. I have never had a problem since. Not one in the many months. I suggest that those who have phones that lock up while in sleep mode, go in, throw a fit, and upgrade to a refurb. It is worth it.

Just adding another phone to the list to help keep the count going.


Experienced my iPhone 4S turn off by itself while sitting idle with plenty of charge left in the battery on 10/14/2012 (iOS 6.0) - occurred twice in the same day.


And experienced it again on 11/9/2012 (iOS 6.0.1) with a 100% charged battery.


On the first occasion, the phone was not plugged in, and on the second occasion, the phone was plugged into my laptop just charging (iTunes was not running).
