    Default A Few Hardware Issues...

    I've noticed a few issues with my iPhone. This is my second one, and I'm wondering if this is due to my case, how I use the phone, etc. If anyone could offer any insight, it'd be much appreciated:

    1) Phone screen won't light up again after cellphone use
    When I put the phone to my ear, it correctly darkens the screen. However, when I'm done, I note that it sometimes will not light up again, and I have to use the "action" button to bring the screen back, then switch to the phone app, then end the call. I do have a silicon case - does anyone know if somehow the case could be interfering with whatever sensor switches the screen on and off?

    2) Landscape switch
    I've also noticed that the phone will have trouble recognizing that it should switch between landscape and portrait modes. This happens in both Safari and iPod, and most often it happens that the phone gets "stuck" in landscape mode, requiring a trip to springboard to switch back.

    3) Hot & Unresponsive Screen
    I *think* I figured out why this happened, but just wondering if anyone else has seen this: The other day, my wife was driving me to work and I was checking my mail - it was a very sunny day. My phone stopped responding to touch, and I noticed the screen became very hot. I immediately switched it off, and it rapidly cooled. As soon as I turned it back on, it began heating up again and was unresponsive. When I arrived at my office, I tried again, and this time the phone stayed cool and worked fine.
    I believe that this was due to the fact that "auto-brightness" was set on by default on the replacement phone and I had never turned it off. Because it was in direct sunlight, it was trying desperately to brighten the screen enough to compete with the sunlight, and this was the cause of the heat, which in turn made the touch recognition fail (does it work partly by recognizing heat differentials?). Once I turned off the auto-brightness, it seems to work fine, even in direct sunlight.
    I mention this because it seems like a serious bug - it definitely got hot enough to do damage to the phone if it had continued. I hope I'm right as to the cause - I certainly haven't seen it recur.

    HI, in case you have not noticed the iphone has a few bugs quite a few in fact, here is a list so far with my iphone to help you out, so do not panic we all have these problems some more some less.

    1. Yes you are right the back and fourth landscape is messed up completely when switching between them in all aspects ipod albums, pics and browser mode, it does not flip back all the time you kind of have to force it a few times, so don't count on it to work flawlessly.

    2. The iphone heats up big time, NOTHING TO DO WITH THE SUN!!!!!! it has a chip inside it a processer which heats up quite fast and since the back of iphone is alumuinm it creates even more heat, there is nothing you could do about it, it is built that waybecause there is no fan inside to cool it off. I have used the iphone non stop for 5 hours it got very hot but, it never power off or froze on me.

    3. battery indicator does not always work properly too , you can charge it all night and it will not budge, but phone is charged.


    hope this helped you.

    OK, good to know it's not just me. I realize there's no way to know the answer to this, but I wonder if this is an issue fixable in software. Sure as shit hope so, cause while I realize this is a 1st gen product, it still cost six hundred mf'ing dollars.

    No, this was very different. I've seen the same heatup under heavy use, and believe me - this was something totally different. I bought the iPhone on opening weekend, and I've not seen anything like this before, nor since. Then again, I haven't really pressed my luck. And, heh, thanks for the explanation on the processor, but I'm aware of that. Interesting to note though that the ARM processor in the iPhone doesn't ever really run that hot, even at max speed (Presumably it does some stepping)

    Yeah, I forgot to mention that. I just saw the same problem tonight, although in my case, it's not so much a battery level indicator as it not recognizing the charger at all. Generally, plugging it into my computer is the only way to get it to charge. This has happened before with a different phone and several different chargers. I'm pretty certain this, at least, is solvable in software, although I had hoped that the 1.0.1 update would have dealt with it.

    There seems to be a problem with the touchscreen of the iPod, apparently some of them fail to work properly after a couple of weeks of usage. According to a source, Apple is aware of this problem and exchanges the affected iPhones on warranty but for somebody who doesn't live in the US, this would be a very difficult task I'm afraid.

    1. This is a known bug and apparently has been improved in FW 1.0.2.

    2. It isn't switching because you might be holding it parallel to the floor. If you hold it more perpendicular to the floor it switches without a hitch, which makes sense because the sensor isn't designed to work on a flat plane. (think, a drop of water wont roll down on a plate if you are holding it parallel to the ground.

    3. One time I had WIFI on when I first got the phone, and the battery drained in about 20 mins and the phone got super hot... too hot to touch almost. I turned it off, waited for it to cool down, then gave it a full charge and nothing like that has happened since. It does get warm to the touch when using WIFI though.
