    My accelerometer is tilted. If I place it on a flat surface, and load up cube runner, the ship starts moving to the left. My old iphone played the game fine... what gives?

    Mine got "fixed" alone with the new firmware the secret one, it does exactly the same as your does. Cuberunner goes a little to the left, so i have to hold it a little to the right, but its just a little, i tell everyone its 85% fixed hehehe.

    I can do anything on the iphone go into landscape or portrait and has been working for 2 days so i think its okay, i will wait for a firmware upgrade to see if that fixes the problem, seeing that 2 or 3 people have the EXACT same problem as i do makes me wonder how many people have this problem and havent even notice because if you dont play games you wont notice right?

    So maybe a lot of people have a broken iphone and havent noticed or dont come to mb to post.

    Can anyone who exchanged their iPhone say definitively that the replacement iPhone's accelerometer works without issue? And what model did you exchange?

    I guess I am hoping to narrow down whether this is a software or hardware issue. I got my iPhone on the 11th, and I upgraded it to build 5A347 but I am still experiencing issues. For those who are trying to find similarities, I have the 16GB Black iPhone 3G.

    I had the accelerometer problem on my original black 16g & have not had any problem with the replacement. The replacement (also black 16g) had 345 & I've updated to 347 -- have not seen an difference in Accelerometer behavior.

    For those near Apple stores, note that they have replacement stock in plan boxes (new hardware just not in retail pkg) -- do NOT go by the iPhone availabilty widget on apple.com. Call AppleCare (in US, 1-800-my-iPhone) to report the problem & request replacement. They'll want to walk you thru doing reset & restore, because I'd just performed these steps before calling, they deferred these steps & made appt for me at nearby apple store genius bar. Genus bar checked out phone for about 5 minutes then began replacement process. I was in & out in 15 minutes.

    They may iniially recommend repair, but didn't hassle me when I said I wanted replacement instead.

    Thanks for your advise. Based on it, I went ahead and made an appointment with my local genius bar although the inventory tool says out of stock. I also needed to make an exchange at the time. For one employee, my accelerometer worked fine.

    For the genius, it broke reliably, thankfully. He did a restore even though I showed him it already had 5A347, but I can understand them not wanting to waste phones if possible. After the restore, it broke immediately. He had no problem replacing it after that (though he did admit it was the first one he'd seen with that problem).

    So far my new phone has been working fine. It was shrink wrapped in box and I took it home that way. Interestingly, the new phone had 5A347 on it already.

    I'll come back and report if I have issues with this accelerometer. Otherwise, you can consider me another of this thread who've had no problems with their replacement.

    sorry...new to iphone. how does one check fi they have 345 or 347?

    To be honest I do not know exactly what is wrong w/ my iPhone...
    the accelerometer actually works occasionally.. which annoys me. For example in calculator it tilts totally perfect... safari works half the time.. and ipod mode works half the time too. games seem to wkr fine tho as well....

    i'm assuming this is firmware.. and not a physical defect. i can't see how a new iphone would change a firmware problem.. in fact shouldn't everyone have this problem but maybe not realize it?
  • Cleverhobbit Level 1 Level 1 (0 points)
    well, I got the replacement from the genius bar at the local apple store (firmware version 45) yesterday. The phone accelerometer work just fine.
  • danperth Level 1 Level 1 (0 points)
    The "screen doesn't rotate after sleeping" bug does seem to occur mostly on the black 16GB (mine has firmware 5A347).

    I suspect it's a very slight hardware difference that is causing the problem. ie, perhaps a slight timing issue with our devices causes the wrong state to be restored after a sleep. Given that the accelerometer itself works perfectly if it never sleeps, the accel hardware is fine, but the logic that saves/restores its state is not quite right.

    I believe a firmware fix can make the restore process a bit more robust - ie, whatever they do to initialize the accelerometer correctly after a reset, they should just do that again when waking from sleep!
  • alextn Level 1 Level 1 (0 points)
    also just to reconfirm... i do have a black 16gb one. seems that no one has reported this problem w/ the white one?

    how do u check the firmware?
  • danperth Level 1 Level 1 (0 points)
    Go to Settings -> General -> About

    Look for:

    Version 2.0 (5A347)

    Yeah, weird that no white ones are reported to have the problem. Maybe that's just because the black's so popular..
  • alextn Level 1 Level 1 (0 points)
    thx damperth...
    so i checked... i too am using Version 2.0 (5A347).. new from the store.

    hoenstly i think that all people have this rotation problem. when i first got this phone i didn't have it either... only started a few days in. so we'll c if any of the new ones replaced will start having symptoms....
  • Ian Glazer Level 1 Level 1 (5 points)
    I've got a white 3G that has this problem. Looks like I've got the 45 firmware. Does it make sense to try the 47?
  • signat Level 1 Level 1 (0 points)
    I thought I would share the rest of my story:

    Based on the advise of this forum I also exchanged my phone (16GB Black) at the apple store...my accelerometer was working when I went in, and I was praying it would stop before I got to the Genius Bar...thankfully it did, and they replaced without question.

    My replacement phone already had 5A347 on it, but I don't think it mattered because I upgrade my original phone to 47 and it did not resolve the acc. issue. However, I am happy to report that my new phone is not experiencing the problem.

    I asked both the Apple Care rep I talked to as well as the Geniuses if they had any other reports of the issue, and they said no. I told them that there is a rapidly growing number of users reporting the issue on their support site. So, either we are a very small majority of iPhone owners who bought defective hardware, or Apple is just trying to keep a lid on some of the bugs of the new 2.0 software (or specific build).

    The guy I had on the phone from Apple Europe also said they never heard of the issue.

    I know many people who have an iPhone (8GB) and don't have any accelerometer problem. No one knows (except Apple I hope)if this is a hardware or software issue. They should communicate about that to prevent people like me from taking their iPhone back to the store and wait for a month before getting a new one! (I'm in Belgium)
  • andyd2k Level 1 Level 1 (0 points)
    So for those that got it replaced, have you experience the same issues since then?
