Volume changes on its own?

You may already be aware of this but the iPhone does remember the difference between the volume you set for headphones, iPod and the ringer. Thus, you can have a different volume set and not realize it. It maybe something worth looking at.

I performed what you described on my own 3G iPhone, setting the sound to a level in settings, then going home and using the side keys to alter it, then checking the sound in the settings, and each time I did it it was exactly to where I had set it with the side keys. So I'm unable to reproduce your problem, which makes me wonder if it's a "just a bug in the firmware." That's why I'd recommend attempting whatever trouble-shooting techniques that are available to you.

mine does the same thing and when i get text i get no sound what the **** is wrong with these phones

Alex, read this thread, hopefully it helps. http://discussions.apple.com/message.jspa?messageID=7588685

If you or anyone else gets this fixed by doing the "restore as a new phone" and then syncing let us know. I'm hesitant to try this yet since both my 3g and my wife's original updated iphone are doing this. With the original one it had been mine and we set it up as a new phone with new sim for her and subsequent to that I did a restore on it for another issue and it still has the volume issue. I'm skeptical that the restore as a new phone will work but if anyone sees a definite cure I'll try it.

Has anyone yet been able to correct this either by a restore or any other method?

nope got a new phone today 2nd 3g and same thing idk but this really isnt goood and my texting sound doesnt work we need a fix! now!

For anyone who is considering doing the "restore as new phone" rather than from a backup don't, it's a major pain to set your phone back up the way you had it previously. I did it just to see if there would be a change, there wasn't. The volume slider still changes on its own randomly. It will always do it after you make or take a call. I wish I hadn't gone to all the trouble of the restore, looks as if we'll just have to wait for a software fix.

Yeah mine does the same thing. I went to the apple store and they neded up giving me a new phone, and this new one does the same thing. Should I just return this phone all together or do you think that a software update will fix this issue. My friends iphone 3g does not have this problem.

I have had other brand phones in the past that do the same thing, when you put max volume on it will let you use it like that for that call but then take it down to what is considered safe. I also have an office phone that does the same thing. It is a mechanism to support the manufacturer of the product so when you sue them for the volume being so loud it can damage your eardrums they can say that you chose that and that the equipment returns to a safe level and you decided to increase it yourself.

I am pretty sure this is the real reason for this.

Well, my G3~16GB doesn't appear to have this issue either, although I would really recommend that you take a look-see at the link that was posted by "Cleule".

Hmmm...is the volume actually changing?
I have a first gen with 2.0 update. I set the ringer at 12 clicks up using the side buttons. When I check the settings, the slider is way down. So...I select my ring tone to listen, and the volume is fine. Return to the slider, and now it's up where it should be. Looks to me like a problem with the way the slider is displayed....the volume really hasn't changed.
Anyone?
