iPhone 4 Vibrates For No Reason?

I’ve been noticing over the past few days that my iPhone 4 seems to vibrate very softly, sporadically throughout day.

At first I thought I was crazy. The vibration is barely noticeable and the first few times it happened I simply dismissed it thinking must be going crazy. Luckily I’m not.

Anyone else noticing a very subtle vibration coming from their iPhone 4? I can’t seem to recreate it on command.

I havent really noticed anything out of the ordinary. My phone has been perfect. (including the antenna)

I believe my 3GS does the same. I've often caught myself reaching for it due to a sensed single vibration, only to find no activity.

Happened all the time with my 3G on 4.0, but nothing with my iPhone 4.

I get a vibration on my 3G early sometimes, and then the email notification comes a few minutes later.

It could also be phantom vibration syndrome.

Any idea when Rogers will open up online upgrade sales?

Do you have a mail account set up in the app?

It could be the mail app fetching or pushing the new mail to your device. I know sometimes I get a random vibrate when using the phone or when im not using it and when i check for notifications there are none (but the mail app shows more mail in the badge)

I think I may be having this same issue as well, but haven't been paying super close attention to it, as I thought I was crazy. Now i know others are having the same issue, I'll be more viligant, and if this continues, I may contact Apple.

I thought it was the shape or material of the back of the phone letting it glide on equally smooth surfaces. Or that it was vibration from my laptop's hard drive which caused it to slide off the laptop on onto the floor.

Wow that's so weird!
I don't have the same problem.

My 3GS does this, for sure! Occasionally it will vibrate quickly 3 times, then pause for a minute, then go 3 again. Don't know what it is! Maybe JB?

anyone have a problem that when they take a pic with the front facing camera and mms it, the recipient receives it sideways?

Is it on charge when it happens?

I've discovered that my 4G doesn't play nice with some of my chargers I used with my 3G, often kicking on and off charge, presumably while the charger overloads (and kicks off momentarily) or the iPhone itself gets cranky about not getting as much power as it wants and does a cycle of some sort.

When this occurs, it vibrates and I get the “charger connected' chime. If it was muted, I'm suspecting this would only be a vibration.

Like the iPad, I'm wondering if the iP4 is not adhering fully to USB power standards and is asking for more then some devices can offer.

Similarly, I sometimes will get a mail notification and in the meantime my computer decides the message is spam and deletes it from my inbox. By the time I look at my phone, Mail is back to reporting no unread messages.

I haven't notices it when I'm charging it. It just goes off when I'm playing around with it. Today I felt it in my pocket.

What's weird is that it's not the same vibration as a notification or phone call, it's much weaker and longer in duration.

excuse me being off topic here… but is anyone else getting low call volumes? i even did a hard reset (which did fix the problem slightly) but it is still quite low. and yes i took off the plastic film it came with.

any suggestions, or similarities?

YES! This just happened to me yesterday! I also thought I was crazy… I would have bet a million dollars that it did vibrate, but when I checked it, nothing. It only happened to me once so far, but it was really strange.

Robbie Deol

its not specific to iPhone 4… it is something which used to happen on my 3GS. have not noticed on iPhone 4 yet.

I had to return the first Iphone 4 I bought on launch day because the screen started going progressively haywire. It was as if it were possessed by the devil the way the screen would activate and all these unregistered gestures would start popping up programs, apps, txting contacts gibberish, deleting contacts. They replaced the phone with a new one. A defective device I suppose

This is a preference. When you receive a text message or a phone call, you can set it to vibrate several times after a few minutes if you don't read your message or answer the phone.

Unfortunately, it doesn't also show anything on the screen if you already had viewed the screen. There might actually be a bug with this functionality, but if you turn off the setting you might find the vibrating stops.

I can't recall right now how to change it, but it is a preference in the Settings app.

Odd.. I never experienced this issue on my previous iPhones. Maybe I wasn't clear enough in the post.

It doesn't vibrate like when you receive a notification. It is a very subtle vibration. Almost non-existent, which is why I thought I was going crazy the first few times it happened.

Check your preferences. The reminder vibration isn't as long as the original vibration.

I realize this has nothing to do with the above topic but I would just like to say thank you to you and all of the other authors on this website. I've been counting down the days until I get my iPhone 4 for quite awhile now and I've moved up to 9th on the waiting list at my nearest Bell store so I'm really hoping that today's the day for me! And does anyone have any suggestions on which case I should get? Are there many to choose from? I've been looking for some sort of list but I can't seem to find anything. Please email me if you can help me choose a good case that can withstand a few accidental droppings at re*******@*****il.com! Again, I understand how relevant this comment is to the thread BUT, I didn't know where else to say this. Thank you for doing such a great job. Really, thanks.

FRS – “False Ringtone Syndrome”:
The sensation one gets when he/she feels as if his/her cellphone is ringing/vibrating only to look at the cellphone and discover that there is no such ringtone, and the sensation was a false one.

There are not many cases yet out for the iPhone 4, but stay tuned to this blog, because we'll be covering lots of case reviews in the coming months. I'm personally going to become obsessed with protecting my new favorite device 🙂

My 3G just started doing this…since the new iOS 4.01…however I thought mine was due to a hardware problem – the sleep/wake button seems to be very sensitive now and bumping the iPhone causes it to vibrate in my pocket…

Yes, I've been experiencing it the whole day, 5-6 times, vibrating without no reason

I've had the sounds from the phone only come through the ear piece a few times. Only seems to happen when skype is running in the background. Turn skype right off and things go back to normal. Happens to my wife's phone as well. Strange days indeed!

Yes, I thought that I was experiencing what I like to call “phantom ringing” where I think I'm getting a call or a text message while it's in my breast pocket at work.
At least I know I'm not slowly going insane!

Did you just jailbreaked your phone?

I bought a casemate that has tire tracks on the back. It's rubber and it also comes with a plastic screen protector. Not the greatest screen protector, but it'll do until you get your free case from apple. Also install the free case app, because you get a pretty good choice of cases for free. Unfortunently it'll take minimum 4 weeks to arrive, but beggars can't be choosers. Also, bestbuy will install the ZAGG invisibleshield for $10. So you have a pretty good choice of ways to go. Good luck, this phone is absolutely crazy. The screen on it and the camera are so brilliant. Anyways enjoy my friend.

My 3G sometimes turns on by itself. I'll have it in my pocket or I'll pick it up from a table and the lock screen is on. I don't press any buttons either. It happens randomly. Can't do it on command.

could it be one of the apps in the background doing this? one of the things that i noticed about the new iPhone is that ALL of the apps that you open STAY open in the background unless you go into the multi-task manager (whatever it's called) and kill the apps there.
i wish there were a choice of really quitting an app rather than leaving it running in the background. yes, i realize that the app's functionality is very limited when it's in the background but still.
why don't you kill all your apps and see if this still happens?

Even when I take number 2, my phone isn't no where near my groin, it's sitting on the ground in my pant's pocket, I see feel the vibration on my side groin area. It's not the phone.. we're messed up. 🙂

There is a spot on the top left of my 3G (on the black bezel that isn't supposed to be touch-sensitive) where if I touvh it, it vibrates and shows the “ringer off” icon on the screen. It's done this since the iOS4 update (at least, I've only noticed it since then).
