Why does my iphone w/ ios7 vibrates randomly when unlocked?

Is it possible to be a notification for automatic update apps? Everytime the app update maybe it vibrates...

I had the random vibrate issues too - happened as soon as I changed the mail (Gmail) from push to 15 min refresh. Turned back on push last night and haven't had the issue since.

Agree is mail app, mine was set to off in notifications, but still had vibrate turned on.

Thanks!

For me it wasn't the calendar app! I had my calendar sync with Google calendar and it was pulling information even from calendars I didn't have turned on. I found a non-native calendar app to use, but I never completely disabled the notifications in the original calendar app. When I look at it more carefully I noticed the notifications were still set to vibrate. I change the vibration so it could be something that I would recognize and then scheduled an appointment in the calendar app (shared calendar) to test it. Once I determined it was indeed the calendar app I went back to make sure the notification setting was set to vibrate "none". I have had challenges with the way the calendar integrates with Google for the last six months! I hope this works for some of you.

I don't suppose there is any kind of event log to trouble shoot this?

Irritatingly same issue. The ringer switches from vibrate on and off... back and forth. It's worse when I'm in the middle of typing something and it covers the screen.

Are they going to resolve this?

Go to Settings/Sounds. Go down to Sounds and Vibration Patterns. Each one listed has a different default ringtone and vibration pattern. Click on each one and the first choice is Vibration. Change the ones that you don't want to none for vibration.

Hope that Helps.

I think I might have figured it out for my phone. I too kept getting random vibrations with no notifications of any sort. Although, for me, it doesn't matter if I'm using my phone or if it's locked. It vibrates either way. My location services is off, always is, but I double checked. When I was checking my ringtone under Sounds, I noticed that the New Mail sound was set to Vibrate Only. I never use my email on my phone, but my husband had linked my email to my phone for something awhile ago and never un-linked it. I never had these random vibrations when I first got my phone. So I think this may be my answer. It would also answer why some people get a vibration and a "page turn" (or other) noise. Under Settings, go to your Sounds and see what your New Mail, Sent Mail, Tweet, Facebook, etc are set to. Change them to "None" or unlink the accounts to your phone like I did. I think this might be the answer. At least for me, I hope it is. I will update this later and let you all know if this fixes the random vibration or not! However, this may not be the answer for everybody. There are always bugs with technology. I just hope this bug can be squashed! Good luck!

I was able to resolve this issue on my phone, and I believe that there's a bug in iOS.

On my Notification Centre home screen Mail and Calendar both said that they weren't included in the notification centre, or had no sounds enabled, but when I went into them they had sounds and vibrations enabled.

I'd recommend going into the notification settings for all apps that ship with the phone such as:

Phone, Messages, Reminders, Photos, Game Center, Mail, FaceTime, App Store, Calendar, Podcasts

regardless of what the Notification Centre home screen tells you to check their sound settings.

Go into Settings > Notifications and tap every app under INCLUDE to check for Sound only notifications.Go under the DO NOT INCLUDE section and tap every app to check for Sound only notifications as well as to turn off the Allow Notifications toggle.

Had the same problem, turned out (I'm pretty sure, time will tell) to be calendar notifications. I have sound turned on for Calendar in Options -> Notification Center, which is fine because I want alerts and sounds to tell me about upcoming events. But in the Calendar page for notifications at the bottom, there are also settings for "Invitations", "Invitee responses" and "Shared calendar changes" which had sound turned on, but no banners, alerts or "show in notification center."

I have my work email account on my phone, so every meeting request I received, or every response I got to a meeting request I had sent was making the phone chirp. (The emails trigger it, but the setting was under "Calendar" since these are related to meeting on my calendar linked to my email.) Also, I have shared Google calendars with family members, and apparently whenever they changed anything in a calendar, I got a chirp as well. I've off sound for all of these, and we'll see if that makes the problem go away completely.

There really needs to be a better way in iOS to say "Show me everything that can make my phone make a sound" (right now, there are multiple incomplete ways only). Or how about if Siri could answer "Why did my phone just vibrate?"

Mine actually happens every time I put my passcode in too fast and if I only press the numbers and nothing else it's fine but when I tap the screen heaps of times really fast it vibrates!

I have the same problem too, i want to know if there anything to do to stop that
