Not sure about anyone else but I am noticing iOS 4 on my iPhone 4 is acting strange since purchase. Anyone else have some strange things going on? For instance, I was looking at a photo in my photo album and went out to safari and then came back to the photo. No matter where I tapped on the screen, nothing happened. Nada. It was like frozen. I got out again and got back in. Same thing. So I opened the multitask tray and closed everything except safari. I went back in to my photo and all was fine. Email sounds seem to be lagging behind. I get the email, see the email and the notification. 30 seconds later I get the sound - after I read the email. Also emails don't seem to be fetching right. They too seem to be a bit off. Anyone notice that when you dial a number and hit send - previously it would go directly to the calling screen and you would instantly see the buttons for, mute, buttons, hold and such? Now, it takes a second or two before it "fades in". Another issue when making a call, the call will end, but sometimes the phone takes about 15 seconds to actually end. I hit END CALL and press the home button, the green banner pops up up top that states tap to go back to call. Again, very strange. I am also noting that the signal bars ( I am aware of the reception issue and suffer from it) are all over the place. Sometimes with the phone just sitting, it can go from full service down to 1/2 bars. I was at a hospital today. The bars were all over the place there as well. Sitting in the same spot mind you. No bars, 2 bars, full bars, none. I could still make calls oddly enough. Although I did get a VM notice so I missed a called. After I checked and listened to my voice mail, it gave me a notice that it could not connect to visual voice mail. Again, very odd occurrences. Anyone else?
