As weird as this sounds, I think it has something to do wt either an IOS 9 update, or possibly a manufacturing problem in a couple of devices. This is only speculation, and I understand that Apple will take this post down as soon as they see it, but hopefully some users wt the same problem will see it, and also reply. When I updated to IOS 9, I immediately got touch screen problems. I brought my device to the app store, and they swapped it out. Well not exactly, I still had to pay $160 out of pocket, because the device was out of warranty. The device they gave me, was the exact same one, and they told me I had to get the same color. For all I know, it could be the same one. I got home, and decided to download the latest update for the device. Immediately I noticed some lagging touch issues. Nothing terrible, but I had used my previous device for two years, so I could tell they were there. Before going to the app store, I created a backup of my device, in case they determined, in case it had to be replaced. I got home, and tried to use my latest iPod backup. Guess what? When connected to this suppossably new iPod, 'no' backup could be located, either in iTunes or the cloud. I had created several new updates to the cloud several weeks ago, and had made an iTunes backup this morning for safe keeping. Still when I connected this new iPod tonight, and went to saved backups, it claimed there were none. I also checked iCloud, and it also said their were none created. So I am getting pretty upset by now. I decide to reload my music library, & iPhoto library, through iTunes. The music library seems to have gone into my iPod, but not the photo library. I have a rather large photo library, so I didn't want to put in in the cloud. For some weird reason 4 of my photos, out of 100's, did import. There is either something seriously wrong wt this IOS update, or perhaps only wt certain devices. Maybe the ones wt problems are being made improperly, or the IOS designers are rushing to get the software developed. No matter what the problem is, apple will unfortunately be using a whole lot of customers, if they continue working like this.
