The first is a backup sync to your computer through i Tunes.This process could take several minutes, depending on the last time you backed up.David Casselbury received a degree in general electronics in 2001 and currently serves as the IT supervisor for a large regional library system.
However, if all that sounds like a lot of extra work, there is a way round it.
I wanna upgrade to the latest i OS 5 and wonder if my existing photos and videos at Camera Roll will be still on device. The photos and videos in Camera Roll are not synced with i Tunes - they are, instead, the "raw" photos meant to be synced to the photo-organization tool you use - whether that's a set of folders in your filesystem, or i Photo.
As the i Phone 7, i Phone 6S, i Phone 6, i Pad Pro and i Pad mini 4 running i OS 10/10.1/10.2/10.3 or i OS 9 OS system,if you updated your i Phone to i OS 10 and lost photos/videos by accidentlly,or deleted pictures on i Phone in i OS 10/9 by careless,you also can follow this tutorial to recover lost photos from i Phone with i OS 10.2/10.3 update.
Some people may ask does the Apple software update deleted photos?
If your i Phone, i Pad, i Pod Touch running i OS 8, i OS 7 or older version,it is hard to recover these deleted photos on devices.
But now with i OS 10 or i OS 9, it’s extremely easy to recover the deleted photos.
The good news is that i OS 10/9 allows users recover deleted photos and videos from the “Recently Deleted” folder.
If you found the pictures disappearance on the “Camera Roll”,you can go to “Recently Added” folder or “Recently Deleted” folder in the Photos app to recover all recently deleted photos in i OS 10. Open up the “Photos” app on i Phone and select “Albums” in the lower-right corner. You’ll see two folders appear – “Recently Added” folder and “Recently Deleted” folder. Click and to enter the “Recently Added” folder,you will find all your recently deleted photos from the past 30 days still here. In the upper right corner of the touch screen, click “Select” button,then Select the photos you want to recover.
The i OS 5 upgrade may completely wipe your i Pad/i Phone so you have to do a resync to bring everything back.
But that will only work if you've already backed it up and have sync turned on.
When Apple releases a new version of i OS it's normally a simple process to update it on your i Phone or i Pad.
