Let's say you dropped your iPhone 6s and it broke. Next, you head to the store for a replacement iPhone 6s and are tasked with the process of transferring all of your information over to the new phone.
The process is simple, or so it seems. You need to sign into your iCloud account and restore the data from your iCloud Backup. This way, you can keep your contacts lists, your photos, messages and everything else you keep stored on your phone.
Restoring your last iCloud backup should do the trick, except some iPhone users are reporting that they have lost data when they attempted to transfer their data to their replacement phones.
Lost data includes Messages and Recent Calls data, even Health statistics and Safari browsing data. Other problems include crashing apps, disabled notifications and missing photos.
The cause unknown for now, but some have suggested the problem stems from a glitch associated with updating the OS from 9.0 to 9.0.1.
Apple hasn't yet found a solution for the glitch, but is currently working on the problem. According to Apple Insider, some users on Apple forums have recommended making sure that the new and/or original phones are updated to iOS 9.1 and performing a new backup before transferring data.
