The difference between the new iPhone 6s and the iPhone 5, 5s, or 5c isn’t just its display size. It’s also its display resolution in which the iPhone 6s sports a higher compared to its predecessors. That being said according to user reports, there are some users who are encountering a weird display bug when restoring their iPhone 5/5s/5c backups on their new iPhone 6s.
As you can see in the screenshot above, for some reason the displays on the iPhone 6s has been zoomed in, and not in the regular way. This has been zoomed in where the sides of the display has been cut of, kind of like the content was not optimized for the display/resolution of the iPhone 6s.
This bug seems to mainly affect native apps like Wallet, Weather, Watch, Calculator, and Health apps. It has been advised that doing a clean install of iOS 9 on the iPhone 6s will resolve this issue, but if that was the case, restoring from backup would have been kind of a waste, right? Some users are reporting that turning on Display Zoom in the settings will fix it, but this also means that it will result in the entire phone featuring a zoomed in look.
According to some who have the iOS 9.1 beta, they claim that this has been resolved in the beta so we guess we will have to wait until then to get the fix, or hopefully Apple will release a fix for it before iOS 9.1.
