This is not reinstalling my apps so far.Holy **** guys this is awesome. It will ask you if you want it to delete apps and then have it reinstall them later. Thats SUPER mega awesome iOS 9 feature. I now see many of my apps that don't really have any data such as geek bench grayed out.
Lol true, I hear that indexing thing since 8.0 and its lags everywhere even on lastest devices. I guess iOS will never be as fluid and responsive as iOS 6 or 7, we'll have to get used to it.Here we go with the indexing thing again lol
Whenever I restored to 8.4 or 8.3, I saw no such sluggishness.
