Iphone5s update ios 10 version, ok?

Very good. Mine is 10, which is very smooth and humanized. IOS 10 must be the last system upgrade of 5S, and the future system will definitely not move 5S. However, after the upgrade experience of netizens, I feel that after upgrading iOS 10 beat 1 in 5s, the fluency is not bad, and there is no jam. It's just that software is easy to flash back. After all, it is the iOS 10 experience version. After the official version comes out, I believe that iPhone5S users have no pressure to use iOS 10 system.
