OK, so you downloaded 9.0.2, which is what is showing as your Version number (the Version refers to the iOS version that you are currently running).
The upgrades to the 9.x software, (like 9.1, 9.2, etc.) are all designed to improve the general iOS level that you are currently using. So, since you are already running iOS 9.01, it is best to install any and all updates that come out for iOS 9.
I would highly recommend that you do the upgrade (after backing up your device to iCloud, iTunes, or both. Also make sure that all of your photos have been imported to your computer.) Once you have backed up and saved your current data, then go ahead and process the upgrade to 9.2.
Once you have upgraded, see how things are working, and if you continue to have specific problems, post back with details about exactly what it is you are having issues with, what is happening when you have issues, etc.
Best of luck,
