Q: Why isn't iOS 9 under my software update in settings ?

Hi there cheya123,

It sounds like you are trying to update to iOS 9 but for some reason when you go to Settings > General > Software update it just tells you you are up to date. I would start by quitting the Settings app on your phone:

Force an app to close in iOS

1. Press the Home button two times quickly. You'll see small previews of your recently used apps.
2. Swipe left to find the app you want to close.
3. Swipe up on the app's preview to close it.

 
When you have done that restart the device and test the issue again:

iOS: Turning off and on (restarting) and resetting
 

If the issue persists then you can either try another Wi-Fi network, or use iTunes to update your phone:

Update the iOS software on your iPhone, iPad, or iPod touch

If you can’t update wirelessly, you can update with iTunes. If your computer uses the Personal Hotspot on the iOS device that you’re updating, connect your computer to a different network.

1.  Install the latest version of iTunes on your computer.
2. Connect your device to your computer.
3. Open iTunes and select your device.
4. Click Summary, then click Check for Update. 
   
5. Click Download and Update.
