Q: Usually my App Store works but today I cannot download anything. I've tried factory reset and also deleted some photos and other apps on my phone. Still won't let me download Netflix app

Hi,

It's possible your iPhone needs to update to the latest iOS version. Instructions here >  Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support

Then try downloading the Netflix app.

BTW, Netflix requires an iOS device running 8.0 or later > https://itunes.apple.com/us/app/netflix/id363590051?mt=8

Try resetting the App Store:

Close the App Store completely from the app switcher window by double clicking the Home button and swiping up the App Store preview pane until it disappears from the screen. Then sign out of the iTunes Store (in Settings).

Then restart the device.

Then sign back into the iTunes Store and try downloading again.

Also check Settings > General > Restrictions > and make sure that the iTunes Store, Installing Apps, Deleting Apps, and In-App Purchases are all under the Allow section.
