How to get all my apps and photos back on my iPhone?

My phone crashed after I tried to update it and I took it to a store to get it fixed and when they fixed it I lost all my apps and photos but in settings and on my storage it says everything is there. On iCloud nothing is there when I back it up. How can I get it all back?

Restore from backup on iTunes and maybe iCloud again. NOTE: anything you haven't backed up to iCloud in your settings or in iTunes recently might be lost forever. Best luck.

You can always go to the app store and see "purchased apps not on phone" there you'll find all the apps you have downloaded
