What happens when you reinstall an iphone?

I'm having problems with importing photos, if I reinstall my iPhone will I still have the photos and apps and everything?

Reinstalling anything will clear your previous data. You have to backup all your photos before you wipe your phone. You can backup your photos using Wi-Fi transfer apps like SimpleTransfer

  • Will Minecraft save my worlds if I delete and reinstall it? Alright so I use 25pp to sync the minecraft app to my iphone, the app works great, but it crashes regularly sometimes I try to open the app. This morning, my safari tab ( the one on the bottom ) disappeared, so I restarted my iphone and then tried to turn on the minecraft app. IT WON'T OPEN! Will the minecraft app save my worlds if I delete the app on my iphone and 25pp and reinstall it on 25pp?
  • When you get a new iPhone what happens to the stuff you bought? Do the songs and apps carry over on your account, or do you sync it with your computer? I just want to be sure that the things I paid for will carry over before I get a new one.
  • WhatsApp says I have no contacts after reinstall? My WhatsApp was having trouble updating statuses and refreshing my favourites page so I deleted the app and reinstalled it. After I reinstalled it says I have no contacts with WhatsApp, and it just gives me the oppurtunity to invite them to get it, however I know that they already have it. How do I fix this problem? The WhatsApp version I have is for iPhone.
  • What happens when you block someone on an iPhone 6, and they text you or call you? Specifically, does the phone keep ringing or does it say the call can't be made? Does the text deliver and just never show up on the receiving phone, or does the sender get a message saying the text can't be sent? (The other phone is not an iPhone.)
