You may need to transfer all the photos from your Android phone to your new iPhone if you want to swap your current Android Phone to iPhone. You can simply do this through a computer with iTunes installed. You need only to find the photos and videos on your Android phone, move them to your computer, sync them to iTunes, and then sync your new iPhone with iTunes. A similar process works for music, as we will outline below.
To transfer your photos from Android to iPhone, simply connect your Android phone to your PC or Mac. Choose the photos and videos you want to move, and drag them to a folder on your computer. For simplicity I would create a new folder on the Desktop.
Now plug in your iPhone to your PC or Mac, open iTunes, and click your iPhone. Click Photos, select the 'Sync Photos from' checkbox, and choose the folder into which you saved your photos. Click Apply and the photos will sync to your iPhone.
