There you can find phone backgrounds for your iphone and android. Unfortunately, since each phone has a different resolution, I cannot quarantee
it fits your phone perfectly. Instead you can follow these steps to make sure it fits:
1. Go to Whatismyscreenresolution.com and find out your resolution size.
2. Crop it using a online croppping tool like Picresize or Cut My Pic. (You can also use a program like Photoshop).
3. Save the altered image as your phone background! ^_^
