Can I change my PS4 background from my phone?
On your PS4, go to your messages, click that image, and screenshot it. Then go to your screenshots and click the Options button on it, and make it your background image. You can Google wallpapers on your phone and easily set them as your background via this method.
How do I upload pictures to my PS4?
Can you transfer files from phone to PS4?
Android devices cannot transfer files directly to the PS4 through the USB port. The PS4 only accepts exFat or Fat32 files. Format your storage device (External hard drive, etc.) to either exFat or Fat32 to work with the PS4. You can then transfer your “Android” files to your PS4 indirectly.
