How do you share photos with another Android user? By default you can share files with another Android phone over Bluetooth. Just tap the share icon and it’ll give you the option to send via Bluetooth together with other sharing methods you can use, including via email, onto Facebook, into third-party sharing tools like Dropbox and messaging tools like ChatON and WhatsApp.
Unfortunately, sharing files over Bluetooth doesn’t work when you want to send the file to an iOS device. In that case, just use an app called Bump. It works across platforms for some clean file-sharing fun.
