That new default Android icon in 5.1 we pointed out earlier appears to be showing up in more places than expected. It's the basis for an updated Android Beam icon, which you can see below.

Left: Old, Right: New

Nice, right? The 5.0 icon was very retro, just like the old default icon that was replaced. Google only just gave Android Beam a spot in the share menu as of Android 5.0, so maybe that icon was a little rushed.

The only share icon left standing out is Bluetooth, which is still rounded and 3D-ish. The system component icon is still old and busted too, but that only appears in the app settings.
