Google just launched its first Android P Developer Preview, meaning the next update to your smartphone is here – if you're willing to download very unfinished software.

New Android P features include turning your phone into a wireless keyboard or mouse, support for new photos and video compression codecs and Wi-Fi Round-Trip-Time. That last one will enable support for indoor position tracking, so your smartphone can guide you through even more mapped-out adventures.
