Google held an event to highlight some of the key software improvements for android. These will be present in the new Nexus 5, making this handset potentially super amazing. The improvements are as follows –

Hangouts
-Added Single tap location sharing
-Added the use of Animated GIFs
-SMS integration so all your messaging can be in one place. Finally an iMessage competitor.
-Auto Awesome features such as boosting the light of people that are in the Hangout.
-Hangouts On Air – Better planning including a dedicated event page plus special editing features

Photos
– Backup – Backing up photos on Google+ has always been full size by default, but iOS users will get auto backup as well with their next update.
– Highlight – Google+ has been picking out our best photos since Google I/O, but they have improved the algorithm.
– Search – We already could search our photos, but 1,000 additional words have been added so that you can search your images even if they aren’t tagged.
– Editing – Auto Enhance has been around since Google I/O for those that have no time, but Snapseed is also available for those that are more experienced and the Google Nik Collection for the seasoned pros.
– You can now adjust the Auto Enhance setting to Low or High and you can also control it by album. Snapseed adds HDR Scape, which takes any photo and converts them to HDR with one touch.
– Auto Awesome gets two new features – Auto Awesome Action and Auto Awesome Eraser

Auto Awesome Movies
– Google will take your photos and videos from an event and put them all together in one movie set to music. This can be done automatically or manually. It includes stabilization, music, automatic cuts, and effects. Users will have full control for further editing including trimming and how long the video is to be. As to music, you will be able to choose from a predefined set of licenced tunes. This seems like HTC Zoe’s.
