What operating system does your mobile phone run on?
I currently have a Samsung Galaxy Nexus (Android) and it's great, but there's a few features I'd change.
Obviously, like everyone else, am unhappy with the battery life. Still don't understand why I can get a smart phone that will last a FULL day (24+hours) with lots of use. But that's just me
Also, dislike the loudspeaker as it's on the back, and listening to youtube videos in an area with a few people talking is just ridiculous.
Camera is really awesome though! As is its ease of use and very quick operating system.
I love the microphone function, where I can talk and whatever I say, for example "pizza shop" will immediately bring up google maps with the names and list of all the pizza shops nearby.
