When I get a device (computer or phone), I like to have a theme for the device. That could mean that the computer is named something specific, or the wallpaper is a certain style. The theme then lives with the device as if it’s a part of its identity.
When I bought my Nexus S, I decided that I would use a specific wallpaper that I had downloaded awhile before – it was a space theme to reflect the advanced nature of the phone (although the phone I had before was also an Android so…). I used that same wallpaper from the beginning and still have it on the phone name, so for me the image of the wallpaper is as much a part of the device as the hardware design. Here’s what it looks like (my home screen and just the wallpaper itself)
For my Nexus 4, I’m following a similar philosophy – here’s my new wallpaper and design:
One thing I decided to do was to make better use of folders to group functionality, which gives me more room so that I can make my layout more flexible.
