Hi Tarhestan! Thanks for your entry. I'm new to Android design so I'm not sure what to suggest to improve. From what I've seen of android design the buttons seem to be at the top more frequently. Do you have any other ideas? Also, I think the buttons tend to be either square or round but not rounded like iPhone buttons. I think maybe a more square version of #7 with the buttons placed at the top might be a good start. Any other changes you can think of would be great.
