a User-Phone would be a Samsung Galaxs S2 or S3. A phone which was changed be the manufacturer. It gives you a closer look to how you games would run on a phone a lot of people using.
A pure phone is afair the nexus. It has the ra Android. Nothing changed, just Android.

Oh well… That is based on what you target. There are a lot of cheap tablets, but performance is bad. Then there are pads like the Galaxy Tab (Damn that sounds like I’m a Samsung Fan xD). Again I would look after a device which a lot of people have. That gives you a good view on problems you need to solve (Well until today my only convern is memory but if you not creating instances all the time, without pooling you should be fine).
