It has been many days since the Stem application for Android was in beta. Many people including me got the invite to join in and test it out, the application was quite stable though there were a few bugs while chatting and sometimes lagging on my Galaxy Nexus but now Valve has announced that Steam app for Android is available for everyone to use.
Currently you need to have a steam account to log in, if you have never used steam before on your desktop then you can sign up for it from the phone itself. This will be a great application for all the gamers and Valve fans. With this application you can chat with your steam friends, view the various communities and profiles, go through the gaming news, etc.
So if you are a gamer and willing to download Steam for Android then you can either download it from the Android market or click here
