Android is the result of the consortium, that includes heavyweights like google, motorola, samsung to name few, in their endeavour to create unrestricted standards of mobile phone OS
It is a linux based OS that powers 80% of the mobiles used today . Its popularity is primarily due to the revolutionary open source development kit that enables volumes of applications to become available to run on it.
However, android manufacturers don’t have the best track record when it comes to upgrading Android phones and tablets, especially when those devices are not popular flagships, or lower end models that have sold very well. At most, the devices get one official upgrade, and that’s it. So if your device is fairly recent, then chances are you will be getting an official update from the manufacturer. If the device is a very popular one, then your chances of having official updates increase.

- Press the Menu Button
- Go to Settings
- Go to About Phone

This is recommended especially if you have an older devices that has no chance of getting upgraded again, but you want to squeeze more life out of it before you buy a new one.
