Android is an intuitive operating system but having said that there are some things that you may wish to do but you are just not sure how; or you just wish to make sure you know exactly how to use Android to its full potential.
We have come across (sorry if you have seen them before) a set of user guides.
So thanks to Google, you can now find out he answers to your questions.
Click one of the images to be taken through to a PDF user guide for either Android 2.2.1 or 2.3.
There are large manuals, so may take some time to load! Do also bear in mind this these guides are for non customised versions of Android, so if you have a HTC, Samsung or Motorola, some processes and screens will vary due to manufacturer customisation.
