What does it mean “rooting” an android device ?

In the default configuration of an android device (smartphone or tablet), some elements are protected. Accessing or editing them requires granting special permissions. In systems of the unix family (android being one of them), these permissions are known as superuser or root permissions.

  1. hello there, how do you copy the to the sd card? ive downloaded it to my computer, but cant work out how to get it from my computer to the sd card?

    • Hi Jay,

      There several options to copy files to the sdcard:

      – If your computer is provided with a sd card reader, just extract the sd card from the phone and insert it in the computer
      – Or connect the phone to the computer, and in the phone select “Connect storage to PC”. The sdcard will be accesible as a removable drive
      – Or use the browser in the phone to download the file directly to the sdcard, instead of downloading it to the computer.
