Android is one of the best and most widely used mobile OSes on cell phones today. Founded by Andy Rubin, Rich Miner, Nick Sears and Chris White in Palo Alto, California; it has come a long way in development. They originally wanted to develop software for cameras, but after realizing that cameras do not have a very large market, they went on secretly developing “Android” – an OS that would rival Symbian and Windows Mobile. “We wanted smarter mobile devices that are more aware of its owner’s location and preferences,” Andy Rubin said, when he came up with the idea of Android.
On August 17th 2005, Google acquired Android Inc., and from then on it was all “uphill” for Rubin, Miner & White. Back then, no one knew whether or not Google was going to enter the mobile market with this move. Since 2008, Android has seen numerous updates (Alpha 1.0, Beta 1.1, Cupcake 1.5, Donut 1.6, Éclair 2.0 – 2.1, Froyo 2.2 – 2.2.3, Gingerbread 2.3 – 2.3.7, Honeycomb 3.0 – 3.2.6, Ice Cream Sandwich 4.0 – 4.3.1, Jelly Bean 4.1 – 4.3.1, Kitkat 4.4 – 4.4.4, Lollipop 5.0 – 5.0.2) and with these updates, they have embedded some commands that experienced Android users or people with basic technical Android knowledge can tweak and play around with. Below is the list of codes (NOTE: they are general codes and they should work with most Android phones, however, they may NOT work with Android’s latest update, Lollipop):
