Android 1.6 Donut

Android 1.6 Donut

Android V1.6, codename Donut, was released in September 2009. It fixed reboot errors in the OS as well as revamped photo and video features (i.e. camera interface) and better search integration. It also added support for larger screen size, and is the first version to offer Google turn-by-turn navigation feature.

Donut is usually defined as a small ring-shaped friedcake, is actually spelled doughnut, made out of rich, light dough and deep fried, then various sweet coating can be added. Please don't mistake this with bagel, which is baked, much denser, and usually salty.

Technically Android 1.5 wasn't the first version, but versions before that doesn't seem to have received any codenames. Stories were told that it was supposed to be version 1.2, but Google decided to make it a major revision and made it 1.5 instead, and gave it the dessert name "cupcake" as a codename, and that's when the "dessert series" got started.

A cupcake is a small cake, the size of an individual portion, baked in a cup-shaped mold, usually served with frosting on top.

What Is Android

                                        

What is Android?

Android is the name of the mobile operating system made by American company; Google. It most commonly comes installed on a variety of smartphones and tablets from a host of manufacturers offering users access to Google’s own services like Search, YouTube, Maps, Gmail and more.

This means you can easily look for information on the web, watch videos, search for directions and write emails on your phone, just as you would on your computer, but there’s more to Android than these simple examples.

What can an Android phone do?

Android phones are highly customisable and as such can be altered to suit your tastes and needs with wallpapers, themes and launchers which completely change the look of your device's interface. You can download applications to do all sorts of things like check your Facebook and Twitter feeds, manage your bank account, order pizza and play games. You can plan events on from your phone's calendar and see them on your computer or browse websites on your desktop and pick them up on your phone.

Another neat feature of Android is that it automatically backs up your contacts for you. When you set up an Android phone you’ll need to create a Google Account or sign in with an existing one. Every time you save a number to the address book of your Android phone it will be synced to your Google Account.

The benefit of this is that if you lose your phone all of your numbers will be saved. The next time you get an Android phone (or and iPhone or Windows Phone if you prefer) and sign in with your Google Account, all of your contacts and friend's numbers will be displayed in your new phone’s address book immediately, no need to transfer or back them up anywhere else.

Syncing is a way for your phone to keep all your information; websites, contacts, calendar entries and apps up-to-date. This can happen over your phone's mobile data or WiFi connection, seamlessly, in the background.
