Unformatted text preview: Android iPhone OS Comparison David Thomas April 12, 2010 1 History 1.1 Android Android OS started as a project from Android Inc., based out of California. Their ideas and work caught the attention of Google, who absorbed their company. The men behind Android, Andy Rubin, Nick Sears, Rich Miner, and Chris White headed up the team at Google to start an open source mobile phone operating system based on the Linux kernel.[8] In November of 2007, The Open Handset Alliance consist- ing of Google, Texas Instruments, Broadcom Corporation,HTC, Intel, LG, Marvell Technology Group, Motorola, Nvidia, Qualcomm, Samsung Electronics, Sprint Nex- tel and T-Mobile, released the first official public information regarding Android, including that it would use Linux kernel version 2.6.

For example, web browsing on the iPhone OS is done through Safari. Mail and Calendar events are handled through scaled down versions of Apple Mail and Apple iCal.[9] 2 Supported Devices 2.1 Android Android supports many innovative and industry standard features for mobile phones, as well as other platforms that Android could be adapted to in the future. For ex- ample, the graphics platform is expandable from traditional smart phone layouts to 2D and 3D graphics using OpenGL over VGA.[8] Android supports all of the major connectivity technologies from mobile phones using GSM/CDMA to more personal connections via Bluetooth and Wi-Fi. Android is equipped to use video and still camera modes, touch screens, GPS, accelerometers, accelerated 3D graph- ics, and digital compasses.
