I’ve have been using an Android-powered HTC Wildfire from few weeks, and it’s been quite interesting experience.Now i became lover of Andriod OS.I have noticed several things that why Android completely dominates Symbian and wanted to share with you all.

1. Integration.
This is the first thing that Symbian really needs to address , specifically for Nokia handsets. As a part of procedue,whike setting up your Andriod phones for the first time,the strat up process will ask the user if he has google account,if the user selects yes,all the information such as,contacts,calender etc.. associated with your account is synchronized with the Android device.
But, On a Symbian powered device, the user will have to individually need to download,and set up the mail,contacts and other stuffs.and the user need to repeatedly need to login.
2. Applications.
This is the major advantage for the Andriod users.  At last count, the number of Apps on the Android Market exceeds the 100,000 mark.And still increasing,but Symbian Applications are less compare to Andriod.Its API is based on Java rather than C++ in conventional symbian OS.
3.Platform Updates
Any Patform updates can be done throught the-air, no need to connect to PC then update ur mobile as found on Symbian mobiles.As soon as the Platform updates come, we can update our mobile version from using GPRS/WiFi connection only, no need of PC.Still most of the Symbian featured mobile dont have this option.
The one big thing for me is that the Android browser is much, much better than the Symbian browser. I find I had difficulty opening some web sites on the Symbian browser. The Android browser seems to be able to open almost any web site I would visit on my PC. You can get around the Symbian browser problems by installing a different browser. However, Symbian does not seem to let you change default browsers for all applications. I can change the default browser in Symbian for email links, but I cannot do the same for Gravity (my Twitter app) or Facebook.
Android has surged past Symbian to become the world’s best-selling smartphone operating system, according to Canalys. Now Nokia is also not interested in Symbian ,so they joined with Microsoft to give competition to Android.
