I recently purchased my first Android phone (Qmobile Noir A10) with Ice Cream Sandwich installed on it. It has 512MB of RAM and 1GHz Dual-Core processor This is my first experience with Android. I checked all the apps pre-installed on it the first day, including Facebook twitter, Skype maps, yahoo messenger, geo news etc and installed few new ones like IMDb, whatsapp and viber.
Now whenever I click on the menu button and go to ‘manage apps’ section and then go to the ‘running’ apps tab, I see many of the apps running in the background and using around 270-280 MB out of total 512MB RAM.
I do not want all the apps to be running and using RAM and wi-fi at all the times. I just want to launch these whenever I want and then close down completely when I close them without their automatic relaunching with phone restart. Please guide me.
