By default android apps are installed directly to phone memory. Its fine if you have a phone with internal memory only or you have enough phone memory in your phone which you can access, its okay. But the problem occurs when you install so many apps, games in your phone. The phone performance gets poorer after the memory decreases. It is good to have enough free memory in your phone.Now you can’t install apps directly to your phone but one thing you can do. You can transfer the apps to memory card.To do this go to Settings > Applications > Storage useYou will see installed apps and their memory usage. You will also see the amount of used and free space on your phone memory.
