Hello, I just got my SGS2 recently ( international version). It is my first Android smartphone. I have some questions concerning the phone. 1- There are two types of running processes: RUNNING PROCESSES and CACHE RUNNING PROCESSES. What is the difference between these two and what are the running processes ? ( they are not the applications that i am using...) When i clear the RAM memory the processes comes back... and my ram ysage is always between 420 and 500 / 837 Mb. 2- I saw in an other post that the phone has around 13.5 Gb of interneal storage divided into 1.9 Gb for system storage and the remaining for the user. I didnt mount an external card yet. So the /sdcard is actually the internal memory and /sdcard/sdcard_external is empty. When i install an app where does this app goes ? in the 1.9 or the 11.5 ? When i go in the file manager i can see some folders created by the apps but its actually files for the app cache or something like that. So the question is where does the phone store the application "executables " ? 3- when i mount an sd card, some applications that i have downloaded can be transfered to the SD card ( but yet i cant see them in file manager) and some other applications cant be transfere. Why ? 4- The stock video player displays all the video files stored ont the phone...how can i display ONLY my series and movies ? 5- When i close the applications: messages, music, internet " with the back button they dont quit. I need to kill them in the task manager. Is it normal ? ( all the other applications quit by pushing the back button) Thank You in advance for your help and excuse my bad english.
