How do I free up RAM for my Samsung Note II LTE GT-N7105 on stock Android 4.3, rooted?
I am an Android retarded user looking for a patient teacher who will walk me through the Android RAM mysteries and answer a few question and, in exchnage, I can teach about the secret world of Traditional Neapolitan coffee infusion: home roasting, grinding, preparation and... savouring or, alternatively, Home Theatre! Your pick!
On average, at startup,
- Clean Master shows:
> 50% RAM
> 70% Device Storage
> 20% SDcard External Storage.
- Titanium Back shows:
> 500MB free RAM (of 2.11GB)
> 4GB free Internal+Media (of 10.9GB)
> 50GB free ExtSDcard (of 63.8GB)
Starting with these numbers, the device freezes after a bit of usage of the Swipe (Nuance) App. But I recently played with a 78 year old banker's GT-N7105, which was 20 times faster than mine, while running the same Swipe keyboard App: "My nephew geeks around a forum called xda-developers!"
1. In general, what's the relationship between installed Apps and RAM usage? Sometimes when I kill an app it frees up a bit of RAM, sometimes a lot and sometimes nothing at all.
2. Do installed (but not opened) Apps take up RAM space just by sitting in my Apps drawer? Should I uninstall all the Apps which I downloaded because "one day I might need it" and never used them or are they harmless (RAM wise) if I don't open them?
3. Do Apps which have been launched and now sit in the background take up RAM (as in Windows)?
4. Is there any difference between "fereezing" and "un-installing" an app as far as device operation speed is concerned?
5. Do I need to make sure that Apps don't start up if I don't need them (Google Play Services, Google Play Store, Goggle Translation, YouTube, Video Player, S Voice, Picasa Uploader, Nearby Service, Nearby Devices, SNS)?
6. If they eat up RAM, how do I make sure that they don't self start? Android Assistant App?
7. If background open Apps eat up RAM, is there a way to kill them automatically once I open a new one without loosing the cahced data which i might be using?
Thanks in advance for your time and expertise.
