Hi, I noticed something strange with the way how memory management is done on my Samsung A55 that has 8GB of RAM. So I have the Device Care widget and I can see that the amount of used RAM is always between 3.4GB and 5.3GB. Even if I open 70 apps (including big ones like Facebook, Instagram, Samsung Internet, TikTokel etc.) the RAM usage didn't go above 5.3GB. I installed Good Guardians and in Memory Guardian I choose Quick Switching Mode which supposedly keeps apps in memory for longer. It had minimal effect, the maximum RAM usage went up to 5.4GB. So my question: what is the reason for this? If my phone has 8GB RAM, why the system only ever uses 5.4GB of it? (I noticed something similar with my old OP 8T, that had 12GB RAM but the usage never ever went above 7.8GB) Is this some kind of Android behaviour/principle? Why "wasting" RAM? I'm curious about the technical reasons for this. Thank you.
