Why does android aggressively unload apps when there is enough memory?

Question

Android

Question for Android experts. Why does Android aggressively unload applications when the free memory limit is 400-500 MB? That is, when the available RAM becomes less than 400 MB, the android kills the active application. This is especially true on smart phones with 2 gigs - the memory fills up and the system kills the browser with the text typed in it, instead of unloading unnecessary applications from the cache. There is a version that free 500 MB are needed to quickly launch capacious applications, but when a smart has only 500 MB of space for user applications and the system reserves 500 MB, this does not look justified. Why is this reserve needed at all and is it possible to somehow solve this problem?

Answer 1

There should be a corresponding option in the android settings - an application unloading strategy (how much free memory to keep, how many applications to keep running, as well as advanced energy saving settings, you can specify your profiles for certain applications), also some vendors shove their Trojans under the guise of antivirus programs and memory cleaners , to simulate activities, they clean the memory on a whim - turn it off by all means.
