Hi. I have a BV7000 Pro since April and I am surprised to see how aggressive the memory management is :
The phone keeps closing apps in the background (I'm not talking about media app but all apps that aren't active anymore) after a few minutes and keeps only 3 or so apps in memory if you start switching.
This phone has 4 GB Ram and should be able to not clean so frequently the last used apps list. As you know opening an app is not only annoying but can actually consume much more battery (using cpu) and data.
Could your software engineer take a look at the settings concerning this?
