How does Android Oreo work? Does it shut off apps which were opened, but then closed and screen was turned off? Because as far as I remember in older version of Androids like kitkat if u would open app, then close or minimize and even turn off screen, app was still running unless u would clear off cache by swiping off those apps with finger or just press "cleaner/booster".
For example if I will open Google News, then press Home button & turn off my screen and after few minutes open my phone screen again and press recent apps it will show me that it's still there opened, but will this also mean that it's running in background? Or Oreo will be smart and think that it's not necessary to leave app in background and will disable it itself?
My main goal for these questions is should I clear cache all the time before turning off my screen so apps aren't running which I don't want to run or Oreo will take care of them?
