I want to ask, what is the point of having head unit with 8 or 12Gb RAM when every time device goes to sleep every app is killed. I have set the nokill function for apps which should not be killed I have also disabled all battery optimizations in app properties but it does not work properly. My previous HU with uis7862 and 6Gb RAM had never this issue and i have never tweaked anything. As example i have TIDAL playing, when i leave the car for an hour and then I turn on the Head unit tidal is killed. I have already set routine for opening the app, wait 5sec. and then play but i am using more media players randomly and this realy is not the way it should be working. As i said with my previous Head unit it was everything fully automatic as soon as i pressed play after head unit wake up the last used media player was playing, no tweaking no app opening first pressing play and then pressing home.
