Well, this one helped me a lot, in case of oom. Also I edited a couple of files, to make these values last after reboot. I think its worth at least trying.

example:

Here maps, Pou ( ), Opera mobile, Aptoide store, Shazam, WPS office, Firefox, Angry birds Rio and video still playing in background from LLS player (paused because of screenshot app) Of course, there is a slowdown, but no crashes.
