The RAM of mobile devices has grown a lot during the last few years. While phones in 2012 (e.g. S3 LTE GT-i9305 and Note 2) just entered the 2 GB territory, we have phones with 12 GB RAM today. It would be good if users could specify some applications that are protected from being closed by the *OOM (out-of-memory)* killer the background. Maybe it is already possible with a solution that requires rooting, but mobile phone vendors and operating systems should introduce it as a native feature.
