I have a problem with my device. It constantly closes apps to free up memory. For example, if I am using a running tracker and decide to take a picture, the running app stops and I find out when I return home, so frustrating. I think 2 gb of ram should be capable of running more than one app + launcher and system/kernel stuff. I am using Nova instead of the default launcher, which should be lighter right? I know I can lock apps in the memory but this also means that I have those apps running when I do not need to anymore. Also, when clearing the last app page, battery trackers like Gsam often stop working. Why should this behavior be so different of other phones I have (1gb but keeps fitness and battery trackers running)?
