Phone: Cubot X15 running stock Android 5.1. NOT rooted.
I have a few free and paid apps that need to run all the time. They are:
Rotate (paid), Should I Answer?, Prof Reminder, Micro CPU Monitor (paid), Network Monitor Pro (paid).
A few weeks ago, all these apps would start shortly after boot, as they need to, and remain in memory, doing their stuff with scarcely any negative effect on battery consumption.
However, since about 10 days ago, NONE of them will start on boot, and if I start them from the appropriate app icon, they run immediately, but a few minutes later they have all been killed by some unknown agency. I have never installed any so-called Task Killers, or so-called System Cleaners, although from time to time I use the very modest Cleaner tool from ES File Explorer (which has severed me very well for the last 6 years or so). With a cheap (but GREAT!) Chinese phone like this, one doesn't have the luxury of OTA upgrades, so nothing like that can be responsible. Battery drain remains about the same as before.
I had previously tried rooting the phone, but the only thing that worked was KingRoot, which I didn't trust, as it uses its own secretive Chinese SuperUser, and won't allow any respectable Super User alternative to run. So about 3 months ago I cleared it out and flashed the latest factory ROM I could find, re-installing my modest list of fave apps from the Play Store, rather than any backup. And all the apps ran as desired since then, until the killing problem suddenly asserted itsself. I can't think of any app I installed around then that might account for it.
I'm totally puzzled, and have been unable to get any help from googling my problem, because all I get from such searches is stuff about how to STOP apps auto-loading -- I can find nothing about how to make sure certain apps DO load....
Are there any system logs I can access to to looke for clues to my problem?
