I did not pose the right question. When I switch on I am told that 27 apps are running in the background, running my battery down and using the processing power. I am briefly offered an app which claims it will deal with the problem .The screen disappears before I manage to make a note of the app name, and anyway I hesitate to instal an app about which I know nothing. I am increasingly frustrated and seek help. I am not technically fluent.
My 5 questions therefore are
1. How do I find which apps are running (in the background or foreground) and which of them were autostarted ?
2 which apps is it safe to delete, or which to kill, (or which would it be unsafe to remove if that is the shorter list!).?
3. How do I control which apps autostart?
4 I seem to have a long list of installed apps, most of which I do not recognise. Searching with google to find what the apps are for is not usually fruitful. Any suggestions of how else to identify the purpose of an app?
5 Using 'settings' I am offered the option to uninstall updates but not to uninstall the app. Is there another way? (Unknown apps include (among many others) Automation test; badge provider; Blue Sea; certificate installer; context provider; CoolEUKor; CSC; DSM forwarding; DSNLawnmo; enterpriseSysScopeSerevice; flashannotateSc vc
; fiipboard; many google apps such as google play moves &TV(which I certainly would not use); Helv Neue S; INDIService manager; kobo; (the list seems almost endless)
So many questions.
Let me try to answer the 1st one. As for my phone, in Settings - Developer options - Running services, I can view and control all currently running services.
