From time to time I get the "Android Is Starting Optimising App" message.
I understand that there might be an option to reset it
My phone is like the one in this video https://www.youtube.com/watch?v=skyjFQERMQM
I did get this menu up on my phone as shown in the pic from video at 2:48

That video shows a factory reset though(which you get choosing the eMMC option), but I don't want to do a factory reset, I don't want to wipe everything off my phone every time I get this message!
I heard there might be a cache of some kind that is safe to delete, that would remove that message, but I can't see the option to delete that.
If I go to settings..about, it says DOOGEE-Y6C-Android6.0-2017015
It started doing this after some kind of update that I think happened automatically.
It takes 20min sometimes and that's when it's only 1 app to 'optimise'.(which as been common recently) B) It can happen any time, like twice in one day, i'm worried about powering my phone off because if I get in my car to make a journey and power it on so as to use google maps, it may take my phone 20min at that screen. If i'm in a shop that is to close in 10min, and I power up my phone to check something, the shop will be closed by the time it is up. Often I need to use my phone within a minute or two of turning it on.
