Z8350 low performance, would single android boot improve?

Hi All, my Hi12 Z8350 is not a good performer. Apps like Facebook take ages to start, so I’m thinking its just too much sacrifice on memory to run as dual device.

My serial is Q64G45171000961

Can someone advise is my system out of date from the pic below?

If its possible to run as pure Android single boot, can someone give me the link to the correct files I need ( the forum page is very confusing regarding which files I need )
