The standard way of installing themes on 7.1.1 requires a theme engine such as Substratum (
https://play.google.com/store/apps/details?...jekt.substratum), but Substratum requires root.
Before I go away and root my Gemini (cue endless backup/restore hassle), are there any ways of installing a theme
without first obtaining root?
NB: I'm only after this because I want a universal dark theme; the screen glare in apps that don't individually provide a dark theme is ... annoying. If there's a way to enable a nighttime mode globally, I'd settle for that.
