Aaron2017 , Jan 16, 2022 : Yeah, with Nova you get the full customisation of the old OP launcher (and more even), like setting the grid size, changing icons etc. You could have it look exactly like it used to on OxygenOS 11 if you want. Not sure, but you would have to get the paid version i think, at least if you want all customization options
Aaron2017 , Jan 16, 2022 : If you mean the one from OxygenOS 11, as far as i know that's not possible.
Tobikage , Jan 16, 2022 : Find the apk and install it like every other app ? Why would it be any different ? If it works...it works. If it doesn't , then you have no option. Do keep in mind the latest Oxygen OS / OS12 is / will be based on ColourOS so there may be compatibility issues.
