As per title, SO I finally bite the bullet and bought my first REdmi Note 4x ( my first ever expensive phone). I'd search and follow advises that are in a handful of articles. However, no luck so far, due to the 'move to SD card' is not there. Im using Nougat btw, also what is/are advantage of LineageOS over Nougat ( if there is any ). Thanks.
This is what MovetoSDCard app shows https://imgur.com/a/ooe67. When I choose the "Move to sdcard" option that is in the apps
TLDR; All I want to do is move my camera apps to SD card so that I can record more video.
You'd need to mount the SD card as Extensible storage.
You should have been prompted with that option on inserting the card.
You still wont get a choice of where apps will install, the card will just appear to be an extension of the inbuilt storage and be used as required.
