@formerFP.Com.Manager: When the Fairphone 3 came out with Android 9, the easy possibility to incorporate an SD card into Internal storage wasn’t there. It was only possible to get this functionality via more obscure ways.
Our understanding here was that Google had removed the easy GUI access to the feature in AOSP, and with reason, because using an SD card as Internal storage was never ever a good idea technically.
Now with Android 10 the easy access to the feature seems to be back, and it has caused some grief for several users already.
Could Fairphone please investigate whether the easy possibility to let an SD card be formatted as Internal storage could be removed from Fairphone OS again to avoid trouble?
