nandohyphen1 That error occurs because the version (in the 'other' profile) is higher than the lower one u try to attempt installing (in private space), because of downgrade protection.
That why this is a weird case when u said earlier in the conversation, the app was updated
in private space, while thinking u have an older, working installation in the 'other profile'. As observed by inspecting the version code, this wasn't the case. U then were able to downgrade, meaning u had to delete all instances of the app, before being able to 'downgrade' (meaning installing 10411 from scratch). Attempting to install an older version of an app (with the same package id), isn't possible when there is an instance of that app with a higher versionnr available anywhere on your phone.
andrej567 No, not directly i assume, but an app could retrieve the number of (not from) the active sim, given the 'phone' permission is allowed ofcourse, even in private space. However this isn't really meaning 'apps can acces the sim directly', i'm unaware of the inner mechanics tbh, but wanted to clarify.
