Honestly it's extremely annoying my device locks me out from my data - that would be third entry to my list:

* Nextcloud cannot access all files, despite many other file managers can - at least Fdroid version works.

* File manager cannot access /sdcard/android/data - inconvenient workaround via adb

* App is allowed to decide if I can (manually) take screenshot/ocr the screen - usually it's banking app, that wants me to remember some long number - then I write it on closest piece of paper - awesome security. No workaround as far as I know.

If I wanted such treatment I would buy ios :-|
