The last champignon dish you’re going to prepare.

AfaIk, Shelter is using the built in work profile of Android, as not every UI/ vendor has made it available to the users. (There is no visible button or option in the settings menu.)
E.g. Samsung smartphones have a “work mode”, but the last time I’ve used it (It may be different in current models), it only allowed for second accounts of selected apps like WhatsApp and hence, was a crippled implentation of the Android feature. My Android 11 Samsung tablet has complete multi user support, not only “work mode”.

I just wanted to add the Wiki article. The spelling of Müller with ‘u’ instead of ‘ü’ Muller would indicate he’d be from France or US and would be pronounced very differently Müller vs. Muller.
Thanks for hint on my typo. I’ve corrected that.

As the article is denoted as a comment, it is not its aim to be unbiased journalism.

The query actually shows a lack of confidence. He should have googled “How to recover a file from /dev/null?” instead.
