Hmm… I would say… this is not a very good error message.

Anybody want to give me advice on how to back up everything important from an Android phone? Assume I have about… eight hours and somewhere in there I have to sleep.

I guess I'm using adb, but I barely know what I'm supposed to be grabbing, also neither adb pull nor the https://github.com/jb2170/better-adb-sync tool google says to use is like… y'know… doing anything…

What I really really REALLY need is an android file extraction tool that, when it hits a permission error on trying to download a file, will skip that file and download everything else instead of hard aborting
Failing that, what I'd really really REALLY like is a way to back up my Element/Signal keys/conversations without uploading them to the Element or Signal server. And also ideally without my phone having a screen
@mcc Not a general solution, but Signal Android has “export backup to file”, at least. (Only Android, for the time being, for historical reasons that are probably cold comfort to someone whose phone fell in a lake. :-/ )
@jrose That's great. Question: Does this feature require your phone to have a screen
@mcc @jrose depending on the phone, if you have a USBC to HDMI dongle around you might be able to give it a screen...

@megmac @mcc @jrose Here are some possibly interesting apps UXRs use in usability testing for Android, in case you’re able to install.

@skry @megmac @jrose Found something called "scrcpy". It's in Ubuntu's apt installer. Seems to work pretty well.
