How secure is sending files over Bluetooth? (lemmy.ml)

If I pair my Android phone and my laptop, I can share files over Bluetooth from the phone to the laptop. I've started finding this a really convenient method for me to send files to a Linux laptop without needing to install a separate app on either the phone or my laptop. Especially when I'm away from my home network (I use SFTP at home).

How secure is this? Is there encryption by default and could someone else nearby with a receiver potentially decode the file you're sending?

Android will update and restart your shit without consent at night so your phone doesn't fully boot and your alarm doesn't go off. Ask how I know.

There's a way (at least on samsung) to disable auto updates.

Turn off "Auto update over wifi", then mark all wifi networks as "metered". Voila! The system will treat wifi as mobile data and not auto download the update.

Btw, in modern android versions, alarm will work in BFU (Before First Unlock) mode if you use the system clock app. (~~third-party alarm apps will not work in BFU mode~~ Actually, third-party alarm apps do work)

Then there's a nonzero chance I coincidentally slept through it or shut it off while sleeping.
