I have a galaxy z fold 3. It worked great for the first couple years, then problems started cropping up. Right around when the warranty ended, the inner screen became nonfunctional and the screen on the front started fracturing. The outer screen is too narrow for a lot of apps, and the inner one is too large for most apps to adapt. I highly recommend staying away from these types of devices. Also, Samsung is proving to be an incredibly frustrating company. For my next phone Ill be getting one of those repairable open source phones and putting Gnome on it.
Lol, i can’t think of PoE as anything but Power over Ethernet.
