My PC always has 3 games installed, and depending on the distro I'm currently on they may have come directly from the default repos:

• Battle for Wesnoth
• Warzone 2100
• OpenRCT2

I have lost count of how hours I have in all 3.

Which errors are we talking about?

You have 1 notification concerning Nautilus, be it a file copy was completed or the like. If you click the notification center (the Date/Time on the top bar) and clear out your notifications there the 1 should go away.

Also keep in mind that Ubuntu Touch doesn't support VoLTE at this time which is a problem if you live in the US where it's required for basic voice support.

Last I saw they were hoping to have it fixed by the end of the year but am unsure of the current progress.
