Complete noob to the Pinephone 64, cannot set time and date.

One thing I noticed: got an incoming call this afternoon while messing with some settings, and picked up, and heard nothing. Then I found I had to hit the "speaker" button on the dialer page to get sound. I hope I don't have to do this every time.

You should really not use the preinstalled OS (which should be Manjaro with the Plasma Mobile UI if you bought your phone recently), it is very buggy and probably also really outdated now. It would be an unnecessarily frustrating experience. Instead, flash a recent OS (see https://wiki.pine64.org/wiki/PinePhone_S...e_Releases for a list of available OS). I didn't try to use Plasma Mobile in the last few months, but each time I tried it was very unstable and crashed every now and then. I find Phosh to be much more reliable, probably still the most reliable UI as of now.
