Just drove ~600 km with Here maps on Jolla running SFOS 2.0 preview. Works ok , it seems response time of thi sprogram has slightly improved but voice through crappy Jolla speaker is too faint in comparison with almost all other mobile phone speakers. I am not sure if the Jolla speaker is to blame for this or the way they built it in the housing.

Problem:

2 times I got a strange error throwing me out of Here maps: display with "failed to update" screen with check mark, no options. Sorry I could not make screen shot while driving

After putting that away, Here maps stayed minimized with green shade app cover.

The Jolla touch screen would respond to nothing anymore, only showing app cover screen.

But the system was still alive (seeing the network strength indicators change)

Only reboot of system could restore normal functionality.
