What about the microusb connector, does it seem to hold for the stress when jacking the charger in and out?
I don't want that story again that was on the n900. Two of my n900 broke down on their usb connector. And after checking some of the threads here on TMO, it was not a simple thing to repair at all, so finally I gave that up.
It was the absolutely worst thing about the N900 I think, next to that stupid magnet on the backside that when it fell off caused the microsd card to fail detection. Also happened on both my N900.

I hope nothing of that kind is the story with the Jolla.
