Thank you Jolla for the Update!
Installed it right now and updated from 4.2.0.19 to 4.2.0.21 .
Download size was 40 MB.
Have to report that after the complete download, update and restart, I came to enter the encryption code, then it tried to boot, but doesn’t work but rebooted after a short time.
But after the second reboot, it runs fine, without visible problems. Storeman asked again for access to something, but only one time.
Phone seems ot work fine, including browser, LLs player, AllRadio, File manager, Books, Quanto Fa, Wunderfitz, Unplayer, Camera, Pure Maps. (tested)
Phone works fine!
edit: saw right now that browser is on (felt) double or triple speed! Thanks again Jolla!
