My XA2+ was in 4.2 and I updated it first in 4.3 and then in 4.3.0.15. This time no troubles, everything works fine! Only one weird thing: when I go from the Sailfish Forum app to the browser, it shows two browser icons plus icons from Qwant and Magic Earth, two Android apps that I have. Also Webcat is mentioned, without an icon, while I skipped Webcat some time ago.
