at the moment wie do not have WLAN – and suddendly the Fairphone (1.8) tries to load a Fairphone Update (showing this in the “first line” of the screen). But I cannot see any further informations about this process, e.g. by clicking on the update notice.
The FP Updater app sometimes behaves a bit oddly… clear cache and data from the app and see if that helps. There are (as far as I know) no new updates available.
