Got my phone and startet it without simcard and WLAN. After the initial settings, i connected it with my wlan and installed everything I need from fdroid. Then I rootet it with: download bootimage, flash bootimage, reboot, install superuser. Now I installed AFWall+ and gave Wlan-permission to those first installed apps (Firefox, DAV-droid and so on). Then activated protocoll. The app which insists the most to connect to internet is: contact: It wants to sync with Gmail. Now I need a replacement for contacts, Is there any easy app that does not need any network-connection?
Same goes for “Photo”, I replaced it with Quickpic, but Quickpic is second on the list “which app wants the most network connection”.
By the way: my FP2 works as expected, the hardware is fine, the software is partially ugly.
