I had to factory reset… so delete all apps… right now… my aps are working well. On this day 26.10.2017 Facebook and messenger looks good. I dont use instagram or nova…
Only app that dont work is YR (for weather).
Sometimes i have the same issue. I install a new app, and Trebuchet Stops Working.
Last time it happened, i installed FaceApp, but usually every time i try to install a launcher (Nova or Google Now) i get the error, and every thing stops, Trebuchet, Settings, can’t install or uninstall any app, and my K910 keeps reseting.
