My Galaxy S7 edge has been rebooted automatically. So I installed the last update suggested in my settings (that I was ignoring for almost 2 weeks). Now I'm not able to use many feathers, as the left touch button that shows opened apps, and I can't recieve notifications even if I hear the sound of it. Also, my personal settings has been reset.
Is there any way to fix that without flashing it or applying Factory Data Reset since I have plenty of apps and accounts that I want to keep.
