I cant see the secure folder in my menu.. it just disappeared..anyone knows how to fix this? as you can see, according to googleplay store, i have it installed, but i cant open it nor i can find it in the menu.. I have Android 7

I have broken my phone's screen today, does anyone know if the warranty covers the replacement? if not, how much would it cost?

since the last android nougat 7.0 update, whenever I try to access the wifi settings, the settings crashes, is there any fix for it? or i am ought to wait for the next update?
