Since the system update to Marshmallow, my Droid Maxx 2 has been giving me trouble: the Home and Recent Apps buttons no longer function and the easy-access settings panel that used to slide down from the top no longer appears when I drag my finger down from the top of the screen. In order to check a new text message without the other buttons working, I have to use the back button to get out of whatever I'm doing and then open Messaging. It has made navigating my phone ludicrously tedious. I used to swap between apps like tabs in a browser, but I can no longer do that.
Also, Marshmallow doesn't show me what permissions a new app wants to use: it waits until the app tries to use those permissions before asking for them. I always check what permissions an app will ask for before I bother to download it; now I have to download the app and wait for all the permissions to come up, one by one.
Lastly, I stopped getting all notifications. I checked each app and their permissions are still there. I'm clueless.
In researching these problems I discovered that most of them are touted as "features" (like "What's on tap," etc) so I assume there's no way to fix them -- unless I can remove the system update completely.
Is there a way to remove the system update from my Droid Maxx 2? If I do a factory reset, is there a way to prevent the system update from installing again? There was no warning or "opt out" option last time.
