1. Uninstall apps from your home screen or app drawer
In Android Marshmallow you can now uninstall an app on your home screen or in your app drawer simply by long-pressing it.
At the top of the screen you'll now see options for Remove or Uninstall on the home screen, or App Info and Uninstall in the app drawer. Simply drag the app icon to the one you want.
You can now instantly uninstall apps from the home screen or app drawer.
2. Activate Developer options
Developer options are nothing new, but there are a few new ones in Android Marshmallow. To access Developer options, go to Settings > About Phone and tap Build Number seven times until a toast pop-up notifies you that you are now a developer.
Back up a step and you'll see Developer options listed right above About Phone . This is where you can enable USB Debugging, OEM unlocking or Show touches, tweak animations or access some of the other tips below.
Enabling Developer Options is always one of the first things we do.
3. Grant app permissions individually
Granular app
permissions was the holy grail of the Android Marshmallow release. We
all hoped it would pan out but no one really believed it would. We had
always been told that denying specific app permissions within a
third-party app could break it.
Now, however, Android lets you
manage app permissions individually, without developers having had to do
anything, and everything seems to work swimmingly.
You can view and toggle permissions for an individual app. To access app permissions, go to Settings > Apps and tap
an individual app to see its permissions. Then simply flip the switch
for the permissions you do or don't want to grant it.
You can also view a list of permissions to see which have been granted to which apps. Just go to Settings > Apps , then tap the overflow menu in the top right corner and go to Advanced > App Permissions .
You can also view app permissions by permission type.
4. Customize Quick Settings using System UI Tuner
To enable the System UI Tuner , bring down your Quick Settings
menu (swipe down from the top of your phone with two fingers) and tap
and hold the settings button (cog wheel) for five seconds. When you let
go you will be asked if you would like to enable System UI Tuner . Select yes and you'll see System UI Tuner at the bottom of your Settings list.
In System UI Tuner , tap Quick Settings and you'll see a mockup of your Quick Settings shade.
You can add tiles (press the + at the bottom), move the toggles around
(tap and drag) or delete toggles (tap and drag to the bottom). Your
changes will be reflected in the Quick Settings menu.
The UI Tuner lets you rearrange your Quick Settings menu.
