Tried.... I'm still logged in... if I type gmail in browser it pulls up my email.. I don't have to sign in....
I'm trying to make it so I can log in with Gmail account name and password ... don't want it to stay sighed in .
Not sure y it keeps me in....I even restarted my tablet too
While I never use the mobile version of Gmail on my Nexus 6, because I obviously have the Gmail app, I just ran a test to confirm a hunch...
My guess, and it seems to be correct, is that as long as you are using an Android device with Google Play Services, that requires you to be logged in to use, you will always still be automatically logged into Gmail, since your Google Account is basically your Gmail Account.
Basically, what I am trying to say is, if you want to be signed out of your Gmail Account, while using an Android phone, you would have to do so, without being signed in to Google Play Services, which doing so would render your Android phone practicality useless.
The only alternative, that I can possibly think of, would be to Root your phone, stop using Google Services and GApps all together, and install F-Droid, Amazon Underground App Store, Amazon Fire OS or some other Open Source Linux based OS.
Otherwise, you are stuck with being logged into Gmail on your Android phone, while using your Android phone.
