Log out Gmail - please urgent

My girlfriend has logged me in to Gmail with her acc so you can download an app for me

But we did not consider how I get out of there. That's almost a week ago and I came out and

Until now there was no problem but suddenly I have her contact and if I delete the on my phone then I do that on her

I've read in Google but that does not work for me

Please I NEED Help

Just log out? Uwu

Yes, that's not working! Otherwise I would not ask the question

I'm so desperate

Wat does not work? MORE INFORMATION… Just in the settings of the mobile phone under accounts unsubscribe…

Hej,

the problem is this: your apps, contacts, and settings on your phone are linked to the Google Account, and theirs, too, if you're exchanging your Google accounts with each other, which can cause problems or inconvenience. It's best to use only yours on your phone and only your Google Account on your phone.

Naturally.

All right then…

1.Go to the Gmail app.

2.Press on the profile picture

Manage 3 accounts on this device

4. Remove any email address
