In some Android apps there is a "Login with GMail" option. I often login with that.
Some apps are sending emails on my behalf to my GMail contacts, as I saw them in my "Sent items". I want to know how can I stop those apps spamming my friends? This is very irritating.
To stop the spamming I logged out from my device but still there are sent mails. If I uninstall the app there is no more sent mails, but I don't think this is the best solution available. Are there any better solutions?
