I dont know if this is linked.<p>My friend askes me to install Tutamail on her phone recently.<p>She has been getting loads of spam and unsolicited mail on Gmail.<p>Initially downloaded it from the play store.<p>During installation a pop up appeared and asked me to upload the email address and the password of the new account.<p>So I installed F-droid to see if it was a glitch with the play store.<p>No! the phone again asked for the email address and password to be uploaded.<p>On both occassions if I clicked no to the pop up the install failed.<p>So there I was installing an encrypted email app on her phone and googly wanted to know the email address and the password and would not let me install it unless I shared the new encrypted email address and password with them.<p>I'm a custom rom man myself so have never come accross this before.
