Hello, my new android 4 e-mail app has aproblem (I think), When I type new message, than I tick a contact button - I find my contacts twice duplicated 
I can't manage these contacts, why it collected three and four times?
This is usually caused by the address/contact being added to the phone from several sources (Gmail, Facebook, local contacts, company server etc.). Lets say you have a contact saved on your Gmail account and then you have this person as a friend on Facebook you will have this person in two contacts.
To see all contacts in your phone, open contacts, press menubutton, go to filter and enable all options under accounts.
Thanx, I did not sync all acconts and restart android 4, Now looks all things as ok
