Help oNE PLUS ONE PHONE

[Geoff Blyth]

Just upgraded to a One Plus One phone, on old phone deleting gmails on computer deleted them from phone as well, they were synced.
I receive messages OK, deleting from Gmail on comp doesnt delete off phone anymore
Anyone have ant ideas to fix this problem

Do you have Google contact syncing turned off on the phone? Are the contacts stored as Google contacts (they will be if they were originally synced, but may not be if you transferred them some other way)?
