I need program to backup and restore my contacts on Android phone. It must:
backup and restore contacts
backup and restore as is:
a. phone contacts to phone contacts
b. first SIM contacts to first SIM contacts
c. second SIM contacts to second SIM contacts
d. Google contacts to Google contacts (this is good but not strongly required)
I need ability to view (and maybe to edit) backuped contacts on a desktop computer (maybe from simple text editor) with Ubuntu Linux.
I need ability to change type of contact (phone, SIM, Google, ...) one by one on my mobile phone and/or in backuped contacts on desktop computer.
P.S.: I have Android 4.4.
