How can I save all contacts into google account? I did it using Gingerbread (Samsung Galaxy Ace 2), but with Ice Cream Sandwich (LG L5) I don't see appropriate action for that.
Previously I entered Contacts (ok), then selected Settings (ok), executed Google Merge (no such option), and Sync Data (disabled all the time).
I see only one available (not disabled) item that is relevant -- configuring sync option for my account, but I understand it will work non-stop, and I want action on demand, just from time to time, when I explicitly select it, not enabling a background sync process.
What also worries me, that in GB I could choose where to store contacts (phone, SIM, google), in ICS after initial import from SIM card to phone, I cannot choose anything.
UPDATE -- (hardcore) WORKAROUND
I found that for given single contact I can switch its type from phone to google, nice, but it does not solve the problem due to the amount of contacts.
UPDATE -- DON'T DO THIS
I tried to somehow do it automatically, so I did (but you don't):

change the mode of sending vcard to single file
share contacts
select all
type: gmail
recipient -- yourself
send
OK, switch to gmail app
open the attachment with contacts
choose target as google account
all contacts will be merged with existing ones, but now as google ones

And the last step is killing this workaround. Why? Because some contacts will be added (so when you had &quot;A&quot; you will have &quot;A&quot; for phone and &quot;A&quot; for google), the others will be joined (so when you had &quot;A&quot; you will have &quot;A&quot; as before, but now with double type -- phone and google). In short -- the result is mess. Now I have more work to do than manually switching one by one type of the contacts. Geee, progress, right? ;-/
If you want to "sync on demand only": Just enable sync at the time of demand for, say, 10 minutes while connected to your local Wifi -- and then disable it again. Enough time for the service to get its job done. You can do so in "Accounts &amp; Sync"1, after chosing your Google account:

 

If next to "Sync contacts" you see the same circular symbol as the screenshot2 shows next to Sync Google Reader, you probably do not even need to activate the permanent sync, but simply hit it for a one-time "sync on demand".
