How to turn Galaxy Nexus auto-sync on, a non WordPress related TIPIf you own a Galaxy Nexus, one day you may be very surprised to find out that your device has stopped syncing. You check your accounts, and no surprise, sync is off for all your accounts. There seems not to be an easy way to turn auto-sync on manually.

Don’t know when Google will fix it. This has happened to me twice.

First time, I found the fix right way through Google, first page and top 5 results. Now thanks to Google ever-evolving algorithm to present you the best information, that little fix is nowhere to be found in Google search this time. Relevance or irrelevance?

Here is the quick fix, from my memory and for my own reference as well (the sync problem may occur again).

Settings -> Data usage
click on setting/menu -> re-select Auto-sync data

You are done!
