Help Google Calendar not syncing (well) across devices

[WimYogya]

Hi,
I use 3 Google Calendars that should be stay synced, but whatever I try: they refuse to do it:
1. GoogleCalendar on PC - is always OK, its syncing with Outlook on PC is also always correct.
2. GoogleCalendar on Samsung Galaxy Tab 10 Tablet - often misses events from 1. Sometimes complete months or years are damaged. Only birthdays and other all day events are displayed. Same happens on tablet apps Samsung Calendar, DigiCal, aCalendar.
3. GoogleCalendar on Samsung Galaxy Core Duos smartphone - also misses events from 1 - but the missing ones are often different from the missing ones on the tablet! For the rest: same problem as device 2.

Observations:
a. New events added via device 2 or 3 are copied to 1 and to each other without problems.
b. New events added via device 1 are copied to 2 or 3 without problems, even on 'damaged dates'
c. Existing events on device 2 but missing on 3 will be added to 3 after I edit them on 2. And vice versa.
d. I have tried every available online advice to uninstall the GoogleCal on smartphone and tablet, cleaned the data, cleaned the local storage, reinstalled my whole phone etc. Same problems.

Any new insight?
Thanks!

I was hoping there would be a solution to WimYogya's issue. I have 2 clients that have the same or very similar issue, WimYogya has tested and documented this well. These clients have 2 PC’s and 2 Galaxy 5 phones and they just aren’t syncing across the board. Some items appear to be up to date but others are not.

Please post your ideas for a resolution to this. I know it is difficult to resolve something when the problem isn’t in your hands to test.
