    I have Samsung GS5. Downloaded Lollipop about 2 weeks ago, after 10 days Google Calendar app & aCalendar app can be opened but the content (events, birthdays, etc) doesn't appear - calendars are empty.

    Welcome to Android Central! Were the events you were entering associated with your Google account or the local Phone account (or Samsung account)? Go to your Google Calendar on the web--do you see all of the events there?

    thanks. the events are all associated with my Google account. on the web I do see all the events on my Google calendar. I think that the problem I encounter is because of the Lollipop. Any help would be much appreciated.

    Go to Settings>Accounts-Google>[your Google account]​, and make sure Calendar is checked on. If that doesn't work, try removing your Google account completely, then add it back again.

    thanks. Calendar is checked. I have 2 Google accounts and removed them as per your suggestion, then added them back. So far nothing helped.

    This might be redundant, but go to the App Manager, select Calendar, and Clear Cache/Clear Data, then Force Stop. Now open it again and wait a few seconds for it to sync.

    In the Calendar app's settings, you have it set to display the preferred account, right? And you've already tried tapping the various calendars to make sure they haven't been toggled off?

    yes, I did all of that. The content comes and goes. Sometime when I tap the app, the content is there and sometime it's not. Your advice for the Clear Cache/Clear Data and then Force Stop works to have the content back but then later on, it may not show again.

    Scratching my head here. Try wiping the system cache partition, which won't erase any personal data: http://support.t-mobile.com/docs/DOC-10404

    I found out that the only thing that works is when I open the app manager app and press the boost button. Then, the Google Calendar app shows the full content.

    Is that a preinstalled app manager, or a 3rd party one?

    it's a preinstalled app. so far it works, though I don't understand why and what the boost is for.

    "Boosting" usually means closing a bunch of apps from RAM. This can be useful if an app is malfunctioning and hogging too much RAM, bogging down the system. But it's not a great habit to get into, because the way Android works, the system will just open the same or some other apps to keep RAM relatively full.
