I recently switched from a Wiko LENNY (don't laugh, it was my first phone) to a Samsung Galaxy S7. When I tested notifications at first they seemed to work, but my phone keeps missing events. I've come to the conclusion that __I only get notifications for events created on the Galaxy but not for those created on my old phone__. I currently have both the Samsung and the Google calendar app installed on the Galaxy and both behave in the same way (either both or neither send a notification). I also made sure that "Notify on this device" in Google Calendar is checked. I can see all the events I missed on my new phone (so the cloud syncing must have worked) and they all had notifications set for them. In fact, when I boot up my old device __I DO get notifications for all the events I missed__ via the built-in calendar app. So: How can I receive notifications for events created on my old out-of-use phone on my new phone?

I prefer Google Calendar over Samsung's built in calendar app on the S4, for notifications. I don't need to remove the latter, and can't seem to; I just don't want it to display notifications. So I change the relevant settings, but periodically they revert. I completely turn off notifications in S Calendar (no tone, no vibration), and turn them on in Google Calendar (with a specific sound and vibration and popup notification). In Google Calendar I also turn on "Show week number" and set "Week starts on" to Monday. After some testing it seems these settings stay in place for as long as the device remains on. After turning it off and back on again, all of the settings in both S Calendar and Google Calendar, including the ones I mentioned not related to notifications, have reverted to their defaults (with notifications ON from S Calendar and OFF from Google) with the exception of the tone that I set for Google. I'm fairly sure that having my phone turned off and then on again is exactly what happened each previous time I've noticed that my settings reverted. I've looked at this post, and none of those solutions (for non-rooted phones) work; the settings still get reverted when I change them, and Samsung's calendar can't be turned off in Application Manager. If both calendars are having this issue I'm not even sure removing S Calendar would fix it. A commenter on the first answer there seems to have the same issue, apparently since a recent upgrade. That may be the case for me too, because I bought this phone a year ago, but now both the device info and the app info for S Calendar have Android 4.4. Why would these settings be reverting on every restart? How can I fix this, besides just not turning my phone off?

I use a Samsung Galaxy Note. I am noticing that each time I make, receive or miss a call, an entry is made in My Calendar, with the details of the call, incoming or outgoing, phone number etc. Every call made / received in the phone log has one calendar entry, making the calendar totally unusable. I am not able to find which application is doing this. Is there any way I can stop this entry from being made for each call? Alternatively, how do I identify which application is making this entry, by looking at the calendar entry?
