Unidentified sound / vibration notification

XIDIMAPI

For about two weeks, I have been getting a sound / vibration notification about ever 90-120 seconds. Can't find out what's causing it. I've shut down notifications from all apps and everything else I could find. Apparently no System Log for Androids. Tried shutting down and about to try running in Safe Mode (everything else works perfectly) but even if it doesn't malfunction in Safe Mode, I'm not sure how to troubleshoot what the problem is and fix or remove it. Has anybody else encountered this?

XIDIMAPI, hearing that your device is experiencing issues with its sound/vibration for the past two weeks is certainly reason for concern and we'd really like to help get this matter resolved for you. I also appreciate the troubleshooting you've done so far. Can you tell us what make/model Android device you have? In the past two weeks have there been any recent changes with your device? (e.g. software update, new apps downloaded, etc.) You can check to see any app updates from your Android phone by accessing the Google Playstore and following these steps: 1. From the Play Store Home screen, tap the Menu icon (located in the upper-left)  2. Tap My apps & games.
