My eyes desperately need a break from the iPhone so I put my SIM card back to the Kompakt. I keep getting ghost notifications, every few minutes or so. I am sure it’s neither texts nor voicemail. The sideloaded apps I have are calmcast, Spotify, and herewego maps. The latter two I have not used in awhile.
Also of note that in all the previous months I was using the Kompakt, I did not have this happen, so this is new.
Is it the sounds that you have selected for your notifications? OR is a a random mystery sound.
I talked to our team about and this is the most obvious explanation:
1. The “Ding-Dong” Sound (Connection Alerts) The sound you are describing is the system’s default notification for a successful status change or connection event.
USB: When you connect to a computer with debugging enabled, the phone plays this sound to alert you that a data connection (ADB) has been established. This is a security feature to ensure you know a data link is active.
Bluetooth: This is where the inconsistency comes from. The sound is typically triggered when a device connects via a specific profile (like HFP/Hands-Free for your car or Headset profile). However, simple A2DP (Media Audio) connections often connect silently or handle the tone on the speaker itself, not the phone. This protocol difference is likely why your home speakers remain silent while your car (which acts like a headset) triggers the chime.
2. The “Mystery Sound”
If you are hearing this sound randomly without an obvious trigger, it is very likely a brief connection/disconnection event occurring in the background. For example, if your phone momentarily loses and regains connection to a known Bluetooth device, or if a charging cable has a loose contact, the system might play that same “Ding-Dong” to announce the reconnection.
It also comes from third party apps - we do not have notifications tray, so that can happen.
It also comes from unrecognized and unsupported group messages (in older Mudita OS K versions).
