I bought a 43" Samsung Smart TV TU8500. After setting up the TV and apps, I started getting a random notification sound from the TV. It happened regardless of what I was watching, or which app I was using.
After some investigation, I narrowed it down to the presence of one of our mobile phones. If the phone was in range of the TV and home router, then the TV would give off random notification pings. If the phone was taken out of range and the TV was switch off, then back on; the notification pings stopped. Bring the phone back into range and the pings would start again.
The only difference with this particular phone (both mobiles are Pixels), was how I setup the YouTube app. For this mobile phone, I used the mobile YouTube account, to link directly to the TV YouTube app. On the other mobile phone, I registered the YouTube account manually, via the YouTube activation code.
It would appear, that if you connect your mobile device directly to the TV. The TV will reestablish that connection, whenever the mobile device is within range. The notification pings, could be the periodic wireless handshakes, performed by the TV and the registered device. This would appear to a bug within the software, as any handshake pings shouldn't generate a sound.
I solved this problem by:
- removing the YouTube account, that was linked to the mobile phone.
- deleted all external device entries from:
Settings->General->External Device Manager->Device Connection Manager->Device List
- Switched the TV off and then on.
I re-registered this mobile YouTube account manually, instead of linking it directly. This has solved the problem of random notifications for me.
