In this case the best thing to do is the Hard Reset to see if it will solve this because if it was not you who did it or not alteirou anything in the settings, it must be a system bug, Hard Reset should solve this.
Before you can do the procedure you will need to save your files, contacts and remove the Google account, below the step by step of the restore: Settings: Back up and reset > Factory default restore > Reset device > Delete all. If the problem still persists, we advise you to take your product in technical assistance to be analyzed.
Acabou que a restauração de fábrica resolveu o problema só nas primeiras 2 ligações que recebi. Só não tô querendo ir na assistência técnica e ficar sem celular por que eles pegam e ficam com ele lá pra analisar. Não consigo achar mais ninguém que teve o mesmo bug que eu. Celular caro desses e vem com bug. 🥲
Turn off all the sounds and set it to Not disturb, and see if it still on. Try to change the call & notification sound. But if persist try doing a reset to a factory default.
