Sametbayram , via OnePlus 8 Pro , Dec 2, 2021 : Every Couple months, our family (3 OnePlus phones) 2 OnePlus 8 Pro 1 OnePlus 7 Speaker issue, this is a general one; happens t9 come every 5 to 7 months. Plus, WhatsApp, Imo, Instagram kind of apps no sound or very little sometimes. I bet most people have same because 3 phones cant have it. There must be a new update otherwise it is bothering. Before I forget, having issues with MB Cars Bluetooth connection.
