I have updated my nokia 5 with stable oreo. But now i have new problem, i cant change notification tone in whatsapp, after i change it revert to default. Does any one have same problem with me? And does someone have solution?
Go to Settings->apps& notification->app info->WhatsApp->app notification->chats->group notification or message notification-> sound.
Now choose your preferred notification sounds.
From Here you can change your custom notification sounds...
