I just bought an LG G5 and set up individual notification sounds for multiple contacts. However, the default sound is still the only text noise I hear when getting messages. I managed to get the sound to work by switching from using the default Messenger+ to the plain Messaging app but once I open a text, all notification sounds for incoming texts return to the default again until I exit the app. Any idea how to use the personalized sounds in Messenger+? Or should I stick with Messaging? and why does the sound switch to default after I open a message? Can I fix it to keep using the personalized sound?
