I have the LG G2, and for volume and hearability reasons I like to use 3rd party sounds for my ringtone and notification tones... unfortunately, I've never been able to get it to remember my chosen sounds. Right now, but not always, I'm using Zedge... I choose the sound I want and select it in Messaging App settings and in the phone settings... occasionally it will use that sound, but not always or even often, it usually reverts to the default notification tone which I more often than not cannot hear. Also, I only get a tone at all if my phone is in lock, if the screen is open I get no notification sounds at all. That sounds like a setting thing, but I can't find anything specific to that... and, anytime I reboot the phone, the messaging app will remember the chosen tone, but the phone will always revert to it's internal default... is this a bug or am I doing something wrong?
