I used to have an LG Optimus G and I was able to personalize texts notification sounds, so I knew who the text was from without having to grab my phone. About a month ago, I was eligible for an upgrade and went with the HTC M9. In setting up my phone, I can't seem to put certain sounds with text notifications. Am I missing something? I mean, a phone this new and powerful should have that option. Any help would be greatly appreciated. Thanks!
