Not fixed here.
I can set all the settings how I want them = No Vibration, My tone of choice etc. and in anywhere from 10 minutes to a few hours, they all change back to the defaults.
What makes this really annoying, is when they change, they also deselect GV incoming phone calls and sometimes the Google Voice text messages themselves! The phone call part I can live with as they wont let you change the inaudible ring tone but when it changes the calls don't go back to GV. Unless, On a PC you have gone into GV settings and checked to have calls sent to the phone as well as chat. keep it like this you get dual notifications and ring tones on calls. I wanted to use Hangouts for GV phones so I could distinguish ( with a Ringtone) who they are coming from - AKA Business line or Personal
I have tried every possible combo of settings with GV installed and on / Off, Uninstalled etc.
Nothing works.
I only want to use Hangouts so i can have MMS with my free GV texting, other than that, You can have the whole app.
Trying to get everybody I text to switch to hangouts is an effort in futility. As they are each trying to get everyone to switch to ichat, whatsapp, skype etc... And i refuse to pay Verizon for texting. I pay them for Data - Which is Enough. If I change my plan to free texting Unlimited mins. I lose Unlimited Data and my bill almost doubles!
All we need is MMS on GV and it;s perfect
