[Samsung Epic 4G Touch] AbsolutZeroGI:
Seeing the "similar threads we found", I see that I'm not the only one having this issue and we're not the only phone having problems.

Turns out there's a known issue on Google Voice where if the customer adds a line, subtracts a line or screws with their service in any way that requires an activation of the line that's on Google Voice (like an upgrade...yknow like we all did :P), that Google Voice can fizzle out. Basically, it automatically unchecks the box that says "this phone can receive texts" which prevents your phone from receiving texts. This also changes the setting on the phone app to route texts through your stock messages app again. This will step-by-step you into changing them back.

Well I got mine working again, and I'd like to share how I did it so maybe it'll work for you.

**NOTICE**

This is for one line on Google Voice only. Apparently this won't work if you have multiple phones attached to the same Google account.

Okay:

1. open up your web browser and go to: voice.google.com. Then open up google voice on your phone.

2. in the browser, click your phone number (top right corner). A menu will pop up and you'll notice the "this phone receives text messages" (or however it's written) is unchecked. That's the bug, it'll uncheck itself every time you go to that screen. Also, when this box becomes unchecked, it actually changes a setting in the Google Voice app on your phone to route texts through the stock messaging app again (annoying).

3. Check that box so that it's one (don't close out of the browser yet, leave it on that screen)

4. Then, in your google voice app on the phone, go to menu > more > settings > notifications and sync where there's a drop down menu specifying whether you want messages received by the messages app or GVoice. choose which one you want (i'm assuming if you're here, you use GVoice). This is the setting I mentioned that it changes in the app (all the way back in step 2).

5. Now you should still have GVoice open in your browser. If not, you follow directions badly and need to repeat the process. If yes, you should have the unchecked box checked (when it wasn't before) and the setting on the phone app itself changed back to normal.

6. While the browser is open, have a few people text you. You should now be getting texts and voicemails delivered to your GVoice account again. This isn't necessary, but to test to make sure you did it right.

Last: once you re-establish that "connection" close the browser and never go back to that options page again (it'll just un-check that box and change that setting on the phone and make you do this all over again). Now your GVoice should be working properly.

*addendum*

If you're still have trouble after this. Go back to the options page where you started, check the box, then uninstall/re-install Gvoice on your phone and go through the set up again...then continue following the steps.

*addendum 2*

If this fails, then disable GVoice services with Sprint and set them up anew using the app on your phone (like you did the first time).

Don't worry about the "can't do whatever", just hit "skip".

Then follow the steps above.

Hope this helps, I know us GVoice users are minority but hey we need people to figure crap out too :D
