Curious to see if anyone has my issues. When I got back from Italy (used the international roaming there) my phone worked fine for a couple days. Then it would connect to LTE and evdo but not 1x so I couldn't make phone calls. I took it to the store after flashing back to full stock (which didn't fix it). After I told the rep my issues using the technological terms (like ehrpd) she told me that I was talking about gsm and sprint is CDMA. She and the lead tech proceeded to tell me I was still in "international" mode and that I needed to get my phone locked to the network again. I tried to explain that nexuses don't come locked and that wasn't the problem because it worked when I got back. I went home, unfixed, and ended up fiddling with it and changed to ART which magically fixed it for a couple days. Then I decided that I would try the developer preview and it has fixed everything. Thoughts?
