I ordered a replacement nexus because people keep telling me the voice quality on my nexus sucked. After getting a replacement device it is worse than the original defected device. My replacement will not keep a connection on 4G, voice or data. When trying to surf the web I lose network every 2 or 3 minutes. When making a call it will drop with the same time frame. My original device never once had any kind of data issues. I'm having a 2nd replacement sent overnight with Saturday delivery. How common is this? I'm now worried I'll have a hard time getting a nexus without data issues. I now wish I would have just dealt with the voice quality issues as it wasn't 100% of the time. Just wondering if anyone has gotten a replacement that was worse than the original, and how common it is for the phone not to work on 4G, thanks.
