For over 2 weeks I've been having mobile data and wireless issues both of my Nexus 4s. This started prior to the v5 rollout. My phone was upgraded to 5, my wife's is still on 4.4.4. The phones had been just fine until one day after some pre-v5 updates, we both started experiencing intermittent problems: mobile text and data would drop and not reconnect, I could not connect to some public open wireless networks that I had used before. Texting worked on boot for a few minutes to 30 minutes, then it shut down. Interestingly, I was in the Phoenix, AZ area last week and had no problems. Back home in western NC these issues persist on AT&T. I tried every APN I could find, changed the battery saving settings, and even flashed a couple of earlier radio/modem firmware. I did see an article today that v5 upgrades have been suspended by Google due to similar wireless issues in Europe. Mobile data was not mentioned. If this should be posted elsewhere, please advise. In short, it appears to be some revised code that may be sensitive to carriers and their site equipment.
