A few months ago, Google Nexus 6P and other Google phones started receiving Android O. This was the first developer preview.
As at the time of this writing, the Nexus 6P and co. are already running the third developer preview version. In fact, those who have nothing to do with app development can simply jump into the public beta version of the same OS, but before you do so, note that this is not a stable version and in the process of using you might encounter some issues in performance. Android developers need no lecture on this, though.
According to some people who are running the latest Android O developer preview 3 on the Google Nexus 6P, the device is experiencing some connectivity issues. Apparently, the phone is unable to connect to a Wi-Fi hotspot, but it only shows it’s connecting and this process never ends. Instead, it stays at “Saved” with no connection at all.
This is what usually happens when you have entered an incorrect password for the Wi-Fi router, however, this isn’t the case with the current Nexus 6P issue on Android O. There are others who are even reporting that the connection status suddenly changes from “Saved” to “Disabled”. One Redditor notes that making some tweaks to options under accepting certificates takes care of the problem, but this will obviously not work for everyone.
Another user adds that they have experienced this issue on their Google Nexus 6P before with Android O developer preview 2, but up to now, no viable solution has been pushed forward, maybe because the issue is somehow limited. Doing a Network Settings reset solved the problem for some, but this should only work for those who received this developer preview as an OTA update.
In short, there isn’t any known solution to this issue. With the current Android O still a developer preview version, it gets even tougher when it comes to pinpointing the source of the issue. But hopefully, the next update that the affected Google Nexus 6P users receive will take care of the issue and any others that you might be experiencing.
