Software updates and broken Pixel features have been an iconic duo for years. Time and again, we've had several instances of some feature or the other breaking due to a seemingly harmless software update. Only recently, some Pixels started shutting down randomly. It is unclear as to what triggered the Pixel 3 shutdown, but some people speculate that it is a software issue as replacements did little in the way of mitigating the problem.

Now, another problem seems to have emerged for Google Pixel 2 users. According to several reports on the official Google Product Forums, several Pixel 2 units are experiencing intermittent Wifi connectivity after installing the Android 10 update.
