Google's Pixel 2 and Pixel 2 XL have had problems since they were released, and some users complain that the included headphone converter will not work after various problems such as burning screen, call noise and operating system are not installed.
In the new generation of Google Pixel, Google canceled the 3.5mm headphone jack. If you need to use 3.5mm headphone headset you need to use the USB-C converter, and recently there are users that USB-C converter can not be used, even if inserted into the phone USB-C jack, the phone speaker will always play the sound.
After testing, most users restart the phone after the problem has been solved, Google has now paid attention to this problem, but did not give the perfect solution, that is due to third-party interference caused.
Although Google has not yet given a solution, but for now, the scope of the problem is not significant.
