Some models of the Google Pixel 2 have inadequate call volume and it is a known manufacturer defect. I use a Compilot 2 with my telephone. I was struggling with this new phone…I could not hear a call. I called Verizon many times trying to get assistance with the issue…they were no help. I finally got to Google…and the representative admitted it is a known defect and they sent me a new phone.
This was a huge stressful issue…I am so glad its fixed!
