For example, my wife and I only had call issues at our house, where both of our devices registered -115 dBm of signal strength. This was not a problem for our Pixel 2's. When calling from my job, the issue was far less frequent and the signal strength is approximately -100 dBm. Finally, we received a signal booster from our carrier for the house and the call issues went away completely, measuring -80 dBm.
Based on this, I can only assume the Pixel 3's hardware is not holding on to signals as well as other phones and I need your help determining if the problems go away above a certain signal strength threshold.
1. Open the stock phone dialer app
2. Enter the test menu by dialing *#*#4636#*#*
3. Select "Phone Information"
4. Find the "Signal Strength" line and report the value you see.
Once again, please only list yours from an area where you experience consistent call quality issues.
