Many of you have seen the multiple threads on multiple forums about the call quality issues with the Pixel 3 and 3XL, so I won't dig into that any further. Instead, I am asking if those who have issues can list the signal strength as reported by your device in the area where the call issues occur?

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.

INSTRUCTIONS:
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.

Yes, we know not everyone has the issue. I'm asking that only people who do have the issue to report their signal strength in the area where the issue occurs most frequently. No need to report if you don't have issues at that won't help us find a pattern.

I don't make or receive a huge amount of calls. But have had several reports of poor quality, maybe half the time, in my dining room..

From this location currently it reports the following.

-107 dBm 33asu..

I will test this again directly after a next poor quality call for comparison. Currently on the hunt for a new job, thus expecting a greater volume of calls going forward so would be great to get to the bottom of this.

For reference I use a case, but have not tried any of the other suggestions mentioned elsewhere on xda

Just seems to me that it would be good to know at what threshold there isn't a problem. If you're collecting data it's better to get more than less. It's hard to go back if down the road your theory changes based on the data you're seeing. Believe me, I've been down that road before.

Yeah, i see what you're saying, but if you're not having any issues ever, then your device only skews the data. But if your device works properly at x dbm but doesn't at y dbm, then that would be great to know!

-113 dBm 4G (Telus, Ontario Canada @ home) static, background interference

-62 dBm 3G (Telus, Ontario Canada @ home) no issues

That was taking shortly before I sent my Pixel 3 in for RMA on Jan. 3

Also note Pixel (2016) same location no issues
-112 dBm 4G

Interesting. I'm on Bell and turned off VoLTE (Enhanced LTE services) and I think that static, background interference is gone. I already RMA'd my Pixel 3 for this issue and the second one I got (brand new in box) is exactly the same.
I've never dropped a call. This is my only issue.
