Thanks for the diagram. Based on the location of the antenna and the way I hold the phone, that area is never covered.
I am aware that a plane is a poor reception environment but that is irrelivant because my complaint related to Sony's performance relative to other cell phones with GPS in the same environment. It should be able to perform just as well. The issue is that the way the phone/gps chip/etc is programmed/designed to determine the signal is sufficient to acheive a "GPS lock" is much more strigent as compared to other phones. When using the Sony phone side by side with other much older phones, the Sony performs significantly worse in terms of its ability to acheive an initial GPS lock and keep the GPS lock. When comparing the signal levels from each satellite, the Sony phone seems similar to other phones. It just does not lock. In good GPS environments, the GPS works fine. I have compared my phone to another person with a Z5 compact that happened to be sitting next to me on the plane and we both had equivilant issues. So I do not think it is just my phone.
I beleive this is likely something that can be adjusted in a firmware. Therefore, I am simply asking that my request be forwarded to sony engineers for consideration to incorporate in a future update.
I did not know the appropriate path to submit this request. I tried local support, however, I did not receive any response to my reply. Thus I tried this forum. This is a fix request but I have suggestions I'd like to send in as well. (ie. Real Burst mode from holding down shutter (like on iphone), lower ISO noise, automatic dynamic range level optimization after photo is taken. Full mode Camera2 API support) I figure that Sony will not make changes unless they receive customer feedback.
