How to check for gps sensor in android phone?

Question

Android

I need to have gps on my phone. But he can't find satellites. I reflashed it, rooted it, registered gps.conf, tried to speed everything up according to different manuals from the Internet, as a result, there is no connection in tens of minutes in open space. How to check the presence of a gps antenna without disassembling the phone? What kind of lspci is needed, but for a phone that will show all the information about hardware and gps.
