NitroKey disappoints me
This feature isn't even only in the Qualcomm 630 chipset, it's in practically all Qualcomm devices. Some third party Android roms go as far as to obscure the IP address of your phone by proxying this http request with another server. The rom they have tested obviously didn't.
This feature is not even limited to Qualcomm devices, this practice happens in practically all devices that have both GPS and [Internet] because people don't like waiting very long for their position when launching their navigation software. The NitroPhone has their GPS provided by Broadcom chips instead of Qualcomm ones so obviously it won't make the same HTTP requests, doesn't make it any more or less secure though.
