Problem with Gps in M30s

from last month the gps in my phone is not working. I bought this phone on the first sale at that time it was working perfectly but after a month it suddenly stopped working or if it is working it's extremely inaccurate. I've compared with other phones at the same location that worked but it has not. I also error reported to samsung they are consistently denying this issue. they are asking me to go in open space and test now if I order food online am I supposed to go outside of my home a book? when I'm driving or inside a train or bus am I supppsed to jump out of the vehicle to use gps? I've done every kind of remedies that could have possible.. cleared data of google maps cleared cache of the device from recovery but nothing is working. I have tested with an app which shows the reception of the signals from the satelites 'gps test' in which it failed every time. But when I purchased this phone this problem is not there at that time O used it inside buildings, trains, every time it worled perfectly but now it's so inaccurate and sometimes completely not working. I don't know whether this is a hardware fault or a software fault. I am attaching some screemshots of the problem
