Im still having issues with getting a fix indoors, it really doest matter if Im close to the window and how big it is
Outdoors it seems to be a different matter. Fix comes within few seconds and works almost flawlessly. I tested it with PureMaps Google maps (Car) and with MeeRun (While running of course). AccuracyI is very good and collected data (throughout the run for example) seems correct as I have many different .gpx files to compare
Still, you may have let’s say hardware issue there. As Xa2’s seems to like falling apart. There are many connectors and antenas. Recently (Before applying the patch) i had mine stripped to pieces and cleaned very thoroughly. Than i glued it back to one unit and it seems to hold on. As i mentioned Im running a lot and it doesnt hurt my phone anymore. You should consider this as well, I mean cleaning it inside and gluing carefully as it seems that factory glue looses it strenght over time.
