My son started complaining that when playing Pokemon GO, he'd be in the wrong position all the time while his brother's G2 was fine.
His screen started flickering (a different issue), and since his G2 is out of warranty, I just got him a different G2 off Craigslist. Used, but in excellent shape.
Same GPS issue as the first.
Side by side, his brother's G2 GPS works awesome. Fast connection to satellites. connects to within 10-25 feet accuracy. The 2 G2s with GPS connection problems never really connect or if connected are 55-100+ feet in accuracy.
I tried the cardboard/cardstock fix, and it did not work.
All I saw was the GPS pin to the left of the rear camera (with G2 opened) pushed back
I saw a post about adding a wire to the two pins. The OP commented that the top wire did nothing. So my testing started.
DO SO AT YOUR OWN RISK. (YOU COULD SHORT SOMETHING)
With GPS TEST app installed and the phone powered up and back off, I touched the bottom pin and the GPS connection went from no connection (back was off) to a moderately fast connection to satellites. AND it connected to within 10-25 feet accuracy.
I checked Youtube and this Russian fellow found the same. Same app, too!

Took a stranded wire and tore off the sheath.
There was a little blood as one of the strands poked my thumb. ouch!
Using one of the thin naked copper strands, I did the same thing, and VOILA! good connection.
Unfortunately, when I taped the wire to the back and closed the cover, it stopped working.
Not sure why other than the wire lost connectivity to the pin.
I'm seeing the clips on the phone wear, so I'm weary about opening the back of the phone so often.
But the issue is hardware...specifically the antenna on the cover.
I don't have expertise to mess with the flap on the cover and wire up an antenna.
I don't know what peeling back the black antenna on the cover will yield or if adding a wire is even possible.
The next step is to use headphone wire like the video or solder a wire to the pin. I'll need some KAPTON tape for the soldering to avoid damaging the motherboard though. To eBAY I go...
