I asked Purism support once, and they gave me a quick response on how to try to connect the antenna better, but I did not dare to take the L5 that far apart. So maybe, I’m suffering a hardware issue, but also for me GPS/Location tracking is still never functioning. For me missing navigation is one of the main issues that I still have to carry my Android device with me too often.
This is what support at Purism wrote to me:
Hello,
Thanks. I spoke to our engineer, she suggested to check first if the GNSS antennae spring contact has proper contact with the frame - this to her is the most likely cause of the problem.
Detailed steps to perform this:
1. take of the back cover
2. open the three screws to open the cover of WiFi / modem
3. disconnect antenna cables and remove modem and WiFi card
4. open all six screws of the frame plus the two screws in the M.2 card compartments
5. before lifting the frame the antenna cables must be removed from the guides in the frame
6. then start in the battery compartment and carefully lift and click out the frame
The GNSS antenna spring contact is a tiny metal part on the top edge of the PCB, close to the rear camera. This metal spring contact must have firm contact with the metal frame.
