Here is what Stark support says regarding this. I don't understand why 4G is required to record GPS data:
Thank you for contacting Stark.
If you have 4G data the phone should collect this information, it's possible that at the time you were using the VARG the 4G connection was poor, in which case the phone can't collect the information.

Can you please check the wireless charging module connector located behind the number plate inside the connectors box. Ensure it's clear of debris or oxidation. Also check that none of the wires going into the connectors feel loose. If the wires are loose, the vibrations while riding may cause the bluetooth connection between the Stark phone and the bike to be lost and possibly the reason why your rides are not being recorded.
