  1. Does the Broadcom BCM47752 chip support dual-frequency GNSS?
  2. If so, does the Galaxy S9/S9+ Exynos variant need a firmware update to enable it?
  1. Find the file /vendor/etc/gps.xml on your device
  2. In gps.xml, find the <gll> section
  3. Replace the MultiCarrLnaMask and MultiCarrRFMode lines with the following (you also might want to save the current lines in case you need to revert these changes):
MultiCarrLnaMask ="L1_EXT_ON | L5_EXT_ON"
MultiCarrLnaMask ="L1_EXT_ON|L5_EXT_ON"
