GPS Signal Loss Indoors:
Switch to LBS positioning (50-500m accuracy) or move to an open area for GPS.
Battery Drains Quickly:
Avoid continuous use of "Accurate Track Mode"; switch to "Intelligent Mode" for extended standby.
APP/Platform Offline:
Confirm 4G data is enabled and APN is correctly set; restart the device if needed.
