B. The cell phone had lost service to the carrier.

The most likely cause of the phone's GPS failure is B. The cell phone had lost service to the carrier. Many modern smartphones use a combination of GPS, Wi-Fi, and cellular signals to determine location. If the phone loses cellular service, it may not be able to accurately determine its location, especially in areas with weak Wi-Fi signals. Here's why the other options are less likely: A. The cell phone was in conservation mode: While conservation mode can affect certain features, it's unlikely to completely disable GPS functionality. C. The cell phone received a firmware update: Firmware updates typically improve device performance and stability. They are not likely to cause GPS failures. D. The cell phone had overheated: Overheating can cause various issues, but it's less likely to specifically affect GPS functionality. Therefore, a temporary loss of cellular service is the most probable explanation for the phone's GPS failure. GG

Conservation mode (or battery saver mode) often limits or disables certain functions, including GPS, to preserve battery life. When the phone's GPS stopped working and later resumed, it is likely that the conservation mode was temporarily activated, causing the GPS feature to be disabled in favor of saving power.

My phone did overheat once in the car, and its GPS did malfunction... More an issue with the phone than anything. Still, the scenario's best answer is B.

??? Why would you ASSUME that there was some kind of overheating issue? Pro tip: With these tests, NEVER ASSUME anything. Go by what the questions literally state. More than likely, the cell phone lost service is all.

GPS signal comes from GPS satellites and cell towers only fine tune that. GPS would continue working but may not be pinpoint accurate. Not to mention the use of GPS on a phone can cause overheating. I am thinking the cell phone overheated since it mentioned the tech was working in the field and his in car GPS still worked. I go with D.

This indicates that the tracker is currently unable to show you real-time, accurate positions. The tracker may be switched off or the battery may be empty. It could also be because the tracker is struggling to maintain a connection to local cell networks, or unable to detect accurate GPS positions.
