From Google's Location Source and Accuracy page: Data sources The following location data sources may be used to derive location: GPS: GPS accuracy can be up to several meters depending on your GPS signal and connection. Your phone must support GPS, have it enabled, and allow Google Maps access to it. WiFi: WiFi (wireless network) ...

That's most likely not a GPS position, but rather a WiFi hotspot. Google's location service makes use of different identifiers: GPS WiFi hotspots Cell towers While GPS should be quite accurate (bad conditions might give lower accuracy, but usually shouldn't place you too far off), and cell towers usually are not moving -- WiFi hotspots may exactly do that. ...

If you click on the dots, you will get the time it recorded you there. If it is 35 miles away, and it is within minutes of the previous location, then it would be impossible for you to be there in less than 1/2 hour. I also agree with the others about the Wi-Fi. I was traveling in Michigan this week, and there is one point in Las Vegas that shows up just ...

Summing up all the comments: Will Google save the locations? Definitely. As soon as you want to use the more battery-friendly “network based location” you have to agree that Google collects your location data “to improve its services”: click image for larger variant So “location history” and ”location report” are meaningless in this context. As it was ...

Here are the basic technologies for location on an Android device: GPS (Global positioning system) - uses satellite signals to determine location without external request, high accuracy (~5 m), high power, high time to first fix. WiFi - uses WiFi scans and requests location from Google (possibly over cellular network), medium accuracy (~50 m), low power, ...

There are many possible reasons that places could show up inaccurately in the Google Maps tracking. If your device is indoors, it will not have a good GPS signal (or possibly have no GPS signal at all) and will have to use less accurate location methods. Each of those methods has problems, some of which are discussed below. If your device is trying to ...

GPS uses best estimate statistical methods to guess at the location, and sometimes the calculation goes wild due rounding errors, lousy code in the GPS chip, etc. etc.

Latify in the Play Store does the trick.

Google has a weird mix of app settings, device settings, and a website to manage location permissions. I've found that the easiest way to access most of it is through Settings → Personal content in the Google Maps app: As you can see I've gone through those one-by-one to disable all use of my location info by Google. You might also need to go to ...

If the device came into possession of an unauthorized person than you should be more concerned whether the device's software integrity is intact or not. Although Android since Nougat informs the user if boot process is compromised (only when booting the device), one can employ a minimal cross-check on their own. Some root checker apps attempts to ensure ...

I've had similar mysterious activity showing up on my account in the past (albeit, several years ago). It's important to remember that your Google account, and thusly your usage history, can be shared across multiple devices, including a mixture of desktop, laptop, mobile, even TV and assistant enabled devices like Google Home. I spent a moment going over ...

The "start driving" feature in Google Maps saves your position every 15 seconds. (That's what I do) Using any other app to require exact gps position in background is less accurate (same accuracy but less frequent data points).

"Start driving" in Google Maps increases the frequency to 15 seconds per sample. Then send it to background, turn off the screen. It consumes more battery but not much.

Do you have GPS turned on during the day? If not, google locates your position over your phone's network, which is inaccurate. Here are some ways to improve your location history: find and improve your location's accuracy

Other than what @MosheKatz said in his answer another point you may have to consider is that whether your Google account is being used only on your Samsung Galaxy Core Prime. I was surprised to see my timeline jumping across countries and quickly realised that my relative who has borrowed my Nexus tablet is producing these results. Being a close relative I ...

Do you use your Google account on more than one device? Or do you turn off location and your cell data and connect only via wifi? If you were connected to WiFi on your phone, or another WiFi or ethernet connected device logged in with your Google account, Google may have assumed your location was the location of the IP address you were using (which isn't ...

So, after my vacation I know for certain that it is possible to record the positions without an open internet connection. As soon as an app requests a position (in my case an offline map app) this position will be stored (cached) by the location services from google. The positions will be transferred to google as soon as an connection has been established. ...

Sometimes it gets disconnected internally. So the app is non-functional. You can always uninstall then reinstall the app. That will reconnect it internally. I see chatter in the comments about locations and time zones but that is not in the question, so my answer stands as written.

You can check the internal Android log logcat to see WiFi connectivity changes (and many different events) from the last few hours or so. To do that, you'll have to enable USB debugging, download ADB, install an ADB driver for your phone on your computer, connect the phone with a USB cable and run this in a terminal: adb logcat -v threadtime ...

When this occurs, send feedback to Google from Google Maps, with your location enabled. Open Google Maps. Touch the menu (three lines). Touch 'Send feedback'. Touch 'Report location issues'. This is what Google requests that you do. More background: The Washington Post reports that location as reported by your cellular provider can be inaccurate. ...

More accuracy is technically achievable, but at a cost. Keeping GPS turned on and recording positions more often draws power, making the battery run down more quickly. That wouldn't be appropriate for something that always run in the background like Google Location History, but there are other location tracking apps (such as running apps) that let you choose ...

One reason could be that that location was determined from a WiFi access point, which had been previously moved from Japan to somewhere near you. Google registers the location of each WiFi access point Android devices are connected to (if allowed in settings) and uses these to obtain a location when GPS is slow or unavailable. Unfortunately it takes some ...

Go to settings > location > mode and select high accuracy. This will ensure that the gps is used for location.

Not sure if this really qualifies as an answer, but since I don't have enough points to comment and I do want to contribute what I've discovered about this problem, it'll have to do... I've had a very similar sounding problem for the last 2 weeks or so with no obvious trigger in terms of app or firmware updates. My location history has gone crazy with some ...
