    Last night I turned to Google Maps for the first time since switching from an iPhone 6s Plus. I was used to instant satellite fixes and precise positioning on the map. Instead, my s7 edge placed me hundreds of meters away in the middle of the Tiber river. As I drove, fix updates were intermittent and wildly fluctuating. The device proved unless when walking, too. I've checked to make sure that all location features are on.

    Anyone experiencing similar issues?

    Thanks.

    GPS on this phone has been way more precise than my Note 3 ever was. And faster locating the satellites also when I turn it on. My note 3 would take a good minute to get a location and then during the trip it would flake out and stop working for a good 30 seconds from time to time.

    Interesting. For me, Google Maps was wildly inaccurate and very slow to update, if at all. Wonder what's different? Hope it's not a faulty GPS chip.

    Hundreds of metres...how about thousands of kilometres away. Google almost put me in the Tiber river once, which is not bad going considering I was in Hong Kong at the time. LOL. But that was WiFi location, rather than GPS, which has always been exact for me.

    Baidu Maps is always spot on.

    Someone suggested it's an issue with the compass becoming uncalibrated on startup. I entered *#0*# and my compass had a black circle with redline and 0. When calibrated, it changes to a circle with bue line and 3. Now testing to see if GPS performance improves.

    I thought GPS uses the time it takes beams of radio waves to reach multiple satellites to figure out your location. Not the compass.

    Yea its nothing to do with the compass lol. I'm in the UK and I usually use wifi to locate myself, which works pretty accurately. I guess its dependent on your country location? weird.

    Apparently the GPS chip/software uses information from the compass to enhance positioning. I've read that it was also a problem with the s6 and may be Exynos-related. Folks with SD tell me they do not experience a problem. But, I don't know for certain.

    This app is very good and will give you the real scoop on what your GPS is doing. The app also allows for you to trigger the clearing of AGPS and updating of AGPS. I have used this app for around two years now and it is very good.
