iPhone 7 GPS constantly changing in Maps

iPhone 6 the bests think

I totally agree with you! I don't think there just few defected devices. There are a lot but only their users just don't know about it because in order to aware of the problem either you need to either use gps to drive or navigate or use such a running applications. But I also think that we need Apple to hear our voice more strongly. Otherwise we'll keep suffering from it. I return my 7 plus and using my old 4S till they solve whatever the problem.

To me is getting worse.

Today is jumping sometimes even between cities. I couldn't do my workout and also I couldn't use the navigator.

It should be a real hardware problem; and a pretty serious one considering that my friends with 2 different brands (Huawei and Samsung), payed less than 200€, did a good job compering with mine that has been payed more than 1000€.

Coming back home, really upset, I did this video: https://www.dropbox.com/s/8zt4xxhp6ek4jh0/IPhone.mp4?dl=0

Yesterday I tracked my run with Strava on the iPhone and the Training.app on the Watch. I activated airplane mode on the Watch so that it uses its built-in GPS. The result was dramatic. Whilst the Watch measured a distance of 17.45 km the route measured on the iPhone was 20.1 km!
On the other day I did a test run on a track, which distance I know. I tested the GPS of the Watch and the tracked distance was just < 100m off the actual distance. So, in my opinion, there is no doubt, that the distance the Watch has shown is more reliable.

I also deactivated LTE and Wifi on the iPhone.

I have the same too.Do you write to Support?

Did Christmas come early?? I just installed the iOS 10.2 update and quickly checked my maps apps to see if there was any change, and so far everything looks stable! I'm going to give navigation a try to see how it does.

I'm curious to see if this update helps any of you guys out also. Please reply if you see it fixed now. Thanks!

I have same problem after the update 10.2

I'm afraid I cannot reproduce the same results.

My maps are still jumping around and while it first looked like it was jumping a bit less, after some minutes (outside) it was still "confused" and jumping in the same pattern as before the 10.2 update.

I then opened the Waze app which has been completely broken for me with "No GPS. Showing approximate location." which means navigation doesn't work at all and that's also happening after the 10.2 update, so for me it's status quo.

I purchased the .99 app GPS Diagnostic, which shows constant GPS signal status for each available satellite. Since then, I have seen quite clearly how sat reception hovered around the 50% range for all sats, which gave me around a 200 foot accuracy radius or worse. At this level of accuracy, it is no wonder it could never pinpoint what road I was actually on, which prompted Maps to keep trying to reroute me.

I placed a call to Apple support, this morning, to discuss this issue and to see if they had any new information/solutions. While going through the setting we discovered together that iOS 10.2 was out, so the tech suggested that after the call I do the update and see if that solved the issue. It did not.

However I have made one discovery, which may be of some use to a few of you. In my case I have been able to confirm that this issue largely goes away when I turn off the bluetooth radio transmitter I purchased a few weeks ago, so I could listen to music through my car stereo. When I turn it off, the sat reception climbs up into the green (between 75% and 100%. Not instantly, but obviously, and over about a 10-20 second period. If I turn the bluetooth device back on again, reception immediately dips down again. I'm not 100% certain, because reception strength is always moving up and down to some degree, and will occasionally dip even when I do nothing. But at lunch today I drove a few miles, navigating to a restaurant using Apple Maps, after I had updated my iPhone 7 to iOS 10.2, then doing a hard reset. It couldn't find my exact location most of the whole way there, and sat reception was low. On the way back, I had the bluetooth device turned off, and it navigated me back to my office with not a single hitch or hesitation.

This is not a definitive test (only a couple of miles and only 1 test). And this is clearly not a solution. But for me it could prove to be a workaround -- to be sure, one that is unsatisfying, as it means turning off news podcasts or music when I want to navigate, but at least I CAN navigate, now.

I'd be curious to find out if this proves to be true for anyone else.

YEB I UPDATE TO IOS 10.2 WOW! PERFECT GPS ON GOOLGLE MAP SO PERFECT!🙂

THANKS APPLE TEAM AND ALL HERE😁

Well, I tested my iPhone 7 all day today and the GPS is working just fine now after updating to iOS 10.2. I finally got to use Google Maps and Apple's Maps to navigate and Runtastic Pro to go for a run. None of the other updates—10.1 & 10.1.1—fixed it, but 10.2 did. My GPS issue was very noticeable. It wasn't just inaccurate by feet, it was off by blocks or not working at all when driving.

But, yeah, it's back to normal now after months which means that it was a software issue and not hardware one. I'm glad held out and didn't exchange my iPhone for another.

Good luck to the rest of you.

After installing 10.2, I tried walking to work with Strava running on both phones (6 and 7). Same as before: The iPhone 7 track is jagged and veers more often off the actual track than on the iPhone 6. A 1.9 km walk was measured as 2.5 kms 😟

Confirmed.

But I believe that something happened to me lately (on Sunday): probably something has got broken and so I decided to book Genius bar that is free only on Sunday 😟; they said that the device shall be changed (hopping that they have already found the cause of hardware issue).

Set.

Whatever the iOS10.2 update did to my device, it did not solve whether the gps issue nor the battery issue.

I will observe this one or two days more before I definitely let apple swap my device...

Confirmed: turning off my FM transmitter in my car returns GPS functionality to its former glory. Drove to and from work (15 miles each way) with zero issues.

Interesting note: it doesn't matter whether or not I turn off bluetooth on my phone. The actual transmitter is blocking the signal when it's on, even if bluetooth on my phone is off.

I realize this is not going to be a solution for most of you, but I think it's an important clue. Clearly, something has weakened the satellite signal for all of us, but in my case it wasn't weak enough on its own to affect navigation. I can tell you I have had this FM transmitter much longer than I have had this issue, so something changed -- it didn't used to affect navigation and clearly now it does. I'm going to test my old FM transmitter, which does not use bluetooth at all, but connects via the headphone port. I'm curious to see if the actual radio signal is causing the interference.

Obviously, many of you are going on runs or rides with your phone and don't have any other technology near you that could be affecting the GPS signal. But for the rest of you, perhaps something in your car or maybe even you Apple Watch could be the thing that blocks your weakened signal. Perhaps we can find a pattern.
