GPS not working after update to IOS11

I tried the sim method but it didn’t work for me 😩 just wondering does it matter if you have your mobile data on before reinserting the sim or there are any other settings that might have effected it?

Also I only downloaded the GPS diagnostic app a few hours ago and I had a good 5 mins straight with green bars but since it’s just been reporting no satellite for approximately 20 minutes

I'm no tech, but I strongly believe that this entire issue is either strictly a software issue where iOS 11 altered the entire scope of how iOS handles communication between the phone, the OS and the antenna, including power management (throttling to benefit battery life, etc.) -OR- antenna hardware that deteriorates in functionality over the life of an iPhone 6/6S (or any other iPhone that uses similar materials in the antenna) -OR- a combination of both things, or both things in overlap.

Whatever it is, it's evident that it's prevalent for many users, including those with iPhone X handsets, and it's evident that Apple isn't ever going to acknowledge directly.

Personally, I was hoping to keep my 6S until Apple completely discontinued all support for it, but based on how unreliable the GPS has become, I'm going to finally upgrade in September with whatever they offer up.

You have an accuracy of 657 feet at the time 21:33:10

then a good signal about 48 seconds later.

What happened during those 48 seconds?

I mean, did you check? Could it have recovered during those 48 seconds?

If the signal reception remained lousy for almost a minute, that is a concern.

Mine "flickers" up and down constantly, but it never stays at that low level (e.g. 657 feet) for more than 5-10 seconds, which is good enough, although not ideal, for me.

As far I’m aware nothing happened to cause the change in gps signal within those seconds. After those fluctuations I showed above the app consistently showed ‘no satellite’ for a good few hours. Then this morning I drove to work and checked and I have good signal again?? The good signal reports never last for longer than approx 15 mins unfortunately so I think it will be back to no satellite within an hour which is annoying but I’ll keep checking

Thanks for the update. I keep wondering whether the SIM reset (done at my own risk) was just a fluke for me, but then I hear from other people like you, which suggests it wasn't. I have not needed to do the procedure since mid-May, though I am sometimes tempted to try it again because the time to first fix can be pretty long on occasions (over 30-40 seconds, especially if I don't stand stationary outside until it gives me a proper GPS-based position on the map). While accuracy after the first fix is pretty good, the start-up time is far from ideal. Not satisfied. I didn't pay all this money for an iPhone X to get inferior performance to my old phone's!

Hi there, If you are still struggling with that problem, then I can recommend you a solution. You should go to the settings, then “Google Maps” and enable the “Background App Refresh”. If that wouldn't work then go to the settings as before choose the “compass” and turn on the “True North” option. If you still would have some problems with it, then I am sure that you will find a solution in this article.

Update:

Since doing the “SIM trick” back in May (do so at your own risk; some sites advise against SIM insertion/removal while phone is on), I have been able to use GPS apps on my iPhone X with sufficient accuracy.

However, finding the initial location i.e. “the time to first fix - TTFF” has grown gradually longer over time. Yesterday, it didn’t work at all at the start of my jog, and when I tested it later, it only found a fix after more than a minute of standing stationary.

I decided that I had had enough and tried the SIM trick a second time. It worked again! The TTFF is much shorter now.

Nothing has changed on the phone as far as I can see. Same iOS, same apps, same carrier, same location. My wife’s iPhone 6S has the same iOS, and testing apps, and uses the carrier as my iPhone X and is tested at the same locations, BUT her GPS has functioned perfectly the whole time, with no delays etc! The only difference is that I have some additional apps such as Motion X - I don't see how that should affect the functioning of the phone, and if it is, then Apple is responsible, as Apple checks 3rd party apps downloaded via the App Store.

I have to do this procedure every time the lag on my GPS/A-GPS system occurs, while my wife doesn’t. This suggests there is a software or hardware design flaw that has affected a large segment of iPhone users for whom the SIM trick has worked. The only other solution was factory resetting the phone when I replaced it with an identical iPhone X but the problem soon recurred even when I manually set up the phone from scratch!! In these cases, I strongly suspect there is a software or hardware design flaw related to the cellular network/SIM card that seems to be affecting the A-GPS function

GPS is a pretty basic function to get wrong for a high-end device as expensive as the iPhone X. This issue has dragged on for ages now - look at all the posts in these forums and elsewhere - and yet there has been no public acknowledgement of it. Not even a clear reference to the problem in iOS update notes as far as I am aware - someone please correct me if I am wrong on that.

Have you turned off WiFi?

Is WiFi on or off?

I am having the same issue, GPS not working on iPhone 6 on any mapping apps, after IOS 11 update. Please fix it apple!

I have the same problem, T-Mobile iPhone 6 no god showing for waze and google map and maps can’t find my location.i tried everything no luck. Any help will be appropriated

Hi,

I just did a soft reset on my phone and now the GPS started working again.
