Gps signal lost

[Revtnr]

This announcement coming every few minutes when using any navigation app and the navigation doesn't work pretty much. Checked all settings and all sims to be fine.

I noticed this issue since last update.

Where is the phone located when this happens? Is the phone antenna in an open view and good location to receive satellite signals ?

In fact in my daily job I work with navigation and GPS. So I know a bit about that. Here are a few facts.

GPS receiver needs a minimum of 4 satellite signals to make a position fix. Typically there are a lot more available, although if the phone is in a bad location, pocket, or the antenna is pointing downwards to the ground then it makes this increasing hard.

Ideally the phone should be held with the antenna upwards pointing and with a clear view.

Is it in a case ? Does it still have the same problem when the case is removed ?

If you want to know what is actually happening with the GNSS signals to your phone then there is an app called GPSstatus that can be downloaded for free from Google play.

This gives an azimuth plot of all received signals from GPS, Galileo and glonass. This may help to bebug why you are unable to get a position fix.

The phone is on the centre of dashboard, nothing blocking it.
I use to have iphone in same place and never had such of issus. This is samsung typical problem.

Try the app I suggest and see how many signals you get. Also what app are you using to navigate ? Google maps ? Waze ?

Are you driving in an urban canyon... I.e. a built up city... or open roads ?

[Revtnr]

Google maps and tomtom. It should be no different where I really drive,should work.

Ok pal no worries. Trying to be helpful but you obviously know better than me and my 20 years of working with navigation receivers in GPS, Galileo and Glonass.

For the record, it absolutely DOES make a difference what environment you are driving in, where your phone is located, and how much those essential satellite observations are being attenuated. Even the windscreen can reduce the signals, and the position on the dashboard and phone antenna can make a large difference.

If you are getting strong signals received with the phone, then clearly it is an 'assistance' problem with data, or the orbital data being saved to the phone.

Good luck finding a solution. I won't waste any more of my Sunday afternoon trying to be helpful. I am not paid to be here and advise... I am simply a user giving my own time for advice. 👍😉

Mines the same after the August update. I'm getting a near constant GPS signal lost error on Google maps. Waze seems to work fine. GPS status app is showing a big selection of sats.

I just restarted the phone and this helped. Not sure for how long. Will call samsung support later today.

I've tried that and it made no difference, I also submitted a report to Google maps.

For £1000 phone I expect absolutely everything working spot on and I don't care what make a difference to gps working correctly. You might be right but then this phone shouldn't cost that much as it's not fit for purpose.
