Poor GPS Reception

My dad's SGT 3 7.0 WiFi version has really bad GPS Reception, I've installed Sygic and selected the connect only to GPS Satellites Option in the Location Settings Menu. Sometimes it gets a GPS lock in a few minutes other times it doesn't connect at all. Does anybody know what the problem is?

GPS Location Doesnt work...

Hi I recently bought an m8 on ebay. I noticed that the gps doesnt lock on even though the location settings are set to high accuracy. As of now there is no service on the phone. When i connect to wifi it gets my location through A-GPS but without wifi it doesnt track my location even with offline maps. I tried calibrating my compass using the 'GPS Status' app, but it doesnt seem to work. Does anyone know if this is a software problem or hardware? can i replace the gps in the phone?
Thanks in advance for your help.

On the GPS Status app, do you see satellites being locked on? On the circular display, you should see dots, and bar graph below will show signal strength. You can typically lock onto several satellites very quickly, unless there is a hardware issue or in a poor location (sky is blocked).

no GPS signal | HTC 10

Hello guys,
I'm having an issue with my HTC 10.
My bootloader is unlocked and I have TWRP and LineageOS installed.
My problem is that I dont receive GPS Signal consistently. Sometimes, when I was connected to WiFi and running "High accuracy" mode and then went offline, only having GPS and cellular networks enabled (I don't have mobile internet) in the Location settings I sometimes have consistent GPS signal and lock.
But most of the times when I tun on my location service I don't get a GPS lock at all.
So I installed the GPS Test tool and checked my connection. Strangely, the app detects around 25 stellites but doesn't receive any data from any one of them.
It seems to me, that my GPS antenna is broken, or is it a software problem?
Thank you for your support!

Problems with GPS signal loss

Good afternoon.
Guys, I've been very angry with Google Maps.
When using turn-by-turn navigation, inside the urban perimeter works fine, but when I move to the rural area I have constant problems of "GPS signal loss".
I noticed that by losing the data signal (4G / 3G), Maps stops navigating. Do you have any way around it? Having a GPS dependent data signal is very infeasible.
Thank you.

Have you tried putting the location mode to "High Precision" or "Device only" in the location settings pane? Sounds like you're not using GPS, but cellular location....

I have already tried both modes and in both the problem is the same.
This problem comes from the time I had a Nexus 5, at the time thought was problem in his hardware, but start to be a bug of the Android itself.

Did you install the app GPS status? If not, please do. It will show an overview of your GPS receiving, and download the latest A-GPS library's.
However put the setting of location on Device only. That's important, it will use the internal receiver instead of network masts.

GPS Issues while non LTE band

Hello I have several issues with GPS when my A2 Lite is on 3G or 2G signals, so the GPS keeps dropping every few seconds but when the 4G signal kicks in, then I have continuous GPS signal with no interruptions until 3G or 2G kicks in again... If I set the phone on Airplane mode, the GPS also works just fine. The curious thing is that I previously had a REDMI 4 (Prada) with Android 6 which had the exact same issue and I thought it was a hardware issue but now with the A2 Lite the issue is the same... I replaced the SIM card just in case with no success at all. I find quite interesting that I have not found this issue in forums all over the internet and I can´t find people talking about GPS on the A2 lite at all, is like nobody uses google maps or Waze on their phones......
So my question is: Is this GPS issue a hardware problem or an OS issue.

Hi, sorry mate for not posting any solution, but assuring you''re not alone in this.
I have similar issue on my A2 lite. When I'm on Gps navigating to somewhere and a call comes in. That disconnects my GPS immediately. My phone signal would jump from 4G to 3G. My waze would state, "searching for Network". Which leaves waze stuck without moving.
I'm no technie, but I believe this phone has issues with the band support. When a call comes in, it jumps from 4G to 3G and we Can't surf internet. Not slow, but the internet just doesn't load at all. This jump somehow disconnects GPS. Intermittently the GPS would start working while on the call, but it's hard to say.

Gps and network are 2 separate things, what you guys describe is not gps dropping but the inability of the device to download maps data. That's the problem with maps apps which don't rely on local maps (downloaded in advance) but on updating the map as you go. The gps itself works really well on this device, it finds a fix in a few seconds within 3 meters. There's Here We Go map which can also use local maps and if you don't need up-to-date traffic info you don't really need internet. There's also an open-source map called PocketMaps which does the same thing and it's a solid app. If you need to test gps there's an app called SatStat which shows the exact number of satellites in use.

Hi,
Me and my wife have the same problem. Me with a Mi Mix 3 and she with a Mi 8 Lite. It's not an online map problem because the map is downloaded and displayed.
Moreover, this problem does not exist on our previous phone (OnePlus 5 and OnePlus 6).

I'm not an expert on this but the app SatStat is really helpful in troubleshooting location issues. In the main interface you can see how fast your phone finds satellites, how fast it can use them and how many. There is also a map interface which shows location based on network (cell towers and WiFi access points) which is generally less precise but faster. I'd suggest also testing the issue with Here maps in offline setting where it only relies on gps and local map.
