GPS Accuracy Issues

There are several ways in getting your device GPS accuracy.
1) Is to enter your home location in Google Maps.
2) Is to set up the device High accuracy settings under the location settings.
3) You can go into Google Maps and in the left upper corner three horizontal bars tap then set up timeline. Now from that point Google will keep high accuracy on your device because your device will be tracked to wherever you go with in GPS range.

Actually I was going to suggest the opposite: set it to "device only" and see whether it makes a difference.
"High accuracy" is misnamed: it isn't really more accurate, and can be less so. What it does do is give you a faster location, and a coarse location when there is no GPS signal, but in a location where there is a good GPS signal the additional accuracy from WiFi and cell towers is negligible. But if there is a problem with Google's cell or WiFi map the wireless information can mess the accuracy up, sometimes spectacularly.
So my first suggestion would be to try device only and see how it behaves, just in order to eliminate one of the variables. If the problem remains we will know for sure that it is with the GPS rather than the wireless location, and then you can see whether the high accuracy mode improves things. If not then we'll know it's actually the interaction with the wireless location that's degrading the accuracy.

I have tried both of these things already, and still the same result.
Hi, having read through your previous thread I notice you are using 'GPS Status and Toolbox'.
Might I suggest that you try 'GPS Test Plus'
https://play.google.com/store/apps/details?id=com.chartcross.gpstestplus
It gives a far clearer picture of the satellites within range and the respective signal strength of each one, and will display up to a total of 24 satellites.
The first screenshot is taken inside the house, standing next to a window and the second screenshot is taken when standing well away from any windows.
In my experience the signal to noise ratio (SNR) needs to be in the yellow or green areas for at least three satellites to get and maintain a reasonably accurate fix.
If I step outside, the number of satellites and strength of the signals increase significantly.
It could help to determine whether or not you have a problem with your GPS receiver.

I already tried that, and possibly, the receiver might be the problem. When I download assisted GPS data, it shows me moving at 6 mph when stationary.
