gpstest VS personalDNSfilter

If you really want to see all the gps-like services out there and have android, you must play with the open-source GPStest

https://github.com/barbeau/gpstest

I've been fascinated for years how badly GPS does altitude (mean-sea-level)

in the USA they had to build an augmentation system for airplanes for altitude (WAAS)

Use https://github.com/barbeau/gpstest (Android only). It give the most real time data on GPS and accuracy.

GPSTest (version 3.10.0): An app for testing GPS and GNSS capabilities of a device

I'm the developer of the GPSTest app, and I built a crowd-sourced database of device GPS/GNSS capabilities.

It is possible on quite a few modern Android phones to access raw receiver data and do post-processing using a rinet file to get mm-level accuracy. It's a little over my head since this isn't my industry. One of Google's more obscure Android apps to be used with it: https://play.google.com/store/apps/details?id=com.google.and...

GPSTest also carries some logging functionality to do the same: https://github.com/barbeau/gpstest

If you did not install GApps try outdoor with an unobstructed view of the sky for 10 minutes to get the first fix with apps like GPSTest by barbeau or SatStat for example.

I hope more people can contribute with GPSTest app.

For a visual of what speed accuracy figures one might expect, I suggest trying GPSTest (not to be confused with similarly named apps). It'll display accuracy values along with many other values.

If you install this app, you'll see exactly what GPS data your phone is picking up.

I can see GPS, Galileo, Chinese, Russian, and Japanese ones.

Maybe try https://www.zenz-solutions.de/personaldnsfilter-wp/ https://github.com/IngoZenz/personaldnsfilter btw: its on FDroid Store too

I recommend personalDNSfilter (GitHub) as the on-device filter, which then gets passed through to nextDNS or any other DNS of your choosing. Been using it for over a year, it's superb, but I wish we had something as powerful as Portmaster (desktop-only for now, although the team has considered Android, and they thought it is a viable option)

personalDNSfilter (version 1.50.53.5): DNS request based Host Blocker over local VPN using a Blocklist

If you want DoT support then you can try personaldnsfilter

I've been looking into doing something similar and stumbled upon a method that uses personalDNSfilter with OpenVPN for personalDNSfilter, which is a special version of the OpenVPN for Android app.

You could try personalDNSfilter ... https://www.zenz-solutions.de/personaldnsfilter-wp/

Android Update: fix can be obtained (on a non-rooted phone) by using the Personal DNS Filter app (install from PlayStore). This app allows to manipulate DNS by creating a VPN.

Here's our GitHub page and here our website. Here you can see a video of personalDNSfilter in action.
