"Hi, I had good experience with the application over my Samsung S10+ and here is my question. Starting few days ago, the raw measurements are no longer logged although the switches are turned on. Is there any change in the system/ Android that caused that? Any idea why is that so?"
Version: v3.0.3.1

"Edit: version 3.0.6.1 fixes the problems I had, everything works great now. Thanks for the communication, devs! Original review below: Signal strength plot doesn`t seem to work at all. Yes, I`ve tried it outside. Status and Skyplot tabs show satellites, Map shows my location. The problem is with the Plots tab not displaying any graphs, only an empty white area, with the text ``No Measurement has been received yet. Please turn on Measurement and Location in Home tab.`` Yes, they are both enabled."

"Useful app for getting raw pseudo-range data out of the GNSS receiver. However, while this works fine in the gnss_log_*.txt file generated (which does contain many lines starting with “Raw,”), when I send the log via email, the also generated RINEX file gnss_log_*.21o sadly is nearly empty: it contains, apart from a 10-line header and once-per-second timestamp lines, only lines consisting of the 3-character satellite identifiers. No observation data or anything else. This is on a Google Pixel 3. This problem still exists in v3.0.0.10."

"Why is there no pseudorange measurement? I see accumulated delta range but that is not the same thing by my understanding. It would be really cool if you output the raw psuedorange so people could compute their own fixes."

"I like the amount of data you can capture and the RINEX format. I have a question. I am using an external GPS receiver and have mock locations enabled. How do I make sure the app is using the external receiver instead of the built in GPS?"

● View all location and raw measurement data.
● Control offline logging using `Start Log`, `Stop & Send` and `Timed Log`.
● Enable specific items to be logged using corresponding switches in Home Tab.
● Delete existing log files from disk.
MAP TAB:
● Visualize on GoogleMap, the location provided by GPS chipset, Network Location Provider (NLP), Fused Location Provider (FLP), and computed Weighted Least Square (WLS) position.
● Toggle between different map views and location types.
PLOTS TAB:
● Visualize CN0 (Signal Strength), PR (pseudorange) Residual and PRR (pseudorange rate) Residual vs time.
STATUS TAB:
● View detailed information of all visible GNSS (Global Navigation Satellite System) satellites such as GPS, Beidou (BDS), QZSS, GAL (Galileo), GLO (GLONASS) and IRNSS.
