New issue 1464 by blyburn...@gmail.com: GPS Signal loss after most recent
release
http://code.google.com/p/mytracks/issues/detail?id=1464

What steps will reproduce the problem?
1. Since the most recent update, My Tracks loses GPS signal in areas where
it was not lost before. I have been a user for several years and track all
my bicycle rides. Since the last update, my rides do not track completely
and have gaps in them.

What is the expected output? What do you see instead?


What version of MyTracks are you using? On what version of Android? On what
phone?
V2.0.6
Driod Razr
Android 4.1.2

I see this too on my Nexus 4 with Android 4.4.2. GPS signal is routinely
being lost, leaving most my recent bike rides incomplete. This wasn't a
problem with earlier versions. Unsure if it's Android or KitKat related,
but something has changed and it isn't for the better.

On further review. If I run my tracks and map my ride at the same time, my
tracks performs better and records more completely. Still not as well as
map my ride alone. Any updates to this concern? Any suggestions? Thanks.

I always use My Tracks on my bike rides. During pauses the running time
continues but the real travel time was well kept. After several updates
that does not work properly anymore. Total time is ok, but real triptime
differs from actual triptime. What can I do to get back the correct real
triptime ??

If you continue to notice gps signal losses, please let us know the Google
Play services version on your phone.

I have this too. I go for 4 mile walks, and my speed graph shows a bunch
of erroneous sudden drops to zero speed, and then back up a while later.
Like notches in the graph. So it will, for example, show my total time as
one hour, but my moving time as only 40 minuets, even though I was moving
the entire time. Google Play Services version 4.4.52.

Same issue as #13. Google Play Services 4.4.52 (1174655-38), Xperia Z2 with
Android 4.4.2.

If I connect a Sony SmartBand I do not see this issue... only if My Tracks
is the only running app using fine grained location services.

Having the same issue as above on Galaxy Note 3. My Tracks seems to work
when starting a run, and the duration of workout is correct, but GPS signal
is lost repeatedly throughout exercise and when reviewing the route the map
shows me jumping around all over the place with as many gaps as there are
tracked areas.

recording, wondering if you can include an Android bug report. See

Seriously? You're joking right?
It's an app to track how you move during excercise, driving. Do you really
think it's a good idea for us to watch the phone during the entire time
just in case this happens?

Couldn't you make an app that detects sudden loss of GPS signal and
automatically create a report for later submittal?

One hypothesis is that when the Location mode is set to "High Accuracy", it
might report Wifi signals even when GPS signals are available. If you
frequently experience this on your phone, can you try setting the Location
mode to "Device only" to see if it helps.

I observed that the problem went away, i.e. I got a clean record of my
morning walk, after a re-boot a couple of days ago. Before the re-boot I
had had several other GPS related apps running. Could GPS apps be
interfering with each other by somehow corrupting the data provided from
the GPS module?

Comment #20 on issue 1464 by soundlin...@gmail.com: GPS Signal loss after

most recent release
http://code.google.com/p/mytracks/issues/detail?id=1464

Mine has gotten a lot better. I have erased everything (delete data), but
think that this is not the reason of improvement. I had set my Location
settings set manually to "high accuracy" (I'm translating from german), but
now that I check, they are at "Energy saving", which is strange (used
MyTracks the last time 3 days ago since it's raining non-stop).

It's important to point out that I'm using Tasker together with joaomgcd
<https://play.google.com/store/apps/developer?id=joaomgcd>'s AutoLocation,
which is tracking my position in parallel to act upon me entering
geofences. My goal is to have real-time email notifications to my home
server of enterings into geofences via tasker/autolocation while also
storing the entire track in high resolution via MyTracks, so that I can
export it upon arival and post process the kml/x and csv data.

In this context I'd like to comment that I'd love to be able to export kml
and csv data in one click, and then be able to use autoshare ny michale
haar
https://play.google.com/store/apps/details?id=com.dngames.autoshare&hl=en
in order to send both files attached to one email. The email step is not
that important since I'd prefer to be able to use Titanium Media Sync to
upload the two files automatically, but since it's now all that messed up,
I'm doing it manually via email, so that I can the post process them via a
python script.

I was looking at the source code at the repo last week in order to add the
stuff I need, but I then noticed that it has been pulled out of the open
source domain. That's quite a bummer, but well then... no comment.

Regarding the position accuracy, I believe that the theory of WLAN messing
up the GPS data is bogus, as Runtastic was getting 100% perfect location
info, always. In fact, when I was once using Runtastic, and MyTracks was
running in the backround and that Time I had the worst MyTracks recording
ever; I did this once to test. Of 12km about 2 got recorded, split up into
about 5 different (sub?)tracks, some really weired stuff, which really
pushed me to inspect the issue, as MyTracks used to be 1A last year.

I wanted to look at the source code because of that, to see what changed.

It's hard to tell, but I think that it's getting better, will be checking
it during the next couple of weeks.

I'd love to see an API letting me act automatically upon the STOP event in
order to export CSV and KML onto the sd card at once (CSV file doesn't
contain the summary which is included in the kml files and kml files don't
contain the ease of parsing, in order to analyze it further with google
maps).

It's also a pity that the calory counter doesn't get stored in the kml
summary. How about copying the kml summary into the csv file? I'd love that.

Same issue. Nexus 4. Android 4.4.4. Google Play Services 5.0.89
(1307510-036).

My Tracks has trouble acquiring GPS when other apps do not/show strong GPS.
Each time I open My Tracks to view status, it's attempting to acquire GPS.
I'm spending too much time thrusting the phone to the southern sky and
waiting. (Was once a terrific app. No longer.)

My Tracks gets its locations from the Google Play Services. So please make
sure you have the latest Google Play Services. In "High accuracy" mode, the
Google Play Services will return both gps and wifi locations. Wifi
locations tend to add lots of noise, so in My Tracks, we filtered out the
wifi locations, thus causing the gaps.

This problem should get improved in the latest version of Google Play
Services. A temporary workaround is using the "Device only" mode. We are
also looking for solutions to filter out wifi signals without causing
substantial gaps.

https://code.google.com/p/mytracks/issues/detail?id=1464

Today, I used My Tracks (hadn't used it for a while). It's now at v2.0.8.
It was absolutely HORRIBLE! Orange bar "Waiting for GPS services" every
time I took my phone out and unlocked it. BIG gaps in the data.

It USED to keep on ticking away, while I walked for HOURS on end (although
at times a little inaccurately while in my pocket - understandably). Now it
seems every time the screen turns off, it lost GPS location. The only way
to get it to get a location seemed to be to quickly turn GPS off and back
on again, but that would last only a short while. This was way out in the
country, far from any WiFi.

I try to conserve battery power. Have I done something to turn off GPS
while the screen is off?

I'm running a stock Android 4.4.2 on a Samsung Galaxy S4.

PLEASE, can I get back to what it was before?

@jshih - How do I determine if my "Google Play Services" is up to date?
I can not see anything like that at the Play Store, I can only check my
device:

If I open MAPS, (v9.1.2), and go to Settings/Google Location Settings, I
see "Google Play Services" there [When I tap on it, I see it's v6.5.87
(1599771-038), and it is enabled], and If I tap on "Mode", I see the 3
sources, mentioned in your post (GPS, WiFi Mobile networks), and I'm
currently using all 3 ("High Accuracy").

If I go to "Application Manager" and swipe right to "Running", I see Google
Play Services running (1 process and 1 service).

Is there anything else I can check?

never finds the signal other times it will take an hour or more. Also
sometimes it breaks GPS signal time to time.

Well, things are looking up. I went for a hike today, and it faithfully
tracked me for 90 minutes with the screen off, and in my pocket.
What I changed:
1) Turned off "Power saving"
2) Reset to "Recommended" all of the settings for how frequent/far track
points are recorded
3) Turned on cellular data.


More testing, with one of the above set at a time will be needed...

I am also experiencing this problem of "gaps" in the My Tracks recoding and
as also reported find My Tracks is very slow to capture the positioning
data from the GPS compared to other tracking applications. My Tracks used
to work flawlessly so something has changed in an update of My Tracks to
cause this problem.

Since May, 10th I am experiencing the same problem on my Samsung Galaxy S5
(then running stock 5.0). My Tracks 2.0.10 lost the GPS signal during a
workout and never recovered it even though the phone had a GPS fix in other
apps. I downgraded the phone to stock 4.4.2 afterwards and still
experienced the same problem with My Tracks 2.0.10. Then I downgraded to
2.0.9 and today I had the problem again.

I seem to be able to record full workouts if My Tracks never loses the GPS
fix but it seems that once it is lost it won't get recovered.

Hi #35. It is relates with the data services somehow. A while back my OPO
was having issues as well, playing INGRESS. It turns out it works perfectly
con 2g network, but as son as you get into 3g or LTE problem starts.
Instead of keeping a constant signal. It stays at one spot, then after a
while it jumps to the current position.

I had fixed the issue a few months back. By downloading a GPS.conf file
from WWW.derekgordon.com . But a few days ago I got an update from cm12.
And I'm lost again.

I'll post here what the GPS.conf looks like with this patch.

I'm guessing it has to do with the way 2g communicates with the gps modem.
Somehow on 3g it doesn't keep track as fast as on 2g.

From that config. I am guessing probably the accuracy threshold or
something.

I'm hoping someone could helps us here.

Someone just needs to get this done, and done correctly! It's amazing how
often this BASIC GPS ISSUE shows up!

If this was the case in my engineering team, there would be a HUGE meeting
to get this taken care of and to ensure GPS problems NEVER EVER come
back ...

Actually what solved this issue for me was that I removed Google Fit from
my device. It seems to somehow interfere with the ability of mytracks to
keep receiving a GPS signal. Additionally, my devices battery life has much
much improved since the removal of Google Fit.

Maybe there are other pieces of software like Google Fit that might
interfere with applications like MyTracks in the area of GPS usage. Google
Fit at its current status is a piece of crap in every way - I'm sorry I
have to put it like that.

This started to happen for me with the latest update (in July or so). I had
just returned from a trip abroad in which I had to swap my sim card so I
thought this was the issue. I'll try uninstalling Fit and report back.

Somewhere I picked up the tip that the problem with My Tracks can be
overcome by "tweaking" the recording settings. Since making the following
changes I have had no further problems.

Recording time interval is set to "Adapt for battery life" instead of the
recommended setting of smallest.

Recording distance interval is set to 20m instead of the recommended
setting of 10m.

Worth a try to see if these settings will also work for you.

Thanks @pwoodro... I'll give it a shot when I go for a run tonight!

PS: Obviously the other suggestions didn't work for me and for now I gave
up and used Runtastic Pro on my iPhone work phone.

Is any My Tracks developer looking into this yet?

Cheers,

I have seen the same problem with google play services version 7.8.99.
For me it was solved by turning off Wifi and disable "Scanning always
available" in advanced Wifi settings.
MyTracks seems to only accept locations from GPS, locations from other
sources are discarded.

Earlier suggestion didn't work, so I'll try hakangus' suggestion and post
my findings... Currently using Map My Run Anyway...

Thus far it is working (walked home while recording Track). No other app
was running though (usually have Play Music running at the same time to
listen to music). Let's try in hot when I jog tomorrow and see if is taken
care of as a workaround.

I do hope it is fixed someday so we don't have to tinker with the phone
settings themselves...
