Tracks data & ruler problem on android 4.2 [solved]

I encounter a strange behavior of OruxMaps since I updated my phone (Samsung Galaxy S2) to Android 4.2.1 using CyanogenMod 10.1. The problem is described below:
As you can see on this screenshot, I'm supposed to have traveled 71km in 38min with an average speed of 120 km/h although in reality I traveled 2.7km at an average speed of 4.4 km/h. The same speed problem can also be seen on the graph. In contrast, the maximum speed is correct and if I export the track in gpx format, all the information it contains (including the distance and speed) is also correct.

Is the problem coming from a bad setting in OruxMaps? A problem in Android 4.2? In CM10.1? In my phone?
What can I doto fix it?

me too with CM10.1 and galaxy nexus.

And I find a strange behavior when I use ruler. If I move some mm the km change very much!

I have noticed the same bahavior.
I tried changing the unit settings but nothing has changed.

Hi, thanks;

Which kind of map are you using (online, offline, datum/projection,...)?

orux

I use OSM cyclemap online and offline downloaded with oruxmaps and rmap created with compegpsland. I used this map witn 4.6.2 without problem.Would you like I install old version for understand if the problem is orux 5 or android 4.2?

Hi,
I tried with both online and offline maps. I'm currently using the NTF (Paris): Centre France datum but I also tried with the WGS84 : global definition datum.

By the way the NTF (Paris): Centre France isn't anymore the legal datum in France. It has been replaced by the RGF93 datum completed by the Lambert 93 projection (for more information, follow this link, sorry it's only in french). I May help you integrating this datum in OruxMaps if you want, just tell me the data you need.

Problem SOLVED!!!!

The problem was CM10.1, with the last update it's ok.

@WSEB: You too?

Thanks Orux!

Yes, this problem was specific to CM 10.1 and was solved by this patch http://review.cyanogenmod.org/#/c/29732/
