lost gps afer 40km speed

[xSENSORx]

Hello,
I´m using Locus Clasics on Samsung Note 8 paired with Locus Tizen compation. On bigger MTB rides it starts losing GPS after about 40km. Then it is complete mess, only rarely records GPS location.
Have anybody met such a behaviour?

You can activate the NMEA recording in Locus and look what location information is arriving from Android.
