I am a french paraglider, I fly in South Burgundy and in the Alps. I used to fly with a copy of Vertica with version 4 and 5 since 2014. Last winter I had a cable connection issue with the "Vertica" so I switched to an old smartphone (Motorola E 1st Gen) with LK8000 Android 6.1r version.
At the beginning I was very excited to use this android version , it worked perfectly fine but one month later some glitches appeared on the track. Soon after, there weren't some glitches but the whole track was made of glitches.
I still don't understand why there are these problems. I suspected the vario and my phone (that are close to my Moto E) but sometimes in the same day for short flights there is no problem and for bigger flights the track is awfull (like this late saturday).
Is anyone has already encountered this kind of problem ?
