Yeah, i've installed the actually latest (v 4.30) firmware a few days ago. And in the changelog is written "increased sensitivity while moving at low speeds". I hope that will help a little bit, because with the former versions i had it was horrible. Even the daily distance the device shows me was horrible. The device told me i traveled like 27 km but i was sure the distance was only around 22 km.
An inspection of the gpx file lateron ont the pc showed me that i was true with the 22 km. Thats really annoying.

The only nice thing that i can use with the device is actually the maps itself. But everything made with the tripcomputer is nearly useless. I hope there will be some changes in the future.
