On my bike I’m using an older Moto G (3rd Gen) with Kurviger as my main navigation device (my formerly used Garmin Zumo 220 now only serves as “hardware backup”). The Moto G is a perfect solution for me, because it has a very moderate power consumption, is waterproof and not too big (5’’ display).
The Moto G runs with Android 6 and the Kurviger app works like charm with it.
I successfully tested the following devices and Android version (although not all of them really used during bike tours):
- Samsung Note 10.1 (Edition 2014) with Android 5 (“Lollipop”), 3GB RAM
- Moto G (3rd Gen) with Android 6 (“Marshmallow”), 2GB RAM
- ZTE Axon 7 with Android 7 (“Nougat”) and Android 8 (“Oreo”), 4GB RAM
- Huawei P20 Pro with Android 9 (“Pie”), 6GB RAM
So after all I can confirm that the Kurviger apps works with Android 5 - 9.
