"Aquaris X" with Android 7.1.1 works great.
In contrast, "Google Pixel C" with Android 8.1.0 (Kernel 3.18.0-ge2c279d, Build-Nr. OPM4.171019.016.C1) crashes when a location is typed. The outline map Europe is shown for about 20 seconds, then crashes. The default location "Holzacker" was never used.
Thanks for your effort.
