Hello
I have the same problem with NextGen Israel 9.18.27.687519 I am in Belgium I explain myself from Antwerp to Brussels E19 double tunnel has 4 bands of 1650 M it works but back Brussels to Antwerp always crash at the entrance of the tunnel of 1650 M so I put all the schemes by default and day and night manually on my Samsung s7 mobile phone and tablet Samsung 280T all to work in the tunnel with the skin 11/7/2018 GSM Samsung s7 and the skin 27 / 11/2018 tablet Samsung 280T with NextGen Israel 9.18.27.687519 I will test another scheme that suits me and put back in automatic mode day and night
For it to work I deleted the UX folder and the DATA install in NextGen Israel 9.18.27.687519 put the UX and DATA origins without skin that I could find on another site and added the UX update 2018 11 27 and delete the Save folder
