Re: GPS?
Agree with you. I use GPS navigation when I am in Indonesia, I usually use Waze and Here Maps.
When you loose GPS fix whilst driving in a foreign country, you are in trouble. I know for the fact that my Wileyfox Swift GPS is bad for locating GPS and for accuracy of location. My wife's Blackberry Dtek60 is superb for GPS navigation compared to Wileyfox. Of course the latter is a much cheaper phone, but if you often use GPS for navigation , you have to consider this when buying a new phone.
Unfortunately most reviewers do not test the GPS and Radio Signal reception except notebookcheck.com
