Hi! I'm about to start as an Uber driver but can't find any info about wheter it is necessary to have a compass on the phone, I've seen the requirements like: A-GPS and GLONASS... but nothing about compass... I'm asking because I bought a phone a couple of months ago and it doesn't have it and depending on the tips I will consider of changing it. So, in your experience is it really needed? Does it help when trying to find a way to the customer or in general city guidance? Also any tips are appreciated!
