1. Phone calls (loads of conference calls, for which I use a wired headset with a microphone)
2. SMS Messaging (unlimited on my plan)
3. Navigation (very important, and is probably the most-used app on my phone)
4. Occasional internet browsing
All of this could be done by the Nokia E71, when Nokia Maps was a thing. If I want to move away from Apple, Google and the like, do I have any options now? Are there any trustable (and by trustable, I mean avoiding unknown Chinese manufacturers) phones in the market today that could do all four and (ideally) have better battery life than one day?
