For me is because of the protection of my privacy only a smartphone with open operating system in question, which is reasonably trustworthy. Thus divorce smartphones with Android and Windows, as well as BlackBerry and iPhone have made times. Then comes running out of what is reasonably user-friendly. All the better that there is a useful mobile with Firefox OS with the Alcatel OT Fire E. Yes, Firefox has not (yet) as many apps as Android & Co., but important is not how many apps are available, but what. Since Firefox OS covers the average needs from very good, a few people are likely to DB Navigator but already miss ... Also a pity that in the device only Firefox OS 1.3 installed. At least with my unit of d-living the update channel Deutsche Telekom is set that has actually announced about congstar to provide an update to Firefox OS 2.0. Then probably a reasonable QR-Scan or Eduroam support would be Firefox Hello, there. Even otherwise, a few minor oddities are perhaps resolved (eg: Why can not I write SMS only in portrait mode?) Hope dies last. Nevertheless: Who's private data (so why they are called so) reasonably protect, yet wants to have a user-friendly smartphone, comes to Firefox OS barely passing. As for the hardware: The part looks chic from, runs smoothly, making acceptable photos, the touch panel has convinced me and the battery life is OK. I am happy. Shortly a few facts that can help you classify what has been said: This is my first smartphone, I do not use it too often, the part now have a week so cant comment on durability.
