I bought the first smartphone to use waze. I did that yesterday :-), but the GPS has stalled in the second. The hard part was figuring out how to activate it, curiously there is no GPS option in the quick menus, but a "location" option, and in this option, you must check the advanced localization for GPS is started. The "applications, inevitable on many smartphones, and impossible to remove are optional here, you are asked when you first start if you want them. I imagine therefore that it is possible to uninstall if you do not use it (but I have not checked). For now I have nothing but good with this smartphone. Even the battery pack to charge for the first time tonight, after 12 I still 75% battery.
