Superb smartphone, very pleasant to use with the updated version of Android 5 (buying end of January 2015). It has exactly the right size to be comfortably used in mapping GPS with the appropriate software (Osmand in this case). The HD screen is of outstanding quality, at least as good as that of an i-phone or Galaxy S5. With the 32 MB, no noticeable lag even supposed loading several intensive applications. In heavy use (hiking with GPS chart plotter in operation all day, plus music), the battery lasts all day, that's all we ask. Of course, it is a true 4G compatible with European standards, so OK for any French operator. In short, a good choice I recommend.
