I once had a low-end smartphone 40 which featured some very interesting features that this phone much more expensive does not (programming extinction and automatic activation of the phone and FM radio). Autonomy is also significantly worse (2 days against 4 previously) while the performance and fluidity are not exactly best. As against the quality of the display, visible even in bright sunlight and fluidity of the touch are perfect. The overall finish is excellent and the quality of reception (telephone, Wi-Fi, GPS and 4G is excellent). I would have liked a more compact phone but it is unfortunately much more ... The sound is also perfectible (the speaker placed on the back gives a rather average sound).
