Not sensitive enough satellites for my taste (and when one seeks his way ...) ** Update after one year of use: adapting the display brightness to the ambient lighting capricious - GPS answer live ... on arrival with Maps - background battery charge Wi-fi service - max 1 day - sensitivity the inadequate Wi-fi - internal speaker crachotte of Ascending - conversation becomes inaudible; I will also do with ACER.
