this device is full of defects which make it unusable
often has to be reset because impossible to switch on , also battery is holding less than 1/2h in many of items sold from (2 other costumers with the same problem than mine)
updating firmware solved wifi issue , but not this problem , which is hardware defect
and seller refusing to communicate (eletroworld ...), my item is new in its box and no possibility to send back without his agreement
just lost my $$
