Thank you very much for tip,i knew already that guide.the point is company highly advertised WATERPROOF on that model bv5000.And i did not get shower or bath instead of small drops of water..Phone is new,like a week ago arrived over here at post office.there is video like guy put that model into color box of painting,and than wash it under running tap water and working so....Comon man-couple drops of water from cup....Really ??? And what about warranty???The smart phone should be WATERPROOF how it say self company Blackview...Unfortunetly-TCP-is out of work complitely.i mean telefon work,just touch scren+bottoms are out of job-no react (home,back and adwanced )nothing happened if touch one of these and screen included
