The Blackview BV5900 is an outdoor smartphone with a good protection class and a large battery. It doesn't even cost 200 Euros and could be a real bargain if you need a phone for harsh environments. We'll take a closer look at the smartphone in the review.

In general are good products but very bad after sales support, very bad patches update...
I bought BV7000pro and a BV9600pro, the latest update for the 9600 is one year old and there are many critical vulnerabilities unpatched. Of course there are also many bugs, for example most of the APPS are non started automatically and you are forced to start them manually every time you power on the phone... ???
