Few months back I have purchased blackberryz10. after using it
I realise that was my biggest mistake to buy that product.
because blackberryz10 is running on
OS that has very limited numbers of apps and secondary
it’s semi android that means only limited numbers of apps can support
and while using it’s heat up very easily!
and sound quality is just fine
nor too gud nor too bad
and it’s not at all easy to use.its kinda tricky
