I bought a Samsung z2 at pep Thursday.the phone is really nice but I want to know why doesn’t its Bluetooth pair or searches other devices only Samsung is it like iPhone that only shares to iPhone? and the hotspot also doesn’t work on my Samsung z2 why not? and share it is very slow on this phone. I thought the z2 is android now I see its not.and if I go on whatsapp most of the times it says no internet connection and connecting I can’t send a message unless its connected WhatsApp looks the same as iPhone.any solutions about the hotspot and Bluetooth please?
