I have X70 Pro+, great phone, but came with Chinese Origin OS, in spite of comments suggesting otherwise. So far there is no path back, and, no path forward, kind of frustrating, the phone works ok, however, odd things happen, while all messages are received, no notifications are ever given. Android updates are not possible, Bluetooth remains a mystery. Once you get it to connect, all good, but starting up a new connection, is a challenge, it doesn't present a list of available connections in text, just a list of ?hex codes? is that what they are? You need to figure out which one you want. I have abandoned the phone and moved on, way too difficult to live with. it is Chinese only, closed and locked system. It is possible to ease the pain by going to Mode Cube and selecting Android option, but, its not enough. It works great as a camera, also works in part, as a second phone, that' s it, game over. So, no more Vivo, no more Chinese phones. Way too much time invested in trying to make it work, even in part. What a shame, you are left to wonder why, a corporation would spend so much time creating such a great phone and OS, that then fails completely on simple operational details.
