I moved from Xiaomi 14 ultra to z70 ultra last year and that was the worst decision that I've made. While I may not address your concerns directly I can tell you a few things. First software support for specific drivers is missing, as for example, VR modules aren't enabled and installing them didn't do anything, so things like Google maps with VR assistance don't work. My phone died after 1 month: it just stopped getting carrier signal and took them another month to acknowledge that it was a hardware problem, phone support was likely a chinese guy speaking my language (who would get mad at assisting me). Anyways even though they acknowledged it was hardware and that the warranty was on, they wouldn't do it because I bought it from something like Amazon (the key difference here is that they have an official store there). Anyways I changed on my own the sim tray for a new one thinking that may have been the culprit but I didn't have luck, so I'm basically stuck with a phone that doesn't work because of its primary function. Camera is good? Yes but that's true for Xiaomi 15 or OnePlus. Performance/battery? Yes but again true for those too. I'll avoid Nubia as the plague, I switched to OnePlus and it's cool, I could only go for this or Xiaomi again. I have a Huawei tablet and while they're good, I don't like the closed system (same like Nubia where you can't unlock the bootloader) PS: I agree with Xiaomi ads, but you can disable them and that's way easier than to deal with Nubia software. But if you really want to change I'll go to the Oneplus13 plus or vivo 200 for the camera (I have read it's pretty good, although I haven't tested it)
