The lacklustre cameras and LTE band support are my main issues with those. You'll also want to reflash the phone when you get it - this may require asking Xiaomi for "permission" to unlock the phone (what happens when that server goes away?)

I agree the camera is not great. No Android so far was able to compare against my former S7 Edge (I guess S8/Plus and Note 8 are better though). And that's not okay. I have to admit though, the Mi 6 is a filler device for me until the iPhone X comes out.

The LTE band support problem is weird and I guess it comes from Xiaomi not pulling the right strings in the USA. We can only speculate though.

As far as I know Xiaomi still cant function on any US cell provider; dunno about europe but its not even an option for me

Yes, I realize that and it's a real shame. It seems Xiaomi can't pull certain strings -- it's hilarious that one has to pull strings to be able to sell phones in USA but hey. Your carriers are a pretty strong mafia. ;)

Jokes aside, again, it's a shame and you guys are missing out. Xiaomi makes the most no-bullshit phones on the planet right after the iPhones.

There are European versions of Xiaomi working on all European frequencies now in Poland. You can grab a nice Xiaomi phone for $150 with a fingerprint sensor and 3/32 memory.
