Thanks! The Mix 3 was unlocked over a year ago. I didn't really want to get a new phone, but I dropped it and it was run over by a car. The screen survived, but the back was broken along with the camera glass. I replaced both, but the camera no longer focuses properly, I think the problem is that the original glass is also part of the lens system and all the replacements are aftermarket rubbish that don't include the lensing. I don't use any third party cloud services, Xiaomi or otherwise, I'll be using Titanium to transfer the apps. My photos and documents are synched with Nextcloud on my Linux server, haven't investigated yet if I can somehow hack the apps to be synched there as well.
