It is Mido.
As for your warranty, ask your supplier.

My supplier is my polish operator - PLAY. It's my first Xiaomi device. In LG i would relock bootloader and was okay, in Samsung I just had to keep 0x0 KNOX flag or somehow back to 0x0. Could you tell me how about Xiaomi devices? Does they have some security like KNOX, or they're just looking if bootloader is unlocked, or?

I read somewhere that you only need to flash stock rom(global)
Also i think you need to re-lock bootloader

Knox feature is exclusively on SAMSUNG devices.
On Xiaomi, locking bootloader serve as their system protection against people who will try to modify your phone while locked.
Unlocking bootloader WILL NOT void your warranty but in equivalent, its unsecured.
Rooting WILL NOT void warranty also.
But Fashing custom roms? well , officially, it will void the warranty but in some cases, they just letting it past.
In case you wanna use the phone to warranty,
I suggest reverting back from any modification like custom rom (if any), to official MIUI and stock recovery. (im not saying that it will recover warranty, u know just for hiding some changes done)
Another thing, read some warranty notes from your reseller if any.

I know only Samsungs have KNOX, just was asking if Xiaomi has it's own kind of security like KNOX.
Unlocking bootloader and rooting will not break warranty? Oh, it's impossible! Or i've read bad? Is really Xiaomi so cool, that they let owners customize their phones?
By the way - is flashin custom roms worth that on this device? Maybe better battery, performance, security, new features? (i'm not asking about customization like for example Lineage OS provides).

Knox is for only Sammy's phones nothin else.
Dont worry, it will not break warranty after rooting/unlocking bootloader.
About custom rom. For me its a worth. Its subjective btw.
What's worth exactly? Latest security update, oms support, fluid and responsive UI, better notifications handling, added some tweaks and latest features that baked into AOSP, and so forth.
also the upcoming Oreo support on mido too
All of which except the camera, audio, Video call support and some little bugs.
For battery life, mostly 9+ but its depends on different circumstances.

Thank You so much for replying. Maybe I will install one, which rom would You recommend?
And what about 4K pictures, slow motion video on stock? Where can I find photo resolution ? Why on slow motion mode videos look so horrible, like they were captured with nokia 3310?

I'll let that decision and exploring to you.
Ive used LineageOS, AOSPEX, ViperOS, RR and Slim. With each diff. level customizations and etc.
All are pretty stable and some others too. Pls look and check their threads.
Im currently on ViperOS.
About your other questions: one thing i'd say,
Camera isn't outstanding on mido.

Don't worry about warranty, you can always go back to stock and even relock bootloader if you want so there is no trace that it was ever modified.
PS.
Nie wiem gdzie kupiłeś telefon ale polski dystrybutor ABC Data zajął stanowisko że odblokowywanie bootloadera nie narusza gwarancji.

Yeah, this camera is.... crap, comparing to my RIP LG V10. But battery is freaking good, 2 hours screen on time and it took only 10%, it's amazing.
Thank you once again. As a fan of modifications, propably I will flash and test these roms. BTW - as I see LineageOS Oreo is already up for our devices.

If you want to upgrade your Rom look on the Xiaomi Site for Customers and Users. There you can Download Roms for your Phone Modell without the Problem of loose Guarantee.

You can unlock, root without voiding warranty. Only if you are giving for repair at service centers etc, download fastboot rom, extract and you will find "flashall and relock.bat" something name.. Run the bat and it will relock. Or you can simply use mi flash tool

You can still visit service center with custom Rom installed.
