I somehow feel they killed their own flagship with this phone

And this version of MIUI looks much better than the default ones on their Mi phones

Like I said, normal folk never really use it anyway lol, so it probably won't matter. 845/8GB does though.

I personally need NFC though to check the balance on my Icoca/Suica cards (amongst many other things), but I'm not looking for a new phone anytime soon myself lol. Just sticking around to see the ongoing results of Xiaomi's interesting little (which is actually what Poco means in Spanish) experiment here.

That said that launcher is pretty dope though. Categorising apps by colour? That's some crazy shit right there Xiaomi and I like it.

sry to burst your bubble.

phone so expensive, but no NFC.

GSMArena full review up. Nope, no OIS. Just EIS (and yes I trust these guys). Also apparently the frame is supposedly metal painted plastic, and headphone output isn't quite up to par... and no NFC (which nobody here probably uses anyway).

Otherwise, they liked it enough to nearly max out the stars they gave it. Hell, who wouldn't love a $300 845 phone, value proposition is just ludicrous.

Unlocking bootloader does not void the warranty provided you use the official tools or authorized method to unlock it. However rooting and running any form of unassigned code like custom third-party ROM then yes, the service center would reserve the full rights to reject servicing your device if you send it to them in such a condition.

That would not be a problem. 

As long as you can show proof it isn't your own third-party modification that damage the device any service center will accept it and your warranty remains intact. Obviously you would not send your phone in a state where it runs some third-party custom ROM would you? Because this will deviate from how the technician would diagnose your device when you send in for servicing.

Anyone can easily inspect if the phone is rooted or not. Not to mention lots of payment, financial and banking apps will refuse to run if the phone is detected by the said app to be rooted.

For the most part SC can service a bricked phone but on a case by case basis, I really would not risk doing anyform of firmware downgrading in any devices unless there is a means to do so from the said manufacturer. My suggestion, if you want a Android phone that you can mod and customize thoroughly then get a OnePlus instead, they even encourage users to try out tons of custom ROMs on their device and even post frequent updates on various stable and beta/nightly builds for users to try out. The Pocophone isn't exactly a developer's friendly phone on the Android market.
If the results vary by phone to phone running the same software and OS version then defiantly something is wrong with the camera sensor, probably the RGB sensor is screwed which would mean a hardware issue. Else this would be a software issue. Have you tried downloading and using something like GCam instead?
You need a QC 4.0 certified charger and a cable that can accommodate supplying that additional current. As of right now a QC 4.0 charger is next to impossible to find and I bet it's going to be bloody costly. Might as well get a charger with a Type-C port instead.

Running PE atm, so far so good
