[Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans] mathey:
Did someone figured out how to deal with VR on that phone?

I'm generally not using the VR for gaming, but for playing 180/360 degree videos (usually in SBS format). For few years I was using the ZTE Nubia Z7 Max with VR Box 2.0 goggles and AAA VR Cinema app for that with just the perfect result. The effect was always stunning, everything looks pretty close to the real with a nice 3D effect of the items (in some apps the image looks more flat, where that effect is not visible, but with that app mentioned above the result was very nice), especially if the video file resolution is good enough. Unfortunately, the Nubia had problem with playing videos in vr in 4k resolution and higher. Doing some experiments I've figured out, that the resolution 3684x1842 (which I'm calling 3,7K ;) ) in H264 is max to provide a stable playback in 60 fps. The Nubia unfortunately has too weak components for something more. But anyway, the image quality is very good in that configuration.

Moving on to the POCO F2 Pro, I've decided for phone upgrade in recent days and was hoping for an absolutely stunning effect with the Super AMOLED screen. Unfortunately, the result is a nightmare as for now. The POCO fits quite well in the VR Box 2.0 Goggles, but that's the only one good aspect. Unfortunately, on the MIUI12 the AAA VR Cinema app have a problem with opening in the not-fullscreen mode. It could work only in a fullscreen mode, but everything is then stretched and the big part of the image is cut out! It's impossible to adjust the goggles with that image - you could only get a squint from that. I've tried a big bunch of the free apps for VR available on the play store and most of them simply doesn't work on POCO (can't read files, generate improper image for which is impossible to adjust the goggles or are simply a joke). The most promising is VRTV Free, but it's quite hard to adjust it, and the 3D effect is not quite visible as was in the AAA VR Cinema app on Nubia - everything looks more flat than 3D. I was also hoping for a stunning image quality on the Super AMOLED screen and you know what? On POCO, when you put out it into VR goggles there are noticeable, quite visible black gaps (a black holes, hehe) between the pixels, so in my opinion the image quality is a wayy much better on the Nubia despite its the IPS! Probably on the Nubia Z7 (NX506J), which had the 1440x2560 screen resolution it would be even better. About the POCO, I'm disappointed about the image quality of that Super AMOLED in VR. In normal it looks better on POCO than in the Nubia, but in the VR for me the Nubia clearly wins - it only has a little too weak CPU&GPU.

So what to do about that now? The VR is very important for me. Do you know the apps (could be the paid) for VR which are working good in POCO? And the same for the Googles? Cuz maybe the VR Box 2.0 Goggles are the problem too, because despite the fact that the POCO fits for them well physically, they are designed for phones from 3,5"-6" according to the specs.

EDIT:

Yeah, it looks like I've figured out some solution! Don't know why I haven't thought about that before, but I just came up with the idea of trying some earlier versions of the AAA VR Cinema. And yeah, on the 1.5.3 version I'm able to start the app in a non-fullscreen mode :) Buttons & etc. aren't stretched and the whole image fits the screen. And the image quality in the VR Box 2.0 (exactly it's an Esperanza model) is very nice! Maybe even better than on Nubia, because now the gaps between the pixels are hardly visible and are comparable to that on Nubia. But the performance gain is flawless and now I finally can play HEVC videos (had to use AVC before on Nubia). For me the AAA VR Cinema app is the best one out of the free apps (haven't tested the paid solutions - does someone know any worth trying?) - it has that stunning 3D effect due of what everything looks pretty realistic, which any other app doesn't have. That version of the app also in the fullscreen mode have the proper screen size, so it's not cut off and perfectly fits the screen, but in the fullscreen I have problems with adjusting the googles (maybe here other goggles will help). As for now I'm satisfied of using that setup on a non-fullscreen mode. And there's an additional problem on the POCO - the image is shifted to the one side of the screen:

so you can't properly place the phone inside the VR Box 2.0 goggles with the center line matching the notch, because there are not enough space in the tray to move the phone to the side. It's causing that the view is shifted a little and you can feel like you're not exactly in the center of the action. But the image is looking properly anyway. I've found that its caused by the system navigation buttons (because of some space reserved for them at the side of the screen). After changing the steering in the system options from buttons to the fullscreen gestures everything is allright!

There is also the option to cut a little piece of the plastic of the tray on the side, so the phone could be moved a lil more to the side. Or use other googles. In the meantime I've tested the googles from shinecon (the Box 5 mini model) which doesn't have that problem because they don't have the tray and they have the optics more comfortable to setup (but also not fully independent), end the lenses are probably better than on VR Box 2.0 so the image is more bright (at that's maybe to the plastic color which is white here?), but personally I prefer the lenses from the VR Box 2.0. They have a little blurry image (just a little) so the pixels shape isn't that noticeable. On shinecon I think everything is more sharp. I would say it's like a kind of antialiasing in the VR Box 2.0 :D So I prefer them, because they also are av little bigger, have the skin-like binding around the contract area (on shinecon it's just a sponge...) And the tray is much more easier to use. But they have worse ventilation s due to that, on the Nubia I've sometimes was thinking that the phone will explode due to the heat. But the POCO isn't overheating so it's not a problem.

But there one more little problem I've noticed on POCO - even on the latest version of the app - it has the tendency to crash the app on start after one use, do you can't stay it. The solution for that is to go into the information about the app and enable and right after disable the fullscreen mode for it, and when you start the app hold the phone vertically, not horizontally, after the successful start you can change to the landscape. So there are a little problems but finally everything is able to figure out, with some additional "ritual" to do but it works. I hope that maybe that informations would be helpful for someone ;)

I will also willingly test any other solutions, if someone would come with them. Also it would be nice to know your propositions about the apps to use (free or paid), but as for now the AAA VR Cinema is for me just the best and probably only one which could generate the proper, stunning like realistic image (the effect is like on the YouTube or even better). It has some disadvantages (like no timeline of the video so you can forward or rewind with some limitations, and the control buttons aren't hiding but can only be always visible or always off, but that are the things capable to living with them, and for the image quality I could forgive that.
