Checking camera sensor - General Questions and Answers

Hello,
I was disappointed by the photo quality of my phone, tried different camera apps without success. Then I tried checking the camera sensor. I used app "Device info HW" and it says that camera sensor is imx258, not imx230, which was advertised (13 mp instead of 21 mp). It says that hardware is 13 mp and software is 21 mp. Then I took raw photo from engineer mode and it is 13 mp (image name: Capture20171224-152301ISOAutopure_4208x3120_10_3.raw). However it says that imx258 resolution is 4224 x 3136 (wikipedia) and only sony sensor i could find in this link with 4208x3120 resolution is an old IMX091PQ.
Does this mean than the sensor is wrong? As I understand the sensor is clearly not 21 mp and photos are upscaled to 21 mp? What guarantee do I have that it is a Sony sensor at all? I have an old zenfone 2 phone and photos are better. Is there any other way to check the sensor?

Camera Zoom Issue

Hello guys I have an issue related to camera can you guys please check if this is an issue or that's how it should work.
When you open camera on photo mode there are 3 modes to take a photo i.e primary camera, wide angle and telephoto for zoom.
Wide angle works fine and so does Primary camera.
Now if you put a finger on telephoto lense that is the lense next to led flash and switch to 3x zoom, it should use the telephoto lense but it uses Primary camera instead.
For a fraction of sec it tries to go to telephoto lense and switches to primary lense
However for portrait mode it uses telephoto without fail.
Don't put finger on the telephoto lense, switch to zoom, boom it works.
Now put finger on it. Hey, the camera app says, it's too dark you use the telephoto sensor, let's switch to normal one.
So: it works as expected. Not enough light = no telephoto sensor.

Cool, if that's the case it's smart af.
But that still doesn't justify 3x zoom with primary lense, is that digital crop in low light after all?

Nokia 6.2 Pro Mode Camera issue

Nokia 6.2 - TA 1198
Camera
96.9.0380.01
Issues:
- Pro Mode not focusing when not set in Auto which doesn't make the image sharp. Too much grain on pictures. This is very bad for night shooting. (Night mode is not that good for shooting low light and cannot make the image sharp than Pro Mode)
- Front Camera doesn't focus which is important on selfies. (Unlike Nokia 6/TA-1021 model) Blur is very visible when taking selfie near the Camera.
Please enlighten me that this is just a bug on it's camera.
Everything is working fine on camera except Pro Mode.

How only use the top lens (80mm telephoto) instead of a x3 crop from the 27mm lens

I would like tout take selfies but the caméra swish tout the 27mm sensor ans make a sensor zoom. How can i only use the top caméra lens (80mm) ?
I don't understand why you are trying to take selfies with the bank zoom camera, but open camera can do this, but I will say even at full arm length the zoom sensor will not be able to focus to you, this is probably with it's switching to the 27mm, so yeah with open camera when you switch camera it cycles all the sensors, but this sensor does not focus up close

Can you zoom during video recording?

I'm gonna purchase this phone but need to know if you can zoom during video recording?
At basic 4K30 setting does it switch cameras/lenses when you use the zoom slider?
Short answer is: nope.
At 4K30, with the standard camera app, you can select one of three lenses: ultra wide (0.5x), standard (1x) or the zoom lens (5x). With each your then have the option to digitally zoom in during filming, with the ultra wide then ranging from 0.5 to 2x, with the standard going from 1x to 6x and with the zoom lens you start at 5x and can zoom in to 15x zoom max. A slider will be on screen to help you with that. It's all digital zoom, so don't expect picture quality to remain the same.

This is bummer... Is it down to Xiaomi or it's the first phone with multiple cameras that can't switch on the fly during video recording ?!
OK that person is wrong. I zoom while recording all the time... I usually either use 720p to minimize file size or 4k60 for max quality. Maybe he's using the wrong mode.
My personal experience is exactly what Appelsap described. No way for me to switch cameras on the fly while recording video.
What about other apps like FIlmic PRO - do you have access to the other cameras?
In Filmic Pro I could only find the switch from back to front. Is there another way to access the other cameras?
So you can zoom, but only digitally using the same lens. You can't switch lenses to zoom even more during filming. I tested the 4K30 as was asked, didn't try other formats (720p/HD/8K) but expect the same result even then. Main issue would be that switching lenses would be noticable in the resulting film. The lenses are in a slightly different position on the phone - they have to be next to each other rather than on top of each other , so whilst zooming in or out you'd see the camera shift suddenly to a slightly different position. I doubt other multi-lens phones can switch camera's during filming, you'd notice it then too - but do correct me when I'm wrong and tell me how the software then solves the suddenly shifted perspective (or not).
Every other multicamera phone (as far as I know) is using different cameras (lenses) while video recording. My most current phone is Find X2 Pro and it is using all of the cameras, however they are not enabled in Filmic Pro, in comparison OnePlus 8 PRO is enabled and all cameras can be used in Filmic Pro but this is different topic.
So basically this is first high end camera centric phone that is unusable in video recording, what a shame... I will cancel my purchase then.....
My Find X2 Pro is the best package overall but I'm missing the 2x telephoto camera as there is quite a gap between the 25mm main camera and 130mm 5x periscope one.

It's not only the perspective. Different cameras have different aperture, meaning different exposure. So if you pay attention, you will notice that - it gets darker when the phone switches to 5x camera. Don't know what cameras and aperture have the other phones but I'm extremely interested in an example video zooming from UW all the way to periscope and producing usable picture quality in 4k.
Just wanted to let you know that on latest EU weekly, the switches cameras on fly during video recording 1800p.
I also confirm that the video produced is not the best quality as expected - changing the camera changes the exposure and focus too.
For 4k it doesn't switch cameras.

Just tried it, and you are so right. At 1080p it does switch lenses during zooming (in/out), which is very noticable in the result, so why you'd want that is beyond me really. But it is possible. I'd like to see another phone do this without changes to exposure and focus, that seems very unlikely to me.

camera only shows 5.2 MP

After one ui 2.5 front camera shows only 5.2 MP.
Its that normal thing
Use the second front button for a wider selfie. It will switch to 8MP.
