Low Resolution in Front Camera Issue

So i think everyone of you have come across this annoyance that third party cameras on Redmi Note 5 Pro (Note 5 China) cannot use the full 20mp resolution in front camera. Only 5mp resolution is utilised.
So can anyone point out what exactly is the reason for that and is there any fix possible for the issue, as this is a major reason for me to not flash custom roms as even gcam doesn't use full resolution of front camera.
Replies appreciated.

I tried the Nokia camera port and it works. It Utilizes full 20 mp front sensor.

yeah i have tried nokia cam too, it utilities full 20mp front. But the quality is nowhere close to google camera and that's why i want the gcam to utilize full 20mp front.

Most images come out at 7.2mp

I have an unlocked S20 Ultra here in the US. For some reason most of my images come out at 400x1800 Does not matter if its f3.5 or f2.2 or f1.8 which I assume shows which camera it comes from. The 108mp works at 12000x9000 and pro comes out at 4000x3000. But if I try to zoom or wide it always comes out at 4000x1800. What am I doing wrong. Or is this a function of the software.
0.5x,1x,4x,5x,10x,30x, and 100x all come out at 7.2mp.
tired scene optimizer on and off
thanks

Try in 3:4 ratio.

I was using Full Mode before. I thought it meant it was using the full sensor. Guess that was wrong.
Now In 3.:4 mode I get only 12mp images. Not the 48mp that is supposed to be with the telephoto camera.
All files now depending on F1.8, f2.2 or f3.5 are 12mp.

I think that you can only get 12 mp from periscope camera because of pixel binning.There is no option for 48 to toggle as on main camera for 108mp.Maybe if someone know a way to switch to 48mp periscope write it down but i think that that is impossible.

Optical Zoom too?

Hi everyone
I'm thinking of buying this phone. But i'd like to know if it has Optical Zoom at all?
On the Mi.com page it only says 30x digital zoom. So i hope anybody can say/confirm it has at least a little bit of optical zoom.
Thanks in advance - have a nice weekend!

Should be at least a 2x optical zoom.

No, this phone doesn't have telephoto camera so there is no any optical zoom.

General S22 3x telephoto vs. Pixel 6 Pro 4x telephoto

What is going on with S22 telephoto.
I was expecting some difference between 3x and 4x, what I found was atrocious. S22 telephoto looked like it was not a telephoto camera at all, at least compared to P6P.
Is there some kind of a bug in S22 camera software?

Pixel 6 gives a great photo than the S22 because the google camera is the best!!!

Opinions, opinions..., I have S22 and am very impressed with this phone and its camera, went outside yesterday to check it out and I think this 'vanilla' is a hit. Had an embarrassing moment though, thinking that the camera was a dud when I unknowingly left 'portrait' button on and saw ghosts appearing in the viewfinder(Ai was attempting to create a blurr effect in the scene background) but it's all good now and the x3 zoom feature is perfect, some examples bellow.
I also have S22U if I'd feel the urge to "zoom it to the moon".

Tomorrow, I'll post comparison pix between S22 x3 and P6P x4 to illustrate my point.

I think I know what happened - when I was testing the telephoto camera in S22, it was getting dark. So S22 must have switched the camera to wide automatically, so the 3x zoom was entirely in software.
Beware of that.
Pixel 6 Pro did not have that issue, so the result of 4x was nice and crisp.
Here's a comparison in daylight.
P6P pictures were taken with wide and telephoto.
S22 pictures were taken with wide, telephoto, and telephoto at 0.75 x distance to emulate 4x of pixel.

Both camera samples look out of focus, idk why. Are the lenses clear?

What are you talking about?
These are tiny crops of much larger pictures to illustrate the point.
For example, the S22 wide shot is a crop of 190x130 pixels from the full shot of 4000x3000.

So why are you showing compressed/reduced photos asking for opinion?

I am demonstrating the quality of the telephoto camera in comparison with the wide camera, and also in comparison with the P6P.
If I posted full pictures, then you would have to do the crop and zoom by yourself to see the difference.
So I did the cropping and zooming myself, for your benefit.
Are you new at this?

The P6P has a real 4X zoom from the Periscope camera, the S22/S22+ doesn´t have it this system

The S22U Camera App (not the expert Raw) is horrible.
The images all look muddy, far too little details.
I hope they fix it.

Question What is the zoom lens for?

Hi all. I am debating the switch from the regular 6 to the pro.
Looks I will be getting bigger higher refresh screen (pro) which is curved (con) and with worse battery life.
One thing that is not clear to me - is the zoom lens used in any other situations than when actively selecting it? For example - which of the lenses is being used when you select the portrait mode in the camera app? Is it using the telephoto lens to battle the fish eye effect?

I have never gotten the telephoto lens to show up in gcam. Only the 50MP wide cam and the 12MP ultra wide cam. The 50 gives you zoom options but the 48MP telephoto never shows up

It's a 4x telephoto, which is a lot for portraits (so portraits are taken using main camera at 2x magnification).
No, it's not being used for enhancing ultrawide. I suppose it's also because if the same reason mentioned above (OnePlus uses it's 2x tele for this as well).
Telephoto is really only useful for zooming 4x and up all the way to 20x, when photos are still kinda useful (depending on a scenario), thanks to being a 50 MP sensor and some Google's AI magic.
I take a lot of zoomed pictures and I don't mind curved display. Battery is okay, 6 hours of SOT are real for me, usually on social networks and news scrolling. Sometimes I play a League of Legends, than it will drop to 4-5 hours.

Zoom lens is for... zooming in. I would think that would be self-explanatory?
It kicks in when the magnification reaches about 4.5x. Switching between sensors is exclusively a matter of changing the magnification level, not by "selecting" a particular camera. There are other details considered before switching sensors, such as exposure requirements.
You can tell which sensor is in use by briefly blocking sensors with your finger. When you see your finger on the screen, you found the sensor that is in use.

Yeah, thanks
What was not clear to me was if it is being used when shooting portrait photos, as some phones (e.g. Oneplus) do.
Looks like this is not the case.
I will stick with my vanilla 6 then, not missing out on much, subjectively.

Portrait photos can be made with ANY lens, depending on the distance and direction to the subject(s).

Is it so? How does the portrait UI looks on Pixel 6 Pro? On the vanilla pixel I have the options to shoot it in 1x and 2x only. Does the pro version offer a higher magnification, using the zoom lens instead of main one?

No. 1x and 2x are the only options available. The telephoto lens isn't used in portrait mode.
