I'm experiencing problem with my Xiaomi MI4 front camera. Everytime I capture a video from front camera, the resulting video is flipped horizontally. But capturing images from front camera just works fine, though rarely it flips image too, that happens cause of the angle we hold the camera to take the picture. And that can be fixed with apps like Pixlr. But the video...it really sucks. It gets flipped every f**king time, doesn't matter what the capturing angle has been. Please someone help fixing this bug!!!
Thanks in advance. ?
I have this amazing device since last month and as I travel a lot I'm facing a strange issue with the selfie camera. When you take a photo with the front camera you can't select the zone to focus and so in places with a lot of light my photos resulted to be too overexposed with the background that was really difficult to see. Is there any solution with the stock camera app?

the fron cam has fixed focus so you can't change it manually. Try moving your hand and re positioning the camera. That generally helps me in fixing the exposure to light.
I came upon this very irritating camera bug. Can you guys check if you have same problem?
I have a Chinese model (PDEM30-11-A.13), with software 7.1
When pressing the 10x and focus on an object approx 10m away, you get a crystal clear image. When you then move the camera over to an object approx 2m away, you also get a crystal clear image for a second or 3. After that, the camera seems to switch to another lens, and the picture become real ugly. Only way to get crystal clear image again is by focusing again on something rather far away...
if you want to stop switching lens, go to pro mode and choose the lens you want
Hi!
This may seem like a strange question. What does the camera on the back of the Mi 10 Ultra that looks like the periscope zoom actually do? The one that's in the "silver island"
I have had my Ultra since August, and simply assumed that this was indeed the periscope zoom, but this morning I noticed a very fine scratch in the corner of this camera. So I put it in 5x zoom, and saw that it didn't impact on the image. Then I realised that if I put my finger over this lens entirely, there was still no impact to the zoom!
So if we look from top, "Silver island" lens should be 5x zoom but covering it has no effect on any zoom level.
The next one down is the 2x zoom, interestingly if I cover this with my finger, it's mostly covered, but occasionally will jump to the main lens for a second or 2 for no reason.
The third camera is the main lens, this is also the one that is being used for 5x zoom and above, like they're taking a crop from that module as they did in my Mi Note 10 (and I assume the Mi 10 Pro, which I think is what the Ultra ROM is based off?)
And of course the final one is the incredibly poorly-positioned ultrawide
I've recently upgraded to Android 11 - MIUI 12.1.1.0 (RJJCNXM) so I've no idea whether this behaviour has always been the case, or if this upgrade has caused an issue.
I noticed that since the upgrade, the dots on the camera app for the "preset zooms" has gained a new option, a somewhat pointless 0.8x ultrawide which again just seems to be a crop of the ultrawide.
So, can anyone else test and confirm this? Has the latest upgrade "disabled" the periscope zoom?
Thanks
The periscope camera on Mi 10 Ultra is exactly what you'd expect, something as illustrated here.
It should kick in when you zoom by 5x and more within the camera app. However, I've randomly noticed (some months ago) that the app itself seems to behave in a way that if you zoom in over 5x and cover the periscope lens with your finger, the app will (temporarily) fall back to digital zoom using the main lens (3rd one from the top) even for higher zoom levels, because it assumes that there's something wrong with the periscope one.
In my experience, it would just automatically use the periscope camera when needed the next time I zoom, assuming it isn't covered this time.
If it doesn't, try to zoom like 10x and cover the main lens this time around, if it switches to periscope as it should.
Are you using xiaomi EU ROM?

Thanks for the reply. I feel like my phone is using the main 3rd camera for 5x zoom by default.
If I put the camera app into 5x zoom and cover the 3rd lens with my finger, the photo is obscured, if I put my finger over the periscope lens nothing happens
The same behaviour is displayed for 10x zoom, and any zoom up to 14.9x
However, once it goes into 15x zoom and above, you see "picture within picture" and the viewfinder does seem to be powered by the periscope, and the main 3rd lens is then responsible for the mini image in the corner, please see my attached screenshot, where I have covered the periscope lens with my finger.
So I guess what I'm wondering is...
1) Is my phone screwed?
2) Are 5x to 14.9x zoom shots taken with the main lens by default, by design or is this a bug?
3) Has this behaviour always been the case, or only since I upgraded?
I'm on Android 11 - MIUI 12.1.1.0 (RJJCNXM) which was an OTA update
If it's any use my baseband is c7-3033.23-0120_2103_79a330f and my kernel is 4.1.9.113-perf-gd722e10

Alright so I just went ahead and tested this (I use the EU ROM, but the camera app is just the same thing ported over).
What I found out is:
1. if I click 5x zoom in the camera app and autofocus is focusing on near objects (<1 meter), such as something on the desk I'm sitting at, it will default to main lens with digital zoom,
2. while still in the 5x zoom mode, if I turn the phone around and autofocus acquires focus on the opposite end of the room (~7 meters), the app will automatically switch to the periscope lens,
Which brings me to the conclusion, that:
1. the periscope lens has a minimum focus distance significantly greater than the main lens,
2. if you try to use zoom level of 5x and above, while focusing on an object relatively close to the camera (something up to 1 meter), it will fall back to digital zoom with the main lens, as the periscope lens is unable to obtain focus on such short distance
3. if you want to confirm this, avoid the automatic lens switching and make sure your periscope lens is operating correctly, you can use the Pro mode in the camera app, select the periscope lens manually on the right side (here it's called TELE 5X), and play around with it

Thanks so much for your help! Don't I feel a bit silly now But reassured that it works as I thought and I'm just an idiot
Hi everybody,i have search everywhere but did'nt seen similar case anywhere,my problem began after a litlle fall after this my camera started to behave strangely, like a reversal the motor brings out the front camera when I activate the rear camera and vice versa so the selfie camera works but only inside as you can see on the video, I already tried a factory reset.I also removed the back cover to check all the camera cables and nothing has changed except that when I disconnect the one from the front camera, the interface of the rear camera becomes "normal"
Thanks
summary of the situation the pop-up camera comes out when it should be in and stays in when it should be out

I don't know about the Poco F2 Pro but if it's something like the Huawei Y9 Prime with its pop-up camera it has a small magnet that "indicates" to the system when the front one is up or down and that makes the small motor that moves it activates the front camera, now the cell phone fell with the camera outside and the module was hit, it is possible that the state of the camera (down/up) has been "uncalibrated", in any case you would have to take it to a center specialized to be disassembled and checked because it seems to be a physical failure rather than a software one
thank you, indeed it is very interesting I had not thought of it did you see the video that I posted it is for this reason that I thought of a software defect but your proposal holds the road.
