doubt front flash - Xiaomi Mi A2 / 6X Questions & Answers

Hiiii.
I have a doubt, why when I put the front camera and put the flash in automatic, it lights up like a flashlight? I thought I lit when I took the picture. Is there a method to activate it only when I press the button to take a picture?

As far as I can tell, it lights up when it detects there's not enough light. Try it. When it detects light, flash is on. But when it doesn't, for example when you point it towards a lamp, it turns off.
I think that's intended, in many cases the front flash can ruin a photo depending on surrounding lighting. If it's always turned on you can preview what your photo will look like with actual light.

[Q] Two modes camera flash

Here's my question, is there a way, to make the camera flash to use the normal light, and not the bright, when taking a picture, but in the same time, if a select it, to use the bright. It'll be usefull, because the bright flash makes things blurry or too bright when shooting from a close distance. If a want to take a picture of a business card (for OCR) I have to use separate light source, because the flash is too bright and makes it unreadable, and the normal flash is enaugh for the purpouse.
I too was interested in this idea about a month back. It would be very useful to take the photo with the standard flash light rather than the super bright flash. As it is this level that you focus the photo and expect it to be at, only to sadly recieve a horribly over flashed photo.
agreed...^^
What would really be awesome with the camera would be the ability to disable the light sensor. That way, in low light the FPS doesnt go to crap leaving us with blurry pictures. Also, the flash doing what a real flash does, being flash instead of stay on...
As for the normal light and not bright, hTorch has a toggle to go between both, we just need to see if there is a reg key or something to just enable the light without it going to bright mode for the actual shot.
There are a few other threads that talk about the camera reg settings, i just forget where.

Autofocus

Hi,
Almost every camera in the world has a halfway-click that focuses, measures the light and then takes the picture when you press the shutter button all the way.
On other phones (iPhone), where there isn't a halfway -setting, this is done by taking the picture when the user releases the button, which gives much greater control over exactly when the picture is taken.
Do you know of any program (camerazoom, snapshotpro etc?) that works this way? The stock camera app doesn't and it's quite detrimental to the quality of pictures you can take.
This means the camera needs to auto focus when I press the trackball button down and then take the picture within a split second when I let go of the button, since it no longer needs to measure light or focus. I would really love this feature.
Hi ,
Go to my thread http://forum.xda-developers.com/showthread.php?t=551904 the program I mentioned has this option also .
Thanks! Will check it out!
There is a workaround that i use that is effective on my mT3G. I turn auto focus off. That makes the camera focus at infinity. With these tiny lenses, infinity can start at less than three feet. So anything farther away than that is in focus if you turn off auto focus. I use SnapPhoto Pro to turn off the autofocus.
If you use SnapPhoto Pro autofocus, you touch the screen to focus and let go to take the photo. That works well. It also has a continuous focus feature which works very well but drains the battery.

IR Sensors?

Am I right in saying that there are four IR sensors on this device? I thought I saw one in each corner but lately, whenever I wave my hand over the bottom half of the phone, the screen does not light up.
Yes, if you want to see if they're all working, video record it with another phone or camera, you should see the IR sensors shining.

I tried with an iPhone and nothing came up...
Where is the fourth? Mine only has 3. Bottom two corners and upper right. Mine also does not light up if I wave over the bottom, but I can see the sensors firing, they give off a bit of red light. It's pretty easy to see in the dark, even with a naked eye.
There is only 3 and they are visible with the naked eye. Top right, and bottom corners.

I seem to remember mine working when I passed over the bottom, but now it is not. I can also see them glow red, but they don't seem to work anymore. Did yours ever work?
They never go right. The actual light is invisible to our eyes. You see the red dots when you catch it in certain light. But that's the sensor itself not the light its producing
Yeah my bottoms aren't working either, also if u go into attentive display, it doesn't work for me, the picture never pops up. Anyone care to give it a try, I haven't took the update, didn't know if that was anything for it.

Yup. Maybe an update broke it? I know it worked when I first got the phone then I turned it off.
Edit: they do turn on when I approach the phone. So I know they work.
I hadn't took the update so that's weird, idk hopefully it will be figured out. I see the sensors light up so their working I just can't figure out what's going on, glad its just not my phone.

The red dots go on and off when you move across the bottom of the screen. It's definitely not the sensor itself, because if you hold it in the same angle, the light also goes off.
As far as the bottom of the screen, mine has never lit up my screen by reaching across the bottom. I think the bottom sensors work in conjunction with the gyro, so that when you pick it up it turns on, but the sensors themselves never turn on my phone. If I wave across the upper right one it will though. It's been this way on all 3 Turbos I've had.
The 4th is near the middle on top. You can see them in this video.

The bottom sensors only work in a dark room for me. When the turn on they go bright then dim, and then they will sense my hand. Try it.

Q) the front camera can't take FULL "wide selfie"

Hello, I don't know If its supposed to be that way. But when I first heard of the "wide selfie" thought to myself wow I can now take a full picture of the background.....hope turns out I can only turn ONE direction. Not both. And fractly like that its pointless
In wide mode if you start with yourself center frame and tap the camera icon it will instruct you to turn the camera slowly either left or right. If you do so until it beeps you'll be prompted to go the other way to capture the other side. Obviously if you dont go until the opposite direction prompt then the capture will end prematurely and you'll only get half of the shot.

camera: white screen

While on holiday, quite often at the beach, when switching on the camera, all I got was a bright white screen (like the lenses couldn't cope with the bright light)
After I put my hand over the lenses (to create darkness) and removed my hand, they were able to see an image.
Anyone else experienced that?
