Why use the fingerprint reader when volume down works as shutter?

Is there a way to select second camera?

Hi, I'm looking for a way of selecting secondary (telephoto) camera, or just a way how to recognize which camera is taking photos (I'm doing test with finger over camera now )
I know about "x2" icon, which does: "select tele lens, if you have enough light, but use digital zoom of main camera if you want. But don't tell user, which camera is active any way!"
Thank you for ideas!

Open front facing camera --> Settings --> mirror reflection

When using the front camera the scene looks mirrored. When taking the picture and opening it it looks flipped vertically. Is there a way to see the image on the screen of the camera app the same way as it will appear after taking the picture?

Love the new quick launch feature on the OnePlus 6T. Here's how to use it!

Unlike other OEMs out there that use the in-display fingerprint scanner to just unlock the device, OnePlus actually gives you the ability to quickly launch other apps as well. That's just frigging amazing and I absolutely love it. You can check the full tutorial here - https://themrphone.com/article/oneplus-6t-quick-launch-apps-screen-unlock
Kind of a bummer that you still need to wake the display in the first place to actually use the in-display fingerprint scanner, but still, this is good nonetheless.
Nice, thanks for info.
Yes, completely agree that having to wake the display in the first place to actually use the in-display fingerprint scanner is a bit of a step back. Fingers crossed for a Magisk module!
tmobile version doesn't have this yet. just so everyone knows.

I think I'll be using the "touch to wake" option

The screen has to be woken in order to light your finger. UD readers use a camera behind the OLED panel to take a picture of your fingerprint, and the panel is what actually lights your finger for that shot. The only compromise I could see would be something to keep the rest of the screen dim/blank and only activate the fingerprint area, but it'll still require you to wake the screen.

Yeah, aod is probably something that can do the job at the lowest acceptable lighting requirement to read the FP.
My "Settings" app carashes when I try to enter on that menu (quick launch)... What should I do?

When you touch the fingerprint reader area the pixels behind it light up to 100% brightness in order to illuminate your finger.
The "tap to wake" feature already available pretty much solves this "problem". You simply press your finger onto the "off" display in the place where the fingerprint reader is located (easy to do after some practice) and the display turns on, fignerprint scanner illuminates and reads your finger which then unlocks the phone.

I do hope they tweak how bright the screen has to be, but from all I've read, those pixels have to be at full blast to get an accurate read on the fingerprint., so they probably need to at the very least need to regionally brighten that area of the screen fully on the ambient screen. Someone out there more clever than I will surely figure it out in a way that doesn't compromise security. Hoping it's OnePlus, but we've got an incredible community that can take a swing at it too!
Mine do not have any such feature..
Though the feature is cool I am not happy with the experience. It's not smooth, it shows pattern input screen for a while before showing quick launch menu.
Also the home screen/last app screen before the quick launch and the vibrations (too intense) are also bummer
What version of OxygenOS are you on? I'm on 9.0.3 and I don't seem to have the Quick Launch option?!

Hello mate!
I've already solved this by enabling the apps that I disabled before (like Google Pay, Google Music/Video and a few others). Then, once the quick launch worked, I disabled again those apps. :good:
still waiting for 9.0.4 to have this

TMO variant is missing quite a few other things, to be precise

by default, the quick launch is set to open a few google apps preinstalled on the device.
If you disabled/removed some of them, but didn't remove them on the quick launch list before that, then it's going to crash every time you open the quick launch setting.
Enable every default app and try again, if it still doesn't work then factory reset and next time remember to remove all apps in this setting before disabling them.

That's why I keep going back to the intl firmware. Quick launch and OnePlus lab. Phone feels much more premium and snappy with intl

Is there a way to use the 3x optical zoom lens?

Using 3x zoom in the camera doesn't switch to the 80mm lens. It just gives a crop from the 40mp main sensor.
Is there a way to actually use the 3x lens?
In my case to make it work I force Focus, after that i can see the swap between lenses.

How do you force focus? I tired manual focus and it still didn't change lenses when going from 1 to 3x

Just tap somewhere in the picture and it will change to the optical zoom lens.

That doesn't do anything but use a crop from the 40mp sensor to give a fake "zoom". You would get the same results using the 40mp mode and cropping the image yourself
I'm convinced the optical zoom lens exists for nothing but marketing. The only lens on the back that is ever used for any photos is the middle lens.
Maybe it is something weird with mine. You can check this by covering the other lenses with your finger

You must use it in enough bright environment because it won't switch to zoom lens when it's not enough bright.

Dude, everyone can see the lens switching, the telephoto one have OIS, i use the zoom all the time, if i cover the telephoto lens i cant see anything, so yes the telephoto is fully functional and not a made up marketing, in pie they even added a toggle to the HDR mode so you can get HDR pictures using it faster. (in adroid oreo you can manually zoom until 3x on HDR but now alot easier). the only times you cant use it and the phone will switch back to the main lens, is:
1. At Night or when theres not enough light.
2.If you try to focus a object that is just too close.

I was wondering why my indoor 3x zoom pics were so poor. I had tried covering the zoom lens in the past, proving that it actually does switch between the two lenses. What I didn't realize until now, is that when the camera doesn't have enough light, the zoom lens isn't used and the 3x becomes a digital zoom using the main (middle) lens. You can easily see this by turning on the 3x zoom, covering it up, and shifting a live view from a bright window to a dark area inside - when pointing outside the lens is blocked, but when you swing around and point the camera inside you can see the image (because it is no longer using the 2x lens).
That explains the poor indoor zoom shots I've been taking - thanks!!
Now I still need to find out what the monochrome lens is actually doing in colour photos. Playing with blocking the lens only seems to have an effect in monochrome mode, but it is supposed to contribute to capturing all photos. Any suggestions...?

Manual Focus on Exynos Camera

With the advanced mode of the camera,
is it possible to use manual focus with the wide angle and zoom lenses with the Exynos phone?
Thank you
Do you mean focus lock, where you can click on the subject and it will hold that focus, or are you looking for a slider so you can manually adjust focus?
