Lock screen icon question

This is the standard iPhone X lock screen, with the flashlight in the lower left and camera in the lower right. (I made this photo black and white so it could fit in this post. It is otherwise correct and accurate.)

If you're asking about the horizontal bar under the battery - Wi-Fi icon, it is to indicate that is where you swipe down to see the Control Center.

Do you see something different? It is likely not the traditional lock screen. It would be very helpful if you posted a screen shot.

Look for the camera icon where you are typing.

The iPhone X screen captures are very large. You are restricted to a 2MB file attached to your conversation. That's why I had to make the screen capture black and white above.

If you're asking about the horizontal bar under the battery - Wi-Fi icon, it is to indicate that is where you swipe down to see the Control Center.

I don't know the answer yet, but I'm glad to see your screen shot!

Do you have any accessibility settings on (Settings > General > Accessibility) other than those that are set by default on the iPhone X?

When replying on the iPhone, I see the camera icon in the lower left.

So you see two sliders without any further explanation about what they are? Hmmm, I'll continue looking ... but a screen shot if possible would be great.

OK, I think I've figured it out!

Indeed that is exactly what you are seeing - those "on/off sliders" as you call them are exactly the Control Center icon!

The above comes from this article:

So my guess is that at one time (perhaps even now), you ran or are running a beta version of iOS 11 and/or iOS 11.2 that contained the Control Center icon, which is now gone.

I turned on Low Power Mode (I admit I've never had it on before) briefly on my iPhone X and did not see the switches.

I'll keep looking ... You've got me curious.

Glad that worked out. It was an interesting brain teaser.

Enjoy your new iPhone.
