[Q] ipad 2 proximity sensor like function

Hey I was just wondering if it is possible to gain the same function as the iPad 2 has with its proximity sensor with our gtablets since we have a light sensor?
I'm not sure if it has already been asked before or if the devs are working on something similar but to me it would just make our already amazing tablet even greater

I'm not 100% sure, but I think a proximity sensor requires both a transmitter and a receiver. I assume IR.

I think iphone & ipad use light sensor to make a trick on the proximity sensor, if the light get completly darken it will assum that the device is close to a hard surface, ie: the face in the case of the iphone, so i assume that it will be posible to do so with a little software trick ... btw, anyone know which ROM take the advantage of this light sensor setting in use? don't see it on Vegan ..

Sensor behind the display? Looks almost like a dead pixel

Hello, I just bought a gear s2 classic and noticed something strange on the screen. When the screen is off and you look under a bright light, there looks to be a sensor in the center of the screen, which almost looks like a dead pixel. I included a pic but not sure if you can see it. Is this normal or should I exchange it? Thanks!

Don't worry, this is normal - no need to exchange it :good:

Yeah. That's a sensor.
Ambient light sensor. Adjusts display brightness to compensate for bright conditions.
Be thankful!

[Random Idea] can ir blaster besides ir camera be used as remote.

poco has great hardware but it can be used to its extreme. and one of those pieces include The IR emitter and sensor.emitter can be manipulated to be used as regular IR blaster which requires some deep level coding.

What IR emitter? There is none. The device has an IR Camera, which captures infrared - it doesn't emit anything.

I thought there's an IR emitter between the IR camera and earpiece? If not, how would face unlock work in total darkness?

There is ir emitter, if one can't see it working and lighting up then consulting a doctor is better option.
Edit- don't know how ir camera but it lights up in dark for face unlock

Do you mean human eye can see infrared?

Even when it's 100% pitch black, anything with a temperature above absolute zero will emit some IR radiation.

I don't think it was necessary to call me blind lol. But OK, that's weird - I thought it wasn't necessary these days. They developed thermographic face detection years ago, works fine in 100% darkness without needing an IR LED to act as a "flash".

Infrared does leak a little bit into the visible-red, yes. If you look at night-vision-capable security cameras at night you can see a faint red glow from its IR LED's. They're needed on security cameras so it can be 100% clear on everything, regardless of a heat signature. At least that's how I remember it.
But as I said, I find it strange that it needs an IR LED for thermographic face detection. Maybe it's not actually a thermographic camera and that's why it's not very secure, dunno. But I digress.

It uses simple face recognition not any fancy thermographic face recognition it uses to illuminate the face in the dark comming to the led as hardware is concerned yes you can use that led as ir transmitter for a remote but it should be able to accessed by developer so that the app can talk with it but I don't think it is possible with current access

Or you can just get a usbc IR remote for €3 from AliExpress and use that.
Pretty sure that the IR from face recognition doodad ain't gonna be ideal for remote control purposes.
If it were Xiaomi would surely have included IR blaster functionality

Light sensor?

Maybe I'm just stupid but can anyone tell me how does the OP7 Pro senses light for the adaptive brightness? Since there's no notch or space for light sensor on top due to display, how does it work?

I'm pretty sure (maybe...lol I know it's at least the proximity sensor) this is the light sensor and the proximity sensor all in one.

Light Sensor is under the screen, proximity sensor is built in the speaker

Does the OP7 have under screen sensors?

Was at the beach... in direct sunlight, max brightness, white screen, I not only see the fingerprint sensor circle where it should be, but I also see 2 smaller circles... maybe an inch from the top of the screen and on the right side.
Does anyone else ha w these? Make sure it's bright enough so you can see the fingerprint scanner (if you can't see that, then you won't see the smaller ones).
I know the Pro has an underscreen sensor, but I thought the 7 was like the 6T.. next to the camera? Or did the 6T have it under the screen, too?
Why are there 2 circles?

Verified with another camera that there's definitely an IR sensor there (at least the left of the 2 circles).
Not sure of it's for light or proximity, or what the other one is. Weird they did this for the 7 but not 6T?

Yes, we have prox sensor and light sensor under screen. Why we have it in op7 but not in op6t? Maybe before the cost was so high or efficiency so low
