Little red light on the front

Chruwus — Wed, 16 Nov 2016 23:42:24 GMT

Hi there,
I noticed a little red light just next to the Sony label on the right, above the screen. What is that? It seems to be on whenever I use the phone.

Hi @Chruwus,

Welcome to the community,

When you put the phone on charge, is the light that shows up the same light that is showing?

Have you attempted to simply power the device down and then power it back up.

Let me know.

Hi Jake,

I don't mean the status LED that glows in different colors depending on unread messages or during charging. Just left of the LED is a light that is constantly on when the screen is Active, glowing red. Might be infrared, now I think about it... Maybe a distance sensor? But it is on whether I am calling someone or not...

Oh thanks!
Seems to be the case on all xperia x models? Still wondering why a brightness sensor needs to glow though 🤔

@Chruwus That's because you have enabled adaptive brightness so the sensor is on all the time.

Huh? Really? I have had the adaptive brightness on since day one (and in the last few days it even seems it started working as it had to, without going full dark) but I have never seen any red light. Should it be there under sunlight or all the time?

It is visible in dark areas and it should "breathe" every now and then, blink slowly.

Ahhh!!! I've seen it now! It shows only with the screen on, though. And it's very dimmed. That's why I've never noticed it before. All right then. Thanks.

I don't have adaptive brightness on and still get the proximity sensor glowing red but my case is a little different than the others, the sensor only starts glowing when my batery is 15% or less (at this level the phone notifies you your batery is too low). I have never used adaptive brightness so pleade don't say that's the answer. I think this is definitely a software bug which needs to be corrected.

@Edam94 I am not sure you are talking about the right led on the far top right or the almost not perceptible red glow typical of the lux sensor. Which one is of your concern?

Oh god you all are really dumb. Lol why do you answer when you dont kno. I hate humankind. Its a sensor for when you are on the phone. It shut off the screen so your face do not touch the screen by mistake. Try to put a finger right in front of it u will see ur screen go black. You are probably using an app like textnow or whatsapp. It doesn't end calls properly sometimes and the sensor stays on.

Hi guys, i just see the post at this moment. I really know what u are talking about, the red light at the right of the speaker. I spend about 2 minutes on observing that red light spot and then i realize that it glows whenever data traffic icon beside signal icon appears, and it goes dull each time data traffic icon disappears. Sorry if I have problem in English, wish u can get what I mean. 😉
