small red light on Proximity sensor when 3g/4g data transmission

ZeroWolf_khv — Mon, 25 Jul 2016 13:42:42 GMT

Hello, community.

I found a little "bug":

When 3g/4g data transmission in progress, small red light on Proximity sensor is lights up.

I can see this light only when up/down arrows appears near the "3g" / "H" / "4g" symbol.

Is it a hardware error or software bug? (Can fix This anyway?)

Or it's a normal ?

My English is not so good, so you can see a picture

That is just the sensor being active, doesn't have to do with any form of connection, but with the lighting conditions of the environment.

Post about fact, that this sensor being active exactly when icon of data transmition is active. I think is so strange

I've noticed it being active with wifi too, just check it in a dark environment.

Blinking light

So sometimes when i am on my phone a little red light that isn't the notification led starts to blink very rapidly. I figured out it is something to do with the front facing camera since opening the camera app makes the light go fully on. I was curious if anyone knows why this is and how i could stop it, as it's growing rqther obnoxious.

@xChayra That is just the proximity sensor with adaptive brightness enabled. See this thread and read:

Hello, my smartphone continues to show a red look. I have disabled the light sensor. The red light flickers now very fast. The red light stops only when W-Lan or Bluetooth is switched on or no SIM card inserted. Is this a software bug? Sony can not give me an answer. My Firmware is 35.0.A.1.275 Sony X Performance.

Hi.
I have the same problem,i think this has nothing to do with adaptive brightness. i tested it so many times and it happens only when mobile data is on. when making a call it's normal thing blinking that sensor.but with mobile data it's strange.idk but i feel like battery draining fast too.here is little video about it - https://www.youtube.com/watch?v=UZFsB9b5p6g
my device is xperia x dual F5122 , software 34.0.A.2.292
is there any solution? i also repaired software. will this go away with android 7 nougat? or i have nothing to worry about.but im a little concerned. thank you!

Hi all,

Just discovered the 'small red led', Google is my best friend and brought me here.

I'm using a battery app, which allows me to set 4 quick type's off brightness,

- Full power

- Half power

- Low power

- Automatic

Only when I select automatic the red light will appear.

brother man that's the problem... just switch n the data (mobile data) then see with whatever settings you've in your phone...if the redlight (proximity sensor) blinks while transferring data(while sending & receiveing data)..then we're on the same page...post a pic if possible...nobody has a solution yet.

Not only when data is on but Proximity sensor is turned on even on lock screen (after waking up device) and at that time sensor is turned on irrespective of data/WiFi.

Is it a feature or bug?

It's a bug i guess because none of my xperia's or other branded phones had this problem...this is having this problem...i don't know if sony officials sees this page and our issues...and i think this proximity sensor thing just consumes a awful lot of battery.
