No LED notifications

Nk87 — Thu, 15 Dec 2016 04:59:35 GMT

Hi guys I've had this phone for a month now and mostly enjoying it. I have noticed since about 5 mins of having the phone I initially had led notification lighting up but after set up / installing my data I now don't get any led notifications for anything. Is this normal? Was I imagining the led notification or is there meant to be one? Any fix? Thank you

Just to add it doesn't illuminate at all while charging or with low battery warning.

Hi @Nk87,

You were not mistaken, there is indeed a LED light placed to the upper left on the phone's front (number 1 on the picture below).

If it doesn't illuminate, even when you charge your device, I'm afraid that this could be hardware related. First of all I'd recommend that you try rebooting your phone into safe mode though, to make sure that this isn't caused by any third party app.

Oh no I just restarted in safe mode and all I got was a weak red light around number 7 on the image. I think it's where the flash should be. The red light would come on briefly with the charger in and stay on a few seconds with the screen off then turn off. Does this mean there's a hardware problem?

I also just went through all the diagnostic tests and they all passed.

Number 7 is the proximity sensor and does illuminate slightly,
Number 1 is the main led and should be much much brighter whilst charging and when getting notifications.

Did the number 1 led illuminate during the diagnostics?

No led came on. Just a faint red from point 7. I did the full diagnostic with no faults. I also tried safe mode with no difference made to led and a full reset. I think I'm going to have to send it away. Any experience of turnaround time for Sony or how it works? I guess this is not the best time of year in terms of service times.

But the diagnostic for led asks if the led illuminated?
So how could it have no faults if no led came on?

I don't remember there being a diagnostic for the led. There was one for a flash with camera but not for led. I'll check again now but I'm sure there wasn't one.

There isn't, Ive just checked again.
I would suggest you contact your local support as it does seem to be hardware related.
You could try a repair installation using Xperia companion first, just to rule out a dodgy bit of software.

I did something with the companion thing already. I think it might have been the repair but no joy. I'll have to give them a ring tomorrow in that case then. Thank you

For all Android's famous customisation, I find the LEDs to be useless because I cannot switch them off for Gmail. Thus they flash for emails as well, when I only want to be notified of SMS, calls and Whatsapp messages when my screen is off. As my LED is often flashing to alert me that I've received yet another spam or low priority email I find the feature pretty pointless. Sure I could switch off Gmail notifications altogether, but I do still want to receive the banners....just not the LEDs. So I doubt that I would send my phone off for repair if this was the only fault. YMMV of course.

@Nk87 @Viridis @Sunking101

There should be a test for the LED together with illumination if you dial *#*#7378423#*#* and go to service tests.

Re: No LED notifications

Nk87 — Sat, 17 Dec 2016 13:09:40 GMT

Is the illumination /LED where I'd expect the led to come on? I just tried it and the screen flashed from bright to dim but no led. Does that mean it's a hardware problem?

Re: No LED notifications

_alexdon_ — Sat, 17 Dec 2016 13:14:11 GMT

Have you pressed the screen @Nk87? If yes and the LED still won't turn on, it's hardware.

Re: No LED notifications

Nk87 — Sat, 17 Dec 2016 13:17:48 GMT

I tried it again and it definitely didn't come on. Thanks for all your help!

@Nk87 Sorry to say but it all points towards this being hardware related then. Your Local support team can give you more information on how you can proceed with this from here.
