Yes, you are possibly right

I have the same problem. After updating to Android 7, the LED will only light when charging.

The problem is when messengers are muted, so no notification sound.
If you have a silent notification, put it on and LED will work.

I want this LED because I do not want to hear any sound.

In this thread was a hint from Jildert, there is a notification called silence.mp3, no sound. Just the field notification is filled.
So messenger remain without sound.

It is a shame that we must install an external .mp3 to correct an issue of Sony!

The worse is that Sony doesn't give us an answer, neither to inform us about the issue's knowledge.

This happens also with Facebook and Twitter.

Totally messy and usually I never login for forum.

I thought that is broke but if I add this code

    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    mBuilder.setSound(soundUri);

then this is fix. lol ....

?

Ad this code?

[Alessio_841]

Hi @3dkkm,

By adding this code the issue is fixed?

Did you try before?

How to add the code?

Thanks!

Hello Sony. Is there a solution now? I have reset my z5 compact today again. The notification LED does not flash on any app. (I tried email, whatsap, sms, signal) 

Only when i charge the phone the LED-light is on. Please help me.
