Notification LED is not working

[Tor]

Hi everyone,

I updated my Xperia Z to 10.1.1.A.307 on Tuesday. After update, notification LED worked properly. But I realised today that Notification Led is not working now. Stamina Mode is off and I don't know what to do. I've read many post that said that I have to restore my phone, but I don't like that solution because I don't wanna lose my contacts, SMS and applications. So, is there any other solution to this problem?

Thanks in advance.

PS: I've found so many bugs with my Xperia Z and I'm very disappointed with Sony since there is no solution to those bugs. I think that Xperia Z will be my last Sony product

I can do so many things, but it's very annoying formatting the phone due the notification light. Anyway, I've already formatted it, and I've lost so many things e.g. facebook contacts linked with my own contacts and so on...
