Yeah it's still there, with color choice by app and everything as in the Xperia 5 MkII.

Yes, the LEDs flash in different colours and intervals depending on the app and message, as with the previous models.

Ah great, thank you very much for the quick answer:)
I wanted to buy the 5 v-model, but it seems that this led-notification is no longer available, which is a real no-go for me, I find this function so practical...
