Hi @WAQU,

I'm sorry to hear that.

Could you test how your LED notification light works in the service menu? To do so open the phone app then enter *#*#7378423#*#*, then proceed to Service Tests > LED. Does the light cycle through the different colours in this test?

If it does, could you try rebooting your device to safe mode to see if this behavior is caused by one or more of you downloaded apps as these will be temporarily inactive in this mode.

Let me know how it goes.

Hi @wizin and welcome to the community.

I'm sorry for the late reply. I'm sorry to hear this. Is it the same if you restart your phone to safe mode?

If it is I would recommend that you perform a software repair using Xperia Companion.

Let me know how it goes.

If you are still experiencing the same behavior after doing a software repair using Xperia Companion, this behavior is most likely hardware related.

I would recommend that you get in contact with your Local support team for assistance with having your device sent in to an authorized service center for further troubleshooting and repair. You local support can also assist you with questions regarding service routines.

Let me know how it works out.
