Using the LED to know when a notification is available is of great use to me, but my new Sony Xperia Z appears to only turn on the LED notification light while it is on charge.

It turns orange to say it's charging, and turns blue (slow flashing) if I got a missed call or text message, but it will only do so while it's pluggin in. And to confirm I can get a missed call, wait for the LED to turn on, it wont, I put it on charge without disturbing it's 'locked state', and immediately I get slow flashing blue instead of 'charging orange', that is too say I can see before I put it on charge it should be on, but only turns on once i plug it in.

I like how it works while it's charging, but I'd like similar functionality while it isn't charging. I am using STAMINA mode, is this a battry save issue? How can I get the LED working as I'd like?

This is a known bug in Xperia Z (sources 1 and 2).

Currently the only way to restore the LED functionality is to:

  • de-select Settings -> Backup & reset -> Backup my data and Automatic restore
  • perform a factory reset from Settings -> Backup & reset -> Factory data reset
  • Complete the reset manually (that is, without restoring apps/data from the Google account)

Hopefully this will be corrected in the next update.

  • that is a scary fix that doesn't intuitively suggest why these steps are needed... can you elaborate? I like my google account data (contacts etc), don't want no data but have a working LED instead. If you can elaborate I'll definitely mark yours as the answer..

  • You can keep your Google account data (like contacts, calendar markings etc), but not the backup data (including which apps are installed, WiFi passwords etc). I have no exact explanation for this behaviour, but it seems from the second source link that Xperia Z is not the first Sony device to have similar trouble. Apr 9, 2013 at 13:33

  • sorry friend, but this app DID NOT fix the issue, LED did not work if not on charge, I added the app to the Stamina mode. Would have liked to be able to test more thoroughly, but only had 15 minutes after purchase to get a refund, and I needed it, issue still continures
