LED on Xperia Z only in operation while charging 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 -&gt; Backup &amp; reset -&gt; Backup my data and Automatic restore
perform a factory reset from Settings -&gt; Backup &amp; reset -&gt; 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.
