Sony's waterproof Xperia Z smart phone is plagued by a power glitch that sees the enormous 5-inch blower stopped dead in its tracks, according to disgruntled forum members. But Sony claims the bug only affects a "very small number of devices".
Xperia Z owners have been taking to Sony's official forum for the last few weeks to complain about the issue, which seems to see the quad-core phone suddenly powering down without warning.
"I've only had my Xperia Z a day and it's totally dead," the first poster explains. "My XZ (black) is ok but my girlfriend's white one died three times today," another says.
"Got my Xperia Z yesterday," one unhappy owner comments. "Everything was fine 'til the morning. Tried turning on and didn't do anything. No light when plugged in charger as well." Some commenters have reported repeat instances, while others report that the phone can be resuscitated by holding down the power and volume buttons.
A Sony support member posted in the thread to say the problem had been identified. "A fix for this will be implemented in next software update for the phone," they said.
They said they weren't able to give an estimate on when that update would arrive, though a thread on XDA-developers reports a software update (10.1.A.1.434) is now available. It's not clear whether this update has fixed the issue.
In a statement Sony apologised for the glitch, saying, "We are sorry that a small number of our customers are experiencing power issues with their Xperia Z.
"We would like to reassure all of our customers," the statement continues, "that this is affecting a very small number of devices. If you have experienced any issues, please contact your local customer support centre who will be able to advise you on some easy steps you may take to resolve the issue."
