Sony Xperia Z1, Z1 Compact, Z Ultra Android 4.4.2Android 4.4 KitKat update finally arrived to Sony Xperia Z1, Z1 Compact and Z Ultra. But, we now know that the update affected some units, by introducing a sound bug. Sony is aware of this, and a statement was released which said that there will be a fix in the form of a firmware update.

The bug is not something small, it’s actually a serious issue, because for some users it makes alarms, notifications of videos silent, and of course, piles of requests fell on Sony to fix this. The company is now aware of the issue, and as specified above, a statement was released claiming that the fix is in works.

The fix will apparently be released beginning April 7th, but of course, timing and availability will vary according to each operator. Aside from this bug, there is another limitation that the 4.4 update introduced for the above mentioned Xperia devices:  before the 4.4 update, users were able to store third party apps on their microSD card, but once the KitKat update is installed, only images and other media will be stored on the microSD card.

First party apps can still be stored on card, and developers are able to bypass this problem by creating folders on the microSD cards, but the problem doesn’t completely go away since once an app is uninstalled, all its data is lost.

Is it actually worth upgrading to Android 4.4 at this moment? With the sound bug still there, probably many people would give a firm no, and it’s a decent decision. What about you? Tell us what you think in the comments section below.
