Sony Mobile released the official Android 4.4.2 KitKat for Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact which updates almost everything and featured new apps. However, there are five major bugs included in the update that may not be fixed completely.

Overheating Issue

Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact boasts quad-core Qualcomm Snapdragon processor chipsets which means they process data faster compared to other Xperia smartphones. Such processing intensity may cause overheating problems and even the camera might also generate heat.

Depending on which apps or camera modes you use, both the processor and the rear camera may release too much heat. It is best to play 3D games in a ventilated area and use manual mode to most camera captures.

Battery Drain

Sadly, Android KitKat drains more power compared to Android 4.3 Jelly Bean on Xperia Z series and could be related to the apps or camera modes featured on the firmware. By default, Android 4.4.2 should have better battery life compared to previous Android versions, but it is totally dependent on software optimisation.

Additionally, overheating may also burn power and that is why experts suggest that users should keep the device cool to save more battery.

Sony Mobile will release a bug fixing patch next week, which may contain battery enhancements or improvements to the STAMINA mode.

Sluggish Camera

Android 4.4.2 KitKat features an updated camera UI with additional camera modes. Some users reported that the camera UI responds relatively slow when selecting camera modes or during navigation throughout the app.

Sony used a specialised camera lens or sensors which may slow down the camera app or selection of options whenever the hardware is being accessed. A firmware update with optimisation on the camera app may fix such issue.

Audio Bug

Recent reports revealed an audio bug on selected Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact models which affects the internal speakers. Users are unable to hear the sound from calls, notifications, alarms and even the music player.

Sony Mobile will include a fix for this bug in a firmware update scheduled next week starting in April 7th.

Memory Card Restrictions

This is not exclusive to Sony Xperia Z series running Android 4.4.2 KitKat, as Google made the new Android version restrict SD card writing. SD cards are now facing restrictions in Android KitKat and limits writing capabilities of third-party applications.

Third-party file manager won?t be able to write on the memory card or download cache files from other apps such as TomTom that provide maps. The only workaround is to root your device and use SDFix: KitKat Writable MicroSD app. However, rooting the device will cost its warranty and rooting kits for Android 4.4 KitKat are still scarce.

Four of these bugs are fixable via software improvements and enhancements, but Android KitKat users will not be able to modify MicroSD card restrictions without rooting their Xperia device.
