Google's new Android 4.4.3 KitKat update is plagued with bugs, according to recent complaints by owners of the Nexus 4, Nexus 5, Nexus 10, and Nexus 7.
WiFi connectivity issues have affected Nexus 4 and Nexus 5 users whom have had trouble with lagging internet speed after installing the latest Android 4.4 KitKat software. Of the two hardware upgrades, the Nexus 5 update has taken the brunt of the complaints.
Nexus 4 owners have also reported random reboots and auto-brightness problems that were already present in the previous Android 4.4.2 KitKat update. The Android 4.4.3 KitKat update was supposed to have addressed both of these bugs.
Meanwhile, the Nexus 7 and Nexus 10 users have reportedly been experiencing bugs with battery life and notifications. Other bugs reported include problems with exchanging email and 3G connectivity. Even so, it seems that the issues are happening at random, and that not everyone is reporting the same issues.
Nexus owners encountering random bugs with the Android 4.4.3 KitKat update are advised to do a factory reset on their mobile devices. It is likely that Google will soon release a small hot fix, and may be holding off the Android 4.4.3 KitKat roll out on other mobile devices as well.
The Android 4.4.3 KitKat update began rolling out for the Nexus 4, Nexus 5, Nexus 7, and Nexus 10 over two weeks ago. This roll out later extended last week to Motorola's Moto X, Moto G and Moto E -- though reports of bugs have curiously not surfaced online. This is not to say the Motorola roll out is bug free, but to merely suggest that bug issues will take time to be reported.
Rumors also indicate that the Samsung Galaxy s4 and Galaxy s4 will be getting the latest Android 4.4 KitKat version as well. Still, the recent debacle over at Google suggests that an Android 4.4.3 KitKat update roll out for Samsung devices may be delayed. The new Android 4.4.3 KitKat update is mainly a bug-fix, and will not bring any significant changes to the existing software.
Those changes are reportedly being reserved for the rumored Android 4.5 software, said to be replacing the Android 4.4 KitKat. Though there is much speculation, no nickname officially exists at this time for the Android 4.5.
