"The much anticipated Android 4.3 update, released earlier this week, has caused headaches for thousands of Nexus 4 owners as several incompatibility issues emerge.
Signal loss, continuous reboot loops, application bugs and battery life issues are just a few of the myriad of problems reported hours after the update was released.
However, the majority of users on Google’s Product Forum have reported Wi-Fi connectivity issues, which include automatic toggling between enabled and disabled Wi-Fi and the failure of the Wi-Fi icon to appear on the notification window. In more extreme cases, users reported severe overheating and even bricked phones."
