Android 4.4.4 KitKat is now downloadable for Nexus 4, Nexus 5, Nexus 7 and Nexus 10 and in case if you haven't done it so, know what bugs that have been plaguing users worldwide and the useful tips on how to counter them based on user reviews.

Email Account Syncing

Syncing of the email accounts using the default application may suffer connection issues especially on the case of Corporate Exchange Server. A report from Google's product forum noted that the issue occurred on Nexus 5 running Android 4.4.4 KitKat.

One solution for the Corporate Exchange would be contacting the IT department of a user's corporate office to resolve the syncing problem. Based on the replies from other users, Android support team is currently working on it.

Battery Issues

Several users who upgraded their Nexus devices to Android 4.4.4 KitKat complained about battery issues including drastic battery drain, shorter battery life and even lack of power conservation while Airplane Mode is active.

1. Airplane Mode seems not helping on conserving power while active.

2. Wi-Fi connectivity still consumes power even Airplane Mode is active.

3. Shorter battery lifespan compared to Android 4.4.3 KitKat.

No Mobile Data

Another issue reported is the "no mobile data" connection on Nexus 5 running Android 4.4.4 KitKat. However, the dispute may have been related to APN settings stored on the smartphone. Apparently, the user who did upgrade the device to the new firmware seems to suffer no issues with mobile data before based on the details.

If anyone else suffers an issue with mobile data, contact the network provider immediately to determine if the values of the APN Settings are intact after updating to Android 4.4.4 KitKat.

Random Reboots

One user reported the "random reboots" on Nexus 5 running Android 4.4.3 and Android 4.4.4 KitKat. According the user's details, the smartphone was working properly prior to the mentioned firmware upgrades.
