Have you gotten your hands on Google’s latest in Android 4.4.3 KitKat? The update is slowly making its way to Nexus and Motorola devices at the moment and provides a new dialer, and some changes to the contacts list (creating more of a Gmail redesign). Android 4.4.2 KitKat brought problems such as camera app crashes, Bluetooth connection issues, and, of course, the never-ending battery drain problem. Sony just sent the Android 4.4.2 KitKat update to its customers a few days ago, and already, some of our readers are experiencing battery drain.

The Android 4.4.3 KitKat update was meant to fix Bluetooth connection and Wi-Fi issues, improve the Nexus 5 camera autofocus, as well as audio quality and dropped calls. Experienced Android users are also noting that the mm-qcamera-daemon bug in Android 4.4.2 KitKat still exists in Android 4.4.3 KitKat, so Google’s likely got another update to Android 4.4 KitKat that’s still in the works.

If you’ve not yet received the update as a download, you may want to wait. There are a number of problems with Android 4.4.3 KitKat, random problems that range from LTE/3G signal issues to dropped calls, app crashes, and major battery life drain.

Some cases are isolated, such as the Google Play Store app crash one user noted in a forum posting. Others are more common, such as 3G and LTE data problems along with phone signal and reception issues. In one Google forum posting, a commenter said that he’s struggling to get 3G on his Nexus 4. In another site forum, a user said that his Sprint LTE was now struggling to stay on LTE (on an unrooted device at that). Others are noting problems with AT&T data as well – suggesting that the LTE data problem is related to the Android 4.4.3 KitKat update and not issues with Sprint or AT&T.

As for the battery drain, a number of users are experiencing this issue – which isn’t surprising (at least to Sony and some Samsung customers who had issues with their Xperia Z and Galaxy S4 models with the 4.4.2 update). In some cases, clearing the cache helps; in the majority of cases, it doesn’t, even after the users follow the instructions to clear their cache. One user notes his frustration with his battery drain: “Took the phone off the charger at 6AM. It’s 3PM now, and my battery is down to 41% and I’ve used it less than I usually do (only 1 hr., 15 minutes, no calls)…down to 36% since I originally wrote this message. That’s 5% in 15 minutes. Never did I have such drain before…”

One particular app that you may want to be aware of that teams up with the Android 4.4.3 KitKat battery drain would be the Amazon Kindle app. Yep, it’s draining significant battery life for individuals whose smartphones contain no root whatsoever. One user, Jeffrey, notes that “the first day after the update my battery drained in 3 hours and the phone was really hot!”

We here at Inferse want to warn you about what other Android users are experiencing with 4.4.3 KitKat. As it’s been said by a few reputable sources, Android 4.4.3 KitKat fixes some problems, only to bring new ones. Apparently, Sony’s claim that Google is to blame isn’t too far-fetched.
