Android 4.2 Jelly Bean Bugs Plaguing Nexus Users

It seems Google’s latest Android update, the new Android 4.2 Jelly Bean update that was released earlier this month, is tormenting some Galaxy Nexus, Nexus 10, Nexus 7 and Nexus 4 owners with an assortment of bugs.

Users of Google’s latest operating system, Android 4.2 Jelly Bean, have been complaining about several bugs, some minor and some major, in the days since Google started rolling out the update. This is a far cry from the near flawless update that is and was the Android 4.1 Jelly Bean update that touched down earlier this year.


Android 4.2 is causing issues for Nexus users.

And while we had heard about some minor bugs with the Android 4.2 Jelly Bean update, the voices have become so loud that it’s impossible to deny that Google has some software issues that it needs to deal with.

Nexus 4, Nexus 10, Nexus 7, and Galaxy Nexus owners, who are the only users to have received the update thus far, are reporting several highly visible issues that are seemingly tarnishing their experience with what we consider a fantastic update. According to a compilation from Android Police, users are experiencing everything from random reboots, to Bluetooth issues, to abnormal battery drain.

Here are the bugs that appear to be plaguing Android 4.2 Jelly Bean users.

Random Reboots

Owners of the Nexus 10, Nexus , Nexus 4 and Galaxy Nexus are seeing their devices reboot randomly, which means without any user provocation, after installing the Android 4.2 update.

For some users, the reboots happen once or twice a day, for others, more than that. It appears that Nexus 10 owners might be the worst off as some are saying that they are seeing upwards of three reboots per day.

A complete wipe of the device seems to fix the issue though that is obviously not going to be the top choice for those who are experiencing the bug.

Stability Issues

Maybe even worse is the fact that some owners, besides reboot issues, are seeing slow down in the user interface and when opening applications. The sluggishness has apparently taken the buttery feeling aka the smoothness out of Android Jelly Bean for some users.

Google Now is also apparently slower than it was in Android 4.1 Jelly Bean and users are also seeing their clocks off by several minutes from the actual time.

As for the application bit, it seems applications are crashing for Nexus users on a consistent basis. Now, this could definitely be an Android 4.2 Jelly Bean issue but it’s more likely that the developers have been slow at patching up their applications for the latest update.

We’ve heard from plenty of Nexus 7 owners who are saying that they are seeing app stability issues but those will likely be fixed once developers offer updates post-Android 4.2.

Bluetooth Problems

We heard from numerous Nexus 7 owners over the weekend who complained about Bluetooth issues. Connections get lost, the sound is choppy and bad, and some can’t even get it to connect at all. We saw this with the Galaxy Nexus with the release of Android 4.1 Jelly Bean and Android 4.2 has apparently just made things go from bad to worse as far as Bluetooth is concerned.

It should be noted that that most Nexus 4 owners aren’t seeing issues with Bluetooth and the issues seem to be plaguing Galaxy Nexus, Nexus 10 and Nexus 7 owners.

Auto-Brightness Bug

Nexus 7 owners have also been telling us that their Nexus 7 and other Nexus devices are experiencing a bug with auto-brightness wherein the feature just seems to automatically adjust itself without any sort of reason. We’ve heard from people who say that the devices will automatically turn the display down, even it’s not necessary, and then bring it back to normal lighting levels.

Android Police also notes that some people are experiencing screen flickering when auto-brightness is still on but that bug has seemingly shown up in many iterations of Android and can’t be blamed on Android 4.2 entirely even though Android 4.2 users are seeing it.

This could certainly be a reason why some people are seeing the next bug.

Abnormal Battery Drain

Nexus users are reporting abnormal battery drain with Android 4.2. Apparently, some of the Google Play Services are gouging stand-by battery life on the Nexus 7 and Galaxy Nexus to the point where users are seeing a upwards of a day of stand by time lost.

It appears that exchange accounts are responsible for massive loss of battery as well. Exchange users will want to try removing an account and then re-entering the account information. That fix may not work for everyone.

Slow Charging

Some users are also saying that charging the Nexus 7 after installing Android 4.2 is now a long and arduous process. We heard from a few owners who stated that it now takes quite awhile to charge the Nexus 7 after the update, much longer than it took with Android 4.1 Jelly Bean.

Personal Experience

As a Nexus 7 owner myself, I can say that I haven’t seen any of these bugs occur on my device other than the Bluetooth connectivity issues. I’ve tried replicating every single one and the only one I’ve been able to reproduce is the Bluetooth issue where the device can’t keep a stable connection. It also doesn’t sound top notch.

Applications work well on my Nexus 7 and my battery life is as good as it ever was. Charging it doesn’t seem slow whatsoever and it has not randomly rebooted itself.

As with any software update, there bound to be people who have difference experiences based on not only their usage of the phone but their setup – meaning apps, rooting, etc. For the record, my Nexus 7 has not been rooted and is running stock Android 4.2 Jelly Bean.

What’s Next?

Just because I’m not having major issues doesn’t mean that people aren’t. It’s clear that there are enough Nexus users out there experiencing issues that it’s now crucial for Google to update these phones with Android 4.2.1.

When that update will arrive is unknown but we imagine that it could be soon given the outpouring of complaints from owners of not only the older Nexus devices but the newer ones as well.
