Samsung shared, “The software update for Samsung Galaxy S4 Active is temporarily on hold while AT&T and Samsung look into potential improvements.” In such a case, it is most probably due to the fact that there are some bugs in the firmware update which would not bode the Galaxy S4 Active well after installation, where a select bunch of users have alerady reported that they have run into Wi-Fi connectivity issues after the update.
It remains to be seen when the Android 4.4.2 KitKat update will continue down the road, but hopefully AT&T and Samsung will be able to fix this mess sooner rather than later. For those who have already applied the update, how was your experience?
