Asus had already rolled out KitKat updates on its ZenFone series. Some users had already mentioned about the update on the ZenFone 4 a few days back. The KitKat update has now been rolled out on Asus Zenfone 4, Zenfone 5 and Zenfone 6.

It would be wise to wait for few more days to check if there are no issues. Usually there should not be any issues however in case you don’t want to take the risk better avoid updating for few days. Asus Zenfone users might have already got the notification regarding the update. In case you did not get the notification just go to settings, about phone and in software options tap the software update button.

This is not the first time Asus has rolled out updates for their Zenfone model, they had provided few updates before for some minor software issues / bug fixes etc, but this one is new, it replaces the current Android 4.3 with Android 4.4.

Before the update make sure the battery % is over 75 and if possible take a backup of your data.

Asus Zenfone kitkat update rolled out

If you own any of the Zenfone models and have upgraded to the latest ROM Android 4.4, do leave your feedback or any issues you might have encountered.

  1. Got my zenfone 5 today, as soon as i started the phone it suggested me for software update, when finished the update tried connecting it to wifi and the bl***y phone does not work tried different networks to connect but all effort went in vain. I request a suggestion regarding this issue as early as possible other wise i would be forced to return this “LEMON” piece of thing.

    1. Ignore the Wi-Fi setup and try doing a factory reset, in most cases it will fix the issue, try it and see. If still an issue you can always get a replacement.

  2. I have got the msg to update my asus zenfone 4 of file 582 MB. i update on wifi. After downloading all files it failed and msg shown returned to original configuration then the system update file of 582MB again started. I did not receive any update to android kitkat.

  3. From the day I bought the phone, it always takes more than 10 min whenever I restarts it. Recently, when I upgraded to kitkat, from then I never been able to transfer files using wifi i.e. using apps like Shareit! or Zapya and Flash Transfer. And now today at afternoon, when I updated the phone again with another update available, I expected the fixes of my problems but, what the hell? My phone is not even starting!

    What should I do?
