Motorola is skipping Android KitKat 4.4.3 on Droid Ultra, Maxx and Mini smartphones for Android 4.4.4 to take into account an OpenSSL vulnerability. David Schuster took to Google+ to announce that the manufacturer cancelled the release of Android 4.4.3, which consumers have been patiently waiting for, to work on testing and readying the latest version of KitKat. The bad news is the wait will be prolonged, but there's light at the end of the tunnel.
"Sorry for the delay in giving an update on the 4.4.3 upgrades but I had to wait unit Google announced KitKat 4.4.4 today (I am bound by a NDA). A significant security vulnerability was discovered by OpenSSL (https://www.openssl.org/news/secadv_20140605.txt) and is fixed in KitKat 4.4.4. We had to wait until KitKat 4.4.4 became available. Consequently, all of our 4.4.3 upgrades that were in carrier labs worldwide (including the 2013 Droid's) had to be respun, tested and resubmitted again. This was a significant unplanned effort that we had to undertake. We should be re-entering labs next week and hopefully getting TA (technical approval) in 3 to 5 weeks later depending on the carrier."
When can we all expect to see the update rolled out to affected hardware? kitKat 4.4.4 is currently looking to be technically approved within 5 weeks, depending on mobile operator. Android 4.4.4 has just started rolling out for Nexus hardware. We'll update you all once we have confirmation the update is rolling out to the Motorola Droid Ultra, Maxx and Mini.
