Android 4.4 KitKat will bring many improvements to the three Droids, including a brand new full-screen mode, stronger security, smarter power mode, and color emoji support. There are also several apps and widgets that are being updated, like Motorola Assist, Quick Office, Amazon Kindle, Verizon Mobile Security and Verizon Tones.
Other Verizon Motorola smartphones that will get Android 4.4 KitKat are the Droid Razr HD, Droid Razr HD Maxx, and the Droid Razr M. Verizon didn’t say exactly when these will receive the update, but we have a feeling that it won’t be long now.
