Sony has all but confirmed that its midrange Xperia T, Xperia TX, and Xperia V handsets will not be receiving an Android 4.4 KitKat upgrade. All three devices will remain on the latest version of Jelly Bean… at least officially.

OnePlus has rolled out another software update this week, addressing a number of major bugs that were introduced to the One with its last release less than two weeks ago. In addition to fixing the frustrating battery drain problem, it includes a fix for touchscreen problems, a new radio image, and more.

Moto X owners in the U.K. are finally set to receive the handset’s long-awaited Android 4.4.4 KitKat update. Motorola’s latest release delivers the most recent security fixes from Google, improved camera performance, and a new dialer app.

Tesla Model S owners will soon be able to use an iPhone or Android-powered smartphone to start their car when they’ve forgotten their keyfob. The new feature will be introduced with an update to Tesla’s in-car operating system that’s currently in beta testing ahead of its public rollout.

The latest software update for the OnePlus One has significantly reduced the handset’s battery life for a large number of users. CyanogenMod, which is responsible for the One’s pre-installed software, says issues with the proximity sensor and power management are to blame, and it is already working to roll out a fix.
