HTC and Motorola are first out of the gate with promises to upgrade their phones to Android 4.4 KitKat, the latest version of Google's operating system.
HTC's vows are the boldest of the bunch. The phone maker told Engadget that the flagship HTC One will get upgraded to KitKat within 90 days on all U.S. carriers, including AT&T, Sprint, T-Mobile and Verizon Wireless. The unlocked and developer versions will get the upgrade within 30 days.
Unfortunately, HTC's upgrade plans for other phones such as the One Mini and One Max are less clear. HTC told Engadget that it's still working on rollout details for other devices and will have another statement in the near future.
Motorola, meanwhile, hasn't given a time frame for any of its devices, but theGoogle subsidiary does have a handy website for checking upgrade eligibility. According to the site, the Moto X, Droid Ultra, Droid Maxx and Droid Mini will all get upgraded to Android 4.4 Kitkat. The Droid Razr Maxx HD, Droid Razr HD and Droid Razr M have a "Future plan coming soon." All older Motorola phones will remain on Android 4.1.2.
Samsung hasn't given any commitments so far, with the company's U.K. branch telling CNET that it will "announce rollout plans for Android 4.4 in due course."
Sony, which has a strong track record for quick Android upgrades, also hasn't announced any KitKat upgrade plans yet. The company wrote on Twitter that it will announce its plans next week.
LG hasn't commented on its Android upgrade plans.
Of course, users of stock Android phones and tablets can expect prompt upgrades. Google says upgrades for the Nexus 4, Nexus 7 (both 2012 and 2013 models) and Nexus 10 will arrive in the next few weeks. Same goes for Samsung's Google Play Edition Galaxy S4. HTC told Engadget that it will upgrade the Google Play Edition HTC One within 15 days.
The news isn't so sweet for older stock Android devices, with the Samsung Galaxy Nexus falling off the upgrade list. "Galaxy Nexus, which first launched two years ago, falls outside of the 18-month update window when Google and others traditionally update devices," a Google support page says. And if you have any other Android device that's more than 18 months old, you'll need to resort to unofficial tastings of Google's latest Android flavor
