Android 4.2.2 is reportedly rolling out for the HTC One, but before HTC fans everywhere rejoice, there is one caveat - it's for the dual-SIM version. Still, the rollout means that Android 4.2.2 for the normal single-SIM HTC One isn't far off.

As of now, it seems that dual-SIM HTC Ones in Russia and China are receiving an over-the-air (OTA) upgrade to Android 4.2.2. Screenshots show the update to weigh in at 175MB, so you'll want to have the HTC One charged up and tethered to a Wi-Fi network.

On top of bumping up the Android firmware to the latest version, the changelog states that the upgrade includes enhancements to the Launcher Bar, a new lock screen style with widgets, better Home button behavior, a new quick settings panel that gives users easy access to 12 default settings. The usual bug and security fixes apply as well as a boost to the camera and galleries. 

For all those with a single-SIM HTC One, Android 4.2.2 is not far off. According to one well-respected HTC insider, it could land by the end of the day.

The news comes after HTC One owners' hopes everywhere were raised (and subsequently) dashed a couple weeks ago when the promised Android 4.2.2 update never rolled out. Instead, it seemed that HTC had pulled Android 4.2.2 back for some tweaking, leading many to believe the upgrade would not be pushed out until sometime in July. If the new dual-SIM HTC One Android 4.2.2 software is any indication, it looks HTC One owners will get their taste of the latest version of Android sooner rather than later.
