Andrey Kormiltsev, the country manager at HTC Russia, has tweeted that the offical OTA rollout of Android 4.2.2 for HTC One users will begin in mid-June. This update has been requested by HTC One users for quite sometime as the release was made available by Google in early February of 2013. This update should bring Sense 5.0 tweaks to the device as well as some of the updates that Google implemented with Android 4.2.2. This includes updated notifications and the introduction of lock screen widgets.
If you’d rather not wait until mid-June to update your HTC One, a leaked ROM for Android 4.2.2 has been available to HTC One users for quite some time now. Installing this update will take a bit more time and skill than the official OTA update will, but it’s worth a shot if you know what you’re doing. The leaked update can be downloaded via the XDA-Developers website.
