Fellow brothers and sisters of the HTC One S. This should ignite a fire underneath those butts of yours to root that device of ours. Seems that HTC has released a statement to Unwired that confirms that the HTC One S will remain at Android 4.2. No update for Android 4.2.2, nor Sense 5 coming around the bend.
We can confirm that the HTC One S will not receive further Android OS updates and will remain on the current version of Android and HTC Sense. We realize this news will be met with disappointment by some, but our customers should feel confident that we have designed the HTC One S to be optimized with our amazing camera and audio experiences.
So if want to get to Android 4.2.2, you are going to have to take the time and root the phone. Feel free to hit me up with any questions if you decide to do so.
