HTC is trying their best to roll the updates out on their devices, and while HTC One users are waiting for their Android 4.3, Jason Mackenzie addressed when the HTC EVO 4G LTE is getting its Android 4.3. As you can see from his tweet, he addresses when the update is coming as clear as can be, so if you are an EVO user that has not rooted your device, expect that update by the end of the year. No word on the HTC One X and One S, but I am sure if the Sprint variant is going to receive the update, the other two will as well. It just might take a little bit longer.
