Once again thanks to @LlabTooFeR, we now understand that HTC has begun rolling out the Android 4.3 update to HTC One devices earlier today. Above is the screenshot of the changes expected after the Android 4.3 software update. 2 of the major upgrade include the improvements in color contrast when you snapshot during low light environments as well as the ability to include soundtracks to video highlights.
For now, we’re still under the rocks on when the Android 4.3 update will be rolled out for the rest of the world. In case you do not know, HTC has confirmed that the Android 4.3 update will be hitting the HTC One Developers Edition by month end for the Canadian customers – but it seems like U.S. customers will have to wait a little bit longer this time round…
