The HTC One remains my favorite smartphone ever and to make it even better T-Mobile started rolling out the Android 4.3 update yesterday. After installing the 560.18 MB update, I have a more functional device yet I am still looking for the Sense 5.5 enhancements.
This update bumps the core OS to Android 4.3 while also enhancing Sense 5 a bit. You will find Android 4.3 and Sense 5 features such as:
OpenGL ES 3.0 for better graphics rendering
New Quick Controls button in upper right corner
Bluetooth Low Energy support (my Fitbit still won't connect)
Daydream standby functionality
New Video Highlights themes
Ability to add your own music to Video Highlights
Improvements in camera for low-light environments
Unlocked, Sprint, and AT&T HTC One devices already received the update with Verizon HTC Ones, they launched with 4.2 instead of 4.1, scheduled to receive the update before the end of October.
The cool new features of Sense 5.5 we saw in the HTC One Max are not in this update, but we should see them come to the HTC One in a future update. Sense 5.5 improvements include addition of Google+ to BlinkFeed, option to completely disable BlinkFeed, offline BlinkFeed article viewing, and better usability of BlinkFeed with a side sliding menu.
With this update in hand, I am returning my Galaxy Note 3 since the RF reception is better, the device is much better designed and fits better in my pocket, and Exchange works for me on the HTC One.
