The T-Mobile branded HTC One is receiving an OTA software update to version 1.27.531.11. Coming in at a whopping 247MB, the update is said to improve software stability and LTE and cell reception. It also includes some processor enhancements, which will hopefully improve battery life and allow the phone to run even more smoothly.
Interestingly, T-Mobile is offering this update not only through the traditional OTA method, but also through HTC’s website, where users can download the update and sideload it onto their devices. T-Mobile also says that it will only deliver the update through August 9; most likely it will still be available from HTC after this date.
As always, if you’re rooted, accept this OTA at your own risk. Developers are likely to release an updated rooted version of most custom ROMs very soon, so it’s probably best to wait until this is available for your particular setup. If you’re running stock, though, be sure to let us know if you notice any additional improvements and enhancements, along with any new bugs.[T-Mobile via Android Community]
