HTC shelved plans to upgrade the Desire HD to Android 4.0 after extensive testing concluded that the update might not provide the best customer experience on the product.
Earlier in May, HTC updated the schedule of devices that would be getting the Android 4.0 update, which stated that the Desire HD will be getting the Android 4.0 update between July and August. We've reached out to HTC Singapore and have confirmed that the Desire HD will stick with Android 2.3 Gingerbread. Here's the footnote from HTC's official blog:
HTC - "After extensive testing, we’ve determined that the current version of HTC Sense with Android provides customers with the best experience on the HTC Desire HD. When we consider new versions of software, we weigh a number of factors, but ultimately the customer experience on the product is the deciding factor. We apologize for any confusion this change may have caused our customer."
In July 2011, HTC suffered backlash from customers after it announced that it won't bring the Gingerbread update to the Desire due to a lack of memory. Within the day itself, HTC retracted its statement and promised the Gingerbread update for the phone. It remains to be seen if history will repeat itself with the HTC Desire HD.
The Taiwanese company is the first Android vendor to officially confirm that the Android 4.1 Jelly Bean update would be coming to the One X, One XL and One S.
