Verizon Wireless has confirmed to PhoneNews.com that the HTC Thunderbolt upgrade to Android 2.3 “Gingerbread” has been pulled, due to bugs with the voicemail notification components of the firmware.
The Thunderbolt was Verizon’s first 4G LTE phone, and has suffered several issues, as well as being one of the last LTE devices to be upgraded to Android 2.3. HTC announced last month that the device would be officially upgraded to Android 2.3, by the end of September. HTC made good on that timeframe, only to have the Software Update function report no new update available days later. Several Gingerbread upgrades did leak out for Thunderbolt, PhoneNews.com tested most of the updates and found issues with each of them.
The update specifically affects customers not being notified when a new voicemail arrives. The only current workaround is to periodically dial *86 and check for new voicemail messages manually.
Android 2.3 delivers significant performance and user interface improvements to Android devices, and is the first major release of Android that fully incorporates support for LTE. Google worked with their partners to integrate LTE code from Android 2.3 into Android 2.2 “Froyo”, in order to ensure the devices would launch before the official release of Android 2.3.
Verizon Technical Support has been confirmed to be offering warranty replacements for users that did upgrade while the Android 2.3 update was available from HTC’s upgrade server. Verizon and HTC do not have a timeframe for re-releasing the Android 2.3 upgrade, but did inform PhoneNews.com that they are working to resolve the issue, and anticipate that the update will be available soon.
Verizon also did ask us to notify owners that the software update will be automatically notified and available for all HTC Thunderbolt owners, regardless of if they were running Android 2.2 or Android 2.3 releases.
