In reply to a user's question on Facebook, HTC confirmed that the phone manufacturer will release Android 4.0 Ice Cream Sandwich on confirmed devices by the end of August.

"Yes, the Thunderbolt is still set to receive ICS [Ice Cream Sandwich, released in 2011]. We're still planning to finish updates for all announced devices by the end of August. Thanks for remaining so patient!" HTC said.

Updates for HTC devices are not widespread.

4.0.4 Ice Cream Sandwich arrived on the HTC One X August 10, allowing users to map menu function to the lower-right 'recent app' key; ICS also offers One X users an improved browsing experience through a dedicated tab switching button, along with features including white balance and "continuous autofocus".

The HTC Incredible S recently updated to Android 4.0.4 Ice Cream Sandwich. HTC has not confirmed whether the Desire HD will get Ice Cream Sandwich, after reports that the device was getting an update and then more reports that it might get an update after all.

It seems HTC is updating recent devices: the HTC One X is the high-end device in the One trio of smartphones. With many devices not getting an update, some consumers may feel cheated.

The update is a 250MB download, and users should receive a notification when it arrives on devices. Heading to Software Update in the Settings menu will allow users to manually update.

Other manufacturers, including Samsung, are reportedly testing updates for their devices. Samsung is testing the Galaxy S2 and S3, with the former sounding less certain (probably due to older hardware). Some have questioned the timing of manufacturers' Ice Cream Sandwich updates. This version of Android was released in 2011, and Android 4.1 Jelly Bean will be released in 2012, but 4.0 ICS and 4.1 Jelly Bean remain second and third in popularity behind Android 2.3 Gingerbread. Manufacturer updates are a consistent issue on Android which Google is struggling to rectify.

Users also have the option to download Ice Cream Sandwich or Jelly Bean manually, even if the update for a device is not supported by the company.
