Concerns were initially raised via the xda-developers forum, after users suggested that the One X’s Sense 4.0 UI has multitasking behaviours that are vastly different to those of other Android Ice Cream Sandwich devices.
The change was initially considered to be a low level UI tweak, however further investigation has pointed out the differences are at memory and task management level. Tech site Engadget approached HTC on the issue, who replied with the following statement:
“HTC is aware of some questions in the enthusiast community about how the HTC One X handles multitasking and memory management for background apps. We value the community’s input and are always looking for ways to enhance customers’ experience with our devices. That said, multitasking is operating normally according to our custom memory management specifications which balance core ICS features with a consistent HTC Sense experience.”
So it appears that that the multitasking and memory management differences have been implemented by the manufacturer in order to ‘enhance customer experience’, and tie in with suggestions that the bespoke system is at least partly responsible for the One X’s impressive battery life capabilities.
