The S Voice was described as " not optimised " and " more rigid than Siri " with its poor voice @-@ recognition accuracy , with instances when it would not respond at all . Another usage problem was a microphone malfunction that resulted in difficulty communicating during a call . Reviewers have noted the somewhat abrupt auto @-@ adjustment of display brightness , which tends to under @-@ illuminate the screen ; however , it has twice the battery life compared to the HTC handset , achieved partly through the dim display . Others say the numerous pre @-@ installed apps make the S III feel " bloated " .
