Samsung has plans to announce a new Android 4.0 Ice Cream Sandwich-powered smartphone at the annual Mobile World Congress trade show in Barcelona later this month. An image of the unknown device was published on Thursday by industry insider Eldar Murtazin, though no additional details were provided. The handset looks very similar to Samsung’s Galaxy S II handset, but the buttons beneath the display have clearly been updated to support Android 4.0. The phone is likely not the upcoming flagship Galaxy S III, however, as Samsung recently stated that its Galaxy S II successor would not be announced at MWC. The phone is also likely not the rumored Galaxy S II Plus according to benchmark test results that surfaced recently, as it is believed to be running an older version of Android — though that certainly may have changed. Whatever the device may be, we’ll be reporting live when Samsung finally unveils the sleek smartphone during its press conference in Barcelona later this month.
