Samsung has offered two lines of ruggedized smartphones, one of which remains.
Galaxy Xcover
Starting in 2011, Samsung launched the ruggedized Galaxy Xcover line, which has greater dust and water resistance than other Samsung smartphones. Screen sizes range from 5" to 6.6" and rear cameras from 16 to 50MP.
Galaxy Active
Released in 2013, the Galaxy S4 Active was also a ruggedized model but lasted only until 2017. Screen sizes were 5.1" to 5.8". Active models were considered more durable than Xcover, but Xcover models were upgraded after the Active line was discontinued. See
