Korea's Naver.com reports Samsung (SSNLF) plans to launch the Galaxy S5 Prime, a version of its flagship phone that features a 2K (2560x1440) display, in mid-June via local carriers SK Telecom, KT, and LG U+. The phone will reportedly cost just $50-$60 more than the regular S5.
There were reports the S5 would sport a 2K display prior to its launch. Samsung instead went with the 1080p resolution used for the S4, albeit with an improved OLED panel that has received good reviews.
Samsung stated last November it plans to launch phones with 2K displays in 2014, and phones with 4K displays in 2015. Universal Display (OLED -0.1%) wouldn't mind seeing that happen, given OLED panels with higher resolutions require more OLED materials.
Naver's report doesn't state whether the S5 Prime will feature a metal case, as has been previously rumored. Samsung has received its share of criticism for sticking with plastic cases for its high-end phones, and the company recently replaced its mobile design chief.
Apple, a fan of using aluminum cases (the plastic 5C excepted), is expected to launch 4.7" and 5.5" iPhones in 2H14.
