The K850 will be the first Sony Ericsson phone released outside of NTT DoCoMo to support microSD and microSDHC along with Sony's traditional M2. It also introduces the usage of three touch-sensitive softkeys right under the display and a new form of navigation button, omitting the classic joystick introduced with the Ericsson T68. The camera interface has been revamped to resemble the format of cybershot digital cameras. According to the manufacturer the UMTS talk time has been significantly increased to 3 hrs 30 min over its predecessor, the K800 and K810.
