A Korea Times report has hinted that we would be seeing the Samsung Galaxy S IV introduced at the upcoming Mobile World Congress in February 2013, which will be here before we know it. Earlier reports have mentioned that we would be seeing the S IV at MWC as well. The Korea Times did not mention a launch date for the Galaxy S IV, but I would imagine that the device would be unveiled at Mobile World Congress 2013 and the released later in the year around the same time the Galaxy S III launched. Possibly even a little earlier.
Keep in mind that none of this is Samsung-official, these are just rumors, at least for now. Albeit, I think it might be safe to say that we’ll be seeing the Galaxy S IV at the Mobile World Congress. The number of reports pointing towards MWC 2013 for the Galaxy S IV unveiling is considerably large.
In other news, the Korea Times also recently mentioned a Galaxy Note III in the works with a 6.3-inch display, a 2GHz CPU, 3GB of RAM and over 100GB of on-board storage.
Hopefully we’ll be hearing word from Samsung regarding this in the coming weeks
