Ice Universe previously stated that the Samsung Galaxy S23 Ultra's design will essentially not change and that the differences in size would just be millimeter-sized. More specific information, including as the screen size, resolution, and dimensions for the complete S23 series, has now been revealed by the leaker.
In short, all three versions will have slightly larger heights and widths while maintaining the same display diagonal and resolution. Although the weight has not been specified, it should largely be the same as on this year's S-series.
Ice's claim makes it doubtful that the Galaxy S23 and S23+ displays would finally return to QHD+ resolution (like they did in the S20 generation). At the very least, will they transition to LTPO panels? That much is still unknown to us.
With regard to specifications, the Galaxy S23 Ultra is said to contain a new 200MP camera, a new, larger FP reader, the same 5,000mAh battery size (but with a modified 45W charger to fill it up faster), and the same 10x periscope. The rumours assert so, and they assert the same thing for the S23 and 23+ tele cameras.
