The Samsung Galaxy S4 release date might have to be pushed back due to production issues with the device's display.
The new Samsung flagship handset is rumored to feature a 5-inch 1080p Super AMOLED HD panel with 441ppi pixel density.
However, a new report out of Korea states that Samsung is struggling to mass produce these displays because of the evaporation process technology that is normally used for screens.
The company is currently trying to obtain advanced LITI technology from 3M that allows OLED material to be more smoothly printed on glass.
Those with knowledge of Samsung's manufacturing process have stated that the company is having difficulty producing these displays due to issues with blue-colored materials.
Samsung is expected to introduce these new displays at this year's Consumer Electronics Show.
The Samsung Galaxy S4 specs will include a quad-core 2.0GHz Exynos 5450 chipset.
A Korean source has reported that this will be the processor featured in the new smartphone when it launches in 2013.
This chipset will be faster than the one found in the Nexus 10 and will be made on a 28nm process.
This quad-core Exynos 5450 chipset that clocks in at 2.0GHz surfaced in earlier reports that were filled with specification information for the Galaxy S4.
The fact that it keeps popping up is a good indication that this will be the processor that makes its way to the handset.
Another Samsung Galaxy S4 specs leak revealed that the new device will feature a 13-megapixel camera.
This information derived from a document that surfaced on the internet this week.
A higher amount of megapixels will make it more challenging for Samsung to have the handset perform well in low light conditions, since pixels get smaller and noise gets in easier in those conditions.
This 13-megapixel sensor was originally planned for the Galaxy S3 and second-generation Galaxy Note, but when the time came to release the two devices, Samsung chose to stick with an 8-megapixel sensor for efficiency .
A 13-megapixel shooter would be capable of capturing images with 4208 x 3120 resolution. This camera would require more processing power and extra RAM if Samsung were to include it on the fourth-generation Galaxy S.
