According to Business Korea, citing a partner of Samsung will be the manufacturer to bet on 4K resolution for the Galaxy Note 8, or whatever the device now for the name.
Samsung is said to once again use the 1440p for the Galaxy S series but take the step up to 4K with the next Note.
the Reason is said to be virtual reality, and a new Gear VR headset.
Higher resolution than 1440p should not be needed on the mobiles, but virtual reality has the great advantage of more pixels.
If the rumor is true will be the Note 8 is not the first phone with 4K, then Sony released the Xperia Z5 Premium already in last autumn.
Z5 Premium uses only 4K of the particular image content, and renders the interface in 1080p.
