Samsung Galaxy S II HD LTE is an S II on steroids: 4.65-inch display, pixel density at whopping 316ppi60
We’d usually leave the dramatic phrasing for something of the caliber of the iPhone 5, but this here Samsung Galaxy S II HD LTE is pretty much everything an Android aficionado would dream of - except it’s currently landing only in Korea. Hopefully, that doesn’t mean that in a certain time in the future, we won’t see it land in the States.
With this bright hope in mind, we’re looking at the S II HD LTE, where HD stands for the 720 x 1280 pixel resolution on the 4.65-inch Super AMOLED Plus display and LTE stands... well, for LTE for Korea. Yup, that’s 316ppi of pixel density, blowing away the original S II out of the water with its 218ppi.
Update: But there seems to be a little catch - the display most probably uses PenTile technology so each pixel actually has only two instead of three subpixels. That 316ppi is then not comparable on the same basis with what other non-PenTile screens have. We've covered the issue of future HD Super AMOLED Plus displays in more detail here, but to put it shortly - using a subpixel count we'd arrive at a pixel density number of 216ppi, which is on par with the S II, so it really depends on the way one approaches the issue.
Under the hood of the S II HD LTE roars a 1.5GHz dual-core processor and the list of features continues with NFC, an 8-megapixel camera recording video at 1080p and a 1,850mAh battery.
The rest is pretty standard Galaxy S II looks with a slightly elongated home button on the bottom, and nearly the same slim profile with 0.37” (9.5 mm) of thickness, a hair thicker than the 0.33” (8.49mm) body of the original S II.
Along with the S II HD LTE, Samsung also unveiled the nearly identical Korea-bound Samsung Galaxy S II LTE. The difference between the two is mainly in the screen as the S II LTE has a smaller, 4.5-inch, and less dense, WVGA, display, but it's of the Super AMOLED Plus variety.
