For me, anything more than 300dpi is just an excess. If the cost of putting 1080p is negligible, then I don't mind at all. But if it cost a lot, then I prefer either a cheaper 720p alternative or put the extra money for bigger battery/storage/wacom stylus/etc

Btw, is there a thread discussing that new Huawei k3v2 processor/soc?

I could see that kind of dpi becoming useful for a parallax barrier 3D screen. A 459dpi screen would result in a 230dpi image for each eye.

True, but how relevant is a 3D screen on a phone? The only thing where a 3D screen currently really adds anything to the experience is in movies and 3D games and how often will you be playing either on a phone?

So 4.8 inch isn't too big?

Might as well go all the way to the Note size.

It's not so much the screen as the device size. If they can cut down on the bezel, a phone with a 4.8" screen could easily be smaller than current ones that sport a 4.3" screen. The lack of capacitive buttons alone could easily make up an extra ~0.5" of screen space.

first data up on samsungs site for the 5250.

Strangely, although its been comfimed elsewhere that this chip is using T604, DX compliance is glaringly missing from the graphics compliance list. Would appear samsung is not targetting this dual A15 soc at windows ?

Maybe a nod to the Galaxy s3:p (*fingers crossed*)

About the silly rumours of 4.8inch 1080p AMOLED plus screens...ive done some research into this and i can tell you with some certainty...thats bollocks!:rolleyes:

There is a reason we don't see any RGB or AMOLED plus screens @ WVGA resolution or greater below 4.3inch (GS2..LUMIA 900-both Sammy) because its impossible with current technology...even for the rest of 2012.
OLED just doesn't allow as high DPI as LCD counterparts.....you notice that the worlds top AMOLED manufacturer Sammy (they produce 98% of the worlds supply-including Nokia) has to increase screen sizes AND use the space/energy saving pentile matrix (uses 2 subpixels instead of 3= 30% less subpixels) to go to higher resolutions....so that means 4.65 inch pentile 720P screens... (galaxy nexus) or 5.3inch 1280 x 800 pentile (galaxy note ) both at end of 2011...

If the rumours are true and we do get a 4.8inch..the best we can hope for is the vastly superior RGB 'plus' AMOLED at 720p....even using pentile current technology does not allow greater than 330 dpi AMOLED screens..period.:oops:

And just to note i would be over the bloody moon to get that screen with some gorrila glass 2!!:p

A demonstration of sub pixels..Pentile v RGB...

Still no integrated baseband in Exynos 5?
Click to expand...

I'm pretty sure Samsung said they'd include LTE support directly on the chip this year. I don't think they really liked having to use Qualcomm S3 chips in their phones to get LTE support in their flagship devices. And we know that Exynos is technically capable of supporting LTE, since the Galaxy Tab 7.7 has it, so it must be a space issue.

I think Samsung knew for a while that it wouldn't have a DX-compliant SoC until the Exynos 5450, which uses the T658 GPU, and isn't scheduled to come out until 2013 or so. But that doesn't really matter that much, as 2013 is going to be the big year for Windows 8, not 2012.

Actually, the news I've seen say that Samsung will use their own baseband units for their handhelds (instead of purchasing from qualcomm).

They already use their own base bands for some of their CDMA/LTE phones like the Droid Charge (CMC220) and Galaxy Nexus (CMC221) according to AnandTech.

Agree with all the above, and anyway, whoever believed the 1080p rumours is just naive.

Second of all, the screen will most probably be this one:

Code: 
#ifdef CONFIG_FB_S5P_S6E8AA0
/* for Geminus based on MIPI-DSI interface */
static struct s3cfb_lcd s6e8aa0 = {
	.name = "s6e8aa0",
	.width = 720,
	.height = 1280,
	.p_width = 60,		/* 59.76 mm */
	.p_height = 106,	/* 106.24 mm */
	.bpp = 24,
4.8" 720p screen. Taken from mach-midas.c from the latest kernel source drop from Samsung.

Nice find!...If thats RGB & gorilla glass 2 & improved DNIe.. i will be salivating:D

I'm really hoping that's an RGB panel. The current panel on the Galaxy Nexus is great and all, but you're still chopping off 33% of the pixels out of the display with a 2-pixel RGBG arrangement, especially in an OS that has a lot of lines in it as part of it's UI now in ICS.
 
Pentile does have advantages..as outlined above..better longevity/power consumption/33% more space.

The reason why people call it a 'bug screen' and generally hate it compared to RBG??

It can be best summed up with this;:oops:

EDIT; As DAGAMER pointed out, the PPI of both screens are not identical and favour the ONE X's RGB..making it slightly off accurate..but the effect is the same non the less.

ONE X 1280 X 720 @ 4.7 = 312.47 PPI
ONE S 960 X 540 @ 4.3 = 256.15 PPI

If we get an advanced RGB AMOLED panel matching the ONE X's pixel density then we are going to be in for a treat....batterylife will suck though ;(

It should be stated that the DPI for the One S and One X are not the same, so this isn't as true as it might seem.
