[Samsung Galaxy Nexus] Sjael:
There's a certain size that the blue subpixel needs to be, under which it degrades too fast. The red and (particularly) green subpixel aren't so constrained, which allows PenTile to shine.

What they do is keep the blue subpixel the same size as it would be in an RGB array, thus guaranteeing the longer lifespan, but then shrink the green subpixel. Something like this:

the PenTile matrix allows them to cram more pixels into the same space (hence why the Galaxy Nexus at 4.65" has a significantly (some 140%) higher resolution (1280x720 pentile) than the 4.3" Galaxy SII (800x480 rgb.) despite being only about 7% physically larger.)

The actual science is very complex, but basically the human eye is very good at seeing detail in greens, so they include a lot of green subpixels (Motorola's RGBW pentile screens don't.) Reds are less important, and blues are far less, so most people never notice the PenTile patterning on blues, but can on reds from a short distance away. There are whole other layers of complexity to do with how the eye deals with simple versus complex shapes, and text versus pictures (a common point of discussion,) but that's about the root of it.

Samsung's next-gen OLED printing tech would probably easily be able to print a 1080p RGB-stripe OLED in the same space - however it's just not mature enough to produce good yields yet. It's not really that Samsung is trying to keep costs down by using the current screens, it's that the costs would be far too high with better ones. No one will buy a top-end phone now if it doesn't have a 720p screen, and Samsung can't afford to produce pocketable 720p RGB-stripe panels, so the only answer is these ~4.7" 720p pentile screens - after all, only a couple of percent of buyers will ever notice it anyway. :)

Disclaimer: I'm not an expert by any means, but this is what I've gleaned from a considerable amount of research and reasoning (and even discussion with the CEO of Nuovoyance, who developed PenTile.)
[Samsung Galaxy Nexus] Step666:
Brightness 'issues' (and I use the term loosely as it's all subjective) will be down to the fact it's AMOLED.

But the graininess must be due to the sub-pixel matrix. I can't think of reason why an RGB AMOLED panel would be 'grainy' if a similar RGB LCD panel is not.

edit:

Do you have anything to back that up?
[Samsung Galaxy Nexus] Nevod:
The grain is exactly due to it being AMOLED and an not good enough manufacturing process. Even semiconductor LEDs in have some parameter deviations especially at lower brightnesses, and tiny mask-printed AMOLED has significantly higher deviations leading to 'grain'.
[Samsung Galaxy Nexus] kenerson:
But if the blue subpixels in both RGB and the Pentile are of the same size, and green and red are of less issue, then what makes Pentile's lifespan longer or its blue subpixel's lifespan longer?

Does it have to do with the chance that they will be used less often?
[Samsung Galaxy Nexus] Sjael:
What would you like me to back up?

It's well documented that blue OLEDs degrade much faster than red and green ones so they are made to a certain size to guarantee they last. We can logically assume that since Samsung had to move from 4" to the then-unpopular 4.3" (actually 4.25") form factor to accomodate SAMOLED+ where all subpixels are effectively same-sized (and they continue to produce high-end panels of about the same sub-pixel density,) that is as small as they can print blue OLEDs. If that's the smallest size they can make a blue subpixel with enough longevity, that size would carry over to any PenTile design also. There's a photo out every 5 seconds showing PenTile screens under a microscope so we know the green and red are smaller. The rest of my post was just math. Hope that helped. :)

The blue subpixels are the same minimum size, but the (unimportantly) red and (importantly) green are smaller. This lets them fit more pixels into the same space. The 'improved longevity' of PenTile is compared to an RGB stripe of the same pixel density. If you put a full RGB pixel in the same space as a RGBG pixel, the blue subpixel in that RGB pixel will be much smaller, and won't hold up as long.
[Samsung Galaxy Nexus] kenerson:
I think I understand this observation... So assuming that both blue subpixels of Pentile and RGB are of the same size occupying the same space, the only difference will be the pixel density (with Pentile higher, and RGB lower) but both their lifespan would be equal. Am I right here?
[Samsung Galaxy Nexus] albundy2010:
I have seen the brightness issue being blamed on amoled quite a few times in this thread. That is just blatantly false.

There are plenty of amoled screens from various generations of the tech that are far brighter.

The gnex is rated at 204 nits over at anand. The nexus one is higher. The displays in the original galaxy s is rated higher. Much higher. The galaxy sII is higher and so on.
[Samsung Galaxy Nexus] Teqonix:
Very interesting chart - I was thinking I had seen other AMOLED phones with screens that looked way brighter. Sigh.

Honestly, with these pentile matrices and low lifespan of the OLED pixels, I think I'll stick with LCD phones in the future (especially assuming the Nexus program is being opened to multiple manufacturers).
[Samsung Galaxy Nexus] Sjael:
Yup. :D
[Samsung Galaxy Nexus] M0D1441:
After using a Samsung Galaxy S II Skyrocket for about 6-7 months and now owning a Galaxy Nexus I have it admit

I much prefer the Galaxy Nexus screen as it is the best screen I have ever used on a phone, doesn't matter if its pentile and what not, its amazing, I mean, 1280x720, darn, that's what my 36" TV is! This might sound odd but I even prefer pentile over RGB, because I've had a more flawless experience with it, dating back to my Nexus S, (which I prefer greatly over my skyrocket screen). And I'm a perfectionist, so not being bothered by it might be a real good point not to hate on pentile :P

If you're asking about how to do it manually:

Use a file explorer app with root privileges like Root Explorer and navigate to /system/buil.prop, long-press on it and choose open in text editor

Search for a line that reads:

ro.sf.lcd_density=320

Change that value to what you wish, don't go too low or you might end up with a bootloop

I just got my Flyer from Cowboom yesterday, and it looked brand new. However, a lot of times the tablet will start pulling the lock itself, exiting applications by itself, click on random buttons by itslef, etc. Is this a normal thing to occur? How can I fix it? Should I send it back for a replacement?
[HTC Flyer, EVO View 4G] quails:
Do you really need to ask ? Nope not normal.

Definitely not normal. Try doing a factory reset of the device and see if that it. If it doesn't, I'd return it.

I have a similar problem. I recently bought a used Flyer and it came with the HTC pen. Here's my problem, whenever I use the pen to take notes, sometimes the pen will continue to write even though the tip isn't touching the screen. The tip is close to the screen but doesn't actually touch it. I was wondering if I had a defective pen.
[HTC Flyer, EVO View 4G] j510:
There's too much ink in the pen. No that happens sometimes with new batteries

I had the same problem with mine and I thought the screen digitizer had gone bad. Mine was in a case that had some metal in it and after I took it out I have had no problems at all. Yeah, it sounds stupid but I now have a otterbox case which does not have metal and I have not had any problems. As far as the pen I took the batteries out and put them back in and fixed the pen problem.

I've had to do that with the pen. I found I must remove the battery for about a minute, then reinsert. Less than a minute it doesn't reset.
[HTC Rezound] DrGlitchyPhD:
So I've been alternating between multiple ICS roms and Bamf gb and I just can't stay with Ics. I absolutely love all the ICS roms, but my battery life won't get me through a work day. Even with data off and only sending a few text messages it lasts about 6 hours. I first used the ics firmware and one of the older ics leaks and had horrible battery life. I just tried the newest leak with gb fw and still its horrible. Am I doing something wrong? Why is my battery half of what it was on gb? :(

In short why can't I have good battery life on ICS?
[HTC Rezound] a.mcdear:
In short: because its not done yet, which is why they haven't released it yet.
[HTC Rezound] DrGlitchyPhD:
Why do so many people claim they get the same or equal battery life? With so much fairly polished in it I wish battery life was better.
[HTC Rezound] a.mcdear:
My battery life is just fine on ICS and I have no heat problems either.... but its definitely been very hit or miss.

There are probably a few different hardware revisions out by now, and the various issues are probably affecting only certain phones and not others because of slight differences between them.

If you are one of those people who are having problems, best thing you can do is wait until HTC releases the final ICS build..
[HTC Rezound] speedtigger:
any idea why text messages would cause reboots on ICS ROM's?
[HTC Rezound] dyetheskin:
it shouldn't period. never had that happen. sounds like a bad flash,dirty flash

nsd combination of radios/firmware or a mix. I'd backup, run the latest ruu,clear/reset through bootloader,flash newest amon recovery,wipe everything,flash rom/kernel and firmware patch depending on which you chose. if using new firmware use the 5/2 radios to reduce heat. hopefully you're s-off to do all that

I really like GS3 but.. I miss the "wow" effect..

Well: it is great.. but only "in hardware specs".

When I saw padfone unboxing.. I remembered the "wow" effect.

But I LOVE to use the same device (same SIM, same SD CARD) on a bigger screen!

Yes, I know price is a big problem but.. You buy TWO DEVICES at the same price of GS3 (herein italy we will pay GS3 699€!).

But I am afraid that developers will cook for GS3 and not for padfone..

And it is very important for me to customize ROM..

Sorry, I don't have anything to contribute, judging by its name and its look, looks like Apple has a new target. Seems to be onpar with the HTC One S in term of spec and screen, but with the tablet thing and microSD slot. I really like the Asus color scheme.

http://www.gsmarena.com/asus_padfone-3965.php
[Galaxy S III General] eletro:
Good point there.. normally popular phones would have more developers, and accessories.

and it uses PenTile tech ... much like atrix and sgs3. But its more towards that of atrix (although atrix is not amoled), as its same reso with a bigger screen, but expect to see grainy results.. (i have the atrix .. so can somehow picture how it would look like.)

Hardware wise its on par with sgs3.. but yea .. it might lose out in endurance due to a smaller batt, unless u carry the tablet around with u.

Software wise.. im not sure what it does when place in tablet dock.. but like the atrix's webtop .. u might expect funky software tweaks to achieve that.. and that might hinder developers trying to cook roms or cm9 full compatibility? ;/ (just my guess)
[Galaxy S III General] Kailkti:
Considering its ICS, which is built for both tablets and phones, when plugged into the Tablet it would prolly just enlarge the screen or sum. No need to launch a whole different OS.
[Galaxy S III General] DJ Palmis:
That is the point! If you can you bring tablet with you.. If you can't You just have your mobile with you!

I confess that I did not know Webtop!

Well i think that this will be the future: A mobile phone that is a Personal Computer (when You need it!)!

Problem is marketing: I bet that if Apple sells something similar I'm sure we'd see a lot of people cry for it..

Anyway: The dream is a Tablet like the padfone one for S3.. Maybe that works using Wifi direct..
[Galaxy S III General] Rytkonen:
I need to criticize Asus a little. I have Asus Transformer Prime and I absolutely love it with almost stock ICS and stunning looks (its beautiful, seriously http://www.blogcdn.com/www.engadget.com/media/2012/04/transformer-prime-behind.jpg).

However at the moment I'm not 100% convinced with the Asus software. With the latest firmware there are quite often random reboots and the most annoying "xx has stopped, wait/close"-dialogs, especially when using any other browser than Opera Mobile (which runs like 15fps). The browser loads the page almost to completely, then often just stops and gets stuck for 3-10 seconds. If you try to touch the screen when it is stuck the "Browser has stopped"-dialog pops up. When you click wait it continues like nothing happened.

These are known issues with the latest ICS builds and I really hope Asus gets especially the browser fixed. With 4+1 core Tegra 3 the web browsing should be blazing fast, seriously. I am embarrassed to show my 600 euro tablet to any of my friends when it gets stuck with browsing internet. :D Atm web browsing is nowhere near even the SGS2, which runs like every web page smooth with all the flash content active.

Asus has an employee hanging with Prime users on the XDA forums and they are constantly communicating with users about the issues. This is very positive movement from Asus and is something Id really like to have from Samsung. There are even few (un)official Asus threads there where they announce new updates and so on.

Then Ill give one point towards Samsung about its bootloader policy. Asus has locked bootloaders which can be opened only with Asus official tool which reports the bootloader status straight to mothership. So basically you give up your warranty to Asus if you want to install custom roms.

Why I am blathering like this? This is just an example about situation when the grass always seems to be more green on the other side of the fence. :D In reality, it isnt.

In summary, I love my Prime and I trust Asus that they will get these issues fixed. And also I cant wait to get my pre-ordered SGS3.
[Galaxy S III General] DJ Palmis:
Thank you very much for your infos: I did not know that there is Asus sipport on XDA.

[Galaxy S III General] gasolara2002:
In my opinion you can't go wrong with either device. I say they have their weaknesses and strengths. As far as just specs I honestly say the SGS3 has better specs but the ASUS is not too far behind. The padphone looks way better to the eye. The padphone has a great function factor with the tablet and a cheaper pricepoint. The SGS3 will have alot more development but i do say asus will have enough development also due to the success of their tablets of late. If the tablets gets devs like i predict it will then the phone has got to get devs also in order to keep them working together properly. I say we won't see the potential for any quad core processor until the applications are actually made to utilize quad core processors. I think that will come very soon as they become more common. I say it is up to the individual. I will be honest and say i honestly can't lean to anyone. I would have to see tests and reviews first.
