Just got my 003 Evo!

Returned my 002 Evo to the horrible radioshack and went to bestbuy mobile and bought myself a new Evo.
Things I've noticed at first glance. The epson screen and the battery cover. The screen is noticeably much more vivid and brighter. The matte cover on the back has a great finish and feels like a Nintendo DSi. No more light leakage!!! Woot! And odd but the power button responds much smoother and feels a lot better when pressed down.
Also some info I got from the reps there were that Sprint is going to put out another update to fix the 30 fps limit. Great news and I played around with the black and white demo evo. It has a GLOSSY finish which totally turns the phone off to me, because of finger prints and it looks incredibly ugly in my opinion.
I checked the firmware on my evo and it's still 1.32.651.6! I can still root my phone!
DT10.06.17 is my build date.
This is the Evo I should've received during the launch date. This phone is incredible!
Edit: After playing with the phone today, the speaker is much louder & the call quality is much clearer and louder than my 002.

Yay for you.
I too am still on old version...but wonder how can we get to any new updates if they all locked like new OTA. Hope this only means (yay devs) that we just have to wait a little longer between updates to get new stuff.
That 30fps fix would be nice to see...but store reps lie like rugs. (Oh wait, did I say that outloud?)

I had launch day 002 and had to swap my OTA bricked EVO and IMO the new screen is waaaay better.

The Epson screen is higher quality than the Nova.

I've seen this stated both ways on this message board. I think that it comes down to preference.

There's no way that the Epson screen is brighter than the Nova. Might yield more accurate colors, but out of the thousands of reports, the Nova is much brighter always. Are you sure you have an Epson screen? Not all 003s are Epson (as it's my case). I'll only believe it when I see pictures.

Yes, this statement is correct. However Epson has truer blacks without purlish hints

Epson: Better quality, not as bright.
Nova: Purple tent, brighter.
Or that's how I would put it.

Why are so many people thinking that if its 003 its Epson? I got a build date of Jun 16 and its Novatec. So they know the problem exist and they keep sending phones with Nova. I think there is something else involved in there.

Thank god I'm buddy's with the radio shack guy, he's getting me a new one even though I kinda don't even need one. So he will not update it if I ask him to not update it....I'm just not sure which screen I prefer. I love the Nova screen, I just can't imagine a screen looking much better. If the Epson isn't as bright that kinda sucks, though more accurate colors do sound good...and then there is the issue of the 30fps thing. The hack we have currently works out awesome on my Nova...I wouldn't want massive tearing, however if they do address the bug then it is a moot point.
Buuuut I don't think that they are ever going to. I might just turn down the new one and deal with my slight light leak and very very minor screen lifting. It hasn't gotten any worse in 2 weeks.
Hmm, decisions decisions....

There is that "fix" for screen separation that involves a hair dryer. I've been wanting to try it as people who have done it say it works. Plus people with N1's said they had the same problem and the hair dryer "fix" does the trick.

A quick way to tell which screen you have is with the "Power Control Widget" If you cycle through the brightness settings and it instantly changes you have a Epson, if it fades in and out for each change you have a Nova. At least that's what I have been reading in the forums.

Instant brightness change. I also compared it to my GF's launch day 002 and they are hugely different in screen colour/sharpness.

Hm true it's not as bright as the nova only difference is in direct sunlight, BUT the colors are much more vivid and yes I do have a epson. Tried the power control widget and my screen doesn't fade like it use to, it changes the difference in a split second. My build date for the phone is not bad either. DT10.06.17.

Screen differences outlined. Why don't you fade you stupid brightness control!

OK so I have in front of me a novatec and epson unit.
I need to choose which one to keep and it is killin' me, for several reasons.
Off the bat. Pro's of both.
Novatec:
Looks better/more vibrant.
Brighter.
Changing brightness always fades in and out. (Noticeable from power control, screen timeout, and brightness control in the settings menu)
Epson:
More realistic.
White's and black's look better.
Problems. They both have light leakage (same amount).
However, the novatec has a stuck pixel which is why I got a replacement, also, though it looks better the coloration is very slightly off (strange, almost pinkish hue on white's).
Epson sometimes shows horizontal lines upon close inspection (especially on grays) where the novatec doesnt. Also looks slightly washed out..
The last problem that is really bothering me.. It doesn't fade in/out lol!
I know it sounds stupid, but why would a different LCD change something like that? Which is clearly software.
Is there any way to bring that back?
It just seems like a really stupid thing to disable a feature that is clearly aesthetic for only the epson's.

I found one reason why the immediate brightness change is beneficial.
When you turn off a nova and turn it on, for a second it's at max brightness then ramps down to the set brightness.
Epson is immediate .
I think that is why they chose that method.
I'm still stuck here.. I want the higher quality screen, but i get mixed reviews from the web.
Most people think that the novatec looks better, but is less accurate.
I would have to agree with that.
So then which one is higher quality?
I would like some background on Novatec/k/ch. I cant find much about them other than this website.
www.novatech.co.uk
At least for epson I have heard of them before and they are known for their imaging products.

The only time you will notice a difference is when you have two in front of you.
Or you obsess about it enough to research it to much and create a post on a forum about it.
I have a Novatec and I am glad I do. I don't like the look of the epsons that I have seen. And mine fades nicely.

I'm a huge fan of my Nova. I've seen both versions, and I much prefer the Nova's.
One thing I did notice between the two though: on my Nova, I can see vertical yellowish/off-white lines on pure white screens. Look closely, you'll see it too most likely. Bugs the sh*t outta me
But on the Epsons, I also saw the horizontal greyish lines the OP mentioned.
Just my $.02

So keep a nova with a stuck sub-pixel (only noticed it on blue), or an epson with an otherwise flawless display.
Last option is to complain and have them ship another one and hope it's a nova.
Why can't I have the whites of an epson with a nova screen! DAMNIT

Side by side with my friend's Evo. Nova vs Epson, and I had a hard time seeing a difference as far as brightness and color. I really didn't take much time to compare the two however.

It seems like the entire spectrum of color is shifted slightly warmer for the novas.
The Epsons are probably better since the spectrum is baseline and more accurate.
Pure white #FFF is perfectly white on the Epson.
On the nova its warmer, slightly yellow but that gives everything a more vibrant/colorful appearance..
All I need know now is that epsons are reliable and high quality lcd's

Two EVOs-One a Nova and the other Epson-My Findings

I just received my other EVO the other day and was wondering why there were such great differences between the two displays. I found that the one I've had for months is a Novateck and the new one is an Epson. The Nova is HW rev 02 where the Epson is HW rev 03. Both are rooted running the same latest Netarsky Kernel and OMJs latest ROM.
1) Confirmed that the Nova panel transitions smoothly between brightness levels where the Epson is instant.
2) Both have the same amount of poor transitional latency between mid-tones(grays) and whites/backs. Both have the same excellent transitional latency between whites and blacks (nice for scrolling text).
3) Viewing angels is exact between the panels. Both fade yellows to white at any viewing angle greater than 30 deg.
4) The Novatech panel has far greater apparent dynamic range whereas the Epson seems flat with a yellowish tint to it. The Nova has a slight but pleasant bluish hue cast with just the slightest hint of magenta. Empirically the Nova seems to 'pop' with more vibrant colors than the Epson.
5) Both EVOs score comparatively using Quadrant, LinPack, and FPS2D.
6) This is not releated, but worthy of a note; The New rev 03 EVO has a much better camera than the rev 02 EVO. The rev 03 EVO has much less noise and performs far better in low light. The differences are remarkable.
If any of you are interested, I will take photos of the two together at multiple viewing angles and demonstrating different color palettes.

Interesting... this has my views on the NOVA slightly changed since I had been praying that the replacement I was shipped wouldn't have one but now I wouldn't mind having it

The only thing about that the Epson has over the Nova is that Nova's dark greys have a noticable purplish hue to them.
However, a quick install of Storm's color profile hack and the Nova is now just flat-out beautiful.... unfortunately, there is nothing you can install on an Epson panel that will suddenly make it appear not as vibrant.

I had my Nova replaced with an Epson and the Epson is clearly the better screen, has true blacks and greys and hugely better saturation. My nova screen looked crazy washed out by comparison and the display EVO's at the store looked the same as my Nova.
Pretty much the only reason I asked for a replacement EVO albeit by different means was in hopes of being able to compare the screens and without a doubt I was keeping the Epson so it's interesting to read your opinion as it is total opposite of mine.
I posted some comparison pics side by side in a thread a month or so ago when I got the replacement, would be very interested in seeing some photos of yours side by side for comparison!
Thanks

I'll get those pics done tomorrow and publish them here. It is interesting reading your findings and makes me wonder if there is a color profile loaded into the display controller that can be recalibrated. I'm beginning to think that the issue isn't a Nova vs Epson one, but instead poor quality control during the display color profiling process(if there even is one).
Too bad I can't use my colorimeter w/ the phones to properly profile them.

What's storm's color profile hack and where may I find it??

I noticed almost right away that my rev2 nova battery life was much much better on both of them compaired to the epson revs3

Screen issues

I picked this phone mainly for the keyboard but also for the vibrant screen. However I am liking it less and less as I use it and wanted to be sure it's standard.
My main issue is the color shift. 90 percent of the time you are viewing inaccurate colors due to the shift in colors at practically any angle. This is compounded by the high oversaturation of every color to begin with. Yes, the screen is vibrant with suprisingly deep blacks, but it seems to have some major issues to me.
Is my experience normal here? Not trying to bash just a bit disapointed.

a panel like the ones we have really deserves an ISF or Avia grade settings menu... I agree they are oversaturated, but not like TV in a store bad.... have you compared yours to another?? Also, I noticed the oversaturation seems to be tied to the brightness control, if you crank it way down, you can see much more color distinction... maybe 20-30%? reminds me of badass CRT projectors, too bright for their own good, but the room to play is good. As far as viewing angle, ummm... mine seems pretty constant, but I havent actually watched a decent quality video. I need to break out a 'digital copy' from one of my BD's and see how it looks with better material. Anyone know if those digi copies can do 720p??? Never tried it, just had nightmares of win media player or even worse itunes style BS just to play a video. At least you dont have the backlight vs. brightness vs. contrast issue like on LCD... Thats a pain in the ass...
ill try to figure out a way to get my avia dvd on my Epic, and use the films to check the colors... any suggestions would be great, not so good with video conversion... video.ts to mpeg4? something???

I have not had a chance to compare to other epics. I do agree, backing down the brightness helps offset the saturation. The color shift when off center is always there, getting used to it but bugs me just like plasma phosphore trails (wouldn't trade for another screen but...annoying).

Wow seems I'm lucky. All my colors are vibrant but I wouldn't say oversaturated is the word. If its oversaturation you wouldn't be able to tell deeper details on objects because the color would blind you. I have no motion blur and my viewing angle only distorts at stupid angles I would never use the phone in. Surprisingly my only complaint is everyone's bliss. There's isn't enough brightness or there's too much contrast. I've downloaded a few 720p movie trailers. Specifically serenity. The blacks are so deep the crush depths of shadow and detail you should be able to see. Someone should work out a video setting changing... thing. I'm a major HD head and I've calibrated my lcds numerous times. My girlfriends epic has a yellow hue to it. I remember the first vibrants had a horrid blue tint. It varies. Happy I got lucky with mine. Personally I wish I could blow My epics screen to 40 inches at 1080p.... you hear me Sammy? I hate You but if you made samoled TVs I would love you. Lol.

You guys mean raising the brightness. Not dropping it BTW. That would have the opposite effect and then you'd lose even more detail. Dl a 720p video to your PC and phone and look for differences in dark areas.
Sent from my SPH-D700 using XDA App

I don't get any color shift until around 170 degrees. Are you talking about the trippy 3D effect you get with red and blue (especially text) on very dark backgrounds? I've always understood that to be an artifact of the different handling of subpixels.
Sent from my SPH-D700 using XDA App

I have calibrated a few displays with meters, it's deffinetily oversaturation.
The color shift happens at very slight angles. For example, I'm typing and the "white" background of this forum changes blueish when I wobble my sceen a few degrees. if I wobble it back and forth it looks like a disco light lol. Sounds like this might not be normal...

Yeh man from the sounds of it, at least according to my experience, it's not normal. I've never noticed ANY type of color, contrast, or sharpness deficiency. Quite simply, its the best display I've ever handled on a phone. Like some others, I recommend the lowest brightness setting when you can get away with it, if anything to simply reduce eye strain. The ONLY time I use max brightness is if the sun is directly hitting my screen.
For what its worth, there is a voodoo color fix. I don't think its been fully implemented into the epic, but from what I can tell, the implentations out there get the job done for those who have color problems (such as the infamous bluish blacks). I don't think you can do it yourself, but some ROMs have them baked in. The first one that comes to mind is BakedSnack. (PS: you'll have to go to bakedsnackshack.com to install he got banned from xda)
Sent from my baked and emotionless SPH-D700

I went to Sprint to compare and yes, my phone had significantly worse color shift. My new one (and the instore model) push slightly red off-center, but it's not near as dramatic. Obviously no display is perfect and I would much rather have a slight red hue at off angles than have it wash out like my GF's EVO.

[Q]Whitelevels and screen sharpness

I have only seen 4 galaxy tab 7.7's so far and I noticed all 4 of them really have bad white levels as compared to my galaxy note, disabled the auto power saving and there is a difference in white levels but its still not even close to the galaxy note at the same brightness level. Even at brightness 25% on the note the vs 100% on the tab 7.7shows 'dimmer'whites. This is not a rant but I'm just asking if the screens are calibrated that way or should I keep looking?
Also I noticed that the mdine engine oon the tab provides oversharpening to a lot of my photos and its so obvious and makes the images look bd, supercurio has the same findings.

It is a pretty big screen so it may be they limited the brightnes to save battery power. While the claim is that OLED takes less power than LCD that is not always true. When displaying white, OLED tech uses like 4X as much power as LCD. The power saving comes in when displaying images with medium to darker colors.
What is the "mdine engine"? Is this something that can be bypassed by using a different picture viewing app?
It is amazing how Samsung seems to always add some crappy image "enhancement" like DnIE or such crap. Why can't they just leave our images alone, as we meant them to be? It is freakin' OLED man. You don't need any contrast or sharpness enhancement you knuckleheads! OLED by nature is sharp and has great contrast! Duh!

I don't know. My 7.7 is super bright, sharp and with way warmer colors than my Note.

I'm thinking the samr thing that samsung might ne limiting how bright the whites can go duebto the screen size but based on what I've seen on samoleds some screens juat put out better white levels, not really brighter but whiter.
For the mdine its running system wide.

The samoled plus tends to have more warmer colors than the samoled, is the whites on your tab 7.7 'whiter' than on the note at the same brightness level?

Yes I believe so, Supercurio knows more about that stuff.
EDIT:
simulated example done in photoshop, anyone with the tab7.7 and better photoshop skills feel free to redo this simulated image

Perhaps one of the other reason that the 7.7's screen isn't quite as bright, apart from the obvious power saving reasons, is an effort to possibly reduce the OLED degradation (burn-in) effect.
Either way, although I certainly noticed out of the box that my 7.7 wasn't as bright as my Note (or even my GS2 for that matter!), I was never really bothered by it because (especially when you use movie mode) the colour reproduction is very accurate, and paired up with the contrast levels, it's still fantastic!
I guess, to me, white doesn't necessarily mean I need to put on a pair of sunglasses while looking at my screen lol!

I just wanted to know if the norm has lower white levels, what bothers me more is added sharpening on some images.

Yellowish? Not at all! At least not with my unit anyway. Sure it makes the screen generally warmer in colour, but IMO, more than anything, it makes the colours look more accurate and natural.
Give it a try! You never know until you do...

Well ever since the Galaxy S changing the color mode to movie mode gives a yellowish cast, this is probably dependent on the calibration on the screen we get in the first place. I saw a friend's Tab7.7 the other day and his white levels were really brighter than my Galaxy Note. FWIW, its still a luck of the draw when it comes to color calibration on the screen. But thanks for that tip, when I'll purchase the Tab I'll make sure to also check out movie mode and see if it hits my requirements.

Very bright noticed the same with the Note ,
Nexus was somewhat easier on the eyes at night,
But probably like you I like a very dim screen at night.
When the brightness is turned all the way down on the 7.7,
is any banding or other issues seen like many report on the Note?
Blacks are black I'm sure but how are greys that are near black.
On the Nexus they were fine, but on the Notes I seen they could have been darker?
