Ok, so today I received a new evo. I knew it would be 003 and probably have an epson screen. well it was and it did. I was bummed because I like my nova screen anyways, I thought well I'll switch em! turns out, the ribbon cables are completely different between the two. although there are still 3 for epson, the bottom one is dramatically bigger.
After noticing this I got a little more curious about the differences. one major'ish one, is you know those little gold round things that are kinda like a tiny dish with the black inside? (I have no idea what they are called) well they changed the type of those and there is one missing on 003. on 002 there was one connected to the wifi/fm chip, well that one is gone now. (its located right above the rumble motor)
Not much info but this is what I noticed. feel free to embellish. here are some pictures
I'm sure this has been discussed at length, but what's the difference between the 002 screen and the epson screen?
My replacement that I just got has an Epson screen and I hate it. I want my Nova back! Both were 003 though.
Epson has a truer black but novahas more Colors and is more vibrant. I miss my nova aswell, epson looks like an old tv lol

how can you tell which screen you have?
jerryparid said:
1. Connect PC to Evo in charge/development mode; then adb shell dmesg > evoinfo.txt. Look for "novatec" or "epson" in the txt file
or
2. Download terminal emulator from market, type dmesg, find "novatec" or epson" in the output
or
3. Add HTC Power Widget, change the screen brightness. Instant change = Epson, gradual/fading change = Novatec

That's what some people say but I put the two side by side and my nova was blacker, brighter and way more vibrant. It was better in every regard. My new phone is snappier though, and performs better than my last one ever did so I think it's a fair trade off. I'll get used to this screen.... eventually.

HW Revision and screen manufacture have been discussed at length during the first few weeks after launch.
Here are some facts....
1. All 002 Devices are Novatec
2. 003 Devices can be Novatec or Epson.
3. 003 Nova/Epson > 002 Nova. 002 Nova just doesn't look at as nice and some units suffer from manufacturing issues.
4. 003 Nova has much deeper colors than 003 Epson. If you ever looked a Galaxy S, its AMOLED looks like a glossy candied apple when compared to Evo's display. Nova makes Epson looks this way.
5. 003 Epson can produce truer black, while most 003 Nova generates a dark purple black.
It took me about a day to get used to my new 003/Epson.
I miss the gradual brightness level transitions most, the color differences don't bother me. My gf's Nova does look more vibrant but looking at them side by side I think the warmer tone on the Epson is slightly easier on the eyes
thanks for the info
Just figured out that i have 003/Novatec. Wasnt able to appreciate the colors until i took the anti-glare screen protector off. Boy was there a difference.
Color is very vibrant. Ill have to check another Evo and see what that screen is.
Yeah the ati-glare makes it suck.

For those who hate the purple tint on Nova displays: CM6 comes preloaded with a color calibrating app. I used it and although gauging with your eyes isn't perfect, I got it to look reasonably calibrated. Looks near perfect now.
I think you might be able to load the app on a Sense ROM but I'm not sure if there are dependencies. Search through the Nexus One forums for it.

Didn't work for me on calkulin, it crashed when I tried adjusting. I tried both versions.

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'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.

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.
Just a PM response, but I figured I'd just post it to the public...ive been thinking about this for a while now...
colors on NOVATEK are horribly wrong... I think they might be the AMOLED screens that HTC had originally announced the phone with... Then they noticed the color issue with the new AMOLED technologies and reverted to the EPSONs.

Neither Novatek or Epson make AMOLED panels (only Samsung and LG) and if it was an AMOLED screen it would be noticeably better

The new phones have nova panels last I checked so they didn't switch anything to epson. If anything they ran both as tests and picked nova for whatever reason.

Mine is Novatek and black levels are amazing. Color quality is good as well. I have seen Evos with the purple tint though. I just don't think it matters what screen type it is.

very interesting... i thought all novateks would have the hue discoloration... perhaps its something that will soon be hacked out... either way, im happy with my epson
I have a related question.
I actually have a 0003, with the Nova screen. Is there a difference between the 0002 and 0003 models with the Nova screen?
Tilde do you have a 002 nova?
My 003 nova looks quite good
Swyped from my Evo 4G
I like the vibrancy of the Novateks over the Epsons anytime. Whether there is a pinkish hue or not is only distinguishable when setting it side-by-side with another device as your eyes are constantly adjusting the white balance to the brightness color you see. Therefore, the hue goes unnoticed most of the time anyways.
BTW, both screens are definitely not AMOLED. I wish Novas were 'cause then I'd be using the red tone tweak and would be saving 42% of battery life as it's been tested with the Nexus Ones.
I have a google io 0002 novatec and have compared it to a 0003 novatec and mine is noticeably brighter and more vibrant than the other one at full brightness. i do detect a cooler color temperature but it's only noticeable in contrast with a screen with a warmer temp. who is to say either one is incorrect? they both appear color accurate individually
My cousin darrell told my other cousin darrell that my first cousin darrell that his face kinda red. Figured it was from being in the sun a little longer then he aught to have been in it. But to be honest wit cha i reckon i wouldn't have noticed if darrell hadn't said nuffin. Its a little red but ain't too red i reckon.
Its like that little ding in your car door. It's small until someone points it out to you. Then all of a sudden WOW it got bigger magically.
The Nova panels are fine. Flash some ROMs or read a book.

i was going to say the same thing.. now the samsung moment, the colors on that screen are all jacked up.. but thats for another section in the forums!
love my 0002 NOVA. the screen is stunning and no matter how much I try to find flaws in it , I can't
I have a Nova and an Epson on hand right now and i prefer the Nova to be honest. The colors seem richer and not washed out.
so i got my new evo 4g yesterday but this one has a purple tint and is driving me nutz its a Nova 003 my first evo was a Epson 003 but had alot of problems so i got sprint to send me another phone and now im sending my old one back .. my question is should i call them back and go crazy about the purple tint or just be happy that i was able to get a replacement with no cost and only took 3 days?
Be happy you got a replacement that fast.
I currently have 5 EVO's (2 replacements) 1 for myself and 1 for my wife.
All but 1 are Nova screens. The last replacement that came in yesterday is an Epson. I immediately noticed the difference.
As many of the people that have had both a nova and epson screens in hand, the Nova may be pushing purple a little bit more but the Epson's contrast and overall brightness is lacking comparing ot to the Nova. The Nova's look much more vivid to me where as the Epson looks washed out. This tested with all devices on max brightness.
Even with the purple hue, I'd choose a Nova over an Epson all day long.
So I am left in the same situation as you except I want a good working Nova instead of this inferior washed out contrastless Epson!

Not sure if you are running any roms, but CM6 has a few options that change the color, aka "calibrate" (a stretch of words to be sure). It may take the edge off the purple tint.

Correct I prefer the Nova panels over Epson. I think most would agree.

After some reading, looks like the only way to tell which screen (without having 2 evo's with different screens in front of you) is to adjust brightness and gauge from there? If fast adjustment then epson, if gradual then nova?

Just got my brand new evo 4g 2 hrs ago its a white 004 w hboot2.10 de 3.70 out of the box screen looked like purple,so I checked via terminal emu,dmesg and guess what its a novatek screen not epson,I thought these where pong gone w 002/ and some 003 but these is a brand new one....should I keep or exchange so I can try to get an Epson..my friend is a best buy mobile employee he will swap it ,but is it worth swapping?
Are you dissatisfied with the screen? If its not bothering you, then exchanging for a different one seems like a waste of time.

Care to add some more info as to why epson sucks so much?
It is incredibly washed out compared to both of the novas. The whites are kind of yellow, and the blacks aren't nearly as deep. It is a lot duller all across the spectrum. Also, for some reason it seems that the dithering is more noticeable on the epson, though that could just be me being nitpicky. When I first got it, as soon as I turned it on my heart sank and I was extremely disappointed. Side by side with the nova it looked like a joke. I have gotten used to it now but man I miss my last one. Also, neither of my novas had the purple problem, both had a nice deep black to them.
It's all a matter of personal preference.
Let me give my own personal experience with BOTH screens...
I have owned both novatech and epson equipped EVO's. Here's my opinion on the matter. First things first, OP keep your 0004 novatech EVO! It's very rare and a very good combo to have.
My experience is this: My very first brand new EVO was a 0003 with a Novatech. I never thought anything was wrong with it's screen whatsoever and my wife's EVO is exactly the same with a novatech. Last month I had to do a warranty exchange due to constant random reboots and my replacement was a brand new 0004 EVO in the original tv dinner box. As soon as I booted it up for the first time in the store I noticed right away the screen just didn't look right so I fired up my first EVO and put them side by side. To my suprise the difference is VERY noticable.
My first impressions and complaint about the new screen was that it looked "dull" and less vibrant. Also the whites where not as bright. I was hesitant at first to leave the store with the new EVO because I didn't think I was going to be able to get used to the "dull" whites on the new phone. But I had no choice because my original EVO had terrible reboots and was beyond usable.
So once I got home and used the new epson 0004 EVO, I slowly got used to it and was perfectly fine with it. After using the new phone for a couple of days it actually seemed normal and at that time I got my wife's 0003 Novetech EVO and compared them side by side. Right away I saw that her EVO had a pinkish/purplish tint to it compared to my new EVO, especially when viewing it at an angle or from across the table. After comparing them for a few minutes I quickly realized that my new epson screen actually had more accurate colors than my wife's novatech. So I shrugged it off and used my epson for several weeks with no complaints or concerns about the differences. I can honestly say that it's all a matter of user preference and neither screen is better or worse in the grand scheme of things.
But just a few days ago I had to exchange my epson EVO again due to technical problems and a bad antenna. Low and behold when I went to the Sprint store to pick up my new EVO it was another 0003 novatech. I knew immediately when I booted it up because I'm very familiar with both screens now. I was hesitant at first to accept the new novatech phone but quicky came to the reality that it is just as good as the epson and I remembered it has a brighter screen with brighter whites which is fine by me. The pinkish'purplish tint is not noticable once you take the phone and start using it. It's only noticable if you put both novatech and epson side by side. You will quickly adapt to either screen just fine. ...The same way you get used to other peoples LCD TV's with slightly different color temps. It's no different, trust me. I'm VERY picky and if I can adapt then so can anybody else.
The only other significant differece between the two screens is the way they change brightness levels and the dimming. The novatech has a very smooth transission when adjusting screen brightness while the epson screen uses step by step increments. Also the epson screen does not have a gradual dim when the screen goes to sleep, it is instant on and instant off. Personally I prefer the novatech's gradual smooth screen dimming and brightness adjustment over the epson. To some of you it may not matter, to others it might be the big deciding factor. Both screens work fine and I will settle for either one if I ever have to do another warranty exchange or insurance replacement.
I hope my opinions on this was helpful for those of you still wondering which screen is best suited for you.
EDIT: you can adjust the color temperatures of both screens by flashing "calibrated-signed-42-Universal.zip" and then installing the .apk called "Calibrator-5.1-Universal.apk. Just such here in the EVO forums, I think it's in the general thread. Works most excellent on my novatech!
How could I check which screen my evo has? I know its a 0004 for sure I got it after Xmas.

Well I just wanted to know if there's was a difference on performance and display I just realized my WiFi won't connect stays on obtaining up address but never connects...
I think tx_dbs_tx sums it up nicely, I have a novatech but know a couple of people with epsons and it's really just preference. You can always adjust the colors if it looks too purple for you.
I have had a few 03 Evos, but just got my first 0004.
a few observations about 0004:
-battery lasts longer, even with stock and full bloatware installed. The first charge lasted 24 hours with a lot of web browsing! (my first few charges with the 0003 was getting maybe 6 hours.)
-I let the charge go dead, and fully recharging took around 1 hour! This is perhaps 3-4x faster than my 0003 handset takes to charge.
-The screen seems to be higher contrast, though this might be my imagination since i do not have the two in front of me for a direct comparison.
I disagree. My wife has 004 and battery life/charge is the same. As far as the screen, It does go brighter at max but colors are not as warm. Contrast is not as good. And I hate that it doesn't fade.
Power and volume buttons are taller as well. Which makes it easier to accidentally unlock it in your pocket.
The only thing "not" better about 003 is the issue with the gingerbread sense Roms which I'm sure will be fixed by time official update is out.
Sent from my PC36100 using XDA Premium App
I wonder if all 0004s have the same screen.
idc, how long do yours take to completely charge?
Also to accidentally unlock it you would have to push the button and slide the screen...I have not heard of this as an issue.
Not all 0004 evos have the nova screen ( 2 different panels), I've seen a few epsons. The nova panels have the brightness issues with GB leaked roms not 0003(Epson). The other evo is my household is white 0003 Epson screen and my whites look whiter while 0003 whites look pinkish or yellowish at times. I feel like overall my 0004 nova has way better color than the Epson panel; epsons just looks dull to me.
