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.
Not rooted came with 2.2

My EVO is due to arrive Tuesday - how do I tell which screen I have? I was playing with a coworker's EVO the other day and I noticed how bland/washed-out the colors were, so I'm assuming Epson on that one.

Correct I prefer the Nova panels over Epson. I think most would agree.
got my replacement evo yesterday. came with 2.2 and is 0002 Novatec
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?

Exactly. or use dmesg via adb and search for epson or nova
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.
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.
My current evo is an epson, my first two were novateks. The epson sucks.

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.
First off, this isn't a thread about which screen is better.
There are 2 different types of screens on the HTC Evo 4G. One is a Novatec and the other is an Epson. I want to know if one type of screen is more prone to the bright spot than the other. If you don't already know which screen you have, you can tell one of 2 ways:
Option 1: Open ADB Shell or Terminal Emulator and type the following:
dmesg |grep -i epson
dmesg |grep -i nova
One will come back with results and the other will come back blank. Whichever one has results, that's the screen you have.
Option 2: Change your brightness in settings. Epsons change brightness instantly while Novas fade.
What is a bright spot? On many Evos, a brighter spot will start to appear over time. It usually starts about 1 inch above the back button. It is most noticeable on a completely white screen.
So tell me, XDA, do you have an Evo with a Nova or an Epson and do you have a bright spot on your screen? Please answer via the poll before posting. Thanks!
I have a Nova with a small bright spot.

Nova. Two bright spots.
Nova from June - no bright spots
Refurb Nova from October - huge, trailing bright spot
New 0004 Epson from December - no bright spots
I had a Nova from June and it had one bright spot. Now I have a replacement evo with a Nova and it has no bright spots. Both hardware version 0003.
June 002 Nova with 2 bright spots One 1" above the back button, and one small one near the middle like others previously mentioned.

Same. I absolutely hate it and it drives me nuts, so I got a Shift. Which is way quicker, somehow.
I've had 6 or 7 evo's. My very first one was a 002 Nova, and it had a huge bright spot. Since then, 2 of them have been epson's, the rest nova's. All have been perfect.
I'm on my 3rd screen because of the bright spot. Sprint keeps trying to tell me that it's normal and happens to all touchscreen phones including the iphone, even though NONE of the display EVO's have the spot.
So, does anyone have an Epson screen with the bright spots?
I have 003 hardware with a Novatec screen with no bright spots. Actually my third screen tho. First one had dust under the screen, 2nd one had a cracked bezel near the power button and they replaced the screen assembly.
Any correlation between overclocking the phone or heat in general with bright spots? Mine isnt/wasnt ever overclocked.
Luckily for me I have no bright spots. Launch Day EVO had none either, got it replaced in September. So far so good
0003 with nova and two bright spots
I've got an 0003 with a nova screen and two nasty bright spots. Are you guys having any luck with Sprint fixing these? I bought mine in October of last year, so I'm way outside the 30 days. I haven't tried yet but this has been aggravating me more and more recently. If you did take it in, did you go back to stock first? While root has nothing to do with it, I'm sure they'll want to argue the point.
0002 Nova here, I hadn't noticed it before, but I just looked and it looks more like an L, but yeah there's a bright spot there, there's also a smaller one like right above the Search button...
I'd be curious to know if sprint is replacing these as well...
003 nova from june had one. Got a refurb last month 004 nova almost in the same spot.
002 release day nova and my screen has one bright spot over the back button that is only visible when the stock splash screen is showing and the brightness is all the way up

Same here. Launch day 002 Nova.
Spot above back showed up very early, spot in middle took a couple of months. Both have gotten a little worse as time goes by.
Didn't take it in a while back when we didn't have root for one of the updates, and now the 004 hardware is out, and doesn't work with a lot of stuff. Kinda drives me nuts, but not as much as fighting with 004 hardware

So I took mine by the Sprint "repair center" tonight. They said since I didn't have total equipment protection they would have to charge me for the new screen, it was $35 which isn't a big deal so I said sure.
Unfortunately they didn't have any new screens. They had one that was on a phone they were sending back and the guy said he'd give it to me, but did point out a scuff on the bezel. He said that he'd be happy to put a new one on it when they got one but I could have that one for free. I decided to take him up on it. To me a scuff on the bezel is no where near as annoying as the bright spots on my screen.
So...he takes my phone apart and puts the new screen on. Powers it up and sends me on my way once it's booted. It was at the point I got into the car and tried to unlock it that I realized the touch screen didn't work. Went back in, he takes my phone apart again. Apparently a ribbon cable on the inside wasn't connected right. He hooked it up and booted my phone (without the SD card in) and the touch screen worked. Unfortunately when it booted something was clearly not right, probably because the SD card wasn't in. My launcher was sense instead of launcher pro and my wallpaper had been set to one I used a while back. No biggie I thought, I'll just restore my nandroid backup from yesterday. So I go home, and then realize when I get into recovery to restore that my volume rocker doesn't work. SNAP. Back to the Sprint store. The guy at the store then informed me that it appears that the actually buttons on the board are broken and it's not the rocker switch at all.
So...my phone went down in the computer as having a "known issue" and now I'll be receiving a free replacement. Unfortunately that probably won't happen for a couple days or possibly until Monday. What really stinks about the whole mess is somehow I don't even have the Android market on my phone so I've got a seriously beat up device. :-/
Yes, you should be able to get your screen replaced for $35 if you don't have insurance and free if you do have insurance. Unfortunately the new screen may eventually develop a new bright spot & as others have mentioned you may end up worse off than you started. Keep responding to the poll please.
Just a random thought, anyone wish they got a different color mt4g?
I've recently been eyeing the white one more. I've always been a black or silver phone fan but the white mt4g has been catching my eye more
yes...i was just thinking that the other day. either the white or the plum. can't get it now though.
I have the black one and I am looking for white one to stock out although the black hides the scratches
