Galaxy S4 ALL YOU NEED TO KNOW: Part 2 (Displays)

[@harle1183]

Erica, I am 51 and a retired engineer, I am impressed. I thought you were just another typical youtuber, you are one very smart young lady who really knows her stuff. congrats on your best video yet. I can't wait to see more!

[@JohnNathanShopper]

Your reviews are shockingly awesome. No other reviewer can explain these technical subjects so clearly.

[@JamAudiox]

Most professional and informative review of the S4 on KZbin or any other site. Other reviews repeat the same standard specs over and over but you actually did your research and delivered an amazing review! Thank you TheAngelofmusic1989!

[@vickymercury1]

The only review I've seen which talks about the HTC one blowing out the highlights. This is something I noticed when I compared both at the store and while watching videos, the HTC had a lot of areas with blown highlights. Whereas the Samsung rendered images beautifully without any washed out areas. I had actually wondered why I couldn't find much about it in any of the reviews. Overall a thorough review, and exactly the things I'd like to see in a smartphone review. Well done Erica !

[@caboyzcoti]

You are my favorite KZbinr, I love how in depth you get with the hardware.

[@JohnNathanShopper]

Only you, Erica, can say "HTC is using an aggressive dynamic contrast algorithm" and not have it sound like bad science fiction. You are the best.

[@BichoyBahr]

Amazing review ... I haven't seen a review with such an amazing technical depth and stating facts based on measurements and analysis, not just subjective opinions! Thanks Erica, you made my day!

[@AlienMatej]

Finally someone who covers all the problematic to new dimensions. I haven´t found anything at all you could forget. You really do the best reviews ever, thank you!

[@roaddogg800]

I'm so glad I discovered your page! I must say, by a wide margin, you have the best...most detailed and relevant reviews of these high end smart phones. Bravo! As I am about to buy either the HTC One or the GS4 at full retail price (no upgrade for me) it is extremely useful to learn this level of details. Thank you! Incidentally, the fact that you are indeed very cute is a surprise bonus, like getting a decent set of headphones included in a smartphone box :-)

THE MOST IN-DEPTH REVIEW OF THE S4 IN KZbin EVARRR (PARTS 1-3). Subscribed!

[@willcarter3206]

This woman gives better information then any one else reviewing phones.

[@aindjebazov]

The best reviewer I have came across. Can't wait for the S4 part 3 review. Pleaseee! :)

[@EricaGriffin]

If you really want to know, the best thing is to measure the display like I did with a colorimeter or use a DSLR and set a very long exposure time to capture any leaking light from the display when showing a black image.

[@Zetler]

I love your reviews. So much details and in depth. I wish more reviews could be like this. You should reviews other techs like TVs as well.

[@dga223]

another great review. no other cell phone reviews can compare. appreciate your detailed analysis of the hardware and software.

[@EricaGriffin]

If you want to burn it ever whatsoever then go with an LCDs display, which has a much longer outlook in terms of any sort of burn in. The burn in I have right now is very light and keep in mind that I use my device all day every day as a tool for my job. So if you are not a heavy user like myself, I imagine it will take much longer to see noticeable damage. But yes, you will eventually have some wear on this display from text boxes or the keyboard or the status bar.

[@FakeItalianoII]

Excellent, accurate and very informative review, Erica. All four S4 videos ! Thanks !

[@ojstagg93]

Quite happy with my display. But it is really interesting seeing all the comparisons and stats. Great Video Erica

[@EricaGriffin]

You can't erase the burn in as it is wearing of the display. The worn parts can't be revived. If you use one of these screen testers you are only wearing the display at an equal rate and the burn in will remain. To balance out the wearing I would use the negative color mode under accessibility. Doing this will invert the less worn parts to wearing at the rate of the more norm parts. Eventually it can even out.

[@EricaGriffin]

No, infrared is not a part of the visible electromagnetic spectrum. However, the camera is able to show it.

[@I_V_L]

your reviews are the best among all out there! Thanks :)

[@EricaGriffin]

Absolutely! It will be sharp similar to the HTC One but it's a larger display than the HTC One so the One still has the upper hand.

[@GaryW48]

Thank you for showing me that I wasn't crazy when I started seeing burn in on my S-4 after 2 months.

[@EricaGriffin]

I do know what you are talking about. You must have the snapdragon variant of the S4. The S4 has seven automatic mDNIe modes that are each applied in a particular scenario. For example, in the gallery there is much different processing than in the UI or Launcher. The gallery Scenario called with echo 6 has a ton of sharpening. Then when applied as wallpaper you see it as UI mode without sharpening and with different processing.

[@EricaGriffin]

That's dynamic contrast. That is just dimming the image, it is not really adjusting the saturation. It's meant as a power saving function. It can't be disabled.

[@HarryIsa]

No one review as detail as Erica. keep it up^^

[@EricaGriffin]

So if you download a 1080p image it is 1080p in landscape with a height of 1080 pixels. But when you apply it as a wallpaper, the portrait resolution height is 1920. So you need an image with a pixel height of at least 1920.

[@ramonkroutz]

Thanks for your videos. I was getting tired of hearing the same stuff in every other review. yours is way different, way better. thanks again.

[@SelinaTynes]

your reviews are just the best ... impressive as always... i love you

[@EricaGriffin]

These lines don't represent devices. They represent the 3 color channels of the 3 subpixels: Red, Green, and Blue. Together, red, green and blue at different intensities make up all the colors you can see. (0,0,0) black or (255,255,0) yellow or (25,100,100) greenish blue of some sort. For Gamma like I was showing you, all 3 channels on the S3 went high up (high gamma) in shadows, so their brightness was turned down to black. High gamma means dark.

[@Mr2pint]

Wow very comprehensive review, which is much appreciated!

[@jordanwalter6570]

the star pound zero star pound thing worked on my really really old samsung phone, we're talking 2008 here, it even has a tester for contrast and vibration. Wow I didn't know this existed, thank you!

[@LifewithJeremiah33]

you just gotta love her reviews

[@PrakashSoni-cd7rj]

Her website and her channel will go far ahead I see 1k subscribers adding to her channel in every 3 4 days becouse she is doing amazing superb and best work keep it up really helpful thanks

[@Aelentel]

Thanks so much for the in depth CIE analysis of the display, is was eye opening.

[@EricaGriffin]

You must have opened it in the web browser. Download it into gallery. But anyway, the point is that unless you are in the Samsung Gallery or the Samsung Movie Player you won't have the clipping issue.

[@kacaramel]

I don't care what people say your review is very well informed and detailed and I really like it and it helps me think about what I should really buy, this is why people have problems with their phones and complain later on because they don't know about these fine itty bitty details and then they bitch and complain about how the phone is shit. Shut up and be glad that she's taking her time to give us a well structured review, or even better don't watch it, ungrateful...

[@Hydrocortisone100]

You go above and beyond. Awesome, just awesome.

[@Tritonal92]

Please make an in depth review of the HTC One! I love your reviews!

[@sahibjeetsingh1786]

I am having s4 today in april 2016 and I am proud of it

[@edj]

Well, this video is so long, but i manage to watch all 3 parts. very nice

[@MaskedMammal]

Man.. I'm so jealous right now. When I got my Xperia Play I was enamored with the screen. As my first smartphone, it looked so much better than other mobile device screens I'd used before, it kind of blew me away. Lately I've been gawking at my friend's Galaxy S3. It's such a big screen, and it's so responsive and bright and the color is unbelievable... To know that the S4 is THIS much better, I can't even imagine what it'll be like. I'm planning on getting the Note 3 so I hope it's just as good

[@CJEndowed001]

Finally I got my colleague's S3 for cheap and awesome condition, been in a protective case since day 1. I had been waiting for S4 so long, even skipped the S3 last year but fm radio absence was really a game-breaker for me. SO that's what!

[@MrKreweesti]

Your reviews rock! A big thumb up.

[@EricaGriffin]

First thing would be to see if the image or section is really black. Where are you seeing this? I only see this on images that are not truly black. It's an issue with my panel calibration. The red channel is too bright so it shows on near black shades.

[@TheBeekay23]

I watch only you and MKBHD for the non-biased and in-depth review :)

[@EricaGriffin]

From fully off to on with a display of this resolution, you better bet that you can get a small bit of latency. Remember, the pixels ARE fully off and have to turn on again. It is different if they are not entirely off or black. So that is what Samsung did. Set pixels to 8,8,8.

[@TheErmin36]

very intelligent and in depth review. Thanks for being awesome and sharing it

[@EricaGriffin]

Both snapdragon and exynos have scenarios. Some a tad bit different from the other but I am positive it has to do with your problem.

[@EricaGriffin]

There is no problem with the phone. Even the Web browser has its own scenario and you will even see a brightness change upon opening or closing the Web browser. If you want sharpening, which is no good by the way and is quite aggressive try echo 6 > /sys/class/mdnie/mdnie/scenario in terminal emulator for android. This will apply until you restart the phone. All it does is turn on Gallery Scenario for everything.

[@EricaGriffin]

Well, I have the measurements saying it's not good. There is no argument there at all. But if you like it that is all that matters. To me I am very sensitive to what is right and what isn't and so are many others so I call it terrible. If you get used to looking at wrong calibration for so long what can you expect?

[@TBONEV999]

Ur Knowledge deserves accolades...:-)..And itz between True White & true black, but seriously when I used S4 & changed to HTC One I immediately noticed the difference in Display. One exceeds beyond imagination whilst Samsung are taking safer approach. But now they decided to scrap Amoled and instead go with LCD for S4 Active..lol

[@paskalajz]

Best display review ever! Thank you!

[@EricaGriffin]

What I show here aren't bugs but functions of the screen set forth by Samsung.

[@Kunki7]

Your reviews are perfect!!! I relly like your deep info about displays :-)

[@EricaGriffin]

still having a little bit of network issues. I will release it as soon as I can. But please don't ask anymore.

[@avsolanki94]

seeing pixels in any sort of display depends on the distance from which you look at the screen. for example, if you are sitting 8-9 ft. from your tv then you won't any pixels or subpixels even though a typical tv will have density of just 50-70 ppi. but if you give your tv screen a closer look, you will see pixels and red green blue subpixels. so what steve said was just to promote his iphones..

[@randalx]

Great review! Excellent research. Extremely informative.

[@EricaGriffin]

Yeah... Look at the link in the description please.

[@MsSam676]

damn that's the best review about s4 ever saw..

[@ginnotey]

very detailed review. im leaning towards the s4 now. before it was the xperia z, then the htc one, then now the s4.

[@ConstructiveComment]

Very nice review as always :-) I think you should link to part one with an annotation. The link to Part one in the description has a few characters missing off the end..

[@MuhammadAsif-xe7mg]

you are the best phone reviewer on youtube ;)

[@Ashtonian54]

Another excellent review

[@halfveggie]

The review is awesome and very technical too :) what did u study in your college??

[@alvaroo21alvaro35]

ive got the s4, and lm happy with it!!

[@anshul_rajput]

was waiting for this

[@FernandoJFDSilva]

Thank you Erica for such amazing review !!

[@adipalm82]

You know your technology wow amazing you went deep down to the core

[@joeclectic]

Wow! A You tuber who knows how to make a video that won't leave you wondering what the hell they are talking about! I LOVE IT!!! Excellent!

[@paqois]

Best reviewer on the block :)

[@CudlyCuthbert]

Wow! you really know your stuff, my brain hurts :D By far the best, most thorough review I've seen.

[@EricaGriffin]

I know :/ I mentioned that in the burn in section.

[@EricaGriffin]

Do you have adapt display selected? It adjusts brightness and contrast. Also, do you have auto adjust screen tone on?

[@carlosdoerner]

I really liked your videos, congratulations! it's pretty professional to me! :D

[@Dreiyse]

You are the best reviewer ever :-)

[@davidjackson2661]

I appreciate your help,thank you.bought the phone 9 days a go

[@astromeritis07]

Great video. deserves more views for sure!!

[@naftIU]

the best review, ever.

[@jarichiverson]

So what would you advice? Galaxy s4 or google nexus 5? This choice is soo hard for me...

[@EricaGriffin]

Not really. I hoped it would. I guess what really matter is how long you have the static image displayed. I now have burn in from the Web browser address bar. I have kept my phone on auto brightness since day 1 to test this theory. You will burn in at some point no matter what. =(

[@TheBcoolGuy]

Yeah, I know, I just live in such a bland area. :P It's just a bunch of dark-green pines, a really white home and that's about it. I really love the S4's display, it is awesome. BTW, I think it's amazing that I'm talking to the almighty You right now. I am just a little Swedish boy making my way in life. Do you think it's cool that some random Swede watches your content? I mean, also, I can't believe you actually sat down, thought out what to comment and then commented it. I can hear you say it.

[@Sigkeeper1]

I am switching over from a dinosaur Blackberry to the S4. I just received the phone late yesterday afternoon and have been reading what I can on this phone, have reviews and reports and paperwork flying in every direction. I just bought a 32 GB memory card for this thing so I want to see how it plays out and functions

[@MrEnterainment]

Ur vids are awesome keep up the good work!!

[@eval_is_evil]

I confirm the burn in issue.,,my S1 has horrible burn in lines. But it started really showing after 3 years of intensive use

[@EricaGriffin]

no, they don't pay me dime. or any royalties. Once in a while, as I am a member of the press, they let me borrow units to look at. Otherwise, I still buy everything.

[@Lostatsea23]

Thanks for this. Loved this phone but HTC one was the best choice for me

[@captaindorzy]

Idk much about all this pixel stuff but i think that for the S4 there are many more green pixels but they made then smaller than the blue and red, so it all works out well.

[@BryanMorganMusic]

Erica, have you experienced the issue where the screen is supposed to be total black, but there's a faint reddish glow to the black sections, indicating that some of the red pixels are still barely on?

[@hughhemington9559]

I've really enjoyed my S4 for over six months. The only two issues I have are that the OS "nags" me when I turn the sound volume up, apparently ignoring the possibility that I'm using speakers instead of ear buds. And, with button(s) on both sides, I can't easily use the bubble level app.

[@britobintu]

Great video.. Thanks for sharing ur knowledge. Loved it!

[@TheXxbeastxx420]

I was falling a sleep during this review dont get me wrong its still was one of the best reviews out there cause erica is the best

[@tisoyboy2]

I think her reviews stand out amongst the rest. Maybe you (piyathdroid) should stick with professional display companies and stop spamming the review. Thanks Angel for the extensive review. You have made my phone purchase decisions a lot easier to make.

[@EricaGriffin]

Hence part 2!!!!! I will mention this when I get to talking about the processors. Tough crowd lol

[@qwertyabsurd]

A few questions for you Erica. Why do you think companies don't make phones perfectly calibrated to gamma 2.2 & stay with sRGB, perfect dot spacing & perfect triangles without any over or under saturation? There are those that want the exaggeration of amoled & there are those that want the a little more realism in the HTC, but is there a market for those that want a perfect display?

[@TheCapedCoconut]

You should throw a link to the first part in the description .

[@root9065]

Can you imagine what KZbin would be without your reviews? Me neither.

[@benjmiester]

@15:00 yeah my LG plasma does this too. I set the dynamic contrast to really low and just turned up the actual static contrast. Problem almost completely solved! :D Hopefully they will let people fix this, or I guess a custom rom will help with that otherwise.

[@TsakaneMaluleke]

Please do a display comparison between the Z, S4 and One with charts and videos for all phones. And if the ZU is out by then you could throw that in too, I'd like to see the new Trilumious* display. Thanks

[@Nino88_bb]

Yeah....I actually was stupid enough not to look at the description. Thank you. :) About the Z display...you can actually see all numbers up to 3, but every number is way to dark...and shifting colors from number to number. I'll try to take a picture of the screen and show you what I mean.
