BSOD - Verizon Samsung Galaxy S7 Questions & Answers

I have a SM-G935V S7edge that no longer has a display. Blue and green and red LEDs work fine. Back and recent buttons light up. I can even navigate through the phone with sideSync but absolutely no display at all. Bad display board? Can I make necessary repairs with my rock and hammer? Qouted 359.00 for display board replacement. Any advice would be greatly appreciated.

For one thing, Wrong forum. There's a specific forum for the Galaxy S7 Edge.
I'm going to assume that you mean the notification RGB led above the display. And if that's the case then that sounds like a bad display. If you try to repair it yourself then you will be in for a nightmare. I can't post links yet but check out JerryRigEverything on youtube for a S7 Edge teardown. As he says in the video, it's not easy, even touching the LCD while removing it will break the LCD and the most likely crack the glass. The replacements for the edge series displays are also very expensive compared to say a replacement iPhone screen.

Screen replacement

Hi,
Dropping my phone was the worst thing that could happen with my phone.
I found someone who would do the screen replacement and after nearly two months he finally returned the phone two me.
At first glance it seemed ok but closer inspection have shown me that:
- the panel used was JDI instead of LGD so a japanese panel instead of the 'original' LG
- serious screen bleed contouring the whole screen
- highlights on the screen, points in the screen where I can clearly see the backlight being brighter than everywhere else
- luminosity is lower than the original.
The last two points are very annoying. I compared my phone with a phone displayed in a shop and I see that the screen on the shop's phone is brighter that mine, even without adaptive brightness and @ 100% luminosity.
Could this be due to different panel manufacturer (JDI instead of LGD)?
The screen bleed could be due to the screen being badly glued but I am not sure...
But the bright speckels are annoying also. In bright areas this is very much noticable, a white picture shows two small areas brighter which indicates to me that the back of the panel has something behind that 'pushes', hard to explain.
Anybody had similar issues or had his screen repaired?
You can see my issues in the attached screenshots...

I don't think your issues is the panel type, i replaced mine and got a JDI from eBay. I don't notice any difference from my old one, which was not JDI. I would say you just got a poor screen. Not the fault of the installer either, i would try to get hold of the screen seller, or just accept the loss and replace it again.

I can agree that the panel type is not the culprit but the screen bleed is definitely the installers fault.
I am not very happy replacing it again as the total cost would mean that I could have bought a new phone for the same price...
My feeling is that the seller of the screen has delivered a used screen and damaged the silver back of the panel by removing it from the old device (the bright highlights could be from a prying tool used while recuperating the screen.). Too bad , lesson learned = do not drop the phone as the screen shatters very easily and when repairing, find a reliable repairsman...
Accept the loss seems to be the only option in this case...
Maybe I will have to disassemble/assemble the phone myself and do with with extra love and care and sense of detail....

Since the digitizer comes glued to the glass I'm more inclined to blame the screen/seller than the installer. But you know the saying... "If you want it done right...". All the best on getting it sorted and working properly.

Screen faults on Galaxy S7 Edge

Hi all,
Has anyone had problems with white horizontal lines and flickering on their Galaxy S7 Edge?
I bought mine from Samsung's UK shop online. I've tried on numerous occasions to contact Samsung UK's support, telephone, online chat, email etc. They don't seem interested in helping, even though the phone is in warranty. They don't even reply to emails...
I've twice been asked to call the online sales number +441628 918334. On both occasions I've been told that they are not allowed to replace faulty devices and I have to ship the device and headset back and claim a refund.
So basically if your device goes faulty, even in warranty you'll never get another S7 edge....
Thats a load of crap
should I have another go at them? It is odd, generally companies arrange a courier to pick up the faulty device and swap for a working one.
amoled screen quality is a huge issue. i just got my second device today, the screen of both devices is very different, especially in regard to green or pink tint, as well as the stability when looked from low angles.
i made threads reagarding this before, see here:
http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
http://forum.xda-developers.com/showthread.php?t=2463786
what you describe could be the following:
flickering: is due to PWM modulation, which is a energy saving method. some people are more sensitive about that, some less...
white lines: i guess you mean that there are areas (lines) which are more bright then the other parts of the screen. its very subtle an best seen when you move text etc. around the screen. this is mostly due to the glueing process, when the screen is not evenly glued...
hope this helps a bit...
thanks for the info!
This new flashy phone is that flashy it's now like a white strobe light at the bottom inch of the screen. Good job I don't have epilepsy. Will phone them up again after lunch.
Found a complete solution here.
Works like a charm.

The sides of the S7 edge leak light from the display.

We need a stupid name with this... I don't know if it's a gap or the glass is so thin that the light will leak through. To find out if this happens to you, Google "white" go to images and put your phone on full brightness and go in a dark room and you will probably see through sides of the phone growing lightly, I don't think it should be visible during normal daily use but I found this while in bed. I will have pictures soon I don't have any phones with usable roms at the moment.
yaa.. same here with gold s7 edge
There is no back light like ips displays. There for cannot have light leak. What your seeing is the side angle of the display because it bends. Test this by recreating the situation then turning the phone so the edge part of the display is facing you.

I gave my S7 edge back for warranty repair because the screen stopped working. They changed the screen and now my repaired unit has the same issue. I'm pretty sure the original one didn't. See the pictures. Do you guys think it's normal ?

It is normal. It's because of the curve of the glass, that's all.
Yep i see those too in my device, but i highly doubt people check their phone in that angle.
Sent from my SM-G935F using XDA-Developers mobile app
As others have said I don't think it's a physical gap in the glass but more of a reflection of light against the edge of the glass. I wouldn't worry about it.
It's normal. Every S7 Edge will look like that. It's just physics.
I am 100% positive that it comes from under the glass and not a reflection of the edge.
I even put a black tape on the edge just to be sure.
Do all of your S7 Edge look like this ?
I have same thing pretty sure it is light bending off the glass and reflecting at an angle that it illuminate the outside edge

Hi Guys,
mine also does that after I replace my cracked screen.
Samsung has released a statement about this. Just google: Light leak Samsung Galaxy S7 Edge, and you will find it in the first one from Samsung website.
Hope this one help.
Cheers

I dont think it does this because of the curvature of the glass, because if you add pressure to the screen the "light leakage" sort of goes away.

lol, I've seen that. but I'm just saying, from my observation I noticed tiny spots along the line of light at the edges, possibly dust or air during production of the phone. If the light was caused simply because of the bend of the screen, wouldn't it be a perfectly straight line?
i dont know if your still going on about this but the top speaker also lights upcause of the light leak

Anyone else have blue color shifting when viewed even a little off-axis?

I received my Axon 7 on Wednesday this week. The AMOLED screen does have very good blacks and looks vibrant, but there is an issue I haven't seen discussed - I'm trying to determine if its just my phone, an issue with AMOLED in general, or perhaps a coating specific to the Axon 7:
When I view the phone directly, whites look correct (warm, natural or cool depending on the Display setting). However, turning the phone even a little off-axis, 10-20° either vertically or horizontally, introduces a very small blue shift - whites especially take on a bluish, sort of washed-out cast. It makes the colors seem much more shallow and unreliable. Can those of you who received your phones go to a WHITE or light-color screen and report if this happens for you too?
This is actually hard to identify, most people will just see something is a little "off" - to my eye, it looked like a very subtle version of a TN-panel color shift. I never have seen this on an IPS panel, though off-angles may get washed out (see Nexus 5/5X) quickly at 50-60°, they always retain their color, even if it lightens. Or, e.g., the Moto X Pure 2K IPS panel that I'm coming from has zero off-angle color shift, no wash-out, and just darkens a little even at 180°. This is my first AMOLED panel, so I'm not sure if it happens often.
If anyone can help me determine whether this is a defect or an expected limitation, that would be great.
I've noticed it on my A7 too. This is my first AMOLED phone, so I too am not sure if this is normal.
I see it also. Thanks a lot now I won't be able to insert it.
For now I will blame the screen protector that came in the screen.
Welcome to Amoled.
The cheap screen protector contributes too,
Thanks, all - I guess it's just the phone then. I actually don't have the screen protector insert applied, so I assume the "screen protector" refers to the factory glass overlay.
Does anyone know if even the new Samsung AMOLEDs exhibit this shift? I think the Axon 7 is technically a Samsung panel, but I wouldn't be surprised if Samsung kept the best AMOLED technology for themselves.
Not sure this is a dealbreaker, but it's definitely a step down from the great color-true viewing angles on the Moto X Pure. (Too bad Moto abandoned the good design the Moto X Pure had for gimmicky snap-on modules this year rather than iterating - it seems like the Axon 7 is otherwise the spiritual successor to the MXP.)

Of course Samsung keeps the top production panel for themselves... However, it's still a great panel according to colorimetry tests.
Don't notice it on my unit. Jumped from a galaxy S7 edge to the Axon 7 and the display looks exactly the same to me.
This is an area that has driven me a little crazy. I'm used to my Samsung AMOLEDs (Note 4, Note 3, S3, etc.), and they don't have any noticeable "shift", This screen is gorgeous, but it's not a top-tier Samsung panel (obviously). Still, small price to pay for a 400 dollar savings over a Note 7. I am also positive the matte screen protector isn't helping. Once my tempered glass one gets here, I will switch it out and see if it makes a difference.
Which tempered glass screen protector are you getting? I have not read one good review for any of them...yet.
As an update, I went and tried some floor model Galaxy phones at the mall, and they actually had worse off-axis blue shift. Not sure if that's because of the initial screen quality, or that it got worse over time.
Does anyone know of any AMOLED phone (specific model) that does not have any perceptible shift? Does anyone know if the shift gets worse over time?

I believe others are correct that it is the cheap screen protector. Plastics is refracting the light leaving the phone. Since blue light refracts more (the reason the sky and sea is blue). you will then to get more blue especially at certain angles.
I don't think tempered glass of the same thickness will make a significant difference but i do recommend getting a tempered glass protection because the cheap plastic one will surely be scratched very quickly. There a lot of things that will cause increased color shift, but I am not sure its a huge issue. I don't think accurate color is needed off axis. I could be wrong. I typically only look at the screen off axis when I am trying to take a odd angle picture or too lazy to move when I am in bed.
If any one does find a screen protector that distorts less please let us know.

The first thing I did was remove the screen protector, and I still notice a blue-ish shift at angles. It's minor though, and it's definitely not a dealbreaker.

AMOLED screens are typically like that. When I get on the bus and see people using their galaxies, it always looks cyan from an angle. LCD technology loses contrast at angles, whereas AMOLED has chroma shift.

Just to be clear - the color shift happens without any additional protector. Someone else used the word "protector," but I only have the bare Gorilla Glass in front of the AMOLED screen, no plastic or other layer added.
I see it as well with no screen protector on.

I never understood why phone makers use glass. Just make it plastic with a removable glass screen protector that the user can replace if broken. My GF dropped her phone, The tempered glass protector broke but protected the glass screen.
I do like that the S7 active has a plastic screen just wish all companies did this.
Hello,
I have the same issue with 5 devices I was testing. Every Axon 7 had the issue with the color shift from a red tint, to a blue tint when tilted.
Is there someone without the issue or is it really normal?

I guess it's the pentile arrangement, since blue subpixels are larger

Aftermarket LCD Frequent Bootlooping (STOCK FW)

So I purchased an aftermarket LCD for an S5 I have here. It's for my mother so she wouldn't even notice the difference between AMOLED and LCD once it works. I'm having a problem though that with the new screen the phone keeps hanging on the screen with the Samsung logo and restarting. It can do this multiple times before finally booting whereas with the original broken screen it works first time. Has anyone had a problem like this before and if I was to even use a custom rom should that help? As I said once the phone works that's all she'll care about really.
Did you REALLY think Samsung endorses the use of LCDs? They need a driver, which the ROM doesn't have. All it has are the drivers for the AMOLED panel and the touchscreen IC. LCDs need a separate driver, but the AMOLED LEDs operate independently. Do yourself a favour and get an ORIGINAL AMOLED panel, not some cheap a** chinese clones.
Dude, if you have the money to buy an expensive phone, it's automatically implied that you have the money to service it. You buy phone with AMOLED screen, you pay for the AMOLED screen. Why do you think iPhone screen repairs are so cheap? LCDs are dirt cheap, and most iphone users are dumb enough to not notice the difference in quality.
I've tried an LCD marketed as "Replacement"
it had a blueish tint and no finger hover would work. I had to send it back because of the cheapness. Spend some more 30s and get an original service pack, which also has an already glued double sided tape (which originally as it is, it starts to peel off on my phone)
Yeah that was a dumb idea but in the title he had it listed as amoled. She wouldn't really notice though and I can pay 180 to cex for a working s5 or else 120 for an amoled screen so it's probably better to just get the whole phone which includes a charger too lol.
