Aftermarket LCD Frequent Bootlooping (STOCK FW) - Galaxy S 5 Q&A, Help & Troubleshooting

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.

Screen malfunction : "liquid-like" spot appears under glass screen!

I've had my Legend for two days now. I've ported all apps with AppBrain, I've restored all contacts, sms/mms/call logs and I've set it up with my Google account.
Then after I plugged it from charging today:
- I noticed a "spot" in the center of the screen.
- It has a "wobbly" edge to it (caterpillar like)
- It's darker than the rest of the screen
- There are five "spots" in a line running thru it which are as light/same color as the rest of the screen (I figure these are somehow part of the touch functionality of the screen).
- When I run my finger over it, it "moves" in fluid like motion, up and down the screen. NOT sideways.
- It's visible when screen is turned on, but there is nothing visible on the or damage to the AMOLED.
What's going on here? It's off-course never been droppen, it's brand new, it's only been out of the house ONCE for a small walk...you know the drill, it's brand new.
I figure some kind of fault in the assembly of the phone, perhaps the capacative layer is loosening from the glass or the glass is touching the amoled.
I've sent mail to the store and I'm awaiting an answer. BUT, these things can be a hassle. How should I handle this? Should I use it anymore at all?
Anyone else seen this before or on their Legend? (I've dropped my Hero several times and never seen this before).
Thx

Totally agree. I had a similar problem in a Diamond2 and the "spot" went biger and biger with months.
that depends on which country you are in, if in SG, they (HTC) will sure push it as user abuse and void warranty. So All the best
I've read far and wide about AMOLED displays and suspect that this "defect" could have been caused by water seepage.
AMOLED and water do not mix well...
AMOLED and bright sunlight also do not mix well.

Ugghh.. i think i have a stuck pixel!!

Its right at the bottom of the screen on top of the P in Phone on the HTC dock. Now i've heard that for a pixel to be stuck, it should be only one colour. But the weird thing with mine is that it appears to be a different colour depending on the angle i look at it from. It changes from green to red, and i think blue too. Is this stuck or dead, and anyone have tips to sort this?
Im kind of annoyed because my phone is only 4 days old. And i don't want to send it back because shipping could be costly and take weeks to months.
I have fixed stuck pixels in the past by pressing quite hard on the screen and "massaging" the spot. Be careful not to press to hard, but it can take quit a bit of pressure. There are several causes for stuck pixels, and this wont always work, but from what you have described, this probably will.
You may have to apply pressure slightly offset from the pixel.
Good luck!
I dont know how hard to press, im scared i could do some damage to it. The screen feels like glass so i dont think im reaching the pixel..
DO it when the screen os on, preferably with a white background. Press untill you see the colours go funny.
Its pretty sturdy dont worry too much about breaking it. I havnt actually done it with a DHD, but i have with an iPhone and a G1.
i wouldnt press on the glass lol, your risking breaking it then warranty wont be covered you might just have to either live with it, or send it back to handtec asap.
seems like you got a bad unit stuck pixel and sim gap cover, still surprising since mine is from same handtec batch as yours and its 100% perfect

No matter how hard i press, the colours dont go funny. I know what you mean by this, i have a stuck pixel on my laptop too and applying even a little pressure and the colours change because the screen isnt protected by glass, but by plastic. But doing this in the DHD is another story.
Do you have a Desire HD JamesBarnes? Could you try it yourself? Pressing on the glass until it flexes seems far too risky imo.

I think i'll live with it Im in no mood to send it back and have to wait even more.. i guess im cursed because all my gadgets get stuck pixels. My old psp, my laptop, and now my DHD.
I just tried it, and had the same result, no joy. I guess that means its well built though
See if you can find a stobe application, sometimes rapidly changing the colour can fix a stuck pixel too...
There are certain screen fixes you can run in the browser which flash the colours very fast which can unstick some pixels. I've used it before on a laptop. Just google for stuck pixel fix. Not sure if they will work with the refresh rate of a phone screen but its worth a try.
Sent from my Desire HD using XDA App
I downloaded an app called JScreenFix and let that run for 25 minutes. It changes the colours of all pixels rapidly. But still no luck.
They might not replace it if its only 1 singel pixel.
If it's anything like LCD's then they usually have a specific number of stuck/blown pixels before they accept it as faulty..
Usually around 5 - 8 pixels mark...

Correct, but it's up to the manufacturer. For example, if I remember correctly, HP requires 3+ pixels to replace.
for phones its usually a zero dead and / or stuck pixels. you will have to send htc an email asking about their dead stuck pixel policy

My Note 4 is coming and I have some questions

Hi friends, I have a Samsung Galaxy Note since 2012 and I used to love it. It was fast, big, it had a good camera, an almost perfect screen (The first HD Super Amoled screen) and the amazing S-Pen. It went from 2.3.5 Gingerbread to Android 5.0 Lollipop (Unbelievable). But yes, after 3 years of heavy using it, it started to show problems. The camera stopped working fine, It didn't focused anymore, the S-Pen started malfunctioning (moving elements of the screen without even touching it), the USB board went bad (including the microphone and usb jack) and the screen has burn-in issues. Then I assumed that was time to change it. Now I'm looking for the new flagship, the Note 4 (which I'm going to buy in January). So I read almost every review of it, every video and photos taken with his camera and everyone says that the phone is almost perfect (I mean almost because the 80% complains about the Touchwiz Layer in the OS, which I love and I don't have any problem to live with it) and doesn't have any flags. So I came here to ask to the people who already owned it and have some daily experience with the device what are their thoughts, problems and good things about it. Also some little things that I'm a bit worried:
-How good the camera is?
-It's early to ask because no one had this phone for more than 4 months, but does anyone experienced screen burn in? And how looks the screen in direct sunlight?
-What parts of the phone are metal? Only the frame or the whole body? And how feels it? It's good to handle or still feels like cheap plastic?
-What about the phone duration? Anyone had scratches on it? How bad they're? Please if you can add some photos of them, because the phone isn't even released here in Argentina and they arent any covers or protectors for the it so I need to stay for around 3 months with a "nude" phone.
Sorry for too many questions, but I really need to know how good this phone is because the price is really high. Thanks!

- The Camera is fine, in my opinion, but that probably depends on the persons preference and use.
- I can't say I have experienced any burn-in, but the screen is okay in direct sunlight; however, if you angle your phone to inspect the glass in sunlight with the screen on, I notice a reddish tint all over with that blurryness you would experience if you were in a well-lit city at night without glasses when you need them haha :silly:
- Admittedly, the phone feels a tad delicate, but that's what cases are for! I have been using an s-view case without a screen protector since purchase and it still looks like-new! If you aren't going to use a case for your phone though, a full metal body might be better.
- With my s-view case and no screen protector, my phone has no scratches - that I can see. Unless you carry your phone in the same pocket as your keys and other objects, you will be fine :3 Unless you carry sand in your pocket Phone duration seems to vary among different models though. I am using a 910V (?) and I get anywhere from 4~6 hours of Screen-on time. The stand-by time is the best part though imo. I can usually go 2 days or more without a charge.
edit:
The red tint usually happens if I angle the phone on purpose I leave my brightness settings on automatic and the screen is always clear (as it would be at nighttime) with the sun directly over me.

Thanks for the fast answer! And how do you feel using this phone? Do you have any complain or something that didn't liked about it?

If I had any complaints, the s-pen would convince me that it's worth it so I'm pretty biased xD
The phone is just fine. But u should buy the qualcom varients as this is my 3rd note 4. Its qualcom but backside 4g+ is written. Its true if u see the display from an extreme angle you will see red tint but its normal for me cause almost nobody watch the display from 170 or 180 degree. Qualcom chipset has better ram and bettery management over exinos one. And the phone really looks premium. Not only looks but u will feel it when you touch it. No problem seeing the display at direct sunlight. And it does not matter if they use gorilla glass 10 it will have scratch if you do not use screen protector or flip cover. So be careful.

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.

BSOD

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.
Replacement Screen Price As of Post:
279.94$ USD on Amazon
