Screen won't show after cracking the screen - OnePlus 3T Questions & Answers

So my phone cracked up today(rip) while I was doing some gym exercises. The phone fell from like 1.5 metter or so and the screen cracked.
The problem is that screen won't turn on, even when the phone looks like it works. I tried to furce shut down and turn it on and back and recents buttons work, but screen while stay black. What should I do? I will replace the screen but I'm not sure why screen won't show up, maybe something got disconected with the fell? Does anyone has any type of experience with this?

So, your screen is broken, and you need to have it repaired, what is the problem? Some parts still working?
Just get it fixed...

I really don't know why you asked this question, but I always try to be helpful. Since you did drop it, and from such a height (do you like keep your phone in your pocket while doing pull-ups? Mine's always in my bag and I use BT earphones).
Since your screen is cracked, and that impact could've damaged your phone in many ways.
1. You could've damaged your digitizer, which is a screen replacement situation
2. You bent a cable from your screen to something else, and that may be the issue, still would need to replace the screen.
Your buttons working have no relativity with the screen not working, it works with other hardware not interacting with your screen.
Don't go for third-party screen replacements that "fixes your digitizer seperate from the touch", it mostly doesn't work, and it'll be a waste of money, if you bought it from OP Store, just RMA it, or if you bought it from a seller in your country, just order the screen off eBay, and have it fixed. Your shop will most likely replace it with a non original screen, which will be horrible.

I think he is confused about the glass versus the AMOLED panel. A lot of times, you see folks with broken glass, but the screen still works (still displays graphics) and he is wondering why that isn't the case. At least, that is how I'm interpreting the question.
The answer is that the "screen" is composed of layers. The top layer is the glass (which for Super AMOLED also incorporates the touch panel or digitizer) and below that is the AMOLED which actually displays the graphics.
Since the glass is broken, and the AMOLED is not working, it's possible (or even likely) that the AMOLED was also broken in the impact. Yes, it's also possible that a connector has come loose. But from what I'm reading, it's actually common for the AMOLED to break before Gorilla Glass does: http://www.gophermods.com/amoled-vs-lcd-tale-two-screens/
A lot of times when you see folks with glass broken, but everything (touch and graphics) still work, it may be with LCD screens; which are supposedly more durable (more possible for glass to break before the LCD).

[Q] Replaced Nexus One screen, now the screen won't turn on

Ok, so I broke the screen on my Nexus One. These things happens. I ordered a replacement screen, and thanks to numerous online guides, I (thought I had) replaced the screen.
Now, I guess that some other parts of the phone might have become damaged, but I doubt it. The phone seems to work. The touch buttons light up. The unlock gesture gives a slight vibrate. So does the volume rocker when I (seems to) reach the top/bottom of the scale.
But the screen itself doesn't show any response. No backlight (should I be able to see that). Nothing. What could I possibly be missing, I've gone over everything three times, but can't see nothing wrong. I've checked all the connectors everywhere. Somehow I get the feeling I'm missing something obvious....
Are you sure you bought an amoled screen replacement and not the slcd screen? That would cause such an issue.
Or maybe he needs an SLCD screen and not amoled..
I was going to ask if your wifi and bluetooth still work but i suppose you cant really test that yet...
I replaced my digitizer last week and now the phone works fine apart from the Wifi, Bluetooth and the charging pins for the dock at the bottom. LAME!
Maybe two Months ago I replace the full Housing on my phone is no easy task but not too difficult either. Check if you didn't ripped any of the flex cables and if the cables are connected properly. I have a long history of replacing housings and my best advice is to do again make sure you have time.
Exactly the same issue. Did you find a solutions?
I too had a broken screen. So, I ordered one from ebay and replaced it.
Now, it screen does not turn on though the icons at the bottom of screen switch-on.
I can here the sound when volume rocker is pressed.
Also, I believe that the touch is also working as I can hear the unlock sound when I swipe my finger across the screen.
Did you find a solution to the problem? Did I make some mistake or the screen is faulty?

Just months after the Nexus One was released, Google announced that the AMOLED Company "Brightstar" fell short of displays and was unable to produce more displays for HTC, so they decided to move to Sony to make the displays, To determine whether a phone has the AMOLED or SLCD display, The internal sticker on the back side of the screen assembly can be examined; part number 60H00443-03P indicates SLCD and part number 60H00287-00P indicates AMOLED, and as i mentioned, the AMOLED screens are gone so finding a replacement for that model would be merely impossible. I was looking around and thought that i may of found a fix to this, see, the HBOOTs on the devices are both the same except the top code of the screen that determines the screen type, if you were to flash the SLCD HBOOT, you might be able to retrieve a working screen, well its probably worth the gamble anyway since you probably are not going to find a replacement in a while.
EDIT: And after moments of posting, i found a AMOLED screen seller that will ship to Europe! http://www.ebay.co.uk/itm/LCD-Scree...K_Replacement_Parts_Tools&hash=item4d06825672
Dude, I dropped my n1 and shattered the screen almost 2 years ago. Bought a replacement screen and tried to replace out on my own. Needless to say, it didn't go so well, my n1 was is a paperweight. Good luck man! I miss my working n1...

[q] how does the screen work?

my galaxy ace had dust under the screen. to remove it, i disassembled the phone. I removed the dust between the glass and the screen, assembled the phone again and booted it up. But know the phone does not respond to any touch.
to find out what the problem is i'd like to know how the screen works. I believe that when I touch the screen, this is sent from the front glass to the 'phone', which makes the screen show the according view. So when the screen does not respond to me touching the screen i'd have to look for a new glass or could there be another problem?
i''ve cleaned the screen with lcd screen cleaner (on both sides because there was a fingerprint on it on the back side). I don't know if there was some sort of layer on the glass which could be removed by this cleaner, which actually would be essential for the touch function.
i hope someone can help me. I'd like to use this ace for a longer time...

thanks! i've used that tutorial for replacing the broken screen my ace came with from my sister. I replaced it and then everything worked fine again. However ,after that screen replacement, there got dust under the screen which I tried to remove this afternoon.
The dust is gone, but the screen doens''t respond to anything now.
I'am wondering if i 'broke' the screen and I should get a replacement screen, or that i may have damaged the lcd screen (which is fine i think, it displays everthing perfectly). or maybe the glass is fine but some connector is defect (i've disassembled the phone again, checked everything and connected it again).

Xperia Z3 Compact Screen Flickering at Random

I have a D5803 that came back from being serviced. The touchscreen went bad, so the whole assembly (screen + sensor) was replaced.
Since you have to almost completely disassembly the phone to get to the screen, I suspect something went wrong during the repair.
The screen is flickering at random. By flickering, imagine a bad fluorescent lamp: you can clearly see the brightness varying vary fast, causing a flicker effect. Also, imagina a CRT screen. The flicker stops when you refresh the screen, like cycling through the home screens of your phone.
The guy who repaired it said it is a bad resistor that controls the current going to the panel's backlight. His excuse is that the board is very thin and fragile and that something might happened during the repair service. He also said that if he tries to do something else, the problem might get worse/something else might break. I suspect the screen installed is not OEM and is of bad quality. Sometimes the screen keeps autopressing as if someone was actually touching the screen, but not. Wiping the screen down on soft clothes (cleaning it) solves the problem. The screen probably doesn't have an oleophobic coating.
So, my question is: Is this guy right or is he lying (trying to push me ****ty parts/service)? How to know?
Also, is it possible to have a slightly smaller sized screen part? Because it feels that the screen area has decreased a bit (bezel increased somewhat). But since I do not use this phone since almost two years ago, I might be imagining things.

Huawei p9 black screen

Sorry if this is the wrong place to post or it's been covered already. I have a p9 stock that I changed the screen on after dropping it. Everything was fine until the new screen started to fail, it was a cheap eBay screen and the glass started peeling away. I fitted a new one and when I switched it on the backlight comes on but no image, backlight then flashes 5 times and then stays on. The phone does the one vibration like it's starting up but after that does nothing. I tried the reset procedures but doesn't help. It wasn't on USB debug so I can't connect with my pc. I first thought the screen was faulty so had the vendor replace it but still have the same problem. Could it be the main board has been damaged or the flex cable?
Sounds like a batch of bad screens. I would stay away from eBay when it comes to Huawei P9 screens, too many issues with them. Had ones that were refurbished or glass separating from the screen frame.
Buying it without the frame and applying the adhesive yourself seems to work better for me. Anyway hopefully you didn't kill the backlight circuit on your phone.

Backlight seems to be fine. You could be right, there's a faint blue tinge in one area.
Hey, did you ever solve this? I have the very same problem

Wierd issue with Nokia 8.

I only got this phone couple of days back and I am having a strange problem.
After installing a screen guard, touch stops working when phone is lying on flat surface. Once I lift the phone, touch starts working again. This happens regardless of the phone is plugged or not in a power socket.
Removing screen guard resolves this issue. However, I installed three different screen guards of glass, plastic and rubber types and with each type touch stops working on a flat surface.
I also did a factory reset but it didn't help. I tried with case on and off but the problem still persists.
At this point I am clueless how to resolve this issue as the phone doesn't seem to be defective as touch works flawlessly without a screen guard.
Same here!
With glass screen protector I have this issue... Can't really use it while device lying on a table.
Hi... Same here also... I thought the screen problem but not even lying on the table but when in charging lying on the table also can't touch... And sometimes it's stuck when to touch... My nokia 6 i think also like that... Maybe the screen curve is??
I have screen protector bought from Taobao, no such problem on my Nokia 8, TA-1004.
The screen protector is not glass type, but looks like plastic type.
Another strange observation: If I plug headphone jack when the phone is lying on flat surface, touch starts working again.
I suspect this entire thing has to do with metal/glass body of the phone and static electricity generated or magnetic field around touch panel.
I don't have much knowledge on this type of scientific stuff so I am not sure what the problem is.
It's the cheap glass protector and its glue that is messing up the touch screen.

I thought so. But what about headphone jack fixing touch issues with screen protector on?
Also, I have used similar quality screen guards on Moto and Huawei phones at my home and they don't have this issue.

Are you connecting it to headphones or speakers?
Maybe the capacitive buttons doesn't like the glue and messes up everything? You could try enabling these in the Developer Options: Show taps & Pointer location. Let me know what is happening

Headphones.
Enabled taps and pointer location. When phone is not touching a flat surface everything works fine. A curve is drawn on screen showing various gestures and a circle is drawn to show taps.
When lying on flat surface, if I use any touch gestures (e.g. scrolling) curve is drawn once in 5-6 attempts. Same with taps, circles appear only once in a while.
It is all very erratic. When I repeatedely try to tap anything, I receive ghost touces at a different part of screen.
Just noticed that I don't need headphone jack to fix touch. Blocking 3.5 mm port with one finger also works. This is truly getting weird.
Have you shown it to the Service Centre? Do they have any theories?
Sent from my Pixel 2 XL using XDA-Developers Legacy app
No, since the phone works perfectly without screen guard, I think service center guys will simply tell me to use it without a screen guard.
But I will indeed show them this problem after few days, though I am not sure they will understand or will be helpful in this regard.
I think I am reaching somewhere. The antenna reception at the top might be messing with touch.
What I have observed that touching the top of the phone or keeping any object or my hand one inch away from top of the phone fixes touch issues.
If I remove the object or move it farther than one inch, touch becomes messy again.
If I put little pressure on bottom chin of the phone, the top of the phone raises a bit so that the top antenna is not close to flat surface any more. This also fixes touch issues. Lowering top part of the phone brings back touch issues.
Anyone else with this issue can test this?
This video exactly describes my issue:
I found that many phones had these issues in past including oneplus, lg, sony and galaxy phones. Everywhere it was mentioned that it is a grounding issue which is unfortunately a hardware detect.
My phone is fortunately within replacement window. So I will contact the seller and request for a replacement.
I was thinking about the grounding, but when you mentioned you used headphones i thought it couldn't be the case.
Keep us updated if you get it replaced.
Just received the replacement. Same problem on the new one
I don't know what to do now. No other phones in my family have this problem and that includes $200 budget devices. This is flagship and much more costly.
I will just summarize different cases in which the touch issues on a flat surface gets fixed on my device:
- Inserting headphone jack (with screen gaurd applied on display).
- Inserting charging cable (with screen guard applied on display).
- Touching any part of the phone with finger including blocking the headphone jack (with screen guard applied).
- Removing the screen guard.
I am tired of this sh*t. I have tried all things possible to fix it. I have also wasted money on 6 different screen guards to fix this issue.
Some guys on galaxy s8 forums mentioned that modern curved phones uses a touchscreen placement mechanism different than traditional smartphones (they were also having the same problem).
There were two possible solutions mentioned:
Find a screen guard that has glue all over, not just around the edges or at dots. Which means that screen guard should stick to the screen 100% flat without any gap, air or bubbles.
Second solution was to use a flip cover to protect the screen and no screen guard.
I will go with second solution and buy a flip cover. I simply have no energy left to hunt for screen guards that work properly on Nokia 8. Not to say that you will never know if it works or not unless you purchase it and stick on your phone.
Hi, I'm writing from Italy and I've the same problem, exactly the same problem, solvable with the same solutions you have proposed: remove the protective film (a glass screen guard in my case).
I'm noticing that the touch screen works perfectly with the protective film only if the phone is connected via USB cable to the battery charger or to the pc.
