If it's a dead pixel, no. If it's a stuck pixel...maybe. The difference is a dead pixel will show up as a black dot. No color/light is displayed. A stuck pixel will always be displayed as either a red/blue/green dot. It's stuck in a certain state.
A dead pixel is not fixable...you need to RMA the device to get the screen replaced.
For a stuck pixel, you can try to find an app or video that will flash solid colors 1 at a time, over the entire screen in rapid/varied succession. This is not guaranteed to work, but sometimes the rapid color changing can get the pixel out of it's stuck state.

There are only a blue screen

In some cases a blue screen means kernel issue, you can try reflashing with KDZ following the instructions here http://forum.xda-developers.com/showthread.php?t=2785089 to see if that solves your situation

Is my 1+3 dead!?

Hi everyone,
I'm experiencing pretty silly situation with my phone.
So the story begins here:
I was surfing the web while listening to music in the bus when suddenly my oneplus3 randomly turned off and I couldn't turn it back on. (I was on something around 15% on battery so it's not a low battery problem) I tried to turn it on several times and after holding the power button for like 10secs it turned on, and after pressing the power button again (because I needed to get past unlocked bootloader screen and dm-verity) I saw a boot screen. The capacitive button leds turned on and after 3 secs it turned off again, so I started worrying... After a while I tried to access the recovery, but no luck at all. It powers it self off after bootscreen. So I started to research. Tried to flash the entire OS, partritions with msmdownload tool. After several unsuccessful flashes (firehosewritedata failed sometimes while writing userimg or system.img or boot.img) I did get the download complete green text message, and after successful flash, the white LED turned on, even the phone was not plugged in USB or charger and turned off. The screen is completely black and the white led just flashes constantly without blinking or anything. I could only turn the led off by pressing the power button for another 10 secs. And after turning the phone off, problem still remains. After oneplus logo phone shuts down...
I can access bootloader.
And after flashing everything should be on stock, because now I only got screen only about bootloader, no dm-verity..
And of course - I still cannot access the recovery.
p.s. I tried to do the power cycle (as the tech support told me) but still no luck at all.

did u tried the full msmdownload tool (1gb) or the 55mb version ?

Of course. Everything is done right. I also get that green "download complete" message.
p.s I also opened the phone. water indicators are fine and no major defects what can i see by eye... All connectors are good as well.

And yes, phone was connected right. :good: installed drivers with test mode on Win10 and got Snapdragon device in COM devices. As well the MsmDownload tool shows up my device in port #20

Any ideas?

Follow method 2 from the Hard Brick guide by Naman Bhalla and try two or three times.
Sometimes it takes more than once for restoration.

Since you opened the phone, i think your warranty is gone now.
If the msmdownloadtool didnt help you, there is nothing you can do i think.

try to flash again, and if it still maybe something short inside.
if you have disassembly your phone, try disconnecting various flex cable like camera, sim slot etc that connect to the mainboard, that doesn't prevent device from powered on, then try to turning it on.
if it still, check your mainboard, if you don't know how, send it back.

Is ir really gone? There is a still warranty void sticker on the screw there, but of course it's possible to see by eye that the phone has been opened.
I have an appointment with Level2 tech support @oneplus, they are going to remotely flash the entire OS, but do you think they are using pretty similar technique as the msmdownloadtool?

They are doing the same thing like you did.
I already had a session since i thought they are going to do something "special"
You can try the remote session but im afraid that wont help you if you already did it multiple times.

What about battery? Charged?

Yes battery is charged of course. It's just doint the same thing. Turns on, after a while when bootscreen comes it just turns off and white notification led appears, after that nothing.

I tried to flash it with tool using method 2 for like 15 times with "download complete" messages, but still no luck at all. Tried to erase partritions with fastboot, flashing just only recovery, modded recovery etc. but I still cannot access the recovery nor system. I just don't get it why the phone does not boot into recovery if I flash it or boot it straight away, It just only turns off and that's it. nothing more. Only black screen and white led lighting all the time (after a while the phone turns warm).
I have read all the MsmDownloadTool thread in "Mega Unbrick thread" and saw that few people have experienced the very same situation as me, so I was wondering if there is any fix for this? It's so strange that I was just surfing the Web and it just turned off by it self with like static image for miliseconds and after that just black screen.
There should be any fix. I guess that it's just a partition error...

Ok, not good news. I had a little remote session before a while. They says it's already a hardware problem.

Pfffft you think manufacturers notice when you take apart phones? Hell I took apart my Xperia Z2 because it was having problems and then glued it back together with cyanoacrylate hahahaha (worst thing to do but wtv) and no one noticed though it was seemless and everything looked perfect

Guys, I've got something for you! Not really the same thing as Naman.
p.s. not saying its original hehehehe keep safe

man i got a very similiar problem but my op3 has a black screen i was also on low battery around 5-15% when my phone went off after i was in twrp

Actually I was on twrp too! Also I have recently noticed that recovery loading speed was far too long than normal one. I'm talking for something about 5-7 minutes after reboot into twrp. So, who knows what did happen. Just made an RMA request. Will see how it goes.
Anyway, I was on stock 7.1.1 and it's just rooted with custom recovery and that's it! Nothing more! Is that just a factory failure or maybe it's caused by drops i have had? Nothing serious for a 4-5 times for a half year. Of course I have used it even in winter when the snowflakes are coming down from the sky and little rain. Btw, these liquid indicators are white, so all safe. ::laugh:

Screen won't stay on

I've recently purchased a used Moto G5 (3gb ram version) from eBay. It's been working fine for a couple of weeks but has suddenly developed a fault, the screen will not stay on. It just constantly goes black / blank. When it boots the Moto logo is shown for about a second and then it goes off and will not come back on until I pull and replace the battery.
I know the phone is still functioning as i can hear it sat waiting at the encryption "enter PIN" prompt on boot up, it makes a click sound when briefly pressing the power button.
The only time I can get the screen to stay on is by booting to fastboot. However as soon as I try to boot system or recovery the screen goes off.
Has anyone else had this issue and is there any way to fix it?

Attached photo showing fastboot screen which is all I can get to without the screen going off...

Why don't you try a flash,as if any corrupted partition is there for screen it can get fixed, you can use Lenovo Moto smart assistant app to flash.

It is a pc application which is use to flash the firmware on your device, it will guide you how to flash the firmware.

OK thank you. Strangely enough after a full night on charge the phone is working perfectly fine this morning! However I think i'll do that firmware flash anyway just in case. Also wonder if I've got a faulty battery...

You can try a flash, but I don't think there is a battery fault, if there any, bootloader also didn't show up, so there are possible changes of corrupt firmware in you device. And did you replace the original screen with other 3rd party screen. As that is also a reason, someone was having similar issue like you but, he has got the problem after screen replacement.so if you have done a screen replacement then that can be a problem.

No it has the original screen. Bought the phone second hand though so it's fairly scratched (but not cracked).

Green dot on my a month old phone

Hello everyone as the title suggests there seems to be a green dot on my phone near middle and a little to left like a dead pixel but the problem is that it only appears on lock screen and only appears if the background is black, however as soon as i unlock it, the dot is gone like its never there in the first place and as soon as I lock the screen its back and again gone when I unlock it. So is this a software issue or a hardware issue? And if its hardware is the warranty still applicable? No changes to software has been done phone is completely original. Thank you for time.

Try this:
https://play.google.com/store/apps/details?id=com.ossibussoftware.deadpixeltest
test app and test it on black screen
If the dot is there you have dead pixel

Thank you for your reply did the test twice and couldn't find a dead pixel any where but the dot is still there in lock screen and vanishes magically as soon as i unlock it. What could be the possible problem?

May be the wallpaper

That's the problem, I've tried multiple different wallpapers, its still there. The only thing of interest I've noticed is that it appears only on wallpapers with black background and if that specific spot is black if the color is different then it doesn't appear. I've tried a wallpaper with white background and there was no sign of the dot being there.

it's not dead pixel, it's stuck pixel. Different than dead pixel, stuck pixel means your phone pixel is alive not dead but stuck on 1 color. People said it can be repaired by using application that repeatedly changing color of your screen. So it can be repaired, but I can give no promise that you will succeed, but you can try it.

Thanks you for your reply, I'll try that the only thing bothering me is that its only on lock screen it vanishes as soon as I unlock the screen. Shouldn't this be in home screen as well if its a stuck pixel? as the wallpaper is exactly the same?

A picture of your phone display with the green dot would be good for anyone to help you. Try to share if you can.

I've tried a lot to capture it on the camera of iPhone x but cant as its the size is of a tip of the needle and its mostly visible on the lowest possible brightness it fades as i increase the brightness but its still there and completely disappears as soon as i unlock it. I'll try again tomorrow hopefully I'll be able to catch it.

After you unlock it the background image is also totally black?
Try using a totally black image on bot the lockscreen and home screen and check if it also happens.

Yes the image is totally black and I've tried a completely black image as wallpaper as well, It still happens the dot is there on lock screen and poof gone as soon as I unlock it like it was never there in the first place. What do you think is this a software issue or a hardware? Should I wait till Android 10 is released to see it goes after that or should I claim my warranty right now?

I think you should take it to a Samsung service centre first if there is one near you if not, may as well do a warranty complaint since it's an issue with the device.

Thank you for your reply and apologies for my late reply got busy with my uni so didn't had much time for other stuff. Just wanted to add during this period I found a way to make the dot go away and that was by removing the fingerprint security for some reason it went away like it was never there lol. This is one strange phone. I'll take it to a service center after this semester cant manage to make time to take it to one and it still has 8 months of warranty left..
