Stuck pixels at 60hz and not at 120hz - General Questions and Answers

Hi I baught a Galaxy A52s 5G two days ago and I noticed after switching to 60fps from 120fps that 2 pink stuck pixel appear in top left area of my screen. When I turn the refresh rate to 120 the pink pixel color disappears (they works normally). Any game running at 60hz also shows these pixels. Last time I was playing a new stuck pixel appeared, this time its color is cyan, when I looked at the pink pixel that gets stuck i found out that it started working normally, and after 1 minute the cyan one disappeared and the pink reappeared again. After inspecting using a white image i noticed another light blue one at the top too. When I play Genshin Impact it annoys me sinse I have never had this issue with my previous galaxy phones. I'm asking now if there is a fix to this. Thank you to anyone who will reply to me.

Try clearing the system cache.
Try a hard reboot.
Try it in safe mode.
Test the display with ScreenTest.
Factory reset, test before loading 3rd party apps.
However it sound like a defective display matrix or mobo. Return it if you can't resolve the issue.

The first three did nothing. the display test in 60hz shows the defect pixels while the same test in 120hz does not show any.
Does this mean that its definitely a hardware failure ? i hope that its only a software issue. I used the samsung members to report the error, I dont know if they wilp ever reply, I reported yesterday night.
The defect pixels are visible as soon qs I click on the 60hz and hit ok in Display settings, and they magically disappear after selecting 120hz and hiting ok.
Edit: knowing the samsung service in my country i'm almost certain that they will just mock me and laugh about this as its not really visible unless you really look for it.

I'm leaning more towards it being hardware than firmware in this case.
Samsung has had a lot of issues with their variable refresh rate displays.
I would really make the seller eat this one.
Your call.

Thank you for your replies. I wish i could make them change the phone but i'm certain they wont. I read in many posts of people who encountred the same issue, and even if they accept to replace the screen I know that the people who do repairs at samsung are really bad and dont care about scratching your phone or using visible glue to assemble it, I had an experience with A20 which had its fast charging broken and only charged at 5w, they replaced the bottom piece that houses the usb port but the back was very scratched and you can see the glue used, and I wasn't even sure if its really mine or someone else's phone as they factory reset it before working on hardware stuff. Let alone the time they need to get the part and fix it.
I'll just hope that they'll fix it, a friend of mine told that screen hardware defects can be corrected by software, bit if it was hpu defect i dont think there is mush they can do.
Anyway thank you for your replies its really appreciated.

I would do a refund for cash. Not sure what consumer rights you have in your country.
In the US I can right the defective product and if a MC or Visa was used the bank can do a charge back to the merchant for a full refund.
I think it's a matrix failure, a capacitor(s) or thin-film transistor(s). It could be the OLED pixels themselves. They are very complex displays.

Can software really fix a stuck pixel?

I just got a replacement Nexus 5 which is fine except for 1 stuck green pixel just about at the centre of the screen. It's a bit annoying. I don't know if they would send me a new phone over this or if it's worth the hassle.
There are a number of apps that claim to fix stuck pixels by cycling through colours. I've tried a few for a few minutes. People in the comments have said running it overnight fixed their stuck pixels.
Does this really work? What's the principle that would allow a stuck pixel to become unstuck?
If I want to try this should the screen be set to maximum brightness or not? I'm a little concerned that leaving the phone plugged in with the screen on at max brightness may cause damage to the phone or screen due to overheating. Is this something I should be worried about?
Thanks.

Usualy its hardware (screen itself) related so software cannot fix that.
No. In answer to your question

So what's going on with people who claim it's worked for them?
In any case, I think I'll call Google and see if I can get another replacement. Maybe third time will be the charm...
Because it can work.
Think of each pixel as 3 switches.
One red. One blue. B one green.
In your case one pixel has the green switch stuck on.
These apps are designed to force the switches to keep turning on and off.
Sometimes you can get lucky and the switch will eventually free itself after so many tries.
Sometimes it will not work no matter what.
These apps just try to get it unstuck.
Sometimes it works. Sometimes it doesn't

[Q] Battery gets hot, screen flickers and dies?

Hi,
I have a Galaxy Note Pro 12.2 and the battery gets really hot and then the screen starts flickering and eventually goes out. I was wondering if anyone else has had or heard of this issue?
Thank you, Snow
While doing what sort of activity at what brightness level? There is s flickering issue that isn't necessarily related to heat which is why I'm asking. .
Sent from my SM-P900 using Tapatalk
These things are rated save to use up to 80ºC, so unless it reaches near-melting temperatures, something else is probably wrong.
There are a couple of threads on screen flickering issues. Primarily concentrated issue on the WiFi and AT&T models.
It has also become a bit of a trend for people to say 'It gets really scalding hot', whilst it turns out to only be around 40ºC. That is not hot. That's normal for a device with a powerhouse CPU and no fans.
Use CPU-Z to get the actual battery temp. 25-45C is perfectly normal, 50-60C in heavy usage is also normal (Games, for instance).
This primarily happens when playing games or watching video's on it. It seems like the processor/battery gets hot and then all of a sudden the screen starts going crazy.
Enable developer options and disable hardware overlays within there. It has been said that this should fix the flickering in video playback.
Be aware that when you reboot the tablet you will have to disable hardware overlays again.
If you're rooted and have TWRP, clearing cache and dalvic will resolve the flickering for a period of time (days) without having to dive into developer options.

Hi IbrahimGla,
Once the hardware overlay issue was mentioned, I looked for instructions on how to turn hardware overlays off on the Galaxy tab (Which where hard to find). Here are the instructions and so far, it looks like it is working for me:
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
To fix flickering in video:
Enable developer options in settings (go to about device and tap Build Number 7+ times).
In developer options, under hardware-accelerated rendering, check "turn off hardware overlays". You can also check "force GPU rendering", but I've found the former is all that's necessary.

Thanks for your reply , i did what u have mentioned in the begening of my problem and no thing has changed , now after a month from the first time where my screen starts flickring the device is not turning on it is like a device with no battery it just show me the battery charging when it's off.
do you advise me to buy a new battery and replace my note pro battery??
Thank you & sorry for my bad english
I am having a similar problem with my Note Pro. It ussualy starts when the battery is down to 60%. The screen starts flickering and then I get a message saying the SD card is corrupt or not formatted. Sometimes it locks up as well. Sometimes when I plug the charger in to tells me "charging is suspended due to high battery temp.". The device is warm but not extreamly hot. If I turn the device off and let it charge, once the battery charge comes up to 70% I can turn it back on and everything works fine. As long as I keep it charged to over 60 - 70% I never have a problem. I tried several different SD cards but that doesn't seem to be the problem.
I have contacted Samsung but the only response I have gotten from them is "have you done a factory reset?".
Not sure what to try next. Anyone have any suggestions?
Sent from my SAMSUNG-SGH-I467 using Tapatalk
Sorry I missed this, I am not on here very often, I am back because the Note 7 is coming out. I have never replaced the battery on mine, so I am not sure. Apparently replacing the battery has worked for some people. I ended up sending the Note Pro to Samsung 2 times under warranty and the problem was not fixed.
Finally I called their support back a 3rd time near the end of the warranty period and said: Listen, I have send this *** to your repair department 2 times already. I want one that actually works sent back to me. They sent me a Note Pro in an un-marked (maybe a re-furb box?) with some sort of bar code sticker on the back of it.
Since then, this different Note Pro has worked for the most part, but every so often it has minor issues with it getting hot and the battery loosing charge, but it is not as bad as the one I bought. I really think Samsung dropped the ball on that tablet and they are lucky I just got a Tab E.
Definitely not my experience with the Note Pro. Mine has been rock solid for 2 years now, I still rack up a minimum of 2 hours of screen on time per day 7 days a week, and quite often more than that.
Just an FYI that there has been threads posted about screen flickering and battery issues that document issues with the battery connection and how to resolve them (involves opening the back and resoldering the battery terminal). Definitely something that you'd think Samsung would do but doesn't always do it . .
My tablet had the same screen flickering and getting hot problem. I solved the issue by soldering the battery connector in the motherboard. If you look at post #10 of this thread you will see a very good photo posted by Beut of the tiny black connector that seems to be failing. Other users report that the white battery connector also causes problems. In my case it was the black one, I soldered it a month ago and the problem was resolved.

Screen issue with low brightness S7 - horizontal lines interference?

Hi,
When I have low brightness the screen the screen shows black horizontal lines as if it was like an interference.. (it's very visible on 0:27 in white background)
Do not know if its a hardware or software problem but when I increase the brightness the lines disappear.
video: https://drive.google.com/open?id=0B64u8H_erzPTc3d0bHRsR3BNUms
or https://youtu.be/8Z3xWsanVLQ
It's very annoying, anyone else experienced this?
I haven't had that issue with mine. Could be software or hardware. If you really wanna make sure just do a factory reset without restoring apps and if it comes back it's a hardware problem.
Hi, anyway to backup everything so I can test ?
I'm also having this exact problem and i only received the phone today.
Mine appears to happen more significantly straight after an unlock of the phone (from the lock screen) , it does not appear to happen as frequently when the brightness is turned up fully however.
I have factory reset the phone (without restoring ANYTHING from other accounts/backups) and this has not helped. What's interesting is this is happening during the phones initial installation/setup also.... so before I've even entered any account info , i lock the screen and then unlock and i'm presented with flickering horizontal lines which remain for about 10 seconds and then the screen eventually rights itself, so this proves that it is not a user data issue.
It's also worth noting that this does not happen every time i lock and unlock. I've tried removing expandable memory, with an without charge cable , with screen brightness set to auto and off auto , taking the sim out, auto rotation on and off and none have stopped the issue. I'm going to call my provider tomorrow to see if i can get a replacement , but if thought i'd add my 2 cents

Hi
yes occasionally it happens with lock screen... and yes with max brightness it seems not happen...
Everything on my phone works perfectly, I don't have any other issues common which are reported here but this it's so annoying :s
I think it's the auto britghtness service but I don't know how to disable it.
Can you test if in VSCO app when you change filter it happens too more strongly (like it happens to me)

I've always just disabled auto brightness using the check box labelled (auto) next to the brightness slider .....?
And I've downloaded that app and yes it's also happening when i change the filters.
I've just come off the phone with my provider (vodaphone) and ordered a replacement which is free, as i only got the phone today
I haven't found any similar threads for this same problem for the S7 specifically (at the time of writing this) , but there seems to be similar issues with some nexus devices too , which also use AMOLED screens so could just be that we're the unlucky ones and have faulty devices. If your's is in warranty i would get it replace

the problem is that I 'm not already within 14 days and I did not want to be several days ( or weeks ) without S7.
How do I know if they give me a new one or try to fix this one ?
Can you show me the links with this similar problem on nexus?
what piece of hardware is faulty ?
what is for sure this is not a software issue. is it a problem of the screen or the integrated graphic chip ?

Black Stripes on the Screen
Hi All,
I have started facing the same issue for the past couple of days. When I increase the brightness to the Fullest Maximum and Tick the Auto box, then the Black stripes on the screen disappears, but if I lower the brightness then they start appearing, the more I lower the brightness the thickness of the Stripes become heavier. Please help me someone on how to fix this issue. My phone barely one moth old. Samsung Galaxy S7 Edge.

Hello,
It seems we have the same problem, I will proceed with warranty.
After a month of purchasing, the brightness sensor is failing, and the screen horizontal white lines. (Image 1)
drive.google.com/ open?id= 0B2Kw-KtTnhcSSGFraExIVEZ1Qzg
Then adjust the sensor to the maximum or minimum lines become smaller. (Image 2)
And finally if I expose the sensor in the sun or in this case to bright light (Figure 3) lines on the screen disappear.

may i know what model is your affected unit? is it s7 edge color black?
same issue here on my girlfriend's s7 edge from EE. im going now to ask for a replacement. i dont bother i have insurance but i'm still curious if it is the oled related problem or other component. in my opinion as technician it's a hardware related issue. I only think about i've never meet any software /os to have that issue ever. how can a software can do that if there are lines overthere specified for drawing certain things, the stripes/lines cannot come out of nowhere
First it was the dead pixels issue on the screen on the s7 n now the screen flickering lines on s7 edge n s7 ... These are not software bugs these are serious hardware issue very disappointing samsung shame even their gorilla glass is also a lie easily scratchable screen
Finally found a complete solution here.
Works like a charm.

Yes, I have my phone 3 years and the screen has been getting more and more dim over the last few months. The bottom 7/8s of the screen is darker thsn the top 1/8.

Green and purplish screen?

This is what my son's One Plus 7pro screen looked like one morning. No physical damage just unreadable display. I hooked up a HDMI cable to a monitor and it displays fine so it's not software. Touches are responsive and I have called customer support with no solution. I did a factory reset and it still had the issue so definitely not software related. Didn't use the phone for about three days and now it's working fine. Am I going to have this issue again? Anyone heard of this problem with a purple and greenish display?
Probably something wrong with the LCD or LCD cable
Looks like screen burn-in to me.

In that case it's probably a faulty ribbon cable or something similar, can't see much more from what info we have
(Also, do ask if he had left the display on for a long time, maybe overnight, on high brightness. If so, it's a burnt screen.)

Heya, I have the exact same issue with my One Plus 7t Pro. The screen looks exactly like that and is perfectly responsive (except the fingerprint reader can't recognise my finger) but unusable due to the discolouration. Did you ever discover what the issue was? Did you send it off for repair?

One Plus customer service said they would repair but I couldn't get a ticket created because I bought it through Sprint. Weird loop of going back and forth through both companies. I did a factory reset and the issue didn't fix but twice it fixed itself. The first didn't last too long before the problem came back. The second time it just fixed itself and has been working fine since. My son was sleeping with it at not listening to music and I think it was a heat issue. After factory resetting it and turning it off, I let it sit there for about a day then when I powered it back on, everything was fine. Has been working great ever since. I make sure he doesn't have it on his bed at night anymore. My guess is it's heat or too much pressure on the screen. No way of figuring it out. Not sure if that info will help you or not. I would contact one plus support.

Heya,
Thanks for getting back to me quickly. I also purchased through a third party, so I have contacted them regarding repairs. Did your son mention anything regarding water damage or was this not a concern? I'm feeling a little more confident that it is repairable, cause it looks pretty scary!
I thought about water damage he did have it in the bathroom while taking a hot shower.

Question Screen Flicker During Unlock

Every time I unlock my screen, whether it's with the fingerprint or pattern, the screen will flicker for half a second. Super annoying because it's a bright white flash.
It's not face unlock assistive lighting, as I've ensured that is turned off.
I've also tried every display setting possible, toggling things like vision comfort, comfort tone, refresh rates, display calibrations, changing wallpaper, and so on.
Really hoping this isn't a hardware issue because I'm also noticing my touches don't register all the time, unless I'm pressing the screen slightly harder. Not sure if it's my screen protector but I am left a bit concerned.
Any ideas? I've Googled this a bit and I've noticed others have the same issue but on OnePlus 6 devices for the most part, not the 9 series. If anyone has run into this before and knows a fix, I'd love to hear it, thanks!
That's how the fingerprint works. It increases the screen brightness to the max usually. It's the flaw of using that kind of fingerprint rather than sonic like Samsung. Believe it takes a picture of your fingerprint and compares vs ultrasonic gets a 3D image, the difference is in speed too, optical is faster, but ultrasonic technically more secure and does not rely on lightning conditions. I personally prefer the hardware on the back kind over both.

I don't remember it being this prominent on my previous OnePlus devices, though. My 8 Pro did not flicker as aggressively as this one does. It's enough for me to clearly notice it, even in brighter areas; this is why I've been left with a bit more concern than usual.
Not to mention this occurs even if I use my pattern to unlock.
Not sure. Mine does the same but doesn't bother me in the least bit. If it happened at other times other than unlock would be different story.

Any chance you could try and make a video of it happening on your device? I just want to see if it's the same thing as mine. That way, I'll have a better idea of this being a defect or normal behaviour.
I know, it's kind a big ask so no rush! If you ever have time. I can do the same if anyone needs to see what I am talking about exactly.
Update:
I've noticed the issue occurs only if the lock screen is showing. If ambient display is on and the fingerprint icon shows at the bottom then the device will unlock without flickering. The fact that it's happening only when the screen is on at the lock screen, is what's making me feel like maybe it's not a hardware problem. Very odd issue...
Another update,
After doing more Googling I came to the conclusion that it's a hardware issue over software. I tried to factory reset and the issue was still present.
I couldn't update the software on the phone though. It kept telling me that there was an installation problem. I'm guessing that's because I had previously used a rooted EU boot img and a factory reset through the phone settings isn't enough to get rid of that. I'm hoping the repair center won't fault me for sending the device back with an unlocked bootloader. Doesn't seem like OnePlus would do that anyway, given how open they are with the modding community.
Once I receive the replacement of test to see if the issue was still there and will update this thread.

Another update,
After doing more Googling I came to the conclusion that it's a hardware issue over software. I tried to factory reset and the issue was still present.
I couldn't update the software on the phone though. It kept telling me that there was an installation problem.

One time I sent them bricked device and they still accepted the return. Returning unlocked bootloader phone shouldn't be a problem.
What made you think it was hardware since I see other people have the same thing. Hell I had it too. I don't seem to have that problem after updating to latest firmware. Seems to be software to me.
Hope it gets fixed. I saw a thread for it on OnePlus community forum, so hopefully OnePlus knows.

When I sent the phone away for trade in there was no mention of rooting or bootloader unlock. Just wipe it.of your info and data.

Thinking it's hardware because my 8 Pro doesn't literally cause a white flash of the entire screen, it would just up the brightness which is normal.
And I was also noticing my touches only registered on more firm presses. Made me think it could have been a bad display panel.
Didn't want to take any chances especially while inside the 15 day return/replacement window.

Yeah good plan.
It absolutely does NOT do that on mine. Only the fingerprint area gets bright, not the entire screen.

+1 on the 9Pro
According to the OnePlus support section of the site, the progress shows as "Inspected". I assume the next step is shipping out a replacement. Hopefully it's soon, will post an update on the new unit.
Thanks for letting me know you guys aren't experiencing the issue, makes me feel good about my decision of sending it back. Almost didn't do it because I didn't want to come back to this Pixel 5 after being spoiled by that 9's screen size lol.
Got the replacement today, after some testing it seems like this unit has no issues! There is a clear difference between this one and my original. There was a blinding white flash even when using my pattern to unlock. Same thing when double tapping the lock screen to put the device to sleep.
This has no white flashes so definitely seems like a hardware issue. Finally, I can start enjoying this thing!

No it happened on any brightness. It was just more noticeable in low brightness and reading through the same issue on OP forums, others were confirming it is hardware related as a complete factory reset isn't able to resolve the issue. If it was software related, a complete restore would have/should have fixed it. Your issue might be different from what I was experiencing.
