[Defective Device] Screen is blur all of a sudden!

I pre-ordered my S7 edge (SM-G935FD) and was using it moderately (as a normal user generally does). Everything was quite normal and I didn't tweak any of its settings. I didn't even try out any graphic intensive games on it. But on the 20th day of its usage, I noticed a slight tinge of discoloration on the screen, appearing as if screen burn-in had ocurred. I tried factory reset and the situation worsened after 22nd day. The whole screen went greenish! I don't know if it's related to "Always On" feature but I can presume that as the only reason for the sudden burn-in. Hopefully, I was able to replace it with a new one as it was under 30 days replacement guarantee.

I want to know if anyone has any other reason for screen burn-in to happen. FYI, the phone was never dropped, pressed on screen, rooted nor tweaked any other display settings in developer options.

You just got a defective unit, doesn't have anything to do with AOD.

if it was, more people would say this, and the AOD jumps around the screen to prevent the burn-in

Nothing to do with AOD at all

I agree with you, but why did it happen all of a sudden on 20th day of its usage?
All I can assume is that pre-order lots are quite low graded!

Definitely not AOD related.

That is definitely not related to AOD. This is a hardware fault. You'll need to return it for warranty repair.

Every company has these issues, you have to realise this phone was manufactured in millions and accidents can happen. I got a black phone first and later switched to gold simply because I preferred the color, both phones were perfectly working. And AOD definitely is not causing this, you can use the feature without worrying.

like everybody else is saying. nothing to do with AOD. this can happen to everyone. don`t even think its a burn-in, seems like parts of the screen is dying(as for the curtin effect) you don`t need to worry, this prob won`t happen again

This is not even screen burn in. If it's screen burn in you can see the aod clock every time. Not these discoloration issue. You just have a faulty unit. That's all.

Thanks everyone. I'm relieved now. ?

I also had problems with my first S7e. Had a dead pixel and was not able to fix it. Changed it and now everything is ok.
To generally say preorders had lower quality is wrong i would say. At the moment it seems to be obly a few devices and compared to the order volume its normal to have a few problems with some small amount of devices. So please change the header or let delete it as it might be confusing and fear some people without any reason.
Thanks

Exactly the same thing happened in my friend's Note5 and he got a replacement in india........it happened within 2-3 days of his purchase............criticize samsung india on their official twitter and facebook pages for deploying poor quality standards in their indian manufacturing unit,i had a terrible time finding a good black onyx device in india as two of them had dead(black) pixels in their resp display's and one had a terrible front cam ......................

You just got a lemon screen, just unlucky really. Doesn't really happen often and when it does, only a minority units (yourself etc)

Like most are saying. That doesn't look like burn in. Just a bad display. Bound to be a few. Sorry for your bad luck.

Motherboard replacement

Hi guys! Do you know where I can buy motherboard to replace the one I have in my z5 dual? It got water damaged and I sent it to the repair shop and their asking me to pay almost the same amount I paid it brand new. (Is replacing the motherboard that expensive? I'll not continue if it is...) So I'm going to try fix it myself or let someone who knows better do it while I'll buy the parts. I hope someone can help me. Thanks!

hey man, apparently my motherboard needs a replacement. I sent my Z5 E6653 to SONY but they didnt repair it due to "bend" on frame. I then sent it to a different service, they found that the Baseband IC and Antenna needs replacements, I paid the additional payment but they couldn't repair as the motherboard is broke apparently .

hi,
is there any problem with replacing the motherboard, such as the fingerprint sensor is somehow tied to the original motherboard? i'm thinking about buying a z5 with broken display on ebay and using that motherboard. thanks for any help!

Hey mate, i have the same problem, my xperia Z4 got water damaged only sony logo appears and it vibrates three times and restarts, did this same thing happened with you? Did you get the motherboard replaced?

Who ever is thinking that their motherboard is not functioning, you have to try at mobile repair shops.
Sony service center people tell you to change everything but they are wrong.
My Z5 is water damaged and Sony India wanted me to pay 25000 Indian Rupees (convert it).
I've taken my phone to mobile repair shop(Delhi) and paid 5000 rupees for repairs including screen replacement.
Ofcourse screen is not genuine but mobile is working 100%. Fingerprint etc....
If your phone is even vibrating without anything on display, it is not motherboard fault. Get your screen replaced. It will do.

Hello Guys. I too have a Sony Xperia Z5 E6653 Single sim version. I accidentally dropped my phone into water and then the screen started behaving strange. After switching off the phone to avoid damage and turned it ON after couple of days now I found my screen dead. When I touch the fingerprint sensor the phone vibrates, when I press the camera button the LED turns ON and I can hear the click sound. I couldn't put the phone in rice as I was traveling. Giving the phone to service center the technician said that the display IC is gone and he cant do anything. I took the phone to local repair shop and guy told me that display is gone and he can try replacing the display, but still not working. Is there any store in India - Mumbai where the chip level repairs are done, any hopes in resurrecting the phone?

Water demaged

I dropped my Sony Xperia xa in Water 10 days ago, now it switches on, but shows a blurry screen.please help me and how can i fix it?

Display Issue on two Note 20 Ultra

I bought myself a Note 20 Ultra Snapdragon Version (Hong Kong Version). After around 2 weeks right we’re the proximity sensor is, a dark discoloration started to appear. It’s not super good visible, but still it was there. I tried to overlook it but couldn’t. So i started a repair/exchange process. After a huge war to get a perfect device the shop where i bought the mobile exchanged it with a new one. But again after 1 week this weird dark spot started to appear. Sometimes the splotch is faintly visible, sometimes he is very visible. Now i have payed 1300 Dollars but can’t have a perfect display. Anyone having the same issue?

Ask yourself , what rogue apps are you heavily using that cause this issue. These things normally occur during using VoIP apps on high brightness with screen left ON for long durations. Heat , bright screen and VoIP apps that use the proximity sensor continuously degrade it.

First i use the mobile on very low brightness since i got it. Secondly i used nothing like the apps you described. So i can’t see how i caused this. And I’m not the only one. There are other cases with exactly the same issue. It’s a design flaw.

I forgot to mention that i carefully checked the battery temperature and cpu temperature all the time to avoid unnecessary strain on the display and the internals. But still after a short time on both mobiles the same issue.

Lol i own the mobile max 2 weeks. In this two weeks i watched videos. I used whatsapp for texting (maybe 2-3 phone calls). I used a video player to watch download videos, but i used nothing that would have left the display on for a long time with the proximity sensor working. I used the phone more for media, because i still own my iPhone 11 pro max for phone calls and alike. Hence i can’t explain why this is happening. I’m the first one who would say yeah i used the apps you mentioned on high brightness all the time, but that’s not the case.

Btw your sarcastic questions are unnecessary. If you think your clever and everyone else is a moron, nice for you. But the Note 20 Ultra is not my first mobile, and i know what to avoid, and what to do in most cases. But when i get the same issue two times in less than 2 weeks without doing anything maybe causing this, i think it’s ok to ask if anyone else is having the same issue.

No worries bubba. I hope you find an amicable solution soon.

Yeah every n20u has it. Some people just don't have the eyes to see it or choose not to / conditioned to ignore it.
I can see it on demand but I forgot it was even there till this thread. No way around it, it's a design flaw of this generation.
My n10+ isn't visible unless it's being used but what can we do, Nothing.

My US Note 20 Ultra has that as well. I didn't notice it for 3 months, then there it was. It is from the proximity sensor, and it's only visible in dark environments, and on days when I've had long calls. Other times, it's not visible at all and I'm guessing the sensor is under the screen and that the visible flashing causes it to slightly offset the AMOLED pixels. Every Note 20 Ultra I've seen also has image retention issue (not to the point of burn in) but high contrast images fade off the screen for about 5-10 seconds and this is only visible on gray backgrounds. Looking for a "perfect" one may be a waste of time.

Go to system settings>display, see if you have a setting called "Accidental Touch Protection" and if it is enabled. That feature could be activating and then freezing the screen when you try to turn it back on.

Hi there! What was the answer or Solution by technicians? Did they solved the problem?

Hi all there! As I see this issue is the same that A52 has. It's a typical factory problem that could be solved charging the main flex. That's the definitive Solution !

I have the same problem with my A72 (A725f)XID
Any solutions
I tried downgrading it didn't help
Changing the screen of flex also doesn't help
So it's a software problem
But any solutions???

I have the same problem. It seems that all A72 series are affected by this problem. The flex cable appears to be problematic. Almost every Samsung product I purchased had issues. So, never again Samsung.

Sorry for late reply for all questions above. My A72 was not even a year old it was sended to numerous shops from Samsung to the cheap Pakistani shops and it is Un repairable they said that there might Me a chance to repair it if I replace the main board but to find one is very scarce and a new one is almost the price of a new device.
To me personally I will never get a Samsung again my next upgrade will be Huawei,Google pixel or a Xiaomi or anything else I do think that the better devices like Samsung galaxy S22,S21FE and Z fold won't have problems like the A72 or A52 or there was just a big bach of manufacturing that went wrong.
But do let me know if you guys got it fixed in any way maybe I can have a try to fix mine then but to replace part for part and hope that it will be fixed is a expensive route to go.

No just make sure your next samsung is from the European or North /South american market
Then you won't have no issues
I use The A53 & A52s 5G now & i don't have problems

I ordered a new main flat cable, and it was supposed to be delivered yesterday, but stupid NordPost in Norway did not deliver it in time. So, I must wait until Monday or Tuesday to get it. Basically, my phone has been opened and lying since Wednesday. I will update you, when I replace the cable. In any case, original main cable in Norway is very inexpensive. It cost me 110 nok or 11 euros.

You are lucky it is not expensive here in South Africa every thing is expensive if I take a guess it will be around R400, my phone acted actually weird because it started to have unresponsive screen restarted the device then will work for a few seconds then will have the same problem, sometimes my network signal will totally disappear and there will be two round sircles, sometimes when I charge my device it will show the phone is overheating even though the device was not even on for a while other times it will show the charging port is wet I can't think that the flex cable will cause all that problems
