Hey Guys,
My release edition S7 Edge started acting up last Sunday. As I was using the phone, it noticed the display to have strange, colored barcodes appearing as smudges on the screen. Pink/purple seems to be the dominant color type and they are most severe when texts are displayed on screen. The phone seems to get hot quicker than normal, and gets hotter than normal when under toll. The screen usually DOES NOT TURN ON AT ALL when the phone is warm/hot. Everything about the phone still works, all functions work.
It has been a few days since I encountered this issue and it has not subsided. What I did noticed is that if the phone was hot and the screen does not turn on, I could cool down the phone externally via air conditioning vents and it would turn back on when its cool enough. The barcode artifacts are also less prevalent, to non-existent when the phone is cold to touch.
I initially thought this to be an display panel issue that needs replacing. Out of warranty repairs is going to be about CAD $340. With the cooling down work around, I am hoping it may be a less expensive to fix issue.
What do you guys think? Help me out!
TL;DR. Phone started having pink and purple barcodes all of a sudden. Works perfectly with the barcode. Display wont turn on when warm/hot. Everything is back to normal if the phone is cool/cold to touch, until it starts warming up due to usage.

Hey all,
I was turning my screen off last night before heading to bed when I noticed that I could still see the picture frame widget while I was stood under my bedroom light....it looked like it had burnt onto the screen as you could only see it faintly while direct light. I then turned it on and off again and the picture frame widget disappeared but area in the top right hand corner of the screen could now be visable again under direct light. I flicked the phone on and off again a couple more times and eventually it was completely blank.....anyone else experienced this? Is my handset faulty or is this just a characteristic of mini TFT screen? I know it hasn't actually burnt the image on the screen as I don't leave the screen on long enough for it to occur and its not just residual light as it doesn't fade, but it will go completely blank after a couple more on and off's.
Strange one,I will try and reproduce it when it is dark tonight
Sent from my Dell Streak using XDA App
wiki term called "Image persistence"
might help u
Aaahhhh...thanks dead101, so just a characteristic of LCD screens....had me worried for a bit!
haven't checked out that terminology yet, but i am pretty sure that LCDs do not have the burn in effect in the way that the old CRTs did.
I've noticed this phenomenon as well, and haven't noticed it on any other device. It always goes away if I press on and off again. I don't know that it is image persistence, because that seems to require leaving it off for a period of several hours to remove the effect, not switching it back on and off quickly.
I'm worried it may actually be a fault where the screen sometimes won't switch off completely. One night, my Streak went from full charge to dead in about 8 hours while on aeroplane mode. Could be unrelated, or could be that the screen was still drawing a current. Who knows... it never happened again. Annoyingly I could not get the "what's been using my battery."
Either way, whenever I notice that part of the screen is still visible after putting it on standby, I always switch on and off to clear it.
Hi everyone,
I might have broken the screen on my HTC magic (sapphire) but i'm not completely sure. The screen does not show any signs of cracking, however shows a static screen of red green and blue horizontal lines (ill provide a picture). It is clear the phone still boots as it responds to touch (the vibrator goes off when I tap what would normally be my lock screen). Interestingly, the phone battery drains almost instantly (within 30 seconds) from a full charge and the processor gets warm, however, if I disconnect the screen it will remain on for a normal amount of time (vibrates, so I know it actually turned on, but no red light indicates battery is low).
So can anyone provide a diagnosis and possibly how I might be able to fix it? I appreciate any help.
Thank you.
I am not sure about your symptom. However, I found my htc magic had a vertical line last year but display ,multitouch, everything work fine. Luckily, it was in warranty, after I sent to the htc service center, they replaced my screen and the problem gone.
Thanks for the reply, did your screen look like the photo I provided of mine?, or was it just a single line through? I had a look on ebay, screens are only about $30 and by the look of things, not too hard to fit. However I am a bit hesitant as I cant be sure that the screen is the problem, because there's no signs of cracking, its just perfectly straight red green and blue bars vertically down the screen, which seems to me (i am far from an expert) like the screen isn't broken, the signal going to the screen is, also and it seems weird that the screen would cause the processor to heat up so much and drain the battery so fast. Anyone else with any ideas?
Just picked up my nexus 4 off the desk and turned the display on and it's started flickering.
It's like someones dropped the refresh rate really low on a PC monitor, but only when looking at it head on, if i tilt it and look at an angle the flickering stops.
Anyone else had this problem?
*EDIT*
Powered it down for a couple minutes and it's stopped flickering when i turned it back on, strange bug?
I first turned it off and back on within 20 seconds and didn't fix it, leaving it off longer seems to have resolved the problem.
Hope it's not going to become a problem.

Mine did this too... I turn the phone off for a few hours, seemed to of fixed it. Easy enough for a calibration or voltmeter to get out of wack and needed to be reset.
i had this problem, other having this problem.
I thought it reacted to me putting pressure on the sides and back, like a slight bending action to the phone ( am abusing the phone i mean like with baby hands)
So I am afraid it seems like hardware, i will get replace or maybe a refund but I will have to buy a new phone, this is a gong show so far, I am not waiting long for another one ... screw it.
My replacement N4 has the same issue, but permanently.
When the screen is cold, colors are washed out and I get that "low refresh rate" flickering everywhere.
However, when I run CF-Bench 1-2 times and the phone gets a little hot, the flickering goes away and colors are much better - until it's cold again.
Definitely a hardware issue and I'll get it replaced again (it also has a bad/crackling earphone that sounds like the grate in front of it isn't perforated).
SO Sunday morning I wake up and my phone has been on charge all night, its 100%, I unplug the phone and about 10 minutes later its very hot and at around 60% battery. So to stop this I go to turn it off and start seeing these red "bubbles" under the screen like water but its the LEDs turning red. I have never dropped the phone or put it under water. Its a hot day as it is and about 5 hours later I turn the phone back on and its fine for around 15 minutes watching youtube videos, it then starts flashing black, like the whole screen shuts off for half a second and comes back, still sound playing, about 5 minutes later the phone starts glitching out and the pixels on the right hand side start turning red (no link) like so. Then the phone starts jumping between that and this ( no link ) which happened for around a minute and since then the phone screen is just black and doesnt display anything but the phone is still active and had feedback on the screen such as touch vibrations. Really want to know whats happened and why if anyone can help
Probably a hardware defect that will be covered under warranty. But possibly a software problem that's causing the cpu and gpu to run really hot. You can try booting into safe mode to see if that makes a difference:
Shut the phone off and let it cool down.
Boot into safe mode: https://www.google.com/search?q=gal...rome..69i57.3932j0j7&sourceid=chrome&ie=UTF-8
Use the phone for a while, and see if the problem reoccurs. (Your 3rd party apps will be disabled, so you won't be able to use them, but you can do other things.)
If this seems to solve the problem, delete any recently installed apps, or factory reset the phone, and see if the problem stays resolved. If so, add your apps back in a few at a time, so if the problem reoccurs you'll have an idea what caused it.
If none of this solves the issue, it's a hardware problem.
My wife had EXACT same problem. Backup everything while you can as my wife's phone died few hours later. (no display at ALL - digitizer was working fine though - so could shut down, etc). Symptom also was that when you reboot, it will display the boot up screen just fine, but as soon as all white screen was able to display, display will just die, etc. Pressing power button repeatedly would eventually turn on the screen but color would be off and simmering, etc.
My galaxy s5 started acting up a month ago. The screen will flicker green/yellow then go black, or stay black entirely. It got a lot worse recently where it will only work hitting the power button 1% of the time. Is this a hardware issue? Or software?
When the screen dims before sleep, it spazzes out too. I've noticed it works better when it warms up from charging too. But still fails to display way too much. It still registers touch when black. I replace the battery a few months ago BTW.
If the device has no hope, can you guys reccomend a good cheap phone?
Put your phone on max brightness & set your phone to never turn the screen off
Leave your phone screen turned on with max brightness for a at least a few hours
If that doesn't solve it then you may need a new screen - it is a hardware fault on these devices with these types of screens
If I were you I'd also follow the advice of
TheFixItMan said:
. I'd make sure to run a slideshow in your gallery while having your screen at max brightness though as this may reduce the risk of having burn-in on your screen.
If all fails you could buy a new display for your S5. I did so myself recently as I kept having "snowstorms" on my display when I turned my phone/ the screen on. Worked for me, managed to get a new and genuine one from a reputable seller on eBay. Hope you won't have to resort to the latter though.

@TheFixItMan thanks for the advice, I tried it last night, and it didn't improve at all. Is there any possibility that the device isn't giving the screen enough power? Because I have better success when its plugged in. What do you think caused this to happen after 5 years?
@James160103 Thanks, I tried it and it didn't work. I'm exploring all my options. For $10 more then an OEM gs5 screen, I can get a gs7.
Perhaps it's got something to do with your new battery then, did you buy a genuine Samsung battery? How about sticking the old one back in and seeing if that makes a difference?
Also try using a genuine Samsung power adapter and charging cable.
It's worth a try anyway. Let me know if that made a change.
If it doesn't help you could remove the screen from the phone and press the flex cable from the digitizer downwards to see if it might be a loose connection between the motherboard and the screen that's causing the problem. I'd try that as a last resort though as you could damage your display in the process (replaced the screen myself and managed not to break anything, did it for the first time). There's lots of videos on YouTube (I recommend JerryRigEverything) that could help you out.
While this is unlikely, you may want to try before buying an S7.
Also, try booting into TWRP and playing around with the brightness settings and turning the display on and off again to see if it's some bug with the OS (again, unlikely but it's worth trying).
Please let me know if any of the oprions worked for you or made a difference, cheers.
@James160103 my old battery can't hold a charge, so I disposed of it. My new one has been fine for a few months without any problems. As far as a charger, I have a better charger then the stock, and a thick gauge nylon wrapped cord, that's been doing fine for the last 2-3 years.
The whole display issue isn't just on the OS, when I boot normal or into recovery it stays black, or flickers for a split second.
I did notice that if I hold it in front of my car vent, with full heat. Once its warm it seems to work, just until it cools off. I'm guessing its a hardware issue at this point, but I'll try to check the connection.
Thanks for your help
Facing this exact issue. It has gotten worse now.
