Weird screen flickering - Verizon Samsung Galaxy S7 Edge Questions & Answers

Hello,
This is my first post in this part of XDA.
My wife has an s7 Edge and the screen started flickering. I got out of this state messing with the power buttons etc. Mainly getting the touch screen to unlock the phone and it somehow cleared right up.
Is this a software issue? The screen when it came back is working as usual when I restarted the phone it became crap again.
Im think it maybe the lock screen causing this, I never heard of parts being corrupted.
I've attached a little clip of the screen.
Thoughts?
Thanks in advance!

I have never seen this happen before. If I were you I'd flash a new ROM on it in Odin and if it still happens take it to the Verizon store.

Forgot to mention, it's not rooted completely stock.
So screen is messed up?

I had this issue. My phone fell from less than a foot off the ground and landed on the corner. Barely any force, but after that the screen would flicker intermittently. For a day or two it would come and go, and then it became permanent. It looked exactly like yours. If your bootloader/recovery/download mode flickers then it is a hardware problem, since the ROM isn't even loaded yet. With Verizon, your phone is fully covered from manufacturing defects for one year, so you should be able to get it replaced. Sorry bro. Wish I had better news.

Honestly with a screen issue like that, I really recommend taking it to the Verizon store and asking them about it. It seems like a hardware issue to me but that's just my opinion.

My screen has done some weird things as well fresh out of the box. I would have random areas of the screen pixelize until I smack the back of the phone. Even after root It will randomly do it every other month. My father in law had the same exact issue you're having. He brought it into T-mobile where the screen literally failed and went black in the employees hand. Neither his or my phone has ever been dropped. This is definitely a hardware issue. It's almost like a bad connection between the LCD and main board. Make verizon get you a new one before the screen goes black!

Okay...
Is it okay to say I can get a new screen and do that repair myself?
I wanna make sure that the issue I am having is just "buy a new screen and be good to go".
Thanks for your time!

So i sent my nexus in for repair

it arrived yesterday at htc repair and ive been watching the repair tracking site. i had some pixel problems, like a quarter of my screen was darkened grey.
Keep in mind my phones bootloader unlocked, rooted, haha and i sent it in as is running the latest miui. Why? idno.
Anyways. I just checked the repair site and it says:
Ticket Information
Status: We are repairing your phone.
Service Type: Repair
Issue Description: top screen is darker that the rest of the device
I havent approved to pay for any repairs for an out of warranty phone. So i guess im off the hook right? I think im about to prove that htc repair people dont give a F***!
THought id share..
Uhhh, we have known this for a year now. It has been proven time and time again that HTC will warranty repair hardware defects, despite an unlocked bootloader.
This is nothing new or surprising.
Did someone has problems with the multi-touch screen: lags, do not respond or random reactions ...even when having a call ?
the solution for now is to push "shutdown button" and it seems to reinitialize the sensors for the screen ... isn't it weird ? It occurs 40% of the time ...
The menu for reinitialize sensors/calibration do not exist (for HTC Legend/Hero you can re-calibrate the sensors).
Do you have same problems ?
I will send it for repair soon...
im having the same problem, ive had it for a long time now, ive gone threw 20 Roms. so i know its not software related, or is it something the devs are over looking??
weird thing ....do Googlers have same problem when demonstrating navigation/goggles/phone calls/voice recognitions .....or do we fall on bad series ???
definitely hardware problem or something no-one has been aware of ....?

Sometimes it's worse than others, I think if the phone is running something pretty intense it happens more often. Otherwise, no, there's no calibration. Calibration doesn't make sense on a capacitive screen.
The touch screen issues have been known since the beginning, and the solution of quickly turning the screen off and on has been known for just as long.
It's part of the hardware, and most if not all Nexus owners experience it once in a while.
Getting a warranty replacement for that will not fix anything, it is a flaw in the hardware design.
Good thing to know that...but really weird for such a device...they probably think about it when starting/choosing next nexus.... ;-)

I'm curious whether they'll return it with a relocked bootloader and stock ROM
i've noticed that the only time i have touchscreen response issues is when i use my N1 without a case on it and it seems to be because some of my fingers touch or get near the edges of the screen glass. i have a silicone slip on case and when its on the phone it prevents me from touching the glass accidentally at the edges and i never experience any response problems when its on the phone. just my 2c.

yeah that would annoy the crap outta me as well, glad mine does not exhibit this problem.
i'd love to guesstimate how old mine is but i'm the second owner, it might be possible that they fixed this hardware issue in later build revisions or it could just be a random problem with the touchscreen/module, some do it and some don't idk.

was it amoled or slcd though lol
i have to make the call when i get up. today my usb port was gone from the phone when i went to plug it in tonight. i never used to have the screen issue, it slowly started happening and now it happens all the time, i lay it flat in my hand and i hit a button on screen and my menu pops up etc.
nice to see a recent time frame though, i'm dreading going without my phone and having a dumbphone replacement. would love to know if it was amoled or slcd you got back though, thats my one worry

Grey Screen (NO REACTION) - Please help me out guys

Hey guys...
So, I have my Desire Z since about 4 weeks and nothing went wrong with it.
Really NOTHING bad happened, it didn't fall on the floor, didn't fall into water, etc etc.
So this afternoon I unlocked it and suddenly I got a blank grey screen.(worked perfect in the morning) The phone did react to my power up/on button, but I couldn't see what I was doing. Also the touchscreen worked, because I could unlock it (I heard the unlock noise) but I only get a blank grey screen.
I tried Bootloader and Battery pull. Also I took out my SD/SIM/Battery and just blow through the whole phone but nothing want to happen:-(
By the way, my phone is fully rooted and running on Cyanogenmod7 since 5 days. Everything worked perfect until this afternoon...
EDIT:
Looks just like this http://i51.photobucket.com/albums/f368/forthcomingtangent/DSCI1196.jpg
C'mon guys:-(
So is it grey from bootup till it gets to the rom or can you see your boot splash screen and whatnot?

Yes, when I boot it up it's grey, I notice that it's still working because I get the bootup noise. So I can see nothing. But what I noticed is that the grey screen gets a kinda bluegrey screen while the cyanogenmod7 boot animation(the loop)
Sounds like a hardware issue to me, I'd send it in for warranty if I could. Plus, with your screen being the issue I doubt they would check for something like S-off or anything like that
sounds to me like the ribbon cable for the screen has either broken or not placed in its socket properly, does it make a difference when the keyboard is open? try opening it and closing it a few times... watch the screen. otherwise it could be a fault with the screen board or the screen itself
i would try and claim off warrenty or insurance
No it does no difference when the keybaord is open:-(
Problem at the whole thing is, that I have no warranty because I bought it at amazon.com
you either have to see how much htc will charge to repair it, or take it apart yourself and just check the cables... if any are loose then refit them... or buy a new screen, vga board and ribbon cable and fit it
How much would the last option cost?
And how much do you guys think HTC will chare to repair it?
http://cgi.ebay.co.uk/OEM-SLIDE-FLE...944?pt=LH_DefaultDomain_0&hash=item2a10708cb8
something like that if its the ribbon cable.... but that gives you the whole kit
http://cgi.ebay.co.uk/Touch-Screen-...K_Replacement_Parts_Tools&hash=item2a0fd454a5
thats the digitizer but i dont think youll need that but just in case
http://cgi.ebay.co.uk/NEW-GENUINE-H...K_Replacement_Parts_Tools&hash=item2eb3f529d0
thats the screen
but in fairness your better off taking it to a repair shop and getting a price... if you havnt got a warrenty then you dont have to worry about loosing one
Wow thanks, you're really helping me.
So I found a warranty document, since I bought it over amazon.com from another seller(mobilejoker) and it says that they'll repair me my device if it is defect and not my fault. But they also charge 40$ if it's an obvious damage made by myself. Well, I don't know, it wasn't my fault right? I mean it's not like it dropped in water or fell on the floor.
looks to me like its the ribbon cable or the vga board for the screen, as long as you havnt dropped it in liquid, on the ground or opened it up then it cant be your fault... id go with the warrenty first before you open it up
Hit the thanks button please matey
Done
And thanks again for your help.
alrite glad i could help, if you get stuck or if the warrenty doesnt work come back
hey guys I'm having a very similar issue on my phone, I bought a screen on ebay from a USA seller, as well as a flex cable cus both were damaged in my phone. I've got both of those installed and the phone boots up, gives off noises and vibrates like his did, but no video. Backlight lights up, but just black. I've been googling a lot and apparently the grey screen is just a precursor to what I have. Where exactly is the VGA board? is it on the main logic board? does it need a reflow like some laptop chipsets?
Hey guys I just thought I give you a quick update.
So I got my device back, it's working perfect and I didn't have to pay anything for it.
I'm just a bit confused, because my phone now is totally unrooted, and I always thought that root hurts your warranty.
Anyways, thanks for your help!!

Either they gave you a new phone or...
They replaced the screen (or samaged parts) and wiped or perhaps upgraded to newest stock.
Do you still have all your info and apps that were previously on it?
What version of android does it show in about, and which hboot do you have now?

Well it's just like it was when I bought it, 2.2.1, only google apps, had to configure sim again no sms, etc.. But my phone is definitely now new because there are my scratches on the back of the phone.

I didn't quite understand your reply, lol sry, but I did see one big clue....2.2.1. Which means you should have no problems rooting again.

I don't have any problems with rooting again, I was just saying that I was confused that I got my device repaired for free, although they unrooted my phone.

touch screen problems?

I have a small line on my screen that is unresponsive. It goes straight across the top of the screen exactly where the install button is in the play store (about 1" from top of screen at roughly 1/4" thick). Its in a pretty awkward spot and causes a lot of problems. For some reason it has also disabled the tap to wake feature of my phone.
I installed the "Touch Test" app which shows that my entire touch screen is working. However it shows the phone recognizing 2 pointers (touches) being active whenever I touch that area of my screen. I've been having this problem for 2 or 3 months now and all of a sudden today on my lunch break it went away. I was able to tap to wake the screen (worked perfectly the 20 or so times I attempted it), I was also able to hit the install button in the play store and life was great... Or so I thought. A few hours later on my next break my phone went back to annoying piece of junk that I completely dislike using.
Now I dont know exactly when this started happening. I did notice it sometime soon after the 4.4 update, and flashing a custom rom/kernel has made no improvement. Anyone got any ideas? I loved this phone before this started, and my phone is so frustrating now that I completely disrespect the thing and have scratched the crap out of the screen. I'm really hoping this can be fixed so I can go on with enjoying whatever life I have left with the g2, if not I'll probably just abuse it until it breaks then switch over to a water proof z2 or something along those lines... Phone was very well taken care of before the problem started, wasnt dropped or exposed to water (other then using outside in the rain for a few min at a time)

I have this problem too, any fixes?
Well I am in shock as to how we all have the same exact problem.
I first thought it was hardware failure on the screen itself and was pretty bummed. But now I see people have the exact same unresponsive touch screen in the exact same spot as mine? What ROM/Kernel are are you guys running? I am running what is in my sig and had not noticed it before until a couple of days ago. Coupled with the unresponsiveness, my Knock on does not work and the phone becomes mildly warm faster than usual. I think it might be a kernel software issue.
Ugh... I was hoping this wouldn't turn in to this big of a problem. I've got the same thing here, VS980 after flashing a Cloudy ROM.
I took over a thread here recently http://forum.xda-developers.com/showthread.php?p=52858791 , but I'll post here again anyways. I wonder if it's the same spot with you guys too. It's right where the install button is on the Play Store, right? For a few hours after it started it went back to normal, then messed up again permanently.
TOT'ing back to 12B didn't help, so I got a replacement device from Verizon. I've yet to send back my old one because I'm worried about the unrooted flag in the bootloader and settings.
I don't have enough posts yet to be able to do this, but can someone alert a dev about this? Particularly in the thread of whatever ROM it was that you last used? A lot of people in the last thread said it came from Cloudy, and I figured it might make sense as Knock Code was supposed to be a feature on there even though the VS980 source wasn't out. Then again I probably have no idea what I'm talking about, but I'd love to hear from someone who does.
I dont think my blacked out area is quite as thick as yours but yes its in the exact same place. To confuse things even more my phone just started working properly again (for how long is another story). Its very odd that It hasnt worked once in 2 months or so and now twice in 2 days its started working.
As a side note I'm pretty sure I started having this problem immediately or very shortly after the OTA kitkat update. I'm now running cloudypro II 2.0 with 3.4.0 kernel, which as i said before didnt fix the problem in the 1 month ive been using this rom.
I originally thought it may have been a software issue, but for it to randomly start/stop working all of a sudden after so long of no function (with no software being added or changed) I'm thinking its more likely a hardware problem? When I fly home on Monday I'm going to try opening up the phone and cleaning the contacts to the from the touchscreen to the mainboard.
If it is software related it may have something to do with air plane mode. I get almost no signal where I'm working at the moment and the constant searching for signal kills my battery pretty fast so I've started using air plane mode the past few days. Thats the only thing out of the ordinary that i've done software wise.
Having the same issue!!

Yes, we've sent it to LG for repairs and they were able to fix it easily.
Sfkn, was your phone rooted when you sent it to them? I'm having the same issue, and it either started happening today, or I just noticed it today, but it's bugging the crap out of me. I'm running stock kk, rooted with twrp and on the cloudyfa kernel.

Had the same today but at the middle of the screen, I pressed on the corners and around the screen pretty hard and it is back to normal(for now).
Hope it wont come back.
You can unroot the device by flashing original rom with LG flash tool.

Erratic ghost touches. Help!!

I recently got a refurbished Nexus 4 from Google beginning of April. I been having minor issues ever since getting it but i never bother to call them or get them to send me a new one since my warranty was expiring around end of April. So since last week, my phone started having these crazy erratic ghost touches lasting either a few seconds where i'd turn off my screen and it goes back to normal or it would last a good 10-15 minute non stop. I rooted it recently and i tried to do a google support. They suggested factory reset, did that. Re-image the device to original state, also did that. The problem continues and its getting a bit annoying. I noticed the problem starts a lot more frequently when the phone is hot or when the battery is below 50%. Is there anything i can do to make this go away or less frequent? Thanks
Also google suggest i call LG to get them to repair it and have my wallet raided. I prefer not to. Since i feel like they cheated me by giving me a crappy refurbished phone that has hardware issue just like the one i bought from them.
ghost touches unfortunately are not uncommon. I experienced them as well, then the lower bottom margin of the touch screen went completely dead. If you take a look at this thread, http://forum.xda-developers.com/nexus-4/help/q-t2810588 you'll notice there's more people on the same boat. There's not much that can be done, it's a hardware fault and probably the screen will need to be replaced.

Phone Has A Mind Of It's Own!

I woke up one morning last week and my phone was acting like it had a mind of its own. It was activating the navigation buttons over and over again even though it was sitting on the table untouched. This made the phone pretty much useless since every time I opened an app the phone immediately closed it.
To try to fix this I completely wiped the phone and went back to stock. After that I update the touch firmware. This did nothing to fix the problem.
Fast forward about five days later. The phone stopped the behavior as quickly as it has started. Everything was fine with it for about 3 days. I could use every function just like the day I bought it.
BUT now this morning it was back to doing the same exact behavior where it acts like someone is touching the nav buttons constantly. They even light up like someone is pressing them.
Can anyone help me out with this? I am going to end up having to sell it for parts if I can't figure out what is going on.

Looks like your screen is on its way out. Replace it under warranty if u can. My first phone did that after some snow fell in the earpiece area last winter.
After that the top part of the screen was no longer responsive. Before that occured, the phone acted possessed like you're describing

That's what I was afraid of. I am out of warranty which means I am out of luck I think. I was really hoping it was a software issue since it stopped for a few days.
What else do you expect? It called "smartphone" for a reason, right? and your phone happens to be the first one with that kind of intelligence. More like the transformer robot blending into your device heheheheh
Anyway, something wrong with your screen, loose end somewhere?

Thats the thing. Some of these screens go bad by defect. I hear its not hard to swap in a replacement. Look into the full assembly with frame so its quicker and easier.
I may buy one as a spare and store it safe in case my screen goes bad after the warranty expires

Same is happening on my old phone, to be specific the digitizer is going out.
Would you believe I woke up this morning and it stopped again?!?! I decided I am going to just sell it for parts. I can't deal with having a phone that is unreliable. Sad day BC I really do like this phone.
