I9500 Screen flickering (Imp.)

Hi guys,
I have a galaxy S4 I9500 version and I have observed a problem with it. I was sharing media with my friend's Xperia Z via NFC, while doing that, my phones' screen started flickering highlighting clock at the top portion.
Later I turned off both mobiles' NFC and taken both mobiles close and guess what my phones' screen flickered again.
I checked it with my old Galaxy S I9000 which doesn't even has NFC, again S4s' screen flickered.
Then I went to service center to show this issue, as they were not having any other S4 there to crosscheck problem, they asked me to visit a Samsung mobile shop. There I checked it with three S4s' which were on display and I found that problem was there with each and every S4.
So guys can you check your phones' for this issue and will it cause any problem to phone as the time passes??

similar type of problem

hii,
i am facing similar type of problem. the diffrence is that i get such flickering whenever i am using the mobile data network after evry few minutes and the flicker is like a flash(means it lasts for a fraction of second). i started to have this issue from past few days and this is extremely annoying.
Dont know wat to do!!

Check this
The S-view will be triggered by any magnet

But I think it could turn into an issue because earlier my phones' screen was flickering and waking up automatically highlighting clock just like shown in that video.
I submitted my phone to them and they have replaced display with new one. Now it is not flickering automatically but it does while holding devices side by side as that sensor gets triggered by any magnet. So there is a possibility that the sensor could get permanently affected by a strong magnetic field and triggers the screen to wake up automatically.

They replaced display with new one and now the problem is sorted out.

Yesterday I tried something with my s4..
I disabled samsung link, clock digital(both of em), watch on, and dropbox.
The problem of flickering and clock appearing on top was GONE!! until......
I turned on the data network and found it coming back again...
I figured that it happened to me since i updated it to UBMG1 Indian firmware from BMEA
So i am now rolling back to the latter and sammobile here i come

Even i have also tried a lot of things... but problem was still there.... i think it messes with hardware and there is only one solution and tht is to replace the display with new one... if you find sonething to sortout this issue without replacing any hardware part...pls post it here....

Same problem here.
Does any one got this solved.. as said by one member, even in chennai - tamilnadu, they are not clear on what the issue i am explaining to them, they just changed the motherboard. but no use still.
"S-view mode activates itself, dono why... it happened for me in a month old S4, i got my motherboard replaced, but still the issue is persisting. but the frequency became less. thats it. other than that no use.
as mentioned by one of the member, it is annoying as it happens any time u work with your phone. in any screen suddenly "

I got my screen replaced but in vain.. I think using the S view cover will help because the flickering is caused by s view initiation (black screen with clock) which is initiated by a magnetic sensor..
Buy unfortunately the s- view cover is costly and so I cannot buy it at the moment .
A possible solution is to turn the s-view service off to stop the flickering issue..
If any developer on the site could help us out..

Many people who had the complaint got their display changed but to no avail so it is definitely a software problem..

- Actually am using the S-View Cover. But with no use, when its out of S-View cover it behaves erratic by switching to S-View display automatically.
-Yes you are right it can be a software problem ,but take my words, i used a S4 which i bought on launch date in India, i used it for 3 months, then i gave it to my cousin, and bought another new one - this is the one which is showing up this S-View Issue,
the old one which i had was a GEM, not even once i had this problem of S-View with it, both where of same SW revision level, hence there is something to do with the hardware.
am just waiting for the October 4.3 update, if this is not solved in that SW by any means, then am gonna **** on every Samsung technician in the service center, they don't even know the difference between Hall sensor and proximity sensor!!!! , for making them understand the problem in our phone itself is painstaking..
in between is there any change to bring this issue to Samsung's eye.!?

True the service center's technicians
Don't know anything...
If you report that the s-view cover also gives the same result instead showing the s- view when it is supposed then I won't buy it because I only wanted to buy it currently just to fix the issue..
Also just waiting for the android 4.3 update..

That's not a issue. It's s-view feature in phone. If your phone get close to any magnet/magnetic source then it will activate s-view screen.
A lot of devices like iPad and Nexus 7 have a small magnet in them to provide support for cover/accessories. If your S4 get close enough to that magnet on other device it will activate s-view screen.
I dont know exactly if your other phone that you are trying NFC with, has a magnet. but there should be.

I know that it is a feature but it comes just in between typing process or running through the temple (temple run) and it disturbs a lot so I thought of using the s- view cover so it will restrict the feature to only when needed out initiated by closing the cover instead of coming every time in between activity..

Not always, see i am just holding my phone in hand, or it is laid on a wooden desk, even then this flickering into S-View mode happens.

S4 resetting / loosing battery

Got some weird problems with my S4.
So I had a rom installed, noticed the phone kept crashing, as in now and again screen would not turn on and it reset, now it got worse and to the point the phone would no longer boot.
So I flashed a stock rom: I9505XXUEMK8
And whilst the phone works, sometimes I get a no sim alert then then the phone resets and I can't get back into the OS without plugging it in.
I check in recovery and noticed even thought the battery life was showing at like 70% it's suddenly down to 0%
So nearly all of the time if I try to restart my phone I need to plug into charger to do it.
I've even flashed with PIT file too.
Any ideas what could be wrong?
Also getting no SIM, signal cutting out then resetting.

A large quantity of samsung S4 was shipped with bad batteries that starts to swell after 2 or 3 months of usage, change the batterie under warranty since this is a know issue at samsung.
kind regards

I had a similar problem with mine. Phoned Samsung here in the UK and they wouldn't acknowledge there was a battery problem and wanted me to send the phone, battery and charger back to them which they reckoned would be a 10 day turnaround. I couldn't be without a phone for that long so I bought an Anker battery as no one I spoke to about a genuine one would guarantee a new battery with a good serial number Since fitting the Anker one I've had no more problems I still want a new one from Samsung though

I'll buy a new battery, I thought the battery was swelling and not sitting in but thought it was just me !!
It is indeed swelling, will it explode?
But does that explain the no sim and signal disappearing?

Check your battery serial #. If it starts with BDxxx or DDxxxx, Sansumg recognized they are dammaged and should replace it to you.

If its swollen then it's damaged.

Here you have your resolution. You have a Samsung recognized damaged battery. Try to change it in the SAT (it should be free), or buy a new one.
Be careful, swilling can damage the hardware by forcing it... in your position I wouldn't use the phone anymore till you have a new battery.

Had the same Problems 2 or 3 Weeks ago. I returned to the store i bought it, a worker there took my battery and checked with the finger how hard it is. After that gave me a new one and problems solved. it is a known problem, no problem to get a new bat.
Edit: Sorry for Quoting you Acer, your advises are good had exact that letters and made in china on the bat, now i have one made in taiwan. The other was getting bigger and bigger, had also fear he explod and so was good he kept it their.

no worries glad that I was able to help

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.

You may need to flash a kernel that matches your display. G2 is made with 2 different panels and if your kernel is using one and not the other you will have an issue like this. Did this start happening after using autorec by any chance?

Try resetting to factory defaults. If the issue persists, return it for warranty service.

Well your situation sucks then ;p do you see the LG boot logo or even that not? can you try to maybe flash KDZ after you have backed up all your data but i guess you need to do that blindly or you need to have LG OSP(on screen phone) idk or you are able to blindly enable it but maybe you should see like an LG G2 review whereyou can see the settings app so you can enable the things you need to get On screen phone working.

guys i still have this problem, any one there who can help me? you guys thin think this is software related ? i sure hope so :| can i try a custom rom ? i never installed a rom before :/

@Demitha I am not sure since it can be both hardware and software problems which can cause a blackscreen.

screen connection problem
hi buddy,
I have the same problem and i think it's a connection issue.
In my case the screen sometimes goes off or changes color intensity or inverse color.
the solution is to knock on the lower side of the screen and it turn on correctly.
firstable it happends rarely but with the time it's comming very annoying.
now just holding the phone hardly or connecting the headphones or charger the screen goes ****ing itself and i have to knock severly or push it to resuscitate it.
i'm thinking in opening the device and look the connections to solve it.

I had similar issue with my previous phone. But I had something like few points where I had to press to get backlight working again, eventually it stopped functioning at all.
As I found out, screen cable was damaged and I figured out that it had been due to dropping the phone or other kind of mechanical damage.
In case if you don't have a warranty or something, my suggestion is to open back-cover and check if you can find anything that is wrong with screen cables. But in worst case scenario it is due to faulty motherboard.

This happened to me few weeks ago, definntely hardware related.
I tried to open my phone and check stuff around, but I'm no expert, and couldn't find anything weird.
So I ended buying a new G2....

My Edge S7 Screenn Dead? Please Help!

Hello All,
I have a huge problem with my screen. This one is blinking, Color are weird and I have a line on the top of the screen not moving. So I really that's a screen problem. and Even when I'm in TWRP , I see on the bottom that there is the screen blinking with a lot of color. It's like when you filming your screen with a camera.
Ok I fall few times but it had always a Spigen TPU and the screen has not strachs , nothing.
The problem is that I've already rooter and instal TWRP but it's cleary a problem with the screen but my Know Warranty is at 1 now
Can you help? Maybe if I go back to a stock Firmware, how can make it look more like the standard stock firmware and try to make it repair?
with a little chance?
Can you help pleasE?
Thanks!

This is obviously a hardware problem depending on in which country you are you might want to try to send it in for repair I don't think that the warranty expired because you rooted it can you send us a video showing the problem? Also why do you think the problem occurred? Did you drop the device?

I rooted yes and the flag is at 1.
I've now restore from ODIN official Samsung Release and bootloader so everything is normal.
I drop it but it was protected and the screen is not broken and there is not even a little stractch .
Do you think they will refuse to repair the screen cause of that? It's clearly a problem of screen.
Not so much but like that. On the bottom. Color are weird. And on the top there is a bar whithout Pixels.

Why have you posted your video as Galaxy S3 video problems on your video on the Galaxy S7 Edge forum? And yes, I'm pretty sure that is a S3 phone you are showing us and not an S7 Edge like you think it is.

It's not a S3 I have a S7 I'm just showing that I have almost the same symtoms on my S7

Can't be much help but it sounds a lot like what has happened to mine, but my display has completely gone now, I've had my phone sent of but they just came back saying it was water damaged and not covered under warranty! Let me know how you get on though! Good luck

It probably depends on the region, but that is clearly a hardware failure due to the drop, which has nothing to do with software. So they should repair it.

SO when people said that you lost warranty when you change the bootloader, if it's clearly a problem of Hardware and not software, they can't refuse it in warranty?

At least inside EU, when a failure is a hardware failure and not related to software, they must repair it.

Ok I'll put it in repair tommorow. We'll see

Maybe it has something to do with the modification you do on the phone. Any app you install. Try a brand new clean on stock and see if it still happens

Already found other guy on YouTube do the same.
And i think a lot of s7 edge do the same
