[Q] Galaxy S4 i337 Touchscreen Issues - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
Not sure if I can ask this as I am a brand new user. I hope you can help.
Friend brought me their Galaxy S4 i337 4.4.2 stock firmware. It acts as if the very top left (or around the area) is permanently pressed not allowing for any other touch function unless I touch that area "taking over" the ghost touch. The moment I let go, it is brought back to that area of the digitizer. Sometimes it works for half a second or 2 but goes right back to the problem area soon after. I have soft reset, hard reset with no avail. I have also connected a new LCD assembly which works perfect. I am assuming after this that the digitizer is the problem though I am interested what would cause such an issue to only part of the digitizer. She did mention she is prone for dropping the phone though it had been about 24 hours after the latest drop that the digitizer started acting up and has not let up since.
Any ideas ?
Thank you and again I apologize if I am not allowed to post this here.

At&t 8525 touchscreen problems, please help

Hello,
I've recently been looking around online to figure out a solution to my problem and I came across this forum, I honestly had no clue of all of the things possible with this phone...
I have an At&t 8525 (in august I will have had it for a year) and just yesterday I started having problems with the touchscreen, when I would try to use the touchscreen nothing would be functional...after messing around on the screen I found out that the lower right hand corner of the screen (the right hand corner when the keyboard is in use) pulls up the start menu...although the touchscreen didn't work the phone itself still did, I could access the start menu and other actions on the phone by pushing the soft keys...
This morning I started toying with my phone again and it worked normally for some time and then eventually the screen started to do the same as it was doing before...so thinking that the problem was a virus or something, I figured I would reinstall wm6 back onto the phone hoping that it'd restore everything to normal...now I'm stuck on the 'welcome to windows mobile green screen' and only once have I gotten to the 'align screen'...
I truly don't know what or how to fix this problem with my touchscreen and I'm really new to all of these phone experiences...(I'm pretty sure returning the phone is out of the question)
So any help given would be very much apriciated,
-Ben

This is a loose connection between the main .. device and the touch screen . There is this cable that connects the screen and the keypad .. that has a loose contact. press the screen and the keypad together and the touch sreen should start working again . i had this same issue i don't know how to fix it.
Sounds like this problem here:

The above is an old thread. You can try the old business card trick (though it's by no means guaranteed to work). You could try a dis-assembly and reconstruction, double checking connections - particularly the screen to d-pad connection.
The Hermes unlike the Kaiser is very prone to this kind of problem and despite the threads you may see, guaranteeing a fix, I don't believe there is one fix for this problem. This is because there are several variables that can cause the problem and it just depends whether your case is caused by:
Dust trapped under the bezel
A loose connector - possibly d/pad to screen
A failed capacitor on d/pad or main board
Another failed component
Digitizer coming unglued from LCD
etc

Had the same problem right before EVERYTHING went white. Replaced the lcd altogether, about $110Aud on ebay, and everthing works great again.

[Q] Replacing LCD and or Digitizer

Hey guys,
I just ended up with a g1 for a good deal. Only problem is that the touchscreen has a problem were it will shake back and forth between screens. I mean If im on the home page, and i slide it left or right to the other pages. It dances between the 2 for a couple for a seconds. Also I cant touch anything in the bottom right hand corner of the screen. So that brings me to my question. Since the glass is intact, that would mean that the digitizer is busted? As you may have noticed I really dont know. But if anyone could offer any help in my direction because I'd like to fix this myself. As Always...
Thanks in advance,
Lord CraiguS
Please i have the same problem. I would like to know thanks.
Same problem
As for me, this problem started when i`ve replaced the digitizer with a new one. It seems exactly the same as you described. I`ve noticed, that it dissapears temporary when i block the device (power button) and unblock it again. But sooner or later it appears again.
I suppose it is some internal bad contact in connection or in a flexcable of touchscreen.
However, not solved this problem yet.
Seems to be that i found a solution at least for my G1. I`ve installed a new CyanogenMOD 6.1.0-RC1 (i had 6.0.0 previously) - and the problem is not appearing for at least 2 hours!
I suppose it is somehow related with software handling of touchscreen taps.

[Q] is the touch controlled by the digitizer only?Could I have damaged anything else?

Hi,
HISTORY:
I've had my defy screen shattered a while back and sent it to Motorola for repair (they did a terrible job at that). Ever since I got it back I can see small dust particles accumulating inside the screen. Gradually after a couple of months the top right corner became non-responsive and I left it that way for another 4 months until now!
As the warranty period was over, I thought of trying to clean the dust and see if that works. Unfortunately the connector on the touchscreen(digitizer) broke off and it stopped the touch completely.
My Question:
Is it possible that I had damaged something else(can something else be damaged?) that caused the touchscreen to cease functioning? :crying:
I can change the digitizer after buying it from ebay. But I would hate to waste any more money if this doesn't solve the issue. How likely is it that the touch functionality will be restored if I change the digitizer?
LCD is working fine, and I can use the volume rocker and power button perfectly.
P.S. please don't flame me for asking already answered question, I've been through a lot of threads before opening this one.

[Q] Touchscreen Randomly Stopped Working

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.

Note FE - Touchscreen issue

Hey y'all,
Picked up a SM-N935L a few weeks ago. Last week, for no reason I can think of, the touchscreen started causing problems.
As of now, a 1 inch swath of the screen on left side doesn't respond to touches unless they are long touches. This is annoying on the homescreen, but IMPOSSIBLE when trying to type on the keyboard as the number key, shift, A, Q, and 1 key barely ever respond to touch.
AT first it was intermittent. Now it's permanent.
The S-Pen works perfectly, even in the affected area of the screen.
I tried flashing the original firmware the phone came with before the OTA, no dice.
Long story short, the phone is now back in it's box and I am back to my old n9005 Note 3.
Has anyone else run into this?
Before someone says that maybe the screen connector is loose on the motherboard, I cracked the phone open (heatgun, etc) and checked that. Not the issue.
I even tried the secret code *#6233*# which allows you to "update" the touchscreen firmware. No difference.
Any thoughts?
you didn't mention the software version you're using.... did you update to the latest OTA for the L version of the Note FE? Google Translation change log
Build Number: N935LKLU3AQG6 Android version: Nougat (Android 7.0)Release date: 2017-08-04
ㆍ Improve the phenomenon that the tone of the song is reduced or silenced in a specific environment
ㆍ Correct the phenomenon that the photo position information is displayed when the camera is shot
ㆍ Intermittently break when touching the upper / lower touch
Build Number: N935KKKU3AQFEAndroid version: Nougat (Android 7.0)Release date: 2017-07-06
ㆍ Apply stabilization code related to camera operation
My bad for.not being specific. Yes I am on QG6. I went back to QFE hoping for a change. No difference.

Try *#2663#, which will update the TS firmware. Used this recently to correct a touch screen reversal (which was a weird experience at first).

Sorry. That's the code I used, not 2633. It didn't help at all.
Have you installed any apps that control screen brightness, remove the brightness slider from quick settings? If yes, uninstall and see if that fixes the issue.
Very late to the party but I'm having the same issue. Tried everything and no luck. The left side of screen not responding unless I use the pen. Stock OS no extra apps installed. Gutted.
I also have this problem..after one month use..right side screen doesnt respon..
Im runing on ARA1 firmware
hi pro, did you fix it, i have same issue
I had the right edge screen problem too. You can use *#0*# to test. Select touch to start the test.
Press 'volume up' button once done.
My problem on the right side and only not responsive to touch only. S pen works fine though.
I went to samsung and they said they had replaced the screen. And it works ! So guys, maybe it's really a hardware problem with the display screen.
Now after 2 month, the problem had resurfaced
I really like this phone and my note 4 previously was great and not having any hard problem.
I'm going to send this again to samsung for repair since it's still under warranty. Hope the problem will diasppear and not repeating again once we warranty expires.
Hello, i am having the same problem. It started about a week ago when the left side of my phone became unresponsive to touch. I have to long press the left side of the screen to register my touch. I tried the "Touch" test at *#0*# and the left side cant be touched. Now the lower and right side of the screen became unresponsive too. Anyone knows how to fix? Using Android 8.0.0 on this Samsung Galaxy note FE
exactly happen to me too...
went to samsung center and replace the screen, under warranty
Same Here
Hi
the same issue started happening to my Note FE yesterday.
have you found a way to fix it? or have you returned the product?
BAD NEWS everyone
Hey y'all,
So I have bad news for you.
The problem is hardware not software. I ended up giving my dad the phone when he went on a business trip to Hong Kong. He's got a guy there that owes me a favor or two so he got the screen replaced. That fixed it immediately.
Sorry for not updating you guys. I ended up just picking up a brand new Note8 back in Nov when I had enough of the touchscreen thing. When my dad finally brought me the FE back with the new screen it worked perfectly.
No software changes at all. Just replaced the screen.
Hi !I am having the same problem here with the right side of the screen.
First it started when the right side started to be less sensitive but then after a while it suddenly stopped working for the touch. The S Pen works ok.
Its really terrible to use it like this. At least if there was an option to squeeze the screen. Where did you guys bought the phone? I am in Europe but i think the company imported it from Saudi Arabia. Dont know if its a regional issue but i am courious. I tried clearing the cache and updating the touch but no difference. Haven`t tried factory reset yet....

hi what is your update about your screen problem ? and for how long did you use your note fe before this problem appeared? maybe you dropped it or something?
Hi. I'm having the same issue. I'm in Saudi so maybe it's a region thing?
Right side not working with touch but only for the s-pen. Also now the s-pen or finger has wrong touches in the screen.

I have been using it for about 3 months before it first started to lose its sensitivity and then to not function at all on a 1 cm wide area on the right side. I havent dropped it for this to be an issue and since i already seen other people complaining its definately a manufacturing issue. I have sent it to the service and hope to have an answer and i will update here about it.

My phone is also imported from Saudi Arabia. It could be a problem with this region, i don`t know.

Hello, do you know if your phone was imported from Saudi Arabia? It might be a problem with the phones for this market.
Thanks all for your reply. Really its very scary, just brought a new one from Saudi Arabia, where made in Vietnam. Sometimes I feel some lag with back button . But I dont think its common defect, I heard about same problem in Note 8. Those screen curves brought troubles to all of us ,
I installed tempered glass screen protector but it didn't cover the whole screen , anyway I preferred it rather than the normal elastic one.
Exactly the same issue on my FE
Nope. It happened to me as well just this morning. It is exactly as you've described. I did a factory reset but the issue still persists.
