Strip of unresponsive screen when powered on for a while? - Galaxy Note 4 Q&A, Help & Troubleshooting

So something I noticed on my old note 4 is that the screen has a strip unresponsive to touch (pen works fine).
The thing that weirds me out is that when you reboot the phone, it works perfectly fine, but after being on for a few hours, the middle part of the screen just stops responding.
Rebooting revives the part of the screen, but not for long. Factory resetting it does nothing different and it's running completely stock firmware and software.
Any ideas as to what's causing this? I'm not sure if replacing the screen would help since it seems to work fine for the short duration that it does.

It sounds like a digitizer problem. I wonder also if the heat of the phone is causing something to change or even physically warp to cause the unresponsive part.

Either a blown display or mobo.
A trace, solder joint, micro weld or junction failed.
It's possible it could be a connector/ribbon cable failure in which case easily repairable.
Check the display/mobo ribbon connectors...

I'm pretty sure it's not heat since you can turn it on, leave it on a table, idle without anything running, and it'll be completely room temp and the part of the screen stops responding.

Could be literally 100s of thousands of parts that could have failed; semiconductor junctions, resistors or caps.
Solder failures aren't uncommon either.
If you spare parts, use the process of elimination. If you really like that model having a few parts queens around is a plan.
Hopefully it's a connector contact... check all connections including grounds.
For $650 you can get a Note 10+ 512gb in excellent condition... don't got too nuts trying to fix it.

i'm not using this phone, it's my dad's old phone that i just want to mess around with since he put it in a drawer a while ago. I don't really plan on putting much into it. just hopefully get it running well and to **** around with roms on it.
Also $650 still isn't cheap for a phone when you're paying cash outright :v
at least a lot more expensive than a $50 screen replacement or $35 motherboard

I gave you a top shelf example.

There's no guarantee swamping out parts will fix anything. The devil is in the details.

Sorry to hear that.
Some devices seem to defy being repaired.
45 years ago Tom Schall owned a TV repair shop. He was an excellent technician with a engineering degree in electronics.
He swapped out a trouble filled Magnavox chassis with a known good one for a customer after repairing the original one at least twice only to have another circuit fail.
After a month he did the swamp but continued to try and fix the original. He repaired completely different sections of it only to have another one fail, HV, tuner, horizontal output, audio, and more.
Never once did it survive a couple days of burn in, sometimes only hours. It got to be a running joke. Hundreds of test point checks, scoped it, testing isolated components pondering how it could be so cryptic to repair. At this point no one else would even touch it... but Tom persisted for at least 3 more years in his spare time.
If there's a heaven or hell I'm sure Tom's still tinkering with that chassis. RIP
They weren't called Magotboxes for nothing

See if this works for you, it did for me after i thinking digitser was kerputt.
on Dialler, dial: *#2663#
if a menu comes up, choose the top left option to upgrade the fw for touchscreen, wait for complete, then hit home button and see if it works. Maybe best to try after your screen goes funny, it should fix straight away

That worked at first, but I rebooted the phone and it seems to be doing it again. I tried to update the firmware again, and it's not working. Any advice? It worked fine for over a day without any issue after doing that at first, now it's back to doing it again.

Sorry late reply, I didnt get a notification. It worked for me and I haven't had to do it again, it likely sounds like you have a hardware issue unfortunately.

Only other option maybe, is putting on a custom rom, which will instigate a full system wipe and a new fresh software install to a more modern Android version. Possibly may be worth a shot?

Alright, update.
i tried again, and it fixed it, but a while later, it did it again. Since that seemed to fix it for a bit, i can't imagine it being solely a hardware problem.

honestly, that's the plan as of right now. As much as I like the S-pen features on this, it'd be for the better if it fixes it.

Update, TWRP + new rom installed. Still does it.
With Refined Nougat N7FE, I'm able to open the screen firmware menu from the dialer and update like with the stock rom. It sometimes fixes it for a while, but ends up doing it again.

[Q] just purchased a g2 for $30. screen doesnt turn on

The phone definitely boots up because the lights on the buttons flash on then turn off after some time. The keyboard also lights up. You can tell the backlight turns on on the screen, but there is no picture.
Anyone have any idea about what I should do? Thinking about trying to restore to a stock Tom somehow tonight. Then I'm thinking about looking for screen replacements.
I was curious if anyone has had this issue before.
Update 07/14/11
So I got the screen and switched the old one out for the new one. This one also only has the backlight turning on, but I noticed when I put a part back on, there was a little bump in the middle of the phone. Haven't had a chance to fix it, but I noticed it's a piece hitting this rubber piece that seems to "transport" the sound for the mic from the bottom of the phone to the actual microphone module within the phone.
Removed that rubber piece, and I'll try installing it later. I was getting some blue and red visible in the middle of the phone. Anyone know what's wrong?

How sure are you it's the LCD screen? Replacement screens cost more than what I bought the phone for...lol
it's mostly the physical connection to the screen.
and on your note about it costing more than what you bought the phone for... there are tons of parts on the phone that will cost more than 30bucks. not much you can do about that since you got it non fully functional.

Never had to do it myself, but there is a cable connecting the two parts of the phone. That is usually where this problem originates from. It's not easy to fix though if your not familiar with fixing electronics from what i have seen.

I've taken apart my laptop completely and put it back together before. Completely as in taking the lcd off and different chips and wireless modules and stuff. I think it may be something I can handle. I'm going to take a look at it now. Restoring wont do me any good because not even the boot screen shows up.

So I completely tore apart the phone, got to the point where if I had another LCD screen, I could have easily switched it out. But I don't, so I just put it all back together. I really hope this new LCD will fix the issue. I really hope it's not some other motherboard issue. If all else fails, it goes up on eBay for $70-$100 as is for the phone. If I fix it, I just got myself a phone that goes for $200 used for only $57.
sure. goodluck with it. if you can do it then you're all set. good luck

Sorry. After some searching on eBay, I found some sellers selling it for a few dollars less than 30, e.g. 27.
But I decided to go with a seller who sold more than 200, who claims the screen is an OEM screen, and who is top rated. He sells his for $32. Which makes my phone $62 after all is said and done.
The housing has some scratches on the top and bottom though, which decreases the value a bit, but hey, if it works I'll probably keep it as a backup. Currently have the HD2, but I got a Vibrant with original box and accessories for $100, so I think I'm going to sell the HD2.
That was kinda off topic, sorry
LCD screen should be here by the 13th.
Updated OP
someone help =|
I don't own a G2 but I still think this could be a similar issue to what we get over here on the HTC Droid Incredible. First, what makes you believe its still a screen issue if it lit but just didn't throw picture? Usually thats the symptom of having the wrong recovery version for the device hardware version. Normally for us what happens is we will get somebody who is new and rooting for the first time and they'll end up flashing the wrong recovery or freak out because they don't realize the root process takes a little while and yank the cord. End result being exactly what you've explained above. Phone starts but no screen. So we end up having them do the ruu or a second option which we call a "blind install" where you drop whatever your p file(ours is PB31IMG.zip) so whatever it is for the G2 drop that on the SD and reboot to hboot and do the update process by simply knowing how long to wait between key presses and what keys to hit without useing the screen. Its a unique process and all very magical. Haven't lost a single Inc yet because of this issue.
Anyways bud just a thought...

It doesn't seem to be a ROM issue.
Update 7/18: Sold the G2 on eBay and still made a good lump of money. I was very happy, until another G2 popped up with the same exact issue. Got it for a steal as well, and I tried the OEM screen I got from eBay, and it was still having issues, and it seems to cause the phone to overheat while charging. Definitely a defective screen and someones getting a great deal on a decent condition G2 because I already took the payment after I figured it was the screen I got.
I'm going to try to get a replacement from the guy that sold it to me on eBay, but I already left him positive feedback thinking it was the phone's fault.
Will update probably late July or early August when all of this gets sorted out.
TL;DR: bought 2nd g2 with same issue, turns out replacement screen didn't work in the 2nd g2, too late to not sell the first g2, getting another replacement screen to fix 2nd g2. First g2 was in better condition though =|
SWEEEEEEEEEEEEEEEEEEEEEEEEEEEET
Just installed the second screen that I ordered, and it works PERFECTLY. Phone is perfect nowwww yay. I can't use it right now though, previous owned put a lock pattern on the phone...
Wipe the system and the data and start over.

Took it apart, put it back together. Somehow it works better just from doing that?

So, took apart my xplay today because my screen was having issues and I wanted to see if a cable was loose.
Couldn't tell what was wrong, so I put it back together.
After putting it back together, I noticed a few things.
1. The power button that had always been loose was suddenly tight and in one spot. I thought the phone was just made that way. Turns out mine was improperly assembled right from the time I opened it. Gotta say, that button is far less annoying now. Anyone else have a loose power button?
2. My battery. Before taking it apart, my battery was at 19%. After putting it back together, suddenly my battery said 43%!! Suddenly it's got more? The heck is going on here?
3. My screen hasn't glitched again so far. Even though I didn't actually do anything other than unplugging/screwing and replugging/screwing some parts.
4. Originally, the left trigger felt "mushy" now it clicks like the right one.
On a side note, after seeing how the slider works on the inside, I recommend ONLY opening the slider when you're actually about to play a game, and not just fiddling around with the phone. The way it's designed makes it very obvious to me that the ribbon connecting the screen to everything else is easily destroyed. It wouldn't surprise me if my screen was having problems because of that ribbon.
Edit: NOPE. It's totally screwed.
Edit again: When the screen is glitching, moving the slider makes it start working some of the time. I'm becoming more and more convinced the ribbon cable inside the slider is the problem.

Really strange screen issue

Hi all
So I just installed a few games on my Nexus 4 this evening and noticed some areas of the screen not responding. Its isolated to about a 1cm from the left on my screen. When I enable the "show touches" option under developer options I can see the ball jump when I move my finger over the area. Whats odd is that the very edge reports OK and I can swipe to Google Now without issue.
I was using PA with Franco and just as a test revered to stock and it seemed to work however after about 5 mins it went back to the same behaviour. Once again I installed my stock nandroid and now its just jumping like it was. So confused!
I guess some software is running and causing issue or the screen is over sensitive in that area me touching it is causing issue. Its worth noting that I changed the screen a few days ago so it could be the connectors but could it be isolated due to a connection?

Ok so I was able to use the old screen (cracked) in a frankenstein fashion and it works 100% of the time. The current seen seems to work for a while and then goes back to missing that area.
Will try and return for a replacement.

Update 3
So the issue has progressed to being intermittent. It will be broken for a few hours, then work OK for a few. This can happen at random,so, not plugged in as I suspect heat was an issue. I can get a text, its broken, pocket the phone and in 5 mins when I get the reply it can be working again.
Ive made a video of what its doing, notice the white dot "jump" when compared to the right.

You need a different screen if you want to fix it.

Check that the flex cable isn't damaged, dirty or loose before you bother with a replacement. Either way, you probably need a replacement screen

Yea I took it all apart and while the new one was connected I was able to connect the old one, upside down etc. It worked OK. Did a bit of a blow and properly pressing down on the connectors.
I could accept the screen is at fault at return it but when the issue is not 100% of the time I know my luck will be that when it gets tested at the sellers end it will work, get sent back to me and be broken again.
Have some monitoring apps running now so I can tell of its heat. Since this side is away from the battery im less incluined to think its heat from that. The motherboard does run down that side so it could be something in that? Ever seen any reports of that getting too hot?
Could even be heat from the antenna cable somehow?
Strange that it spans the whole length though.
Ill risk the return I think, got a video of it being broken so will see what happens.
Run over to Radio Shack (or whatever the equivalent is in what ever country you're in - I don't know where you are) and find a product called Deoxit/Progold. Deoxit cleans the contacts from oxidation, Progold enhances conductivity. Or find something similar.
This stuff is great for blasting inside headphone jacks to get rid of the "scratching" when your plug gets moved around, to fix iffy USB connections, etc. A little goes a long way. I don't know if it'll solve your screen issues, but it's worth a try, and if it doesn't work, you can still use it on other things, so it's not a waste of money.

Wow, that stuff isnt cheap. Lets hope a little does go a long way!
Thanks, have ordered a small bottle, will give it a go.
I noticed that my new screen is genuine LG (at least its stamped all over it) but the one I removed seems to be a 3rd party replacement. Its got some areas that "look cheap" in comparison. Its got a small foil coating over the flex cable where as the one I removed didnt. I assume its to protect and move heat away?
Few forum posts mention the use of 3rd party chargers....I have used a cheap one when I am in work. I have used in on my old HTC Desire HD and my Lumia 520 and never had an issue. Do you think it could have damaged the digitiser?

Interestingly enough , the original digitizer is wrapped with aluminum tape. Some knockoffs have a better cover in fact. They use a hard aluminum sheet instead of aluminum tape. Some knockoffs don't have that shielding which is bad because that tape is there to keep the IC from getting spammed with useless data by radio frequencies and such.
If you haven't dropped your device , i don'T think it is likely that there is a problem with the glass. It's most likely the IC.
You could transfer your old flex to your new glass which is easy but you need some seriously steady hands.
When you remove the glass from the frame , you will see the flex cable's contact zone. It's basically the part where it connects to the glass. If you heat that area up with a heat gun it's gonna come right off when the solder beneath melts. Take out the new one and the old one. You need a flathead tip for your solering iron , which is like a flathead screwdriver. Simply take some solder and spread that solder around the contact dots , don't worry it won't stick to the plastic but it will melt if you keep it at the same spot too much. When you're done spreading , there are two dots with which you can align your old flex cable to your new glass. Use some adhesive tape around the alignment dots and Align the dots with your flex cable (you'll know which dots when you see it because it's orange and kinda stands out) press it so the adhesive holds and then use your heat gun and melt the solder to the contact zone.
It's actually easier than it sounds.

Water damage story.......insight wanted.

I bought a friend of mine a LG G2 and within a couple weeks she managed to have it take a drink. The horror on my face was, well, horrifying when i was told. Anyways about the phone.........
She knew to immediately put the phone in rice which she did.a few days later i get the phone into my hands, moment of truth right? First thing i did was to take it apart and see if there's any corrosion on the board or any leftover residue which i found none. reassembled the device and plugged it in for........well i dont know why, i just did. I read online if the phone shuts off immediately after contact with water your chances are good. Anyways the phone showed signs of life. It began booting up past the LG logo to the boot animation of "Desolation ROM" where it freezes and than loops freezing at different times of the boot logo.
Download mode works so i decided to flash the KDZ 20C. The phone boots up entirely into the OS and works with few *issues. Two things i have problems with, the internal storage doesnt appear** on the computer regularly, and i must "adb reboot recovery" a few times before it successfully will boot into recovery. but i can manage with that. I rooted it through sideload, installed autoRec and got TWRP flashed and working. I did flash the new TWRP so that it mounts the storage to computer. anyways so i went to flash the rom, Desolation, Resurrection Remix, and Bliss pop with the same issues. ive dont everything multiple times already to no avail.
Ideas? anyone?
*issues: it thinks the headphone are plugged it and rapidly cycles the animation.
** it varies from one flash of the KDZ to the other i can "adb Push file /sdcard/"
Solution: buy her an old Nokia
Buy a new logic board.
Sounds like this one is toast

From my experience over the years water damage is a 50/50 shot.
On one hand you get a 100% recovered device with minor repair...i.e replace battery and or LCD and you're good to go.
On another hand you have weird malfunctions i.e headphone jack saying its plugged in when its not....dead wifi, dead vibrate, no data connection...the list can go on and on...
When this happens, unless you're skilled to replace the ICs on the logic board with some skillful soldering, I'd pass and either sell or use the phone for parts.
Start fresh with another used G2....maybe one with a broken screen you can get cheap and swap parts over to your phone.
Oh yeah...have your friend buy herself an S6 Active...

Have seen a few logic boards in ebay sell cheap the last 2 weeks. You may get lucky and replace the board with a newer/better condition one and fix your problem entirely.
I'd recommend buying a new battery too

How does the screen look?
I'd inspect the LCD and light box underneath to be safe as well.
If both look like new you're safe there.
Basically:
New logic board
New battery
New screen (if necessary )and youre good to go

Lg g2 makes me cry

So I've had my phone (d803 canada telus) for 2 years and it's been fine for most of it but a few months ago it started to reboot over and over, sometimes when im using an app or sometimes just sitting there.. sometimes it reboots right away and others it takes a whole night of wait to start again. Is there a way to fix this, i have performed a factoty reset and it didng didn't fix the problem.
Weirdly for about phases of a week once in a while the problem would stop amd and id be like whoa cool but it would start again and this time it looks like its gonna stay. Please help? Called and the only thing they said i could do was "repair" it for $149 but nuh uh. I don't even know what could have changed to the phone physically because i take good care of it.
not sure if goign back to stock again a tot or kdz installation might help.?
or maybe you have hardware problem

What kind of hardware malfunction could cause a phone to turn on and off 40 times a day?

It could be anything. A single bad capacitor could ruin a phone. It's rare but it does happen from time to time. Like raptorddd suggested, try to tot back to stock following THIS GUIDE. Then update to th latest ota and factory reset. If that doesn't fix it then it looks like you need a new phone. Good luck.
Had this issue when my battery started dying.
Got a replacement and the problem went away
If you take the phone apart you may notice the battery could have started to swell

Ok so I took my phone apart and didn't notice anything that weird except that it was reeeaallyy dirty inside, dust all over the place, mainly at the bottom where the speakers are. I cleaned it mostly but I don't think that's the problem. But I looked a little closer at the battery and it doesn't seem swelled like you suggested but it had tiny dents. Would I need to get it replaced? Don't even know how this could have happened. Would pictures help or is the desc enough
Yes. It's not holding proper voltage
