Having some random and annoying screen fluctuations. Its like the screen depolarizes and the images become distorted and somewhat inverted. Happens off and on and reboots do not help. Im gonna go back to stock just incase it needs to be sent in and to see if the ROM I am using is completely to blame, I have tried reflashing too.
Just thought I put this out there to see if anyone else is having similar issues.
I may have had something similar the other day - basically the color blue would go away, and the remaining R&G pixels would smear. Best way to describe it would be to pretend that there is a specific frame buffer for blue, and it has a pointer, and that pointer was getting whacked. Meanwhile the pointers for the red and green buffers were having less-significant bits screwed with. Yeah, like I said, "pretend". My initial gut said it was a simple case of some bad silicon on a line driver. Done.
While getting ready to exchange the Tab (aka removing stuff), I discovered the behavior was strongly impacted by memory pressure. If you've played with ESXi, you know what I'm referring to. If not, go read about Ballooning.
With lots of crap floating around, screen gets more wonky more often to the point of being unusable. Including during the boot splash screen. Remove the junk (not programs - just... stuff, music, browser cache, whatever)... less wonky, less often. Still wonky, mind you, but less wonky, and less often.
Decided the culprit was likely Task Manager by Rhythm Software. Removed exactly it, cold started, and never had an issue since. Note that I'm not really keen on saying Rhythm's work was at fault, especially since saying "it's fixed!" is trying to prove a negative and this is not a reported problem. OTOH, the behavior did start within a few days of installing it, and the behavior's ending exactly coincides with RTM's removal.
In that sense, take a close look at what you're installing - something otherwise fine might be suffering an... unexpected feature.

Thanks for the tip, mines still looking like hardware failure. Sometimes when i put it into the samsung keyboard dock it randomly clears up, as if the jiggle in the pin connector port affects it but it will reappear eventually.
Been trying to use the return to stock stuff from the main sticky in the development section but it keeps erroring and failing in CWM when I attempt to flash. Oh well.
Thanks for the reply yo!
I think its because the stock rom they have is p700 and I am p7510 or whatever. Am I in the wrong place? lol Time to scavenge the forums.
Unroot for Return
So, I made my backup copy of my ROM after it was rooted. How do I get this thing rooted again so I can take her in? I tried using the info on the stickie in the Dev section but I get an error when flashing the supplied stock ROM, repeated, no mistakes I am pretty sure.
Any tips?
also, hasnt been 30days, should I just go back to best buy or call samsung?
I have the exact same issue with my tablet and going to return it for warranty. I had to unroot and get it back to default blind, since the screen is almost never readable here (too much distortions).
I got it back to factory default (unrooted) through ODIN + Download Mode. Use the files and step-by-step guide on this webpage: http://droidangel.blogspot.com/2011/06/samsung-galaxy-tab-101v-p7100-stock-rom.html
I got the same problem. the screen just distorted, which happens on several custom ROM. It happens after heavy use. I have to put it aside for a couple of hours to get it back to normal.
Is that hardware issue? If it is, how could you convince the shop to get it replaced?
you may not be able to reproduce it at the shop.
I lost my interest to samsung product. It took quite some time to create an account and file a case. Now the webpage just keeps telling that it is processing the data.
I remember that I have never succeed to create an account through the TAB.
very bad service.
Well, mine's finally going in for repair.
As mentioned in the post above... after removing a few apps and most of the data from the tab... not a single issue with the screen, since.
Then... the behavior came back last week, gradually becoming worse until the colors are just plain hosed. Blew out the browser caches, wiped any remaining data... pulse, etc... and it cleared back up again... for about an hour, but rapidly reverted back to horrid. Did a hard reset... no avail.
It is quite the interesting behavior, to say the very least.
It's not mechanical. It's not thermal.
Is samsung service center the only solution for this?
Does yours look like this?

(Sorry, you;ll need to fill in the obvious missing doys. It was either that or posting 8 random posts)
My Tab also has similar issue and it still appears after hard reset, trying to convince the shop to exchange or help me to send back to Samsung.
Did Samsung cost you any charge for repairing? The shop say it need charges and they don't want give any help.
not really. Mine has distorted display but more likes adding white noise.
Seems that sumsung really sucks. products have so many different issues.

I was covered by seller warranty. I sent it back, and the seller sent me a new device. I don't know where you're at, but usually sellers are required to handle this for you, if under warranty, _by law_. This is obviously a manufacturing fault, not bad usage.
Hello,
I'm hoping someone can shed some light into my delema...
I've been researching regarding my issue but haven't found any answers as of yet (I feel like I'm the only one with this annoying problem).
My problem happens more times then I would like. I would be browsing the web, watching a movie, or just on the desktop screen, then all of a sudden the screen starts wigging out on me. It would shift erratically left or right, zoom in and out in a spastic way and while all that is happening it doesn't respond to touch. The only way I would recover from it is if I hit the power button to close the screen then on again. That seems to remedy it temporarily until it decides to act up again at random times. My other issue besides that, is that touch would become unresponsive at times when just going through the motions. Turning the screen off and on again would fix it but will happen again a few more times during the day.
Has anyone ever have these problems and if so have you been able to remedy it? I may end up having to return it to Costco online and get it replaced.
Things I've tried: (Not in order)
- Removed root and set it back to stock.
- Hard reset.
- Flashed different rom
- Removed all third party apps
- Full wipe
(Thanks for reading)

If you've done a full wipe and format before flashing ROM, it very well could be a hardware problem, as the wipe and format should have removed all residuals of previous ROMs, so you can rule out OS/software as the issue.
Just an educated guess.

Sorry I didn't post what I did in order. Yes I've done full wipes before flashing any rom. Even as far as to bringing it back to stock and it would seem fine for a bit then out of no where it would just wig out on me.
You could be correct of it being a hardware issue... Sucks that I may end up having to return it.
Edit: Actually I haven't tried formatting. I will give that a go. Thanks!
Edit 2: Didn't work. Off to Costco I go for a refund:/ I may just decide on a different tablet.... Ipad2 maybe? LOL (Just kidding)
Hi JJdeVega: Have the same problem a day after i bought it and the problem was the touch sensor malfuntion. Returned and exchange to Costco with new one no more probs.
I am not sure why ,but lots of tablets that come from Costco seem to me have issues.or is it that they just sell more then anyone else.
I have similar issue but with font size shrinking to smaller then readable at times.ideally while browsing web forums.I have to close browser and start again.I believe it has to do with site adds changing.

Hey, that was my exact problem and just for u to know all the things u tried were software related and the problem really is hardware (or at least in my case) the touch screen has a malfunction in it but to make sure u can just download 'touch test' free from the market and leave it open for a while or when the problem shows and see for ur self its like invisible fingers are touching ur screen and that was to make sure that the problem is hardware related if so do as i did .. replace it
hope that i helped
If I helped u in a way or another click "Thanks"
very good
Well said good info on the program wish I knew before. Thanks for the info.:
Is it only when charging the device? If so, this happens to me too. I don't know if it's the tablet being faulty, or charger, or the power that's generated for my home, but it is VERY annoying. I can not use the tablet while charging. I can't return it now, as it's been maybe 3 months already? Anyway, just wanted to let you know that it could be only happening when charging.

if u have a warranty it doesn't matter how long u have been using it, i got mine replaced after three months use so u dont have to return it u can just ask ur agent for a replace because yours has got a problem in it ( if u do have an agent and warranty)
Press "thanks" if i helped u
Thanks everyone for all the suggestions and replies. I ended up returning it. Then found the Samsung Galaxy tab10.1 right next to the Acer, so purchased that instead. Kept it for another two weeks with no issues then came across the New Asus Transformer Prime tf201 and couldn't be any happier! Too bad Costco doesn't have it since it's all online pre order. I would totally take advantage of the 90 day return policy!
I am experiencing the same problem, but it is of a fairly random nature. it comes and goes. When I contacted J&R about it, they forwarded me to Acer customer service who ask me to send the device on my dime both ways, they would test it and decide if it qualifies for a replacement or if they send it back as is. Uhh, I am not happy. Anyone having similar experience?
Really weird.. Out of nowhere , the bottom right corner of my screen has become almost totally unresponsive to touch. The L and the backspace button on my keyboard are nearly unusable.. Anyone have any idea as to how I may be able to fix this? Its like there is a 2 inch by 1cm gap on my touch screen that doesn't respond to touch.. Thanks guys

Nexus 4 touch screen defect (dead zone, phantom touch)
I have the same problem, I have a permanent ~1cm tall dead zone spanning the width of my Nexus 4, right about the location of the SIM card tray.
On occasion it is not a dead zone, but rather a "very haunted zone" where there are MANY phantom clicks/drags on different areas of the dead zone in VERY QUICK SUCCESSION. When this happens I have found that constantly resetting the phone (maybe 5-6 times) until it returns to normal (see: dead zone) is the only way to fix it.
That whole situation can take up to an hour to sort out, especially since during the orgy of phantom clicks/drags on the dead zone, the touchscreen is essentially a write off and turning it off is next to impossible, meaning that my phone is bricked for a portion of the day. This happens arbitrarily about once every 5 days.
I purchased my phone from Australia one month ago. Was not aware of any problem until I had returned to where I am currently living in China. I'm absolutely gutted that my first android experience has soured, especially after shirking apple because of (living through years of) their own hardware/software issues.
Why can't I just have a quality, working piece of tech?
So far the warranty options available:
1) Store I bought it from says: Send it to LG Australia (1 non-international warranty)
2) Google says: No google store purchase number, no return
3) LG China? - Can't find any information about LG warranty claims in China.
If I send it back to Australia for repair I will be waiting without phone for weeks, AND I'll get taxed at least $100 by greedy China customs when the phone comes back in. (not to mention the postage there and back)
The problem has become worse and worse as have used the phone. Can any of ye android bros possibly offer any sort of advice or even better, a fix, for solving this problem?

I have this right now. It's about a third of an inch located near the middle of the screen. It spans the entire width of the screen.
I sure hope it's just a software and not a hardware issue. I bought this in the US and I am now halfway around the world.
I had the same problem. For me it was right where the middle row of keys on the keyboard are or where the ring is on the lock screen.
5mm thick bar across the screen. I sent it back to be fixed and it's been fine ever since touch wood.
They replaced the entire screen on mine. This is definitely a hardware issue. I did a factory reset before I sent it back and the problem was still there.
Digitiser is too close to surface I think causing problems.

Guys i have the same problem since this morning.
I tried everything change roms 4.3 / 4,4 and finally returned to stock.
Nothing worked although i had never the same problem before.
So i tried my last chance. Changed radio image with the help of a Toolkit of our forum ( thanks N-Cry Toolkit )
It seems to be fixed for now , i just rebooted.
Hope it will be ok and you could fix yours too

well for me its a hardware issue, but since you said it worked fine when you changed the baseband it really surprised me up
actually happy, cuz there are many users who has this problem.

Had the same touch screen issue for months; had a dead spot in the middle of the screen that would interfere with browsing and games.
Updated OTA to stock KitKat just last week and the problem went away. Hope you guys get lucky as well. :cyclops:

Ok... i created an account here because ive had this same problem for the past month at least, but I think i found a fix. It may take a few people to try it as well to see if its definitive.
I have the same 1cm high deadzone spanning the width of my device just lower than halfway from the top.
My troubleshooting led me to this: If its hardware, its only because the software is telling it something it shouldnt be. I'm sure nothing is broken (i.e., from being dropped, etc.) Something is wrong, for sure, but not broken per se.
I took screen shots of temperature and voltage (using CPU-Z app) trying to figure it out. I paid attention to when it happened and when it did not. I boiled it down to two possibilities: temperature and/or voltage (i can explain how i came to this conclusion if you want... would take a bit more explanation).
I charge my phone with the charger plugged into the wall typically. I live in asia so the voltage is a lot higher (but within the appropriate range of the phone). Yet, lately when i go to sleep, I plug my phone into my laptop to charge, rather than the wall... when i wake up the problem isnt there. About 2 hours later or so the problem comes back.
I tried this for a week (charging my phone with my laptop) and the problem is dissipating. As quickly as it escalated (getting gradually worse) it is now getting gradually better.
Try it and see if it works for you. At night when your phone is nearly dead, charge your phone with your USB port attached to your laptop. Try this for a few days. Maybe it will help. Im still troubleshooting specifics to see if it is definitive.
UPDATE: today, the day of writing this, i haven't had the problem at all and it's been nearly 7 hours and the 3rd consecutive night of charging with USB on my laptop.
Nexus 4 - 4.4.2
My dead zone appeared post-Lollipop update
I created an account for the purpose of also reporting this "dead zone" issue.
I elected, on the Tuesday before Thanksgiving, to opt into the OTA Lollipop update. During the process of updating, I noticed my battery drained all the way to 0, while I thought nothing of it.
When the update was complete, I started to notice a dead zone in the middle of my screen when in portrait mode.
Actually, my dead zone spans an inch of my screen.
I have performed several hard resets, soft resets, learned about the ADK & adb, and downgraded all the way to 4.2.
I took the phone, this morning, to a cell repair shop and the technician said that it's not a hardware issue (although I'm not sure he's right).
So, that's my story. If I find a solution, I'll post it.
these dead spots IMO , are because of bad battery or bad charging ...
have any of you facing these issues have used any wall charger other than the default nexus 4 LG charger ?? maybe ur battery was not charged the way its suppose to be .. or maybe ur battery is getting bad.. can sm1 with the problem replace the battery and see if the problem get solved ???and u can try charging it from the original lg charger for 12hrs straight .. it may(temporary) fix the problem /...

i could try the battery replacement on my nexus, when i get the time, ill get back to you if it works....
ok got the dreaded dead spot where the sim card is, i can't unlock my phone. i dont have usb debug enabled, i can push/pull files in recovery but not much more.
ive tried to change the dpi to move the pattern away from the dead zone by editing build.prop manually and pushing it to the phone but cm13 doesn't seem to take the change to build.prop so the dpi is stuck at 320.
now, im trying to set up usb otg and unlock my phone using a wired mouse and y-cable. but quanta doesn't have otg for marshmallow enabled out of the box and i dont have root access to enable it in an app.
is there a file that i can edit and push to the phone to enable otg_hack?

i did it, battery has nothing to do with the screen, its better to just replace it.
UPDATE:
It seems the problem I have is ghost typing. Based on FourPointedFreak suggestion, I activated the Show Touches option in the Developer Options menu, and now I see ghost presses on the touchscreen, always in the same place, about 1.5 inches from the bottom and 0.5 inches from the left. If I try pressing with my finger in the same spot when the mark shows up, it slides down before I can even get to the screen. If googled it, and it's been reported on some Android phones and ipads, but not on the S4, and there is no agreement if it is hardware or software.
If you've dealt with something like this before, even with a different device, your input would be most welcome. I'm planning to change ROM tomorrow or early next week, and see if the problem continues. And clean my screen with a soapy moist towel, so far I've only used a cloth for glasses to clean it.
I'm really hoping it's a software issue as I don't want to do a warranty replacement, I'd be most probably get a device on MF3. But if it is hardware I'd rather have that than a faulty device. I got it refurbished as a replacement for an Xperia Ion, and I only have one more month left of warranty.
Again, any input especially from past experiences would be greatly appreciated.
-----------------------------------------------------------------------------------------------
LAST UPDATE:
It seems the problem is hardware, as the false inputs in the screen happen also in TWRP while trying to flash the new ROM. I guess any mod can close this thread now.
josemald said:
Hi everybody, in the last week I've had issues with the display. First it started like going up and down in scroll menus, like if I was scrolling up and down around a certain position very fast. In the last two days, after that happens, the touchscreen gets unresponsive (it didn't use to happen before), including the menu and back buttons, only the hardware buttons work. Home screen button works fine, but I can't do anything in the screen. The only solution is to turn the screen off, enter PIN, and then it starts working. A couple of times the screen keyboard started acting weird when I was typing, for example if I wanted to move the cursor in an email the keyboard interpreted as if I was pressing a key, which was way below. Again turning the screen off and on solved it.
I'm using Mint Jelly ROM, which has been stable for almost two months. I recently updated the modem to MF3, but only the modem and not the firmware. The screen issues were happening before that, it just got worse today. I also tried freezing Samsung WatchOn, which started acting out by showing itself on the notification panel even though I had selected the option for it to not appear, and I uninstalled the Software Update app (used for OTA updates) using Titanium Pro, since I saw it in the list of running processes. The problem still continues.
Is it possible that this is a hardware issue? I have 1 more month of the warranty (I got it as a warranty replacement for a Sony Xperia, so it wasn't new). If I don't need to send it back I would prefer not to, since the one I'd get would probably come locked with MF3 firmware. If you have any ideas on how to debug this, I would appreciate the input. I haven't installed any new app recently.

Well, you're definitely smart for doing your research before just pulling the warranty card.
I would do some testing and research with the phone to figure out what the cause is. It doesn't sound like something that can be just 'debugged'.
Go into your developer options on the phone and enable a few things.
To get developer options, go to System Settings > More > About Device and tap on "Build Number" until it says you've enabled it.
Then go into Developer Options (Above About Device) and under input, select both options "Show Touches" and "Show Pointer Location". Then under Monitoring, enable "Enable Traces" for anything applicable to what you're having problems with.
Some of these settings may be annoying, but continue to use the phone as you would. See if it's adding and doing things you're not, this would show clear signs of a malfunction with the firmware. Check for dead pixels too. Sometimes a dead pixel can cause things like you're dealing with. Where something is selected on the screen much lower than where you pressed and variations of that.
Also, have you tried reflashing your ROM to see if that makes a difference?

Thanks for the suggestions!
Do you think it´s possible that the problem was caused by a dirty screen? I know it sounds a bit insane, but yesterday I wiped off my screen to clear dust and smudges, and since that I haven´t had any issues with the phone. This is the third touch screen device I had, I've never seen something like this, but also the S4 screen is a lot more sensitive than my previous devices. Could it be that too much dust and grease made the phone interpret that there was some input?

I would think it's 'possible' but it would have to be thick and really caked on there to make a difference. That may have just been a coincidence of timing with your issue. But perhaps it is.
Maybe go buy a cheap screen protector to help with finger prints and dirt and see if it gets better?
If it persists, I would factory wipe and install the stock ROM through Odin. Use it a bit completely stock and see if the screen works. If the issue continues then its an hardware problem and i would take a video and e-mail Samsung about it with the video. I've actually had this problem before and that's because my phone was cold as hell. Doing a lot of benchmarks so i put it in the freezer (I would NOT recommend that) and my screen started acting up and it pressed random things like yours.

Doing a lot of benchmarks so i put it in the freezer (I would NOT recommend that) and my screen started acting up and it pressed random things like yours.

That's a good idea. Just make sure you flash the custom ROM appropriately as not to brick your device.

It seems the problem I have is ghost typing. Based on FourPointedFreak suggestion, I activated the Show Touches option in the Developer Options menu, and now I see ghost presses on the touchscreen, always in the same place, about 1.5 inches from the bottom and 0.5 inches from the left. If I try pressing with my finger in the same spot when the mark shows up, it slides down before I can even get to the screen. If googled it, and it's been reported on some Android phones and ipads, but not on the S4, and there is no agreement if it is hardware or software.
If you've dealt with something like this before, even with a different device, your input would be most welcome. I'm planning to change ROM tomorrow or early next week, and see if the problem continues. And clean my screen with a soapy moist towel, so far I've only used a cloth for glasses to clean it.
I'm really hoping it's a software issue as I don't want to do a warranty replacement, I'd be most probably get a device on MF3. But if it is hardware I'd rather have that than a faulty device. I got it refurbished as a replacement for an Xperia Ion, and I only have one more month left of warranty.
Again, any input especially from past experiences would be greatly appreciated.

Yeah, I have heard the term "ghost typing" before. I couldn't seem to find much information or help on the subject as I'm sure you noticed as well. To me, and many others on the internet - this doesn't seem software related to me. This would seemingly be an issue with the hardware. Maybe the screen itself, the data connectors for the screen's signals - could be all kinds of things.
If I were in your shoes and you really like the S4, i'd just take advantage of the month you have left on your warranty and get a new device. If, and they probably will, they supply you with a new(er) device with MF3 on it, it's not the end of the world. Mine got stuck with it - there are methods to root it even still.
To me, cleaning it just doesn't sound like it's a solution. I've worked for T-Mobile, AT&T and Verizon. Only twice had I seen an issue like this where you can attempt to press "E" and another key was hit in place of "E". We never found a fix - this occurred on demo phones so we related the issue to it having demo software.
The only other 'solution' or fix would be to replace to screen to see if it fixes. But since you have a warranty, for the trouble - i'd just get a new device.

Thanks, that's what I'm going to do. It must be hardware related, since the problem also came while I was in TWRP after formatting the phone. I like the S4 but a locked down Android, not so much. If rooting is enough to be able to tether, I might ask for another S4, if not, might as well try to migrate to Windows Phone. It's ridiculous that we have to pay extra just to be able to use our limited data plans to navigate through a different device.
Again, thanks for your help!

No problem - yeah there is definitely a way to root the MF3 build of the S4.
Since you mentioned it, my only note ***If apps are important to you, Windows Phone is a dangerous field. Many apps available for Android and iOS are not available on Windows Phone. I'd make sure the content you want is available before switching.
I can see why the carriers would charge additionally for tethering. If you can make an extra buck, do it. But it does suck. Especially when you have unlimited data and want to tether.
-Do some research on Windows Phone in case you're seriously considering switching. I wouldn't though
Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.
I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.
Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!
I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?
Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.
I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

My phone is also random Rebooting
It also shuts down at 25% of battery remaining, Have you also faced similar issue?
Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.
This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4
You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.
