Hello all!
I have noticed that recently, my phone has been doing a very odd thing while charging. When it has been plugged in for a little while, and the screen is on and in use, sometimes the phone will crash. When it crashes in this manner, the backlight on the screen is turned on on full brightness, the screen gets a yellowish hue, and horizontal black bars start appearing on the screen. More black bars keep appearing until I reset the phone (hold the power button), and then there is no evidence of any screen problems. I also generally have to unplug it for a while, as if this happens once, it generally happens multiple times until I unplug the phone and wait. These problems seem to be occurring at odd times (a lot at night, before I am going to sleep), and have just started happening (I also recently made the upgrade from the latest version of GB to 4.0.4). I have had this device for about a year now (the second device, the first one had a physical design flaw and was replaced), and I am out of warranty right now, so any help would be appreciated!

That was happening to me (for a weird reason, my devicewas new, its seems that problem is more common in the rogers version dont know why) but, if your problem is the same problem that i had, then, just install stock ICS with oneclick (dont remember the name very well)

Superoneclick? That's the closest I found, and it doesn't say that it supports the Glide. And, I am running a fully stock version of 4.0.4, unrooted and everything. I might need a little more help here, haha.
I mean, oneclick, is the firmware,and is about 700 mb, give me amoment a will search it
EDit: i found it: http://www.androidauthority.com/captivate-glide-sgh-i927-att-android-4-0-4-ics-uclg9-leak-110365/
I use that, when I install it, that problem gone away, try it. And then, you can flash the custom recovery and install custom roms

Isn't that a different version though? The build number on that is UCLG9, not UCKJ3 (which is what I have right now).
I am not sure, but, if with that your problem persist, maybe is hardware, but I only do that. When I did it, that was the latest version, now there is another version but not sure what is it
I was having the same problem, except it was happening frequently after my phone had warmed up due to normal use. If the phone was already hot it wouldn't even get past the splash screen.
I put it down to hardware fault, and was successful in getting it replaced under warranty. The new one has been totally fine.
Hopefully yours isn't a hardware issue - but from how it sounds it very well could be

I really was hoping it was a OS issue, as it hadn't ever done this on GB. If I flash a new rom then, it would be fixed?
Also, I too noticed that my phone is abnormally warm when it does this. I do have a cover on my phone, but I noticed that it seems to be centered about on the horizontal center of the phone, about a half-inch below the camera. If this is related, what do you think it is?
My phone did this as well. Luckily it happened just before I rooted. The att guys said it was a hardware fault and that fault also killed my battery. I'm assuming it was a short. It started as something infrequent, but it eventually escalated to the point the second I turned it on my screen turned completely green and got really hot.

Just great, a possible hardware problem while out of warranty. Did yours do it only when charging as well?

Didn't have to be charging to do it. Could have been on the street holding it. (I was on GB as well)

Your issue sounds similar, but slightly different. Mine only happens while I am charging it, and it has only done it since a while after I made the upgrade to 4.0.4. Although, they sound similar, and my phone also gets concerningly warm, so I have no idea if it is the same thing or not...
If it's out of warranty, then you have nothing to lose by doing a backup and a clean ROM installation, which is what I would do. I guess if you do it when fully charged and while the phone is cold you should be fairly safe, especially if you use a small ROM. I've found the latest M3 10.1 ROM installs fairly quickly, so that might be worth a shot even just to see if it fixes the problem.
The only risk you're taking is that the phone might die and get bricked in the process if it's a hardware fault, so I guess it's really your call.
EDIT: On that thought, perhaps experiment with seeing if you can charge after leaving it in the fridge for about 15 minutes? It's a trick we used to use to recover data from failing hard drives, if you get them cold enough they can work for long enough to get away with things

I like that idea, as it should fix the overheating issue. However, the times that it actually has this malady aren't regular - it seems to happen more at night, but not every night. I could try putting it in the freezer when it does it though, and see if it works. If it is overheating, could it be a hardware issue then? I also noticed that my battery that I have in my phone does appear to have a slight dent near the bottom, and it is only happening when it is charging, so I am wondering if it could be a problem with the battery? When I pull the battery out after it has done this, the battery itself isn't that warm, but the phone is, so I'm thinking it isn't the battery, but does anyone else have any ideas?

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?
Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.
Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?
Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird
Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random
Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.
mine got fixed by removing battery.
I just got this tablet (to replace the garbage SGH-I467) a few days ago (Thu., May 15th). For the first couple of days it worked like a dream. However, the last 4 nights/3 days, I have been encountering some strange issues. What I will do here is describe the issues I've been having, what I have done in attempts to fix them, list some of the things I think may have caused it, and include any additional info/questions.
Before all that though, I would like to mention that I am not a developer, but I am a bit 'tech savvy' and am more familiar with/knowledgeable of technology than the average user. Also, I have spoken with Samsung tech support and even had the support guy access my Tab Pro 12.2 remotely (I will explain what I learned from that below). So, without further ado (I apologize in advance for the long winded nature of this post, but I want detailed):
The Issues:
1) Screen "flickering"—By flickering I mean that it is shutting off and turning on rather rapidly and sporadically, though inconsistently.
I first encountered the problem 3 days ago (the 18th).
Four nights ago (the 17th), before going to bed, I plugged the device into the same outlet I have used for all my mobile devices, when I woke up (on the 18th) the screen was doing exactly what I described. I hit the home button a few times and it stopped.
That night (the 18th) I plugged it back in to the usual spot before going to bed. The next morning (yesterday, the 19th), the screen was "flickering" again. I tried to press the home key a few times, as well as both the soft keys, nothing. In between "flickers" you can see the lock screen, where I have to enter a pin, but even while visible I can't type anything. So this time, to try to solve the problem, I held the power button + volume up to get to recovery and wiped the cache partition, rebooted the device, and viola, it worked again. Thinking that I may have to factory reset the device if the problem persists, I used Kies to backup all my data. I used the tablet the rest of the day, even plugged it in (in a different outlet than the one next to my bed) for a while and had no issues.
Last night (the 19th) I did pretty much the same thing, but this time, thinking that it might be an issue with the device getting too much power (the Quick Start Guide says: "Note: Connecting the travel adapter improperly may cause serious damage to the device."), I used a travel adapter from one of my other, USB 2.0 devices (the only difference between the adapters is the output: 2.0 = 5.0V—2.0A vs. 3.0 = 5.3V—2.0A, and output was specifically what I was concerned with). This morning (the 20th) the problem has returned, but now includes my second issue: the hard home button and both soft keys, back and recent apps, no longer function. So I immediately tried to wipe the cache partition and reboot, but this time it didn't work. Thankfully I had anticipated this yesterday and had that Kies backup, so I wiped the entire device back to factory settings. But alas, it was unsuccessful and the problem persists, including the loss of button functionality, with the exception of the power and volume buttons.
It is important to note that when I first got the Tab Pro 12.2 and set up the lock screen, I used the option that delays the actual locking of the device 10 minutes after screen timeout, but set it so that if I lock the screen with the power button it ISN'T delayed and immediately locks. That being said, a couple of times when the "flickering" stopped long enough to momentarily use the device, I was able to enter my pin and unlock. But when the screen starts flickering again, it locks the device, so the power button must be affected as well. Though since the first factory reset of the device, I haven't set up a pin. I have done several factory resets and none of them have worked. The best result has simply been limited (no back, recent apps or home key) and momentary functionality. I tried using Kies to do emergency firmware recovery, but every time I click the option it disconnects the device.
When Samsung tech support remotely accessed by device (I used one of the momentary functionality windows to download the required application) the agent was able to utilized soft and home key functionality, even though I couldn't. This tells me that it was hardware related, not related to UI/software.
So there are a couple of things I think may have caused/contributed to the problem:
The first, which I vaguely touched on above, is the power issue. Perhaps I have shorted the device out somehow. The outlet I use to charge things while I'm sleeping is on the wall behind my bed, so I have to use a common extension cord, one that has 3 outlets at the end. I have a light plugged into that and in the past have charged both my SGH-I467 (AT&T Note 8.0) and my SGH-I747 (AT&T S4 Active) with that cord and outlet. That is the only place I have charged the SM-T900 overnight, but none of the other power sources I have used have caused these issues.
The second possibility is a virus some sort. I have never used the Samsung app store on any of my other devices, but in order to update the Hancom Office suite I had to. Since I had an enjoyable time using it to that end, I decided to see what else I could find on Samsung's store. I downloaded a couple of things (the "Official Captain America game" and a couple wallpaper/theme apps) and was looking around the store to see if there was anything else I wanted to download. I found several apps that had reviews claiming they were trojans, so I immediately checked the reviews for the apps I had downloaded, but none of them had similar reviews. However, that does not mean they didn't have viruses.
So, what do the resident Android gurus of XDA think about these issues?
I tried searching all over the forums and elsewhere online for people having the same issues, but couldn't find anything. Have any of you ever encountered something similar to this?
Until recently, I hadn't ever heard of anyone getting a virus on an Android device. Are they common? What is the nature of Android viruses?
If these issues do have something to do with overcharging/shorting the device, how can I mitigate that problem? Tonight when I charge the tablet, instead of using the USB 3.0 charging cable, I am going to try just using the 2.0 cable. As I understand it, that can be done by simply plugging it into the right side of the port. Hopefully that will stop exacerbating the problem.
Again, I apologize for such a long winded post. I would like to thank you all in advance. If ever I have problems with an Android, you guys are the ones to ask!
*UPDATE* Before I started typing this I was attempting to run the Kies 'Firmware Upgrade and Initialization', as opposed to 'Emergency Firmware Recovery', to see if that too would disconnect the device. Unfortunately it said that my device needed to be charged first. So I shut it down and plugged it into a surge protected strip and began typing this post. Occasionally I would go over an check the charge. While it was shut down and charging I was able to use the home key to bring up the green battery. Once the charge looked like it was about 75% complete I turned it back on and lo and behold, the "flickering" issue looks resolved and so does the button issue. I can go back, enter the recent apps and task manager, and use the home key functions. For how long this will last, however, is unknown. I guess we'll see in the morning. I'll post what happens tomorrow.
What kind of case are you using? Some users have seen issues with some cases that use magnets for auto-sleep-wake. When the front of the cover is flipped back behind the tablet, the magnets seem to activate the auto-sleep feature

same issues here
Sounds exactly as the same issue I have had the last week. I have done several factory resets triad to avoid installing as many applications as I had prior the factory reset (to see If it was an app causing the issue). No solution yet but I will try your way with kies described above. I have a tab pro 8.4.

I am no guru, but it sounds like a loose connection. Maybe it is affected by temperature. Try it on a (not too) hot water bottle or on freezer packs.

It's not overheating. It can get warm, but it's never gotten hot. And I've had other devices that have seriously overheated and still functioned, albeit slowly.
**UPDATE**
After I got it working the night I originally posted I let it fully charge (it's important to note that I got it up to about 75% while it was off; green battery the only thing on the screen, and I had home button functionality), then disconnected it and disabled all the radios, put it in power saving and left it over night without power. Doing that I was able to use it all day yesterday. But while I was full-charging it, after it reached 100%, I noticed that it started acting up almost immediately. The sound was on and kept making the lock screen sound (that's how I noticed it from across the room). So it is tied to the power/lock key. But disconnecting it before it could get out of control mitigated the problem. Last night I was going to try to charge it over night with USB 2.0, but I fell asleep before changing the cable out, so it charged on 3.0 all night and is back in poor repair. I'm currently trying to full charge it while off to see if that gives me functionality again.
Either way, each time I fix it the solution becomes more difficult/timely than the previous one. It's clearly not getting better, so I'm going to have to send it in to repairs.

Sorta sounds like a screen grounding problem. I had a nexus seven with this issue and the charger seemed to really make it act up. Needless to say I gave that to my wife and bought this. If the digitizer is not grounded properly it will act up.
Turning on developer settings and set it to show touches on screen. See if when charging the screen registers more touches than you are doing.

Damn! That's an outstanding idea! The only downside is that last night I sent the tablet to Samsung's repair department, so I can't test that out. But once I get it back, if the problem persists I will definitely be doing that first. Thanks for the advice dottat.

Hey dude, check out dottat's reply. He's got a really good idea that may shed some light on the source of the problem. Unfortunately, I can't try it out. If you do it, let me know how it goes. Maybe you can take some screenshots? Either way, hopefully you can get something out of it.
I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
This problem just started about a week ago. Sometimes after a few seconds of the screen being on, it will flicker, mostly at the corners. However, most of the time it will distort and eventually fade to black. It mostly seems to do it when the phone is warmer. For instance, in my office at work or home, where it's cool, it will not happen hardly at all. But in my truck on the way home, outside, or if I can feel heat on the back of the phone, it does it a lot.
All of that said, I know of the paper/eraser trick on the camera connector (which is very temporary, from what I've researched), but to me this seems to be a GPU/heat problem. Basically, I'm just trying to understand why this might be occurring. I don't want to order a new mobo and have it do the same thing. So, any help would be much appreciated!
How often is this happening to people??

It happens to me about 15-20 times a day. More on the weekends because I use it more.

I had a similar problem for about two months. I tried the paper thing over the camera sensor and I felt like it helped some but the problem still continued. The screen would just slowly go dark with vertical lines running through it. All apps would still work in the background while this was happening. I could boot to TWRP and this problem never happened while in TWRP which was odd. Seemed like if it was a screen issues or hardware malfunction it would happen all the time. That's when I decided to just flash back to stock. I was thinking about getting the S8 anyways so what the hell. I flashed to stock 10B and took every single OTA. Took all night but I've been running stock for over a day now and the issue has not replicated itself one time since reverting back to stock. I was on RR Nougat and Fulmics when it happened prior. Has to be a root or Rom issue? What ROM are you on?

I became so fed up with the issue that I caved and bought the Nexus 6P last year. My G3 was on stock OS, no ROMs. Pretty sure it was a hardware issue. I turn it on every now and again, and the same thing happens. Never really solved it. I may try flashing some ROMs at some point, but I think I'm done with Samsung devices for the time being. I absolutely love my Nexus 6P. Great phone. Waiting for the new version of the Pixel or the rumored new Nexus haha.
It's an issue due to bad quality soldering and the SoC overheating. When the phone is very warm (and the G3 tends to get quite warm on the Camera) and you keep using it, the bad soldering starts losing con ection.
So you're basically losing connection to your chip and that's why the phone is experiencing those problems. That's why putting pressure on the chip helps to restore the connection.
It's best to use a thermal pad and it's the best solution there is. Some people bake their motherboards but I don't recommend it since this always kills the motherboard in a few months.
You can also try looking for a replacement motherboard online.

Mine screen fades to brightnes, and strips when phone is cold. when it gets worm hot screen is almost perfect. same thing with two mobo's.
Hello , nice to meet you all. I am a new XDA user so apologies if i do any mistakes.
Yesterday, i got the 2 GB Ram variant of the LG G3 D855 from a relative. The phone almost works fine, except for two problems:
The first problem is that sometimes, the phone either locks up for about 3 seconds and shuts off (or maybe the screen shuts off? not sure), or either it completely reboots on it's own. I know, there is already information about this on the internet, however, some people say that it's a battery problem, some say it's an overheating problem. I am just confused. By the way, the issue happens no matter if the phone is charging or not. It also happens even when the phone isn't overheating, although it happens less. I may try a battery replacement, but unsure if it will fix it or not.
The second issue is, it's not really a critical issue, but it's just annoying. For some reason, especially when the phone overheats, the screen's right bottom side starts glitching (It also mostly happens on the home screen for some reason). And no, i don't mean flickering. Some glitchy lines appear at that portion of the display for about a millisecond and then goes away most of the time. Today the phone overheated when i was watching YT once and those lines appeared for like 5-10 seconds.
Also, i've noticed that the phone overheats a lot. Like, it gets quite hot sometimes.
I've already tried a factory reset, but it did not fix anything. The phone is running the stock Android Lollipop 5.0 firmware by the way. I did not want to take a risk trying to upgrade the phone to Marshmallow or install a custom ROM because of these problems.
I don't want to spend too much on the repairs of this phone since i've already got an another phone with almost the same specs as the LG G3. But i also want to use this phone. I just like it's design so much. Please tell me if it is worth getting it fixed and what i should do to get it fixed at the lowest cost possible. By the way, i don't understand much about the hardware of smartphones (I will get it repaired to an expert). So please, try to explain the problem as simple as you can do. Thank you and i wish you all a great day.
UPDATE: I've also noticed that the phone also has the screen flickering/disappearing issue.
However, asides from that, i've found an another issue too. So this evening, the phone was overheating too much so i decided to let it cool down a bit. So i closed the apps and put it into sleep mode. After about 5-10 seconds, the phone started doing REALLY LOUD tv static like noises. I immediately pulled the battery out, and i am afraid to turn on the phone because of that. I think the sound didn't come from the battery but i am still afraid.
I will bring the phone to a repair centre. But at this point, i don't know if it is worth getting it repaired. I am so confused. Is the phone dead or not? I've tried pulling the battery out and trying to boot the phne while it was getting charged (DON'T DO IT for your safety) and i get the "No battery" screen. I hope anyone that understands the hardware of this phone will help me. Thank you all.
