Hi, Everyone! This is my first post on here but I have spent the better part of the last week reading all the different threads. Yesterday my Samsung Epic 4G decided to go a little insane on me. It was working eprfectly fine (especially for a 2 year old phone) when all of a sudden my power button seemed to start cyling and the power off screen kept popping up and the volume keys did the same. I turned the phone off and even tried taking the battery out and giving it a rest but the problem persisted.
Another issue was that some of the numbers no longer worked correctly. The even numbers both on the touch screen and keypad would dial
"2468" instead of the corresponding number; very weird! The phone had never been rooted or modded at all. Well I was able to get into the phone after figuring out a way to input my passcode with the faulty numbers and I performed a hard reset. The phone is back to completely stock but the power button and camera button do nothing. The volume up button works well but the volume down (besides lowring the volume) button causes google search to pop up and then a bunch of letters and numbers to be typed in both the google search bar and in the message of box of the last person I texted. I can still use the phone by opening the key pad to wake the screen up and I can text and call fine as long as I don't touch the Volume Down button. Also, battery life is ridicolously low. I am up for upgrade but don;t really feel like upgrading to the S3 just yet. Sorry for the long post. I know it is against forum policy but I wanted to get the whole story out there. So here is what I am looking to do:
I want to root the phone and install one of the roms to maybe eek out a couple more weeks out of it. Again it works ok now, just the sliding out of the keypad and lack of power button sucks. The phone boots up if I take the battery out and put it back in wihtout touching the power button.
I have read up on Odin and that looks somewhat straightforward. Just trying to see what you think is my best course of action. Again, I do not have a power button working or camera button and a faulty Volume Down Button. Maybe I can do the whole slip in the battery while holding "1" to get it into download mode? This will be my first time rooting a phone so any help is great and appreciated. Thanks and again, sorry for the really long post!
I forgot to mention that the phone is currently running on Gingerbread 2.3.6. This may or may not make it more difficult to root.
Did the phone get wet at all? Use it in the rain?

was thinking this as well
It actually got wet about 1.5 years. I threw it in rice for about a week and never had any issues. The phone has never frozen or had issues the past year and a half. Yesterday it was in the kitchen charging (with a samsung charger but not one for this phone specifically) and it started doing the whole power button/power off screen flashing. I was able to get it in download mode earlier today but i don't know about recovery mode since the power button is dead. Maybe I should root it to see if its a hardware issue?
Edit: I forgot to mention that the phone gets really really hot while charging as well in the area above the battery. Hopefully nothing short-circuited.
It could take a while before the corrosin gets bad enough to affect your phone. I dropped a phone in the toilet once, and it was over 2 years before it crapped out. Took it apart and it looked like an old Chevy wheel well inside.

That is a good point. I never thought of that. It was also in the kitchen which was humid and hot as ever yesterday. Do you think any kind of root or rom could help me squeeze a little bit of life out of my old phone.

Doubtful. If you're hardware's screwed, so are you.

So I left the phone alone for a couple days with the battery out. I go to turn it on today and it worked perfectly. Then after about 5 minutes the power button stopped working again, but everything else is ok. No random letters and numbers and the volume buttons work as well. Now, I'm kind of lost as to what to do. I do have a parts phone, same one as this. Maybe I need to replace the power button? It clicks and everything and even worked for a couple minutes but now is non-functional again.
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.
Where to begin....so I've had my S3 for almost 2 years now and it has run smooth since I bought it. However, about a month ago, my phone just shut off and did not want to turn back on. I tried taking out the battery, putting it back in, using a different battery, connecting it to a charger, but still, nothing. When I would try turning it on, the SAMSUNG logo would flash, the splash screen would play, but then it would just shut off before fully booting up. I tried going into recovery, and I would be in recovery for about 10 seconds before it would shut off. I just tried turning it on for the next hour, and eventually, it turned back on, and stayed on. I thought it was a ROM problem (Was running MOAR v.8) so then I flashed PacMan ROM and my phone was fine. I would reboot to recovery and everything ran great. But....the same problem occured again about two weeks ago. I did the same things as the first time, and it eventually turned back on after about an hour and a half. I change ROMs again and now I'm on SlimKat and things were smooth.....but...once again.....it shut off yesterday. I tried the same things as the previous times, but it would not turn on. My phone would reach the endin of the SlimKat splash screen, but shut off. It has been almost 24 hours since this happened and it still doesnt turn on. Now I am getting worried because it has never stayed off for this long.
Something that may have caused this is my headphone jack replacement. I replaced the headphone jack module myself about 3 months ago, but It was a simple replacement, so I don't think this could be the culprit. I am just lost now and don't know what my problem could be. I have no insurance on my phone, and I am waiting until the LG G3 is released for sprint so that I can upgrade, so I really need this phone to work for another month.
Does anyone know what my problem can be? Any ideas?
Edit: My phone was on the SlimKat splash screen for about two minutes before shutting down. Felt like adding this, maybe it'll help.
Could this be a soft brick?
I really doubt it's a brick of any kind. More than likely your power button is going out. It's very common. You might get away with just taking the phone apart and really cleaning around both the button that you push on from the outside and the actual switch on the inside.
Mind you, this is what I've read and some people have fixed it doing this, but I haven't had this problem...knock on wood.

The power button is probably going out. My S3 which I had for about a year and a half just completely stopped turning on and would only make it as far as the initial Samsung screen when you first press the power button before it would turn off. This problem can't be fixed due to the actual pad is a part of the motherboard. Since Sprint couldn't tell that my phone was rooted because they couldn't turn it on either, the only thing I could do was trade it in for another S3.
Also, when you put the battery in the phone, does it automatically turn itself on without pressing the power button? If so, this is definitely your problem

Thank you both. I will try to clean out the power button and search for a tutorial. Yeah, it does automatically turn on. Does this mean it can't be fixed?

There's a myth that the term "reboot" came from the Apple III (yes they had an Apple 3, totally different animal from the II-line). Word was that it would overheat and the chips would actually pop out of their sockets, and that it became common practice to lift the Apple III a few inches above the desk and drop it to reseat them.
Again, take it for what it is, a humorous story, probably not the truth.

Old, old computer term for pulling it up by the boot straps.
As far as thumping the back of a TV... I have a buddy that was doing that with his HDTV a couple months ago. I took the back of the TV off and it turned out to be a loose cable running from the motherboard to the back of the screen...
The moral of the story is old tech solutions can still work!

Well you're lucky. I've tried everything in my trick book with no luck when it happened to me. I tried tapping the side of the phone and picking at the button to see if that would fix it and even went to the extent of taking the phone apart with no luck.
Ive had a similar issue but my phone will have more than %20 battery and just shut off. Sometimes it has as much as %67 left. Then it won't go past the splash screen till i plug it in. When it does turn back on sometimes it has the same amount of battery and sometimes it says that it has 0. Is there any way i can check if this is my battery just being dead or perhaps it needs to recalibrate or something.
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.
Hi all,
I have a general hardware problem with my Samsung Galaxy Tab S4. Maybe someone here has an idea or tip for me.
I still used the factory software without any rooting or unlocking the bootloader. So everything original and up to date.
A few month ago the tablet began to restart in the middle of using it. At the beginning it happened seldom, but then more and more often. Also during the restart new restarts happened more and more often, so that it took several retries, until it started again. Now it is not usable anymore, because it is not running longer than a few seconds before the next restart if it happens to boot completely at all.
I was able to make a factory reset but this didn’t solve the problem.
My first theory is, that this could be a problem with the battery, that it is slowly dying and had more and more problems to hold the voltage. But the problem also exists when the power supply is connected. So I am not sure if this rules out the possibility, that this could be cause by the battery? Does somebody know how this is internally wired, if a broken battery could still have a negative effect when the power supply is connected?
Do you have other ideas/advices, what could be the problem or would could be helpful to do?
Thanks in advance for any help.
Best
The USB power input can't sink enough current to boot it or even run it without the battery acting as a reserve during peak usage spikes.
Replace the battery and go from there.
Thanks, then I will try this.

Hi Vertex, have you tried this already? I have pretty much the same problem and the battery was also my first intuition, but I don't know if buying a new one is worth it. Thanks!
Hi,
unfortunately I didn't had time to do it yet. I want to change the battery myself and for that I will need time and somebody to borrow me a hot air gun, because everything is glued together.
I will report, when I have done it but it will be at least a few weeks.
Alright, so I'll probably try it sooner, I'll update after replacing the battery. Also, if you haven't tried it yet, you might want to try just disconnecting the battery from the motherboard and connecting again after like 20s, I've read that it sometimes resolves this problem, but it didn't work for me. Fortunately removing the back lid of tab s4 is pretty easy, I used hairdryer, so with heatgun it should be even easier.
Thanks for the tips. I am currently on vacation but when I am back I will also try with a hairdryer.
Any additional tips for removing the back lid to somebody doing it the first time beyond what you can see in the youtube videos? How do you glue it back together?
Hi, sorry for the late reply.
I have eventually replaced the battery, and nothing changed unfortunately… I did a factory reset, etc. However I also had an issue that you didn't describe in your original post, which is that USB connection is not working, it only charges the battery, when connected to the PC while booted it's just not visible at all (tried with several cables, two computers, on windows and linux), when in download mode it kind of shows up, but it's not recognized and no drivers or any solution that I've found are working, so I don't know if it's still hardware problem something with the USB related parts or something in the system on lower level. Well, I'll be trying.
About the back lid. Beyond YT videos only thing that comes to my mind is patience. About the glue, you have few options and it depends a bit on how removing the cover goes. 1) glue stays in the more or less same condition as before removing the cover - that's how it went for me - in that case you can just reuse it, just by closing the cover and pressing it down for some time, it's probably not as strong as new but for me it worked just fine, especially if you use a book cover for the tablet there won't be a problem.
But if the glue came off, wrinkled a lot, or just doesn't stick anymore, 2) you can either use a special epoxide glue often with signature like T-7000 or T-800 but if you just look for a glue for smarphones you'll easily find it. Or 3) Buy a special sticker for this exact device which has a specific shape, it's pretty much the same thing as is used by manufacturer.
