[Q] strange freezes - Galaxy S 4 Q&A, Help & Troubleshooting

every now and then when i pull my Verizon S4 out of my front pocket (screen off), it seems locked up when i try to wake it. sometimes the bottom buttons are lit up (menu, back) but the phone is unresponsive. i hit the power button a few times, or hold it for a while, press home, or whatever, and it generally reboots eventually. any idea what could be going on?
could this be a samsung sensor that it is in my pocket? i don't think it has ever happened outside of my pocket, but is has happened 3-4 times now.
it never feels warm, so i don't think it is overheating. i have a TPU case, so i don't think the power button is getting hit (although maybe it is).
i'm on Beans 6 with the KT kernel, but i think (i'm not positive) that it happened even when on stock.

Iv had very similar problems, and have been doing some reading, and it looks like it could be battery related... some one on another forum (could be this one cant remember) said that they had the same issue with there stock battery... I have just replaced my battery yesterday, ill post back later 2day\2moro.
For me when it was in this locked up mode and i connected the charger, the state of the phone was like it was fully off, the green battery charging icon would be shown on the screen, and then i could use the power button to turn the phone back on.

interesting. let me know what you find.
since this is happening when m phone is asleep (unlike many complaints about it happening when using specific apps) I am curious if it may be related to my KT kernel tweaks, which i copied from an expert, and which set certain CPU parameters to save battery when the phone is asleep. i'm going to try reverting those to default, or maybe try a different kernel.

Hey Mate, so far the phone has been real solid, iv had no lockup or anything with this new battery... still could be coincidence.. but its working great!

XV6800 wierdness. Dying?

I've had my 6800 for several months now, running a DCD ROM from about 2 months ago. Love the phone, love the ROM. This morning however I lit the phone up and everything seemed OK until I needed to make a phone call. I tapped the "call" button and nothing happened. Tried the "messages" button and same thing. Every button is inop except for the power button (well, the networks button worked once but then it stopped working as well.) I did check the "buttons" setup and everything was mapped correctly. I've rebooted multiple times. I noticed that the unit was getting unusually hot. I use it all the time and have never felt it this hot. Then out of the blue it throws a low battery warning (at 1pm? Never, ever happened before.) I've got it charging now, but something is certainly wrong with the phone. Anyone run into this before?

Your phone might over heat if you leave the phone charging for too long or if you are using it extensively while your charging it.
Also if you leave your phone charging for more then it is supposed to, It will lower the performance of your battery. So once your battery is done charging you should unplug it from the power cord.
I am not sure about why your buttons are not working. It would be that it got stuck in in standby mode because of lack of memory. I usually soft reset once a day or once every two days to keep my phone running smoothly.
I see where you're coming from, but the overheating is happening with it in standby with no charger connected. It really starts to cook when I bring it out of standby and use it. I've also done multiple soft resets at this point.

Is your phone running alot of processes in the background? how much free RAM do you have at startup?
Also, the worst case scenario is that you have a faulty battery or phone.
My phone has never over heated but it has heated up when I leave it on the charger for too long.

Failing Galaxy

My galaxy seems to be having a few problems recently. It is randomly switching itself off, I must admit battery isn't the greatest but its still charging and seems to work OK.
A few days ago it took about half a hour to switch on. The screen was fine, but every time I pressed the power button, I had an empty battery indicator show.
I'm not sure what's going on. Anybody else seen anything similar? Put the battery in, get a battery indicator? Press power button, get another battery indicator? Apart from this, its working fine now, but still sometimes switches itself off.
Why dont u flash another rom...
Still under warranty? - take it back in.
If not, I would flash a different rom..

My Desire Z wont turn on... [HELP]

Hey
Usually I dont use caps in titles or "help" "urgent" etc but something has happpened to my Desire Z and now it just wont turn on.
Basically I left it charging with the green led on and when I went somewhere I noticed that the green led wasnt on but I supposed that it was actually blinking notifing me of some notification so I didnt even look. When I got to my destination, I went to turn it on and usual way a press of the power button. The screen didnt light up. I supposed it was some kernel panic or something so I simply took out the battery and put it back in and pressed the power button to turn on. This is when I started to worry: It didnt turn on. I again took it out and in and still nothing. Only at ONE point did it show the white HTC logo booting then it went black again and still nothing.
I came back home and plugged it into the charger, another fear: No LED at all. Im trying it with and without the battery and it seems like nothing. Seems dead.
Is there any other test I can do or something? Im worried about it....
Also, it is rooted so if I return it, I have the warranty problem of not serving rooted devices. And I cant unroot it since it wont turn on.
Please some help
Thanks!
After about 30 minutes without the batter inside, I reinstered it and it was plugged into the charger and orange LED went up I turned it on and it turned on
Relieved but....I do want to know the reason behind this just in case next time....My warranty expires May 5 so.....
On that last note, should I unroot it and return it just to get a refund? Scared something like this may rehappen.
By default, on a nightly, it was on the interactive governor when it has always been on ondamand. After reading a description, Ive changed it to ondamand just in case...
No one answered cause this is really common and you would have found hundreds of these threads if you had searched.
Next time it happens:
Take the battery out
Wait 5mins (not 5 seconds)
put battery in
hold the power button for a few seconds
plug in the charger after the screen has light up (NOT BEFORE)!)
Phone will boot and be charging
If that doesn't work, try again but leave the battery out for 30mins.
If that doesn't work you need a new battery.

Nexus 7 keeps turning off at random intervals

This has been going on for about a week or so.
At first I kept finding it off in the morning after charging, and then it became more common. Mostly happens when the screen is off but not always, I've had it turn off twice whilst I'm using it for example. A couple of times it has needed a long press to restart it before it will turn back on. Right now it has turned itself off and will not turn back on.
Battery has never fallen below about 50% throughout so it cant be that. It doesn't get heavy use so I'm not convinced its overheating. I had a look through the app list and none of them seem to be obvious candidates for the problem, and if i cant get the thing to turn back on I cant even test that.
I think this one is going back to HMV asap but I was wondering if anyone has any ideas for me to avoid the problem with its replacement, or if anyone is having the same problem. Its a shame as I've been really enjoying my Nexus.

Hi, I had the exact same problem and ordered a replacement from the play store. I never found a way to fix it, I would recommend you just get a new one from HMV. I hope this helps
This actually just started happening to me yesterday on my 3 day old 16GB Nexus 7. I kept mine plugged into the AC all weekend, and yesterday watched it shut down itself once. Thought it was a fluke and just turned it back on...left it running overnight...pick it up this morning and it's turned itself off yet again. I guess I'll have to return this one before it completely doesn't turn on anymore!
Bah. Thought that might be the case.
2 days off charge (and some time on charge) and mine still wont turn on.
Definitely going back for replacement.
Elsydeon, it sounds like you should do the same. Took about 4 or 5 days to go from irregular to brick.
I seem to be getting the same thing... Once every day or two I pick up my Nexus and the screen won't turn on, I hold the power button and it starts booting up. I haven't had this while charging (maybe because the screen is on while charging??)
For those of you who traded in for a replacement, did this solve the issue for you?
I was getting this, but was using one of those magnetic cover/cases. If I wrap the cover round the back of the N7 whilst using it, the magnet in the case/cover is sometimes strong enough to turn the device off from the back!
Mine has powered off twice now

Just wondering as well like the last guy if swapping for a new one helped this issue.
I actually have looked at the battery data and think somewhere the nexus has gotten a power spike that turns it off but not sure if that definitely is the issue.
If it is, perhaps it's where we are plugging in or a failure with the AC plug?
Ideas? I've attached a photo. I hope it uploaded.
Thanks.

Me too
unless i hear different from anyone here, going to exchange it for a new one today ... only been 2 weeks from Staples.
Actually going through the data, it's happend the last 3 days now.
I wake up to the white battery symbol.
By the way, for future ref, is bootloading warranty killing? I am in the process or restoring now just in case.
Thinking of getting their replacement plan now too because of this episode.
Thank goodness for titanium backup
Nexus 7 32GB Display Keep Turning Off
My Nexus 7 32GB tablet's display continues to turn off at random times also. It happens while I'm watching a video in landscape. But then I stop the video, go to the home screen, and it still turns off. I already replaced one last week and now its happening to my new one. Anyone got answers? I'm going to call google device support today. Maybe if enough people call, they'll do something about it. Their # is 888-836-3987.
Still happens

My NEW 32 tab worked out fine for a night and woke up today to the full battery indicator and tablet off again.
I have a new insight though, somehow the battery temp is rocketing to 100 and I'm guessing that is when it shuts off.
It may be because I am using SetCPU to limit my CPU speed to 300mhz when the screen is off. Maybe the tablet is trying to update all my apps while I am sleeping? It shouldn't use so much power though.
I'm going to try to create a new command to let it use it's whole CPU as long as it's on AC and screen off and see what happens tonight.
Happened overnight again. No insights? Does anyone think my nexus will finally brick sometime?
I don't know anyway of testing what is up with this thing? Thanks.
Nexus 7 Screen Keeps shutting off - Fixed
To those experiencing issues with their Nexus 7 screen randomly shutting off.
I just received one for Christmas, and thought this dang thing sucks. The screen would stay off and only show for half a second when I click the lock button to turn it back on.
The issue what the case. The the case, when folding back, contains a small piece of metal on the click. This little connection, thought not direct, causes the screen to shut off. I've tested it out multiple times just to make sure.
Again the FIX is, keep metal away from the back of the nexus, it doesn't like anything that can cause a magnetic field. Even if the metal is enclosed by something.
nexus 7 screen turns off
For those of you who are experiencing intermittent screen display going to sleep mode or turning off you can fix it by removing your tablet cover. Some third party tablets come with different strength magnets stitched inside the cover. The magnet is used to activate the nexus tablet smart cover functionality. If you flip the cover to the back of the tablet the magnetic field may cause the tablet to think it should turn off while in use. Get rid of your cover reboot your tablet and notice that the screen will stop turning off. Hope this helps.
Hi, I also had similar problems with my Nexus 7. After removing the back of the unit, I saw that the battery was nearly unplugged. I simply popped the connector in and voila! no more SOD, turning off, nothing.
So, the Nexus was probably turning itself off because there was randomly no more power comming from the battery.
Here's a link on how to remove the back shell : http://www.ifixit.com/Teardown/Nexus+7+Teardown/9623/1
Look at Step 4.
That Fixed It!

I was researching before going to get my Nexus 7 replaced today as it also started having this issue. After reading your post, I took your advice and removed the back to find that my battery connection was also barely intact! Thus it would lose power any time it was bumped slightly to that side. Now that the connection is securely in place, I've had no more problems!! Thanks to you StefGou!!!
Hey guys. A few hours ago I encountered the same said problem. I woke up to find the battery was depleted so I charged it. It turned on by itself and stated that I have 6% battery left. As I wait, suddenly the screen was like distorted and give me static sound then shut off. Numerous trials later end up the same. So I just put on the charger thinking to let the battery full. To my surprise, there was no indicator that my N7 is charging. I just leave it charging and left. About an hour I got back it still nit charging. I boot the N7 and it still on 6% battery. So I followed you guys handsomely instructions to remove the 3rd party cover and now my N7 is back. Thanks guys. But I wonder why it is happening now? I've been using the cover since forever.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.
Sent from my GT-I9000 using Tapatalk 2
Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.
