Develop Bugs

[Q] Sleep of Death on GN

Has anyone else experienced this on the GN?
I've had this happen twice in the two weeks since I got it.
The device is stock.
The only common thread I can think of is that in both instances I had plugged the phone into my PC via the USB cable.
I only use 3 sources to charge, my PC at home, laptop at work, or wall charge overnight.

Meh, it is the Nexus (tame dev device). The S was way more unstable. Just pull the battery and all is well.
If you want to be cutting edge then you have to take the rough with the smooth.

Never happened to mine. You might have a buggy app that doesn't play well with ICS.

Thanks lads, I'm not massively concerned, and yes, it may well turn out to be a bad app, was just posting to find out if it was more "common".
I have of course just seen another thread in this same forum dealing with the same topic (funny that my post flagged up a bunch of other threads in unrelated forums), so this'll probably be closed down...
Think I'll go wade into that other thread now

I've had it twice since I got mine, wasn't plugged in both times so for me it's not down to charging.

mine reboots everytime i try to use the picture frame widget. i select the pic, then it reboots.

The day I got my phone, I had 2 SOD's.
This morning after I woke up, it was in a SOD and 2 minutes ago, the screen went off and I had to take the battery out.
Really strange
Someone have a solution?

I noticed this issue too, whether charging from the PC or the mains charger once the phone hit 100% on the battery it would turn off and could not be started without pulling the battery. I read somewhere that resetting the phone could cure this so, as much of a pain in the ass as that is, that is what I did. SO FAR this seems to have worked for me. I was charging the phone via the USB cable to the PC yesterday and no shut off and when I went to bed last night the phone was on charge all night and again when I woke this morning all seemed good. I'm not sure if this will work for everyone suffering this issue but it worked for me (for now) so thought I would share my experience.
Good luck !

This is so weird, hasn't happened to me since that day. I was able to reproduce the issue after reading another thread on battery saving. Someone mentioned limiting background processes to 3 in Developer Options, when I did this, my phone SODed within seconds. Twice!
Think I mentioned this elsewhere and someone said he used that option with no problems so it's clearly inconclusive. I'm just going to steer clear of that for now.

This has happened to me a number of times, usually when I was multitasking while listening to the Google Music app. It's a good thing that back cover is easy to pull off and put back on.

Galaxy Nexus Won't Charge

Hey Guys,
Over the last year or so I've had intermittent charging issues with my Galaxy Nexus. About 4 months ago is when it first started happening, the phone would either not charge or only charge when it is turned off. Somehow the issue was resolved through tons of troubleshooting, I'm not even sure what fixed it or why it started working again.
Same thing happened about 2 weeks ago, except this time it won't charge at all. Then 2 days later all of a sudden started charging again. Now it's happening again today, I have no idea what is going on or why this handset won't charge properly. The phone won't turn on with just the charger in and the battery out either.
I've tried various chargers including the OEM charger, I've tried up to 6 different chargers and 7 seperate micro-USB B cords. Nothing. I've tried a brand new battery that a friend bought for his phone before he threw it in and no results.
At this point I think it's the USB charger board, however I'm not sure why it would not work and then work again. Does anyone have any ideas or any solutions? I've read thousands of threads on this, from this forum and many others and have gone through some ridiculous troubleshooting methods.
SCH-I515 Korean Version.
Seriously, anyhelp is appreciated.

As of now, all of a sudden it will charge while it's off. But only to about 4% then it just stops charging. It will not charge while it is on at all.

Because it's getting worse and worse?
Relock bootloader, and return it in for warranty, if you can. I'm afraid there's not much help if you already checked for damage to the USB port.

hi
had the same problem until a few minutes ago.
received my usb/charging flex part today and changed it just before to post here.
took me like 20 min, really easy to do, everything works perfectly and i also took time to clean up a bit the phone inside of some dirts and change the housing i bought with the flex part.
As my screen is under protection since the beginning (4 months old), and that i recently bought a 2000mah battery, well i have to say that i have a new phone ready to handle the new year easily!
operation is easy and you will find plenty of videos on youtube showing how to change the usb flex (7€/$ , +/-) so pretty cheap.
Good luck

Why not buy an external battery charger and a spare battery?

I'd get a replacement daughterboard and switch it out yourself. It's easy dude, just like a previous poster already said. I just did it myself, took me all of 20 minutes and cost me $10. ifixit.com has a step by step direction sheet, if you have any questions feel free to contact me about it.

Try the following:
1.) Turn off your phone.
2.) Get a flat head screwdriver (small one)
3.) Push the flat connector inside the microusb port up. (It often gets bent downwards because it's so thin compared to other phones...)
4.) Boot into the bootloader
5.) Hit volume down until restart bootloader appears. Press power button.
6.) Start phone manually.

i dont know why, but this fixed it for me, for a short while. now the charging is intermittent and seems to come and go as it pleases.

Hi,
I had the same problem of ghost charging, it started with phone not charging when connected to charger and then randomly showing charging...
Now discovered it causes vbus_tuna_otg wake lock, resulting in high system usage in settings> battery and not letting phone go to deep sleep, causing battery drain.

Same Problem
I've come into the same problem with my Galaxy Nexus as well. If my phone is turned on, my phone will recognize that a charger is plugged in but the battery will not charge at all. If the phone is off and plugged in, the charging screen won't appear. I've tried multiple chargers and cords, 2 different batteries, and even replaced the micro usb and board, but the problem hasn't changed at all. I've managed to charge my batteries with an external charger but would like to get my phone back to normal working condition. Does anyone think that changing the actual motherboard itself might solve the problem?

I had this problem before, using something small and flat to push the charging connector off the housing will work for awhile. The pin in the charging port is bent down and is very thin it's easy to lift up just use a tiny bit of force to lift it up. The pin touching the housing is causing a short and that is causing your no charge while it's on and mine even went as far as draining my battery very quickly. I did research and found alot of people having this issue on the gnex. I eventually had to turn mine in for replacement, no problems since. Hopefully yours is still under warranty or you can buy the peice that is broken and replace yourself, there is a post above saying what to do for that.

Looks like my phone developed this problem. It sometimes won't charge be it via my pogo dock or USB cord. It seems to start taking a charge after I pop out the battery and then put it back in. I'm going to order another battery and see if that is the problem.

Thank yoiu!!
solved my problem!! I am in your debt

popping the battery out just worked for me too

I just did the remove battery trick as well and it worked. I just noticed my battery not charging yesterday but figured it was because I was trying to use a different charging in my dad's car. got to work where i left my normal charger and no luck.

That's good, I tried it a few times but the issue still pops up. To be fair though, I've had this phone and battery since launch day... Almost three years old. I ordered a new battery so hopefully I won't have the issue anymore... And I won't be surprised if my battery life is a little better too.

The Galaxy Nexus is nowhere near three years old. Your phone would be 18 months old if you had it since launch.

Excuse me, two years. According to Samsung their lithium batteries have a life of about 500 cycles. So my point is still valid, my battery is probably just on it's way out. I'll find out for sure when my new one comes tomorrow.
Sent from my Nexus 10 using Tapatalk 2

Yeah, since battery life hasn't exactly been the strong point of the GN and some of us had to go though a complete cycle daily, I suspect a lot of folks are going to be seeing more and more issues. Not too long ago, I had a battery that failed in such a way that it would randomly crash the phone and had to be pulled in order to allow a reboot. I would've suspected anything but the battery in that case.

This kind of worked for me, but the "boot into bootloader and restart it" killed my phone, don't know why. After a lot of a hassle i got it on, with 2% left, again not charging...tried to repush the connector towards the center and now i cant get my charger into the phone, maybe overbend it...what to do?...

I have a strange problem, my Gnex does not charge the battery, first i thought that it was the battery so, I tested the battery on other phone and it charged just fine, and then i ordered the usb/charging assemble from ebay and replaced on my gnex, and still not charging the battery, but when i connect the phone to the pc it recognize it immediately, but still won't charge the battery, anybody has an idea of what my problem is?? and how can i solve it?
Please help!!!

Not charging

Last night my phone died after 2 days off cable due to me having to use my cord for another device. I plugged it in today to find that it wasn't charging at all. I decided to give it a few minutes before trying, thinking it may not be turning on because it still needs some juice. I waited 30 minutes and it wouldn't turn on still, just gave me the little animation of a battery draining to indicate that it needs to be charged. After this, I figured that it's possible the cable is just dead, so I opted to borrow a cable from my brother. The cable charges his phone just fine, but it doesn't work with charging my phone. I took a shower while waiting for it to perhaps get the juice it needed, and still no dice. I tried several different outlets thinking perhaps the outlet was dead, and still nothing.
I've had the phone for a little over a month, so I'm not sure how long I have to turn it in or not; I'd hope it'd be 3 months for factory issues, but judging from how people mention 14 days, I'd assume that they're eager to push responsibility of broken devices onto the customer as fast as they can. Do you guys have any idea of what could be wrong? Perhaps if it's possible for me to get a replacement at this point?
I've been running the Lifeless v.11 Rom for a while with no issues, I haven't flashed anything in possibly a week or two, so I honestly doubt this is a software issue. It's never been exposed to water, but then again I really don't trust phones to detect if they've been damaged or not since it seems even a humid day is enough for those small water damage detection stickers to run pink.

Pull your battery, try again

Yea, going to update this. Sprint was giving me issues and trying to cough up money from me, so I pulled the battery and cleaned the port with a q-tip and it charged fine again. I was in for a scare there, but it's back to life.

Same problem...didn't have to pull battery

Just wanted to chime in with my experience.
I had same issue. Battery completely drained with a visit to the relatives (low cell signal).
Got home and plugged it in for 5min, the "battery charging" animation came on when short pressing the power button.
Had to move the phone to a different charger for the night and noticed that I couldn't get it to even show the charging animation while on the charger. Indeed after 8 hours on the charger the next morning it still wouldn't turn on. I thought I would have to take it back to Best Buy. On a whim, I thought I would drain all of the capacitance from the system by pressing and holding the power button to see if that would allow it to restart the charge cycle. So I held the power button for about 30-45sec off the charger, then waited about 30min and plugged it in at work.
It worked. Not sure why, but I didn't have to return it to Best Buy, so I'm happy.

[Q] Ghost Is Using My Gnex!!! Help!

Okay, gonna try and explain this as best I can, bear with me.
2.5 years ago or something I got a Gnex from Verizon, brand new. The phone would act like a ghost was using it, like someone was interacting with the touchscreen. It'd randomly call contacts, send texts (random letters/numbers), all kinds of weird stuff. Video of it on day 1 HERE doing this. Took it into Verizon, got a new replacement. Never had the problem again. 2 or so years go by, not a single problem, unlocked, flash, all that, never had the problem again.
About a month ago, I upgraded to a Moto X and passed this phone on to a family member. At the time was running the latest stable Cyanogenmod ROM, the last for JB. 10.2 maybe? Anyway, that's what ROM was on it, again, no problems. Factory reset the phone to wipe my stuff, left it rooted and unlocked. I gave them the phone, battery, extended battery, and a few cases as well, no charger cause I know they'd twist up and destroy the factory cable. Setting the phone up for them battery starts going low, used their charger. Cable had shorts and crap, scavenged around looking for good charger. Get phone set up for them, and I'm done, handed off.
A day later, they're complaining that the phone is going crazy, like a ghost is using it, and it's randomly calling people, sending texts, opening menus, not charging, etc. Sounds like EXACT same issue I had with my very first Gnex that I exchanged. Figured that was really strange, maybe it was the software. Factory reset to latest factory image 4.2.2, lock BL back up, completely bone stock. Re-setup phone and all that jazz. Phone's acting fine. Decided this time that'd I'd let them have the original stock charger, thinking maybe that'd help with the charging issues too. All seems well....
However, during the reset and all, and after re-setting up the phone, battery is low.... plug it in with a known good charger of mine, but not stock original, and all the sudden the phone's freaking out again. Turn screen off, turns itself back on. Dialing people, opening apps on its own, etc. Figure maybe this Gnex just won't take any charger except it's original. Pull battery, reboot, phone's fine, fine for 10+ minutes. Plug in OEM charger this time, wait a few seconds, unplug, phone goes crazy.
Also interesting, they brought another charger of theirs with a little red LED on, plug it into wall, red LED comes on. Interestingly, if the charger is unplugged from wall with red LED off and I plug it into the phone.... the red LED on the wall charger turns on... that's not right. So.... here's where I'm at now. If I pull battery, reboot, and never attach a charger, the phone acts perfectly fine. The instant I plug in ANY charger, it'll start going wacko and continue to until I pull battery and reboot. At first I thought this was a charger issue, but now... I'm thinking it's battery related. This little experiment of getting the phone to go crazy after plugging in a charger applies to both the OEM and extended battery, regardless of what charger I use.
When I owned the phone, I almost exclusively used the OEM charger, occasionally another charger I had that I know works fine. Gave Gnex to family member WITHOUT a charger, so they were forced to use who know what condition phone charger. I'm wondering if maybe some rogue jacked up phone charger with shorts in it and crap somehow killed the extended battery. Then, they switched to the OEM battery, and again, unknowingly killed that battery too with the same crap charger. So maybe buying a new battery would fix the issue and only using the OEM charger from now on or the other one that was mine that I know works? Or maybe the phone is just broken now? It just doesn't seem right that plugging a phone into the micro-USB should turn ON the red LED on the charger when it's not plugged into the wall, like the power is coming out of phone and going into the LED...
I just refuse to believe that on the exact same day and within hours of me upgrading to a Moto X and passing on my Gnex that had worked perfectly for 2 years in my possession somehow just happens to "break" or "go bad" on its own. Thought it was software glitch/bug in CM, no. Thought it was incompatible charger, no. Maybe the batteries are bad? Maybe the phone's circuitry got jacked up too? Just seems weird that, as far as I can tell, pulling the battery and rebooting fixes it for good until the battery dies. Within 30 seconds of connecting a charger, the phone goes bonkers.
Any ideas? Feel bad, family member probably thinks I dumped a bad phone on them!
Thanks!

What kind of sorcery was that? I honestly don't know what to say about this other than bad timing? I highly doubt a ghost is possessing the phone.

I know a ghost isn't possessing the phone, I just, that's how I best described it when it was going wacko by itself. Plus, interesting topic title, maybe get a few more people to read it and maybe offer some advice or info or something :laugh:
However, I do have a ghost in my house, or a spirit or something. I've seen him, sitting on my couch before. He died in a fire, smoke inhalation, no smoke alarms in the house. House was sold, completely rebuilt, and I am first to live in it since then. Crazy story for a different forum lol

From what I can see, it's just that the screen isn't working properly because of leaked currents from the battery or the charger... Just get the whole screen replaced (it's hard to only replace the glass layer) and should be fine.

Leaking currents, had it happen to me before from a bad charger. I doubt it's the battery, try an outlet in a different house, they may have bad power.
Sent from my Galaxy Nexus using Tapatalk

So this "leaking currents" problem, it's a problem with the battery? A problem with the phone, in particular, the screen? It definitely sounds like a rogue bad charger could have done this based on the feedback so far. The "damage" or whatever happened at their house. Just the other night, they brought the chargers and phone and stuff to my house, a different house, problem persisted. So I'm not thinking it's a dirty power issue or anything.

...and so you should have the screen replaced. I've had Motorola and HTC phones with issues responding to touches when charging, and replacing the screen largely eased the problem (although I still ended up getting a new charger because I don't want it to also damage the newly replaced screen).

Could be the battery, could be the USB cables or chargers, could be the USB port on the device, could be the screen. The fact that it only happens when plugged in but with more than one charger and battery makes me suspect the USB port on the device. From my understanding you can buy a replacement. A temporary fix would be to use a charger that charges the battery outside of the phone.

No ghost... i think
I think its because the charger you use....
I had the same problem, but not with gnx... before gnx I used galaxy i5801...
when I put my mobile in charge, my mobile did some crazy things, like operating itself,...I figured out that the charger I used is not the one I shouldn't use.
every mobile has a charging limits, like voltage restriction..
little difference in voltage could make big difference.
so I changed the charger. problem solved for me.
other than charger.. there are some things can do this, I don't know about all.
I doubt it may caused by your digitizer...maybe is has too much sensitivity, caused by water, dust, pressure, etc....
digitizer and display are not the same.
I faced this one too ( galaxy i5801) before charging problem, but not with gnx.
A digitizer is the part of a touch screen that senses your touch and "digitizes" your gestures into impulses that the phone can understand as commands.
if it continues my last suggestion.... call the priest

Well, I borrowed an OEM standard and extended battery from a friend, neither fixed the problem. My friend did say that similar to my first Gnex, when he first got his, it did the same exact thing, but after a while it stopped and it hasn't done it ever since. I also narrowed it down, or, widened the issue, in that it's not just AC chargers, the exact same stuff happens with a brand new 12V car charger.

Dirty power on the fifth rail of a USB wire. Its either the charger not supplying enough power or a damaged cable.

My vote is on the screen, due to the digitiser. Replacing the touchscreen could help solve the problem. I was in your family's position when I got a used Motorola Cliq from a friend and the battery was all good, no leaks. Ghosts just started touching it everywhere like a crazed groupie when it went into my possession. No explanation as to why it happened and I didn't look into it that much but replacing the screen is the most likely solution.

[Q] USB port damage? Causing it to think it is always charging

Okay, this is a weird one that I researched and researched on the web. I think the problem is somehow related to the USB port. It would seem that my handset thinks it is always charging. I should qualify that statement by saying that with the handset unplugged from the charger and checking the SETTINGS > BATTERY stats it says "0 seconds on the battery" presumably meaning that the handset thinks it has a freshly charged battery and no time has expired since removal of the charger. However, it knows it isn't charging because it also says "89% Not charging". The other weird thing is the handset doesn't screen timeout when unplugged from the charger. That is, I have to hit the lock button to turn the screen off otherwise the 15 second delay doesn't work. I've also checked the developer settings to verify it isn't set to force the screen to stay on. However, the 15 second screen timeout delay works perfectly when the handset is plugged into the charger. After 15 seconds the screen shuts off and the red LED charging light comes on. Lastly, with the handset sitting idle with the screen black if I receive a phone call or text message but just leave the handset sitting there the screen lights up but it never times out after 15 seconds.
Any ideas if this is a USB port problem. I know it sounds like a firmware problem but I've checked just about everything you can think of. I've gone as far as to root my phone, backup all my stuff, then re-flash JellyBean. Speaking of USB port. Has anyone changed one out on a S2 Epic Touch 4G? I know that other S2's have a USB flex cable assembly but I can't seem to find one for this particular handset.

I had a similar issue a while back. All I did was clean out the gunk built up in the usb port with a wooden toothpick and the issue any away

I had tried the toothpick trick that you and others had recommended. In fact it did make a positive difference but I still noticed there were still some strange things going on. I went back a second time but this time with a sewing needle and some magnifier glasses and picked it clean of lint and other junk. Of course with was done with the battery uninstalled. I think I'm back and up and running. We'll see if any of the problems come back. Thanks!

My aunt has a device with the exact same problem. It goes doo-doop like you connected the charger. And you can't turn it off ever because it gets on again. Did you fix it?

Using the toothpick/needle trick went a long way towards getting it to behave properly. Like you said, it was doing the "do-doop" thing intermittently and sometimes it would go into and out of charging mode so fast that unless you were astute you wouldn't have realized that what it did. To figure it out I went into SETTING > BATTERY and observed that the "discharge time" on the battery would typically stay at 3 seconds which told me the phone thought it had been plug into the charger.
For the last two days it would seem that I have fixed the problem. After you carefully clean out the USB port of lint and junk with a toothpick and a magnifying glass or readers you may also want to consider getting a can of compressed air to blast it clean. I'm talking about the kind of compressed air sold at Walmart or Office Depot that is used to clean electronic equipment to blast the dust away.
Let us know if you get it fixed!

I don't know if cleaning the USB port had an effect on battery time but I'm getting relatively awesome battery performance like I've never seen before. After 12 hours and very light use the cell phone still has 81% battery left on it. It used to be sitting at around 30% by this time in the day.

think im having this problem. thinking its a damaged usb port. old battery everytime you stick the battery in or plug it in it thinks its charging. new battery i just ordered does the same too. its still charging so ill see what happens after but i say charging port probably?

I went through the same exact thing...ordered a new battery thinking the original battery was at the end of its life and causing the phone to behave strangely. With the new battery in place the craziness continued. I was thinking the micro USB was damaged and needed to be replace which BTW isn't an easy thing to change out like some of the other Galaxy phones because the S2 uses surface mount solder connections. You'll need very good eyesight and professional soldier skills to do it right without effing it up. Luckily, doing an extensive cleaning of the USB port fixed the problem. You wouldn't think lint would be conductive enough to cause a problem but alas, it does. Use a toothpick and compressed computer cleaner air with the battery removed when you clean it.

I'll have to try with the toothpick later. It's weird when you go into setting and look at battery it knows when it's on charge and when not on charge. But soon as you put a battery in, it turns on by its self but to the charging screen and can't be turned on unless both charger and battery are in.
Will the battery percentage read accurate still I wonder?

Yup, that is exactly what I saw when I was having the problem. Basically what that screen shot is telling me is 13 seconds ago your cell phone made the "doo-doop" sound as a temporary short within the USB port fooled the cell phone into thinking it had the charger plugged in but just as fast as it thought the charger was plugged in the temporary short went away. In fact the "short" may have come and gone so fast as make it so that "doo-doop" isn't even heard. The key here in recognizing the problem is that while your charge may have been unplugged for hours you'll note the number of seconds that have gone by since the cell phone thought it was charging will be somewhere well under 60 seconds or at least that is what I experienced. I have every confidence that you have the same exact problem and you just need to thoroughly clean that USB port of every speck of lint and dust. Also, make sure your charger USB is clean and lastly make sure none of the pins on the USB connectors is bent and that that middle portion on the cell phone USB is right in the middle and not bent up or down in any fashion.

How did that happen?
BTW, don't forget...if the phone doesn't seem to want to power up hold the VOLUME UP and the POWER buttons at the same time for 15 seconds until you get the reboot option.

I'm in the same boat now [emoji22] Just happened a couple nights ago... Phone is plugged in but not charging. Not that big a deal, as I just got some spare batteries and external chargers. But now I've got to be super-cautious when flashing stuff, as I can't just Odin back without working USB

That's what I'm stuck doing now. I'm not gonna be switching roms anymore lol. Had to buy a universal charger for the battery

I had this issue with mine as well. At first it seemed to be the recovery but I reverted to stock unroot and it still happened sometimes shine blue to make it think it was completely charged I know this phone had a lot of hardware issues. And then I took it apart cleaned it and what not. It still happened. So after some time it just stop happening and functioned normally. I am unsure what the problem was or why it happened. The whole time I really couldn't charge my phone at all unless it was by computer only
