Big Problem with USB

Hi. I moved from a DInc on Verizon to the Vibrant because I hated the sunlight on an AMOLED, and because Verizon was stealing my money. Although honestly verizon just lowered prices, and Tmo's network is still crap in my town.
Anyways down to business: My phone is rooted, and I applied one click lag fix. I am assuming that was when problems started but then again not for sure. I've gone from stock to Vibrant5 to Vibrant6 roms, no change.
The first problem here is this: my phone always thinks it's plugged in to USB. It cycles on an off, but never just stops and stays normal. I'm talking several times a minute ''usb connected'' or whatever on, off, on, off... annoying but no big deal. Except that freaking battery meter that pops up when your phone is off but plugged in via USB starts popping up when it's not plugged in and my phone is turning on... but since there isnt really usb in, it just hangs and resets. The second I plug in a real usb, meter pops up and i just turn it on and all good.
Second problem, which makes it so bad: my phone does this things that I've seen on XDA several times where when the processor bogs down, or GPS is on, or whatever taxes the phone, it will randomly reset once or twice a day.
Put those together and what you get is me, in public away from a charger, with a phone that won't turn on. WTF. So I repeatedly take the battery out and jam the power button till once in a while I'm able to start it before the stupid usb thinks its plugged in. Other times I'm screwed till I find my car charger.
Now, what can I do? Before anyone says warranty, yes I unrooted, did my best to unlagfix, and went to the Tmo store. They ordered me a new phone. However I have to send mine in when it gets and here and would like to insure there is no root related crap for them to find, plus I'm stuck with this phone freaking out on me for another week.

I was having the same problem , but it started since.my dougther put the usb canle in her mouth xD , I just cleaned the contacts and waited a few hours but now is fine , running

cleaned the contacts on your cable, or inside your usb port on the phone? How would you clean those?

Sooooo, no input huh. Okay then.

If people keep messing up their phones by rooting and flashing roms and then, rather than trying to fix the problem, send them into tmobile, I bet future firmwares and android phones will be more like the iPhone and iOS.

First I would try to flash it back to stock and leave t factory. Then if problem persist, its probably hardware. I mean you are returning it anyways so flash it back to the stock rom and do a factory reset

No charge, no sync - loose MHL cable port.

Only had mine 3 weeks and its broken already. I have been using a desktop charger and have not been forcing it in at all, not once, I have always been very gentle inserting it it, anyway it no longer charges, it looks like the connectors have pushed themselves back so they are not flush anymore and thus no longer connecting to charge or sync.
Not happy about this at all, I had my desktop charger for my HD2 for 18 months with no problems at all, this suggest a very weak connector.
!!! BE CAREFUL !!!
Going to call in at Phones4you and see if they will swap it, I don't hold out much hope though.

Wow bad luck man, but really you don't need the F word to express your frustration.

was it an official desktop charger or 3rd party?

DO a factory reset using code *2767*3855#
(please not this will wipe everything including built in memory, so do backup before you proceed. Backup possible by moving content of internal memory to SD card by copy paste in file manager)
I had a problem when my phone stopped charging after I upgraded firmware, It would also launch Connected to computer screen when it wasnt . Thought its dead.
Did factory reset using this code and its working flawlessly ever since. Seems to be some kind of bug which happens out of nowhere as 2 people I know have experienced this after upgrading to KE2.

I was going to ask exactly the same thing...

I think the OP means that the micro usb receptacle has come away from the board and has been pushed back into the body of the phone. I hope this is not going to turn out to be a common problem as it's something that seemed plague to the Nokia N900 and it took ages for Nokia to acknowledge a design/production fault.

great advice, now it wont boot at all, just goes round in circles....
F**cked.....

anyone got any ideas?

Hi, the charger isnt really the issue, i haven't had any problems inserting the phone into the charger, ie no resistance which suggests to me it was week or loose and has gradually pushed it self back over the last 2 weeks since I have had the charger. If thats the case it would have done this with any charger or cable.
Just spoke to phones4you, they are going to exchange it for me, they didnt even grumble after I told them what happened which I thought was odd, heading off now to pick it up.

Will be interesting to see if your wifi is any better on the new phone stoolzo. Maybe you could let us know. Thanks.

good old phones4you
got it already, yes I really have. Phones4you are just round the corner in PC world. Will check my wifi tonight and report back on the other thread.

remove and reinsert battery
i had this issue when running custom kernels. somehow doesnt happen with stock.
issue happens like this:
u go to bed while charging
u wake up and the phoneis off or very hot with battery and temperature warning
u reboot and it doesnt reboot, doesn't boot, just goes in circle battery display/reboot cause it doesnt seem to charge neither have enough power to boot.
removing battery + cable then putting both back = it boots again and charge normally

************************************************************
Yeah, did all the usual things, I have bricked phones before and always managed to turn them around but we have no CMR to flash anything from ROOT/SD so when it wouldn't boot after a factory reset I knew I was in trouble
The MHL port being loose was the tell tale sign of a fault as I hadn't misused it at all. When I compared it to my new phone I got today it was defo a little further back, just enough to prevent it connecting.
Good old phones4you, fault report to phone exchange in under an hour, impressive.
Just in case the charger had anything to do with this I am going to get rid, dont think it did but I don't want to risk it.

Phone stuck on USB/charging... very weird

Hey there. I have my Galaxy S II (GT-I9100) for about a month, and since a couple of days ago it has been behaving very weirdly about USB and charging.
First of all, the phone thinks it has USB connected at all times. When I go to the settings menu try to enable mass storage it says USB is already connected, even though it isn't!!!
Sometimes when I start the phone it goes to that USB Kies screen and says "connected", when absolutaly no cables are connected AT ALL!!!
When I turn the cell off, remove the battery and plug it back in, without turning the phone on, the recharging battery icon appears, but blinks with a drained battery icon with a yellow exclamation sign and a thermometer which I sincerely have no idea what that means.
It also takes ages to recognize the power charger or when I really connect the USB cable. And finally, when I take them off, it also takes a while to "perceive" they're off and remove the charging lightning from the battery icons.
PRETTY PLEASE, SOMEONE HELP ME OUT, as I don't have time to take the phone to service, and didn't really want to do that
Thanks!!!

This has also happened to me and loads of other SGS2 users! Although usually it only happens sporadically and not constantly. It seems that it's a bad soldering job or dust/dirt has gathered in the microUSB port. You might be able to fix it, if you're *really* careful.

Last night my phone wouldn't even start charging, so I decided to take matters into my own hands. With the smallest screwdriver I could find, I carefully 'lifted' the tiny PCB in the USB jack while blowing in at the same time. Sure enough, some sand particles fell out, and I haven't gotten carmode'd in nearly 13 hours now. Previously it would do it once every 15 minutes. So far so good, it seems.

Thanks for the help... but what is PCB? Is it the connector inside the "hole"?

Tried that and it stopped thinking USB was connected the whole time... on the other hand, it doesn't detect when I connect the USB cable

You can't talk on plural when you only point out one thread. And I've read that, but it isn't the same as my phone doesn't go in "car mode".
My phone's problem only resembled a problem JaX3RiR briefly mentioned in the middle of the thread.
I tried googling it before posting anything anywhere, but couldn't find anything useful.
Please don't try to look like a smartass like that and embarrass yourself. If you got nothing to add to the thread, it's best if you sit out of it. It's much more appreciated when helpful people like JaX3RiR post...

Hi,had the same problem,tried reflashing back to original firmware,but still had the same problem,,the only way i could boot the phone was through recovery mode,(reboot)Had to send phone back for possible repair??cut a long story short they sent me a new phone,,They said they couldnt repair the fault,something to do with the usb charging system,,So i would advise anyone with this specific problem,to send phone back,and get a replacement..hope you get it solved

Thanks mate, I sent mine today as well... I hope they act the same with me, as I'm afraid customer service around here always tries to incriminate the user not to use the warranty...

There is no reason to be angry, I'm just trying to help, and just wanted that we all post in one thread, so it would be easier to track later.
I just posted longest thread. Here is another one if it helps to justify:

I'm pretty sure you have the same problem. Sometimes Vlingo starts, sometimes phone thinks its charging, when trying to boot it shows battery image and won't boot, can boot only recovery and do restart from there.
Get of the high horse when people are trying to help you.
Are you sure you didn't connect USB cable upside down or bended USB port with the cable?

I have no idea what Vlingo is, and obviously I didn't connect the USB cable upside down. I don't think I bended the port with the cable since it still recognizes the cable for charging or booting and going directly into Kies mode, for example.
I am not on any high horse when people try to help me, as you could see my response towards the guys above. Your post wasn't sounding helpful at all, you were just sounding like "hey, you dumass noobie, don't open a new thread for yourself, check the forums first".
By the way, I also took a look at that thread you posted before posting mine, but I have no idea what is "car mode" on my phone...

Sorry if I sounded rough. I thought it is similar issue, so I posted link to longer thread. I had this issue myself.
Peace. Let us know what the service say .

This happened to me one week ago while on holiday....that temp indicator while charging plus the other stuff you mention....
Plus the phone went into flight mode and won't come out....
Got home and did a reset and phone now doesn't recognise sim card...
great phone but I'm a little disappointed

Hello,
Had the same problems aswell, only mine had a bunch of other problems aswell:
When I shut down my mobile it restarts itself and then shows a yellow exclamation mark with an tempgage. Only way to turn on my phone is to connect it with the charger, turn of my phone again, remove the charger and then the phone turned itself on again but without the temp gage.
My phone also thinks its charging when it is not, and when I am actually charging it, its not charging.
Also my PC does not recognize my phone so I am not able to update it.
I have also sent my phone for a repair, I will keep you guys posted.
greets from the netherlands

Yep, mine only got fixed by going into service. It got its mainboard warranty switched.

T- Mobile sent me a replacement phone
They seemed to know the symptoms when I explained what was happening

Same fault for me. Mainboard replaced, works fine now.
Sent from my GT-I9100 using XDA App

How did you guys get it fixed? Did you have to ship the phone out somewhere? How long did you have to wait to get it back? What was the process?
Thanks.

Mine is going to be repaired in two weeks.
I was the 8th SGS2 since tuesday which came in the repair center.
The repair guy said it is a manifacturing fault.
The phone gets hots, and outside temperature is cold, so it makes moisture in the phone.
This cause the phones power management to get fu up (SGS2 has a small battery inside of it, and that gets fu up). Only fix is replace hardware, but 9 of 10 times Samsung gives the fault to the customer. They say it has water damage and can't be fixed in warrenty...
I'm going to write a huge article about it, and I hope it will get published by a lot of site's soon. Phones he admitted having the problem: SGS1, SGS2 and SGSN.

I charged my GS2 2x by USB and it's discharged faster than by the sector
The USB power isn't enough for charge up the GS2 correctly

Are you guys suffering from rapid battery discharging, i have all of the above symptons but my battery drains within hours...I`ve even bought a brand new battery off ebay that is exacly the same issues... I`d like to send it back to O2 but i`ve rooted and flashed custom firmware...

USB_OTG - Help Please

Hi Guys
I have suddenly started to notice a process called USB_OTG that is killing my battery. It is taking up to 90% of the charge and I don't know how to stop it. I have tried doing a android backup to a time that this wasn't causing an issue yet it is still there
I can't connect my device to my pc/mac to transfer files and most of the time it won't even recognise that I have plugged a charger in
Can someone please help as this is driving me insane

Turning off your phone, then on, should be enough to get rid of it. It's a known bug of the system, it goes berserk at times after using the USB connection.

I have had this for over a week where i have turned off, done a battery pull and still can't seem to shift the issue
is it possibly kernel related?

Just done full wipe and installed a rom i have never used before and still have the same issue. cant connect to usb, won't transfer data when debugging is on or off. does it sound like a warranty issue and should be put back to stock?
don't want to use odin and increase the counter though

gone back to stock and still having the same error. is my phone officially knackered?

Look into the USB receptacle in your phone. Is there dirt or are the pins twisted and in contact? From what you described, it might be that your Note thinks there is a USB device connected, and that might stem from some kind of contact from pins...
Ernesto de Bernardis
[from my Galaxy Note]

USB on the go mode is when your phone is trying to change from a USB "slave" to a USB "host".
A normal phone should always be in "slave" mode, that is when you plug it into your computer you can do kies and all that stuff.
If you plug in a special cable, your phone will detect this and try to go into "Host" mode where it can connect to a USB stick or a USB mouse.
This special cable works by shorting two of the pins on your USB connector together that normally aren't shorted.
So in short, with what you describe it appears that dust, corrosion, or debris or other hardware failure has caused the phone to incorrectly think those pins are shorted together when they are not.
Look at it under good light and magnification. Clean it with alcohol. Good luck.

everything looks fine, can't see any debris or damage on it. don't think the usb will be covered under warranty either looks like i may be phone less

If you are desperate and it is not covered by warranty, you should in theory be able to open up the phone and cut the trace / wire that leads from the ID pin back into the USB chip. You would lose OTG capability forever but it would solve your battery problem.

Why? USB OTG is an advertised feature, so I guess should be covered by warranty.

i've also run into this problem. Phone wouldn't be able to go to deep sleep after using usb otg. Turned the phone off and back on fixed it. Kind of annoying.
running franco 9 on checkrom 6

I had this problem as well. Cleaning and pushing pins were only temporary fixes for me. And it just got progressively worse after awhile. So I went back to the place I bought it and they sent it in for service. It was covered by my warranty apparently, one week later I got it back, fit for fight. Remember to go back to stock though

Not sure if this link will work since I'm a new member here, but you could try this :
add a http here: forumDOTxda-developersDOTcom/showthread.php?t=1329360. Disregard this link if you didn't use that method to root it though. As you might suckerpunch your phone into oblivion
Also, I cleaned the usb port with alcohol/Nail polish and a toothbrush to temporarily enable it to connect to my computer(Let it dry for at least 20 mins after). I am no expert at any of this though, so before you trust too much in my advice, you should go search around the forums for confirmation.

Any more ideas how i can unroot as my phone wnt connect to a PC via USB so need to do it all on the phone. Think I am screwed

N910F - strange issues with charging

Hello everybody,
- On monday i ran into a strange problem with my N910F. At first it was just not charging whatsoever.
- after the phone ran out of power, i attempted to charge it which gave me a brick with a black screen, vibrating short every two seconds
- Fine by me i thought, went and got a replacement battery (after checking simple stuff like the physical state of the battery (normal) and killing the batterystats (which i heard both yay and nay about so i decided to give it a try).
- Replacement battery charged overnight on the USB Port of my computer (2.0, for the completionists) went smooth (didn't turn it on, just had this bubble animation of charging).
- Turned it on this morning (booting apparently took 3% off my battery) and all well so far.
- finally in my chair at work i plugged it into my power cable (genuine Samsung FastCharging adapter that came with the phone itself) and nothing happened
- tried another adapter (some cheapo 1A adapter) which started charging around 10secs after connecting but decided to stop charging after a couple of minutes
- some shaking and gentle knocking brought back the charging symbol for some seconds, seemed like some loose contact or a broken cable so i felt fancy and plugged the very same cable (the one originally shipped with the phone) to my laptop. started charging instantly and no shaking or knocking stopped this (so no loose contact or broken cable at all)
This is the story until now, put together as complete and organized as possible. For now i'm stuck to charge my phone on the laptop or computer which seems to work. In this progress above i tested around 7 chargers, 3 laptops, 2 computers, 10 cables and 3 screens with both batteries, although the workaround i have now is only tested with the genuine cable as i was just done with testing for the night.
Now for my questions (apart from a touch with the magical fix-everything tool):
- What i see as possible causes based on my very shallow knowledge are either the microUSB port on the phone or the power distribution unit. Anyone has an idea what to check?
- As i have no idea how deep the OS goes, could it be a software issue by any chance?
Even though the device is only ~9 months old, I don't like the idea of going through Samsung for this one as i tripped KNOX already.
Hope there's still hope for me
Cheers,
Fachtal

sooooooo, does nobody have an idea lying around somewhere?

I tried around 7 adapters (from cheap ones to genuine galaxy S3, Note2, and Note4), around 10 different cables (again, from cheap ones to genuine samsung cables), 3 Laptops (again with all cables), 2 computers (all cables) abd one of those mobile charging battery things.
The only thing that works is either the genuine cable on my computer or the same cables on my screen at work.
@geevh that's news to me. As far as i heard is tripping know equal to losing warranty.

I just flashed the official ROM using Odin. Had some problems getting the phone connected while in DL mode (didn't work at all while in normal android mode).
This seemed to be a dirty flash (already was on stock Rom, just put CWM on, rooted the phone and replaced the kernel to have SELinux permissive for Viper4Droid) as it didn't go through the setup process and was like before.
Anyway, charging still doesn't work. Is there anything else I can test? I'm nearly at the point where I migrate back to my old SGS3 and have the N910F sent to the carrier (well, in the end it will go to Samsung) to get it fixed.
Thanks about the whole Knox false knowledge.

I would just give the device in for repairs but make sure to flash a full stock rom and factory reset before giving the phone, since you have already tried everything else.
Good luck

Well, flashing stock ROM seems to be slightly less relaxing than I thought. It feels like I have to connect the phone to the pc, put it on the table in a very specific position/way and then hope that it doesn't disconnect halfway through flashing...
This has become quite an adventure so far and I hope I'll get this done so i can get rid of this very expensive paperweight
Thanks for all the help so far, I guess I'll add the explanation from my carrier/Samsung as soon as I (hopefully) get my device back.
Fachtal

PMIC or Charging IC is probably broken on the mainboard, i hear more N4's have this problem.
Best is to send it for warranty or let the components be replaced by a "good" repair shop.
Most service centers don't check knox status so i would go for that, if all fails take it for repairs if the costs are not too high.

Hi guys, back for a rather unexpected "solution"
When i finally freed up some time to actually get to the carrier shop to get my phone fixed, I was in for a rather embarrasing experience.
The lady in the shop pulled a charging cable and an adapter out of a box, plugged my phone in and it suddenly charged as if nothing ever happened. Now, some time later, it still works perfectly fine, as if there never were problems...
I have absolutely no idea on what happened. Before going to the shop i obviously flashed the stock rom yet again (with the usual wipe user data/cache/dalvik procedure).
Now, on what i had when the problems started: stock BOC5 ROM, touch CWM, rooted and with a custom kernel for SEAndroid permissive (emotion something i believe the kernel was called). Now during my rather extensive troubleshooting I actually flashed the stock ROM at least once and the issue persisted, which is why i just stood there, staring on my charging phone, my jaw somewhere on its way to the ground, unable to form any proper words :silly:
So basically, does someone have a possible explanation to clear this up? If not, I'll consider this thread solved i guess^^
In the meantime, I downgraded to Stock 4.4.4 with CWM, root and xposed (which i really missed on Lolli) and I'd say I'm happy with this :victory:

Hi guys, back for a rather unexpected "solution"
When i finally freed up some time to actually get to the carrier shop to get my phone fixed, I was in for a rather embarrasing experience.
The lady in the shop pulled a charging cable and an adapter out of a box, plugged my phone in and it suddenly charged as if nothing ever happened. Now, some time later, it still works perfectly fine, as if there never were problems...

It's sound strange but a couple of years ago i read somewhere,forgotten where and about the specific device. The thing was that phone wasn't charging eather ,and now it comes.....the solution was turnig around the charger in te power socket.

this indeed sounds strange. And honestly, i didn't pay attention on the orientation of the power adapter (although my stock samsung one is always in the same orientation because the cable goes out on the side (which means it worked in the same direction as it didn't before).
The only even remotely considerable approach would be that the custom kernel along with this synapse app somehow screwed with the power intake and i forgot to wipe everything when i first flashed stock over it, meaning that synapse still had its fingers in the system screwing around with that.
But then again, as I seem to be the only one with this problem and this custom kernel had more than just a few users I don't think this is the way it went (I don't even use an unusual collection of root Apps which could cause some sort of malfunctioning combination of effects).
I had a few evenings just thinking about this and draw some simple mindmaps/schematics to make some sort of a sense...
