USB connected issues

I am looking for feedback on a usb issue I have had on two mesmerize phones. For no reason my phone will start showing "USB Connected" in the notification, and the usb storage screen will start popping up. My first phone it would do this, but also would show it charging when not plugged in, and when you did actually plug it in to charge it would show it was, but wouldn't actually charge. The second phone is only a couple weeks old and has started the usb connected crap already. This phone charges properly and all, but randomly pops up the usb connected message. It doesn't always stay showing it either, it keeps popping on and off like it is being plugged in the unplugged rapidly.
Has anyone else had this problem or know someone that did? US Cellular sent the first one in on warranty with barely a question asked, but this second one is so random it didn't act up while I was there, so obviously they aren't going to replace it yet.
One more question to an experienced developer out there. Is it possible that this could be a software issue on the second phone? I ask because the usb port works perfectly when I need it, but it also thinks it's working with nothing plugged in. Thanks in advance for any help/comments.

This is happening on stock? I haven't heard of this issue at all with any of our rom's, so you could be just very unlucky .

Do you close the little dust cover foe the usb port when you're not using it? Sounds like an intermittent short on the usb terminals, fooling the phone into thinking its connected. I'm super anal about closing the cover on mine as soon as I unplug it.

galaxy s 2 acting strangely, battery drain and randomly going into driving mode

I got my sgs2 about a month ago and its been like a dream, battery lasts for a long time phone runs ultra smoothly no glitches and nothing weird has been happening, but these last few days its just been really weird.
1) it started randomly going into driving mode, i dont even know how to activate it or what it does, but i think its draining my battery
2)When i was watching a tv show on my phone it thought that there was an hdmi cable connected and wouldnt let me hear anything through my headphones. i exited it several times but it still though there was a cable connected. Then i went straight home and quit it from the task manager and it worked with the headphines but that might have been a coincidence.
3)When i connect the charger it takes a while to realize that its charging and sometimes stops charging and says that the battery is too hot or too cold but when i feel the phone it feels completely normal.
4)When i connect the usb cable, other than taking a while to realize that its connected to a charger it doesnt realize that its a usb so i cant transfer files with my computer which i do often
5)I pressed home before and it took me to some sort of clock which i imagine is for a dock but i have no such thing
6) Even after using the phone for a while and using several apps the android os has used 59% of my battery, when usually its the display that uses about 30 or 40%
none of these things had happened before and now they randomly started all at once, i havent downloaded any shady apps so i doubt its malware
any ideas?
thanks

Are you using a stock firmware or custom?
Have you tried resetting back to factory default?

seems like majority of your problems are linked with the micro USB port, try resetting your phone and see if that helps. This is weird though.
It happened once to me on my sgs but that was because I inserted the charging pin without realising it was wet but it went back to normal a few days later and I changed my charger.

i was also starting to think it would be a micro usb problem,
would a factory reset fix it?
if so how would i back up my apps so that i have the same apps with the same progress on them, is it even possible?
or should i just wait and see if it goes back to normal?

I am also having this issue now. I've tried a factory reset with no effect. The phone is now largely unusable. Did you get a resolution? If so, how?

im having the same problem too .. wish it's just a software issue!!

the problem solved itself after a couple of days, i took out the battery and left the phone alone for about a day and after it worked fine again, not sure if it was the time or leaving it without battery but its working normally again

I'm having this exact problem - phone switches into driving mode, then says MTP is connected - then it switcheds to a strange lock-screen I have never sen before. It's really strange. I flashed a nandroid backup from a few months back and still the problem is there. I'd flash back to stock and send it in - but I can't connect to Odin via USB because of the problem. Is there anyway to convert a Stock rom to a CWM flashable file?
I'm desperate to get this sorted.

Experiencing the same. Has anyone a proven solution for this?

My phone, sorted itself out - should I say my wife sorted it out - by mistake. What I think she done was hold down the home button, and then pressed the power off button together and held them untill the phone switched off. When my phone came back on again - she had somehow removed the -Exclamation Triangle of the kernel counter and removed the problems from this post - that I'd been experiencing for abouyt 5 months prior.
Go figure - I now have a SGS2 that works beautifully again and has also had any kernel counter and Custom Rom flashing notifications removed altogether. I wish I knew why this worked, as I'm sure their are many who would like to remove the Triangle without a jig.
The other option that seeemd to work for other people was to clean the MicroUSB port of the device with a dry, clean toothbrush - though this did nothing for my problem. Good luck -I know how frustrating it is.

Help Please
Guys, I am Facing the EXACT same problem.
1.Driving mode on/off automatically
2.Showing a lockscreen which shouldn't have existed on this planet.
3.Hanging up unconditionally. Have to restart phone.
4.Sudden "mtp connections" and because of that "Media Scanner"
I own a Galaxy note just 1 month old! I was so angry that i wanted to sell this. But i couldn't adapt to any other smaller screens so, guess ill try fixing this.
1.It definitely is something related to usb port (Since i cannot charge my phone, i use an external charger)
2.Took my beloved to a samsung service centre, they said phone is waterlogged and showed me the motherboard, saying"IC MIGHT be damaged"
3.Cost for repair - $200
4.Cannot afford that. I am guessing they were bluffing cause i saw the shiniest motherboard ever
5.Please fix this, or ill be stuck with a Nokia 500 !!
6.I can, however afford changing the usb connector, anyone successful with that?
Edit: Did my homework and found out that its definitely a usb port problem. Solution:Clean the usb port. Ill try try it and get back to you ppl. Oh and about 20% of the world's population is facing the same problem.
Edit(2): SOLVED!!!
1. Turn Off phone
2. Remove battery.
3.Take a Brush with hard bristles(Toothbrush/Artist's Brush)
4.Take a pin.
5.Take your own sweet 15mins to perfectly clean the micro usb port using the brush. Nicely and Tidily, give all possible strokes to flawlessly remove any dirt in there.
4.Then take your pin(Be careful here) and gently insert it into the gap between that small metallic micro slab and the bottom part of the usb Connector and gently move it up, VERY GENTLY!!!
5.Clean the battery's charging plates using a cloth, i used my own T-Shirt.
6.Put battery in and REBOOT.
7.Clean the charging pin of the charger using the safety pin/Brush or both.
I have it on for 15mins and no problems. Removed and put the charger again and again, still no problem. After waiting for 1 week, i am able to charge it using its charger! Now lets see whether it lasts......:-/
Edit(3): So, my phone acted up again last night, with driving mode and car dock. I used the pin solution, No problem till now. its Peacefully charging. Bah! it really is annoying
Edit(4): Now, its been 24 hours since my last solution, and phone hasnt acted strange. I guess after another 12 hours ill rule out the permanent solution. Which i used.

same here
Well.. I'm having similar issue. Battery drain and random driving mode/voice search sometimes. It all started after last OTA update and rooting without changing a ROM to custom. I've clean out USB port and no result. Maybe it's time to scan system with AV or unroot device...

I had the same issues 2 weeks after i bought my galaxy s2. Took it to Samsung customer care and they replaced the micro usb port. Haven't had a single issue since.
PS: Try to dry out the port and the phone if it is a water logging issue. I used a hair drier to do that. Luckily the tab that indicates water damage hadn't changed colour.

Had same issue with my Samsung Galaxy Note - randomly going in and out of driving mode, used a dry, soft toothbrush to clean out the USB Charging port, so far so good.
Make sure to flick the bristles of the toothbrush back and forth with your thumb first as you might see a lot of dust fly off of it.
Don't use anything hard like a pin or needle as you might scratch the contacts.

It's just a software problem, the reasons might be:-
1) you might have opened and closed some huge apps randomly and very rudely..
2) You are low on space on the internal MMC Card
3) Your phone might be performing the restarting apps re scheduler
Solutions:-
1)Factory Data reset will not help as the cache section might be corrupt.. neither the android 3e will help...
2) a)Use odin and download the Latest firmware package from Sammobile's Website.
b) for tutorial on flashing, go http://forum.xda-developers.com/showthread.php?t=2488942.
c) Do not touch the phone after processes and restart was observed...
d) Again get into download mode and re flash the same Firmware again...
e) Restart the phone holding the HOME key, (it won't do anything by itself)
f) it will surely fix your Phone
3) Message me if any problem persists...

The new infuse drives me mad

Okay, to make it short, I've brought home a Samsung Infuse for testing. It's not even a day yet and it's showing one hell of a problem already. Firstly, I can't install the right drivers for it. I've used Kies and tried downloading every drivers I can find but no, the phone won't even connect as mass storage. I tried going into download mode by holding the volume keys and insert the usb cable but it only gets in download mode once every 20 tries or so, the other times it just boots right into the OS. In the rare cases of successful download mode, Odin won't recognize the phone. I used SGH-i997-UCKJ4-One-Click and finally it said the phone is connected, but intructed me to install the right drivers. So I did exactly as it said but the whole process of reinstalling drivers just repeats. I put the cm7 and mosaic ROMs in the phone using wifi and flashed them, here I met another problem, the phone keeps getting into car mode. I disabled it, and the phone changed orientation although I tried disabling it back and forth. I'm raging at it here, does anybody know about these problems or should I throw the infuse at the seller's face?

sounds like an issue with the usb port not the drivers.
try cleaning it, or you may need to send it to samsung for repair. if you dont want to do that then i'd make you an offer on it, but you might be insulted at what id pay for a "broken" device.

Something I ran in to as well, I ended up using the ports on the back of my PC.
Something else too ... I ended up using a Blackberry USB cable.
Hope this helps

Yea not an issue with infuse but the USB port. My laptop connects to it if I use the secondary or tertiary USB ports.

people read the whole post. his issue is not limited to computer connectivity. the phone goes into car mode on its own. car mode is triggered by a simple resistor in the car dock. different resistor values will put the phone in the different dock modes, Adam outler had a bunch on information on USB standards when he made his own captivate car mount. what is going on is most likely that a piece of semi conducive material is trapped in USB port on the phone or the port is otherwise damaged on the phone. there could also be some physical issue or calibration issue with the chip that controls the USB. I have seen similar issues on my own phone and seen atleast one post with issues identical to mine.
the seller sold it for a reason.

USB not mounting and computer does not detect

Ok I have drivers installed and USB debugging is off all the normal stuff and the phone beeps but storage does not show so I can mount the computer does not detect??

Go into settings wireless and networks USB utilities and toggle the setting in there.

Sounds like PC to me, happens reboot PC and phone if it does not help I would suggest plugging it into another computer. If it works then try your computer again. This happened to me before with an external hard drive. Hope you get it worked out.

This also happened to me, it was working properly before but it just stopped. It seems that the phone always detects that there is a USB connected even if there was none, evidence is it is always in the charging state when I check the battery status. I think this is a hardware problem. I'm still looking for a solution for this.

USB issues like this will never make sense to me. It's working fine and then not, back and forth. I too am looking for a resolution.

I've never UNCHECKED USB Debugging.... during Odin connections or transferring files between phone and computer. As soon as I plug USB into phone, the USB symbol appears in notification bar and then I press notification to transfer files between computer and phone. My SR internal and external storage are recognized as drive letters on the PC. Try leaving USB Debugging checked and see if that works for you.

i highly believe this is a hardware problem because mine started when the phone overheat and turned itself off. I already tried resetting to factory setting but still the problem persisted.

good point there have been instances where I have had to switch ports to get it to work.

I remember also having the same problem with a USB cable I used with my captivate. This cable worked well with the captivate but when I plugged my Sky, I had the same problem as you. It took me a while to figure it out and change the cable.
Hope it help

Thank you.

Hey guys. I recently came across the same problem as the OP.
My phone will not detect that it is connected to a computer, and the computer will say that the device is not detected/has malfunctioned.
I have tried a factory reset, I have tried USB debugging, checking and unchecking, I have tried going into USB Storage and hitting the connect to PC button.
The phone does not connect using any of the 6 USB ports. It does not connect to my home or work computer. I have used two different cables, the stock and a third party one. (I have always used stock, never any third party until now to resolve this issue.)
This problem also came out of the blue, no changes were made. The phone is stock no rooting or flashing. Although that was the plan, but now it seems pointless.
Judging from the responses on many websites, I would have to say it's a software issue that can't be resolved. Or maybe a hardware issue. Either way I'm sending it into Rogers (Canadian carrier it originated from) tomorrow if I can't fix it by tonight.
I would love help from the outside public, but please respond with suggestions that are more intricate than to hit the connect to PC button, as I have exhausted all of those options already.
If this is a random occurrence, (and it seems like a common problem from all the results I get when searching for answers) then this phone model really needs to have a fix or something down the road soon, because this is ridiculous.
EDIT: Also tried reboot of the PC. It's Windows 7 64-bit so shouldn't need drivers either, and it was working fine last week.

If u did all that, u did ur due diligence in troubleshooting the problem. I almost guarantee ur mini-usb is dead, or maybe damaged so that it still allows charge but won't connect to computer. Send it in to Rogers, they should give u a temp phone in the mean time becuz its under warrantt

Yeah I figured something hardware related decided to crap out on me.
Is there a specific cause for this to happen? I plan on rooting and flashing different roms when I get the phone back, and don't want to have this happen again out of warranty, or else I'm screwed.
I try to take good care of my phone, so it's weird that this happened. If it is a common problem, then I guess I'd have to be careful to not do anything on my phone that's not reversible.

Replacing the usb port on some devices arent solving the issue.
For example, i have a usb bricked GT-N7000 and technician said that usb port is working on another device but there is something blocking usb mounting in the emmc. I dont have a bricked emmc, but the thing is i have been searching all over to find a fix for this thing more than a year now.

Stock Charge problems

Starting yesterday my phone boots up in Car Mode- every time. Rebooted at least 10 times, battery pull etc. Won't stop. I've never seen car mode before. Same if plugged in or not. Also at the same time the screen now rotates when auto-rotation is turned off. Checked settings in Go Launcher etc. Can't figure it out! I'm up for early upgrade and can go get a Note 2 today but am hoping this thing will make it until the S4 is out! Phone is stock- the only reason i ask questions here is that i know you guys know your stuff and i might get a fix!

And speakerphone is on by default now when taking a call.

could be the car mode app - some setting in it is telling it to launch at startup. I would try to either clear defaults for that app or download another app that enables car mode (like vlingo), and see if you can force it to ask you upon startup.
regarding the rotation - you might need to uninstall and re-install GO.

My Charge did that once. It was a bad USB port. It sucked because it also kept the USB port from being used for anything other than charging...it would not recognize it as USB.

Bad usb port. I took a tiny screwdriver and bent the the little metal plug up inside the phone. Now it functions right. Can upgrade now but patiently waiting for S4.
