Hi guys, I have a samsung galaxy s vibrant from bell, and lately I have not been able to use my phone while charging. My phone lags and does not respond when i try to unlock the phone to go to the main screen.If I want to make phone calls and while charging the phone i would have to dial the number first then plug in my charger. But once its plugged in the touch screen does not respond at all. please hellp!! I;ve tried deleting apps to see if i have downloaded anything that may have caused it but it hasnt worked. I tried soft reseting, taking the battery out. So far nothing has worked. Any one else with the same problem?
Same Problem
I have the same problem with my Samsung Vibrant....I don't see the same problem with my usb to wall-outlet charger....however, the touch screen freezes up when I use a third party charger. Please help.
I have noticed this too. Anyone smart why this happens? Its not just galaxy s phones btw.
Noticed the same problem. While charging, the Touch screen doesn't work. Especially while using Swype, the Line is jagged.
....and automatic PIN
I have exactly the same problem (i9000, Sweden, 2.1 update 1). Unfortunately I did not think of the charger so I kept removing the battery
When connected to the charger when starting the phone and I have many pictures or video files on my memory card, the text "media scanning" and "media scanning finished" (or something like that) keeps repeating in the system info. When the PIN code windows appears, numbers are being highlighted quite randomly. Sometimes the "ok" button is indicated as well, so sometimes I have been forced to use my PUK code because all 3 PIN code tries had been done with noone actually touching the phone
Again, without the charger (and/or many media files) it works.
Maybe froyo could help
I am on 2.2 Froyo and it still happens for me.
Same problem with Froyo JPO!!
Problem with Selective devices or all the devices are having the same issue?
We need more confirmations.
thats because third party chargers have different voltage and charge that will affect your capacitive touchscreen. HTC chargers are recommended, since they are also touch screen based phones.
just searched for this problem and solved it immedieatly thanks to hoopjunkie's comments
i've 2 chargers,
the one came with the phone has output 5.00V 0.7A
one claiming to be samsung has output 4.75V 0.4A
I had never used the phone while in charge so never experienced this issue until 5mins ago
for some reason i was using the "fake" one since.
lesson learned check the voltage values, which i normally do, but trusting too much to the sellers got me.
ow and for the record I'm on froyo 2.2 i9000xxjpc
I am using the Stock charger. Same problem even with the USB Charging.
i wonder if theres a solution to this issue?
i am really getting tired of this problem -- i am using a nokia n97 charger.
i want to be able to download stuff from the market while the device is plugged in.

Hi, I got the same problem: no touchscreen when connected to USB of my laptop. I already noticed my phone acted weird next to my laptop. Once I ejected my cd-player the touchscreen worked again! So the electronics in the cd-player interfered with the touchscreen.
I've got a Rogers Captivate running 2.2 and I am having this same problem... it only seems to happen since the upgrade. This is using the stock charger and USB. Are there any possible solutions to this?
Same happens for my Samsung Galaxy S while charging from the stock wall charger. But the touchscreen works perfectly fine while charging from a PC's USB port using stock microUSB cable.
I think the problem lies with the charging current. The electrical field generated around the charger's wire due to a 500 mA (5 V) charging current supplied by PC's USB port seems to be doing no harm, while the 700 mA (5 V) charging current of the stock wall charger seems to be generating an electrical field high enough to confuse the capacitive sensors of the touchscreen. Perhaps the usage of a shielding core -- just like on the stock microUSB cable -- on the stock wall charger would help in negating the ill effects of the electrical field generated by a 700 mA charging current, but I'm not sure.
Anyway, my current workaround for the problem is obviously to charge from a PC's USB port. When a PC is not around or not switched on, I'm using a 5V, 500mA charger which was bundled with my iTech bluetooth headset. Obviously, both these methods have a shortcoming, that is slow charging compared to that of the stock wall charger. In my experience, this is a problem only when I use my phone for Wi-Fi tethering, in which case the battery capacity percentage continues to drop even when connected to a 500 mA charger. The positive side of 500 mA charging is that it gives a slighly better service life for the battery.
Same problem here, send my SGS to samsung and problema solved new display and display circuit its a know issue with some SGS's
I have a powermat in my room that i use for charging my phone up when I go to bed at night. But it seems that I can only charge my phone up by having the phone on. When I turn it off and plug my phone in, it just turns the phone back on. Although this doesnt happen when I plug in my phone into the Samsung usb cable that came with my phone, when its plugged into my computer.
Can anybody explain to me why this is happening? Just a curious thought I had.
I have experienced this with my powermat as well. One thing I noticed is that it wouldn't do it on my wifes phone running continuum 4. Only on mine which was running gingerbread roms. Didn't matter which rom either. Once I upgraded her phone to gingerbread hers starting doing it.
Could this be a gingerbread kernel thing? It does it with every different GB kernel I've used also.
A new day and perhaps a definitive answer to this. Would anybody else happen to know a solution to this? Or why it would be causing this issue?
I haven't noticed mine turning on beyond the charging notification. I've used the stock 2.1 and 2.2 and also the FireFly 3.0 Rom. I did notice a while back on some forums on Android Central that people who were using chargers other than the stock chargers were experiencing different things. If I remember correctly it has something to do with the exact voltages the charger supplies to the phone versus a USB from a computer and so on. Maybe it was the amps. Anyway these minute differences in the voltage tells the phone how to respond to being plugged in. I've got a couple of wall chargers from some long gone Verizon phone (RAZR I think) and my Captivate thinks it's connected to a PC and starts USB Debugging. (I am currently working on some Apps so I have left that option on for now.) The phone charges just fine and the chargers only have current through the 5V and ground pins so it shouldn't be able to do anything to my phone anyway.
Perhaps there is a setting in the ROMs that you are using that tells the phone to be turned on when connected to a PC and your phone is reading your charger as a PC. Just a thought. There might be a setting or something in your USB settings that would let you toggle that or it might just be in the ROM. I hope that gives you a possible line to try and start looking for your answer. Sorry I don't know more about it.
I'm under the impression that when the phone thinks its being charged by USB only draws 500ma which is barely enough to run the phone let alone actually charge it.
When the phone registers as AC charger it draws whatever it wants 1000ma or higher.
So heres the dillema; around half the time I plug into AC the phone thinks its USB and charges slowly, sometimes I need to replug up to 10 times to get AC charging done.
This is using the stock charger with a non stock cable, but a 12v car charger I got with the phone has the same issue.
I don't think its kernel related, and I'm on temaseks latest cm7 kang
Anyone experienced the same issue? Dont know if it happens on stock cm7, haven't had a chance to Test.
Thx

It's a hw problem, mate. You can verify it by flashing stock rom, and see what happens. If it still has the issue, you have to send it back for repair
I haven't yet tested with stock rom, sorry thats next on the cards but I can't think of any way to actually do that, USB data isn't working and I can't use airdroid because there's no wireless here.
So here's the deal..
It started intermittant, didn't take too long to get it to register AC. Today it finally crapped itself, over 50 connections from the LG official charger and ALL recognized as USB
So here's where the cool part comes in.
I live in Australia and I bought it off an eBay seller in Hong Kong, is LG warranty international or must I go through the eBay process?
I'll test a stock ROM as soon as I can, and hopefully delete this post if it all works out but yes anyone with knowledge on any of the things i've brought up would be greatly appreciated, thanks.
Hello,
I got an issue, that i can't solve, and i wanted to know if anybody here got it, and in case there's a solution for that.
whenever i plug my LG2X running CM7 RC2 to my car charger, after few minutes the headset icon appears, and the device "thinks" that a headset was connected to it, therefore I can't hear GPS instructions etc'
when using the home charger, there are no problems
I'm running Cyanogen 7.1
Any ideas or solutions?
Thanks
Guy
I would try changing the brand of the charger if it's not an LG and do tests with other's car chargers. I assume it doesn't happens with the regular charger.
Just a thought. I had a Captivate do the same thing, & it turned out to be crud in the cable end. Try compressed air in the cable end & charging port on your phone. If not, ditch the charger/cable before it fries the phone.
Hope it helps!

Thank you both,
I have tried switching charger. That was actually the first thing i did before posting this.
however, it does not help. The problem is general to car charging.
It is not related to my car, as i had the same issue with other cars, and other chargers.
this seems to be a software problem.
Guy
perhaps an app like https://play.google.com/store/apps/details?id=com.dwalkes.android.toggleheadset2 might help?
One thing's for sure; you're getting stray resistance in the charge port. Id still remove battery & find a non-metallic object to "gently" clean the contacts where the charger plugs in.
I accidentally got crud in my cord, but didn't realize it till the phone started going into download mode using this certain one. It was cool till it fried the phone ...

if warranty = true
then goto return_device
Thanks,
Tried it, didn't work, same problem.
Went to a music festival over the weekend and used a portable charger to charge my phone, this is the last time I remember my phone fully charging. Once it died and I got back home, my phone would occasionally say USB connected and not charge until it said USB disconnected. Now it doesn't say that anymore but it charges ridiculously slow...
-Overnight charging I got 40%
-Left my phone for 3 hours and got 11%
-Use my phone while it's plugging into the charger and the battery still lowers rather than charging.
I've tried putting it in Ultra power saving mode and charging it while it's off but there is no big difference, I'm mad cause this cable is supposed to be charging it super fast.. Writing this post while my phone is plugged in I've already lost 2%
Nothing is wrong with my cord or the plug I am using, it's all the same stuff I have been using before. Could there be a problem with the port or something? Helppp
My phone is also in great condition always had a case, and just got it this past April
*also my phone is rooted so I don't think I can use the warranty

Are you sure? Cords die easily. Can you confirm how many amps the cord and the plug are allowing to be pulled? I've seen different phones pull different amps from different cords and plugs.
You can un-root and get back to a clean phone if you want to take it back.

How can I confirm the amps? And all I know is I've never had a problem with the chord before and I've even tried regular microusb cables that do the same thing

*#0228# this will show ur battery stats. Post that info. Also the is a option to reset your fuel gauge stats but I do believe you need to be fully charged for this.

If you have tried other cables and get the same result, you may have a problem. However I have seen cords got from .44a to over 1.2a from two different phones though.

check the power brick your using, if its the Samsung one that came with the phone it should be like 2 amps if I remember. id suggest using another power brick to test. also if you have a usb 3 super speed port on a pc or laptop sometimes you can use device manager in windows (start menu, right click computer, manage, in the window that opens click device manager, expand the universal serial bus controllers heading, check though any devices that say hub and go to their power tab) to see how many amps something is pulling from a pc usb. the other option is that you might have a defective battery but I don't know for sure. these are just some ideas that may or may not work for you.

Sounds like the portable charger might have been able to adjust amperage or voltage. If that's the case the portable charger could have damaged your battery if it was wrong amp and too high of amps. I have a portable charger that even changes voltage that could ruin a device too if not on 5 volts.

It sounds like it could be a battery problem. More likely, it could be a problem with the software. I would back everything up and flash another ROM or bring it back to full stock.
Option 1:
Install this app https://play.google.com/store/apps/details?id=ccc71.bmw
It will tell you batter voltage and charging current.
Options 2:
Charge with phone powered off.
Thank you everyone for the replies, my phones been getting worse to the point where it sometimes wont charge.
I think what im going to do is flash back to stock and bring it in to samsung or something , but also i heard a rumor that towelroot doesnt void the knox warranty? if this is true i may just bring it in as is...only becuase when i connect my phone my laptop wont read it anymore either, i havent tried if odin will but im assuming it would, i just dont want my phone to end up bricking because of the bad connection
This sounds like an old problem with Samsung phones, including the Galaxy S series. My original Galaxy S did this, my S3 did this, my sister's S3 did this. On those phones it was the charging port that caused the problem. My sister had her port replaced and her phone is working fine again.
Although I don't know for sure if that's your problem, that would be my first guess.

Yeah I'm pretty sure it has to do with the charging port, my battery is fine and so are my cables, and it randomly keeps saying USB connected/disconnected and won't change when it's "connected"
