[Q] Problem when using phone while connect to USB

when i connect my phone to USB, i can't seem to use my phone at all... it's very slow and lag, ... if i install the OCLF, does it help? thanks
I had this problem when I used a cheap wall charger. I think it had to do with incorrect voltage or something. When I use the included cable and wall plug, everything works fine. With thaw $2 chargers, the touchscreen wouldn't register or was about 2 inches off or the buttons wouldn't work at all.
Not all chargers are made the same I suppose.

[Q] Touchscreen problems when connected to computer

Hi there, so when I connect my cell phone to the computer via the USB cable, the touchscreen on my phone acts weird and sometimes I cant even tap anything, does anyone have the same problem?
I also have this problem and would like to know what is causing this.
Are you using original cable?
cable + charger related.
i had same issue with my last htc phone as it acts weird on non-genuine charger, now same chrger do same weird stuff on my S2 but. and the cable if used alone via computer also doesnt work properly. so i threw them few days back.
its a voltage problem, so never use local cable or charger, always use original that came with phone

[Q] PC connect/disconnect

i have a fairly new Galaxy S4, but every time i connect my phone to my computer, if i move the phone/cable a fraction of an inch it will disconnect from the computer and immediately reconnect multiple times until im done moving anything. It doesnt seem to matter the cable or the usb port on my computer.
any ideas?
Bunk charging port. That's what my s3 started doing and eventually it wouldn't recognize or charge. I'm sorry.

[Q] Charging issue

Hi All,
I am facing issues while charging my phone from the wall point. It works alright when plugged in into Laptop.
However, when I replaced the USB cable with my old HTC phone's, the charging works fine even from the wall point.
I have a couple of queries:
1. If the issue is with the cable then how the phone is getting charged via Laptop
2. If I am using a different cable, does it mean harm to the phone? I understand that charge is controlled via adapter, but still...
It's well known that Samsung cables are a piece if $&@/!
If your old htc cable works then go with it. I use an old htc one myself. Don't worry, it's just a cable.

[Q] Strange charging

Hello,
My SGS3 was working fine for all these days, but from last week my phone is not getting charger via power adapter but when i connect my S3 to USB its starts charging.
Its strange, when my S3 is connected to power adapter it shows that is charging but literally its not eventhough i left my S3 on power adapter for an hour its on same point(%) when plugged in.
I dont see this issue when connected to my laptop via USB cable.
do anyone face this kind of issue? or what could be wrong?

Try changing your USB cable... I have changed 2usb cables since I bought my s3 due to same issues that you are having.. If it is in warranty customer care will replace it for you.. if not then just try with another USB cable before purchasing a new one..

Yes... I tried different USB cables but facing same issue, not charging when plugged in power adapter and charging when plugged in USB
I think it is probably the USB cable I had same issue but I am now using a black berry cable with the Samsung charger and it's charges so faast
