iPhone acts odd, crazy, touch screen, random behavior, while charging
This post only addresses iPhone acting up while charging and using the device.
Problem:
I have a cord and wall charger I take with me in my laptop case. It charges the iPhone fine, but... when I attempt to use the iPhone while it charges on this cord the touch sreen responds CRAZY, or RANDOM, like an invisible finger is pressing another area of the screen.
I can not consistantly or hardly OPEN the device by "slide to unlock" .... most of the time it actually ZOOMs in like the 3 Finger touch.
ONLY when I unplug the phone can I "slide to unlock" and have normal use of phone.
Troubleshooting:
We have 5 Apple devices I tried all the Cords with all wall Plugs...
Solution:
Turns out that we some how have a Wall Plug that doesn' appear to be "Designed by Apple in CA"
All the other plugs either have an Apple Logo or state "Designed by Apple in CA"
...This one that doesn't work properly has the same model #'s and voltage written on the face, but says "Power Adapter made in China"
It Charges fine but, must have a grounding issue or something that causes the touch screen to respond Crazy & Odd.
I Marked this one with a sharpie marrker "X", we just use it to Charge as a last resort.
If you have similar issues this could be your best bet....test it yourself with another cord or wall plug.
