Crazy screen behaviour with Magnetic Charger attached

Hey all, I've always had this problem when using a magnetic charger on my Z1c (cheap eBay plug adapter that goes on the end of a normal USB cable) where the screen goes crazy flipping landscape/portrait, opening apps, closing apps ... like it's possessed by a ghost!

When I lock the screen it stops (I assume...).

Anyone else got this problem? I am also using a glass screen protector if that makes any difference.

I also heard over a year ago that when using a magnetic charger attachment it somehow has a leaking/residual electrical charge that transmits across the screen causing random activations ... dunno how this could be at all possible though, lack of science. Or it could be the fact I'm using a cheap eBay product with zero safety/quality control....

Cheers.

DISCLAIMER:

• I have already tried unplugging/replugging the USB cable.


• I double checked that USB debugging was on (tried with it off too).


• I made sure that MTP was selected in the drop down.


• I have already restarted the phone itself.


• I have already updated Samsung Kies to the latest version.


• I have already restarted my computer twice.


• I have already searched everywhere I could think of and have found not a single solution.


• I also made sure not to throw my phone as hard as humanly possible at the wall (haha).

"A Device Attached to the System is not Functioning."

I'm wondering if anyone else has ran into the same error message while trying to transfer music (or files) from the Galaxy S4 to the computer? I am currently using Windows 7 (I've also tried on Windows 10 - same issue). I have a SanDisk 32Gb microSD card inserted and I am stock rooted on 5.0.1 OC1 debloated. I never had this problem before until recently. If I can recall correctly, I transferred music to and from my S4 just fine after the update. I haven't changed anything since, yet this issue has come up. Does anyone have any ideas besides the ones I've mentioned above?

Thanks in advance for your support,
