Android virtual input, keyboard goes randomly insane

[Jeff_50]

This is caused by typing with the device plugged in to a 3rd party charger. Unplug and all will be well.

HI Jeff_50,

this also happens when 2 keyboards are both active at the same time so you need to choose only one keyboard as the default keyboard.

Thanks for the tip, I'll watch for it. What I'm seeing is definitely the charger. Not just the keyboard, but the whole touchscreen gets erratic. Inadequate filtering on the third party charger is likely the cause.
