I'm having problems charging my Samsung Tab 2 device. It is reporting as charging after I unplug the cable, and when charging, it is drawing a small current from the charger. I've measured and it gets stuck at 500mA.
When I use the fix of "pressing all the keys during 10 seconds" that is supposed to reset the charging circuitry, the charging process becomes ok, I believe, and it then draws over 1 Amp but, if I unplug/plug again, the situation repeats, and it then begins just drawing a fixed 500mA value.
Basically, when I disconnect the charging cable, somehow, the device becomes erratic.
