The charger, which was with my tablet case, was "Made in Vietnam". During my Tablet invites, I can use it properly. The 3 new chargers are "Made in China". While I invite my tablet so, the touch screen is hard to use. My finger pressure / pulling is not recognized, for operations are recognized, I'm not at all. The Samsung tablet is therefore hardly usable during charging.
It's not the tablet, because with the same charger from Vietnam it works, yes. And if I invite other phones with the Samsung chargers from China, these spiders like that.
I'm disappointed!
