Several android devices complain when they are not plugged into their manufacturer-designated chargers. One samsung tablet I own won't even charge if its not on its own brand charger.

Is there some code between the device and charger, or is it just the voltage / amperage gauges?

  • I know that on some samsung devices the charging pins are longer. So the device can tell if the original charger or another generic charger with shorter pins has been added. – 1990clb May 7 '14 at 14:18
  • Hum, Samsung is going the 90's Microsoft rabbit hole all the way (and we all know how it ends) but some Motorola devices also b** about the chargers too. So its not a Samsung specific question (hence no Samsung tags). – Mindwin May 7 '14 at 14:21
  • Yes there are parity strands in some cables that allows the device to identify if its own cable or not. I don't understand why manufacturers have to be like that but they are. I know devices that use the same exact cable (voltage and plug type) but they can't be interchanged, its ridiculous. – GµårÐïåñ May 7 '14 at 15:44
