I experienced an issue last week, but it seems like it is an old issue. I didn't see a resolution.
Galaxy S5, using the original Samsung charger. Batteries charge fine with external charger. I ahve 3 different Samsung brand chargers - none work.
All of a sudden i was getting the "incompatible charger" message.
I did a factory reset, it worked for 1 day then reverted back to the incompatible charger message.
WHAT IS GOING ON???
