So I have several portable chargers they used to fast charge my samsung devices one day this has just stopped and they only cable charge. I have an s6 and an s8 and have the exact same issue with both of them. They will only cable charge from the portable chargers but they used to fast charge. I have tried different cables and today I went into a phone store and the guy there tried all of his portable chargers and cables he had for sale and on both phones the same issue happened they would only cable charge even though all of the chargers i used said they fast charge on them. He tried the portables on his own samsung and it wouldn't fast charge either. Have samsung done some software update that stops fast charging from portable chargers? Like I have tried 8 different ones on 3 different phones and none of them will fast charge. It seems like something has been changed where they used to fast charge but now they don't anymore. Anyone know how to fix this? Or did Samsung mess something up on the software updates?
