I'm having a problem with my Samsung A50, I was prompted to update the software on Tuesday just gone. Ever since it wont charge of the mains sockets on the wall only from my USB port on my laptop. It registers the charger is connected, the battery level wont increase though. I have tried everything, original cables, new cables, different combinations of cables and wall plugs(at lest 6 different combos), different wall sockets, cleaned out the ports with compressed air. Changed to charge only from developer options.....EVERYTHING!!! I have an app that tests the quality of chargers and when the same wire is plugged into the wall it registers 0mA so its not going up or down but when the exact same wire is plugged into my laptop I get between 800 and 1000mA and the battery level goes up. This is some seriously frustrating stuff let me tell ya, please help!!!!!
