i have upgraded my phone with new firmware 6.0.1 baseband version G9200ZHU2DQB1 with android security patch level Feb 1,2017. after this update that was downloaded automatic in my phone. Fast charging stopped working inspite it is selected from battery option. and also connected phone to computer or external drive by USB is not working. I keep my phone whole night charge but upto morning its only 77%. It doesn't come to 100% completely. i sent to Samsung shop they said its a software problem but as USB is not recognising we can't do anything u wait for automatic update. pls help.
