I'm having the same issue before I even updated my phone. It tells me to use the original charging cord that comes with my phone but thats all I use. Also, sometimes my phone glitches and randomly restarts while I'm using it.
Thanks for that info @userBAVWItLfXz Since this forum was largely designed for US based devices and their owners, I'm afraid I have limited information on international devices. I can do basic troubleshooting but I feel as though your best bet for direct assistance would be to reach out to the Samsung Support in your region.
