Hie there. I have a problem with my Galaxy S8. I was using my phone half way and it shut off by itselfs. I tried turning it on and it doesnt seem to be active. I went to my nearest repair shop and told me that the battery is working fine. What can be the cause of the problem. Thanks Guys!! P.S I tried soft and hard reboot already.
My sister had the same problem where it would just shut off out of nowhere but after she changed her battery it worked just fine.
