I had replaced the battery of my Galaxy S8 G950FD from service center yesterday, even after replacement the battery is draining drastically and these are the other issues I'm facing.

I'm facing this error on my stock S8 (screenshot attached).I've tried cleaning the cache, data, nothing worked. Please help me.

I've recently replaced the screen of my s8 since then my iris scanner is not working. Whenever I try to register my iris it shows, "your irises weren't registered" and also the red ir light doesn't come up, it only shows my eyes through the front cam...

Edge lighting in the new Samsung music is removed or only mine isn't working?

I've updated my S8 to Pie Beta, I saw a point stating that Dex mode with suitable HDMI without dock. Can anyone help me to find which hdmi cables will work?
