While I was recording in slo-mo mode at night, is it normal for the screen to be flickering? after i record and play it also flickers but say in the sun it records just fine though? I'm not sure why too and I'm pretty sure it happen both on my S8+ and Note 8 (exynos)

Flickering...or are you seeing Noise? I see Noise...no Flickering. Use the flash and Noise is gone.

Was there any lights on nearby? Street lights or ones in house might cause flickering when recording video. Your eyes can't notice the flickering but camera can.

This could be one explanation

is there a site where I can upload a few seconds of the flickering somewhere?

Scenario is this I am in my room, it was night, so I switch on my lights (fluorescent light) when I point the camera to my monitor there wasn't flickering as soon as I point it away it starts, however, it doesn't happen during the day no matter where I point at.

Were you near a ceiling fan?
LOL, of cause not.

anything over 60/50fps will cause flickering when shooting incandescent/fluorecent source of light . power grid is on 60 or 50 hertz depending of the region of the world you are in.

Your camera is basically capturing the inbetween state of the power current. At 60 hertz means the negative and positive state switches 60 times a second between left prong and right prong on your wall outlet hence the term AC( alternative current) versus DC.
(some camera softwares try to compensate by dropping frames to not match frames that are inbetween power states)
