@GrumpyMom Almost all the lights in the house are LED. I've tried the video on all resolutions and the result is the same in my room. Strangely, in one of the rooms with LED lights (slightly different type to the rest), there's no flicker.
Tried video on all resolutions using the Note 8 and not even a hint of flicker.
I admit, I'm a fussy person but I don't go looking for probelms. This is just far too severe to ignore and hope an update fixes it. I've read all about screen burn, blue tint (which I can see at some angles but am fine with), colour problems but none of that has been a probelm.
I'm tempted to purchase another now to see if it's maybe a hit or miss thing. I'm going away in 4 weeks, so need to know I have a fully working phone with me. It really is a great phone.
