Had a bit of a struggle taking photos with my new Smart V8.... as I rotated from profile to landscape in composing picture I wanted the image got progressively darker until screen showed nothing at all.

Much time wasted, and frustration levels building..

Already making plans to take it in to a tech tomorrow I was thinking that this was the same behaviour as rotating to pieces of polarised glass etc.

So, took off my 'shades.. and problem went away. Only with sunglasses on does it present.

Is the display on my phone polarised? - perhaps this is something everyone knows, and I was just showing my ignorance

I have had it before on a refurbed iPhone where the screen had been replaced with a non-Apple screen.

Drove me banana's.

Which, are hard to drive to be fair as they don't have a steering wheel or pedals...

yes, an LCD without a polariser will show only a white screen - I would suggest that it's simply just a lower quality polariser on the LCD being an low end device - the original Apple and Samsung panels have good quality polarisers which play nicely with polarised sunglasses.

Replacement screens generally have replacement polarisers in varying quality.

I'd suggest that if it's a major issue you might want to look at another device.

Plenty of screen protectors seem to be polarised

Had a similar problem recently with my camera. I'm not a fan of polarised glasses for this reason. I have custom made magnetic clip ons and won a second pair in a lucky draw. I'd specified non polarised for the original set, the second came polarised much to my disgust. I keep the non polarised for when I fly and use the polarised ones as a second set.

My wife's car has after market window tints on the side and rear windows. When I drive it and wear the polarised lenses I see some weird colours through the side and rear windows.

You can try a tampered glass screen protector. It can improve viewing angles or make things worse with rainbow effect at any angle.

Do you mean tempered glass or tampered glass?

Ultimately your polarised sunglasses are the issue. I'm personally not a fan of poliarised glasses now and just get regular lenses because there are far too many issues with things like car screens and so on that cause issues these days as well.

Interesting, As I don't have many issues with my polarized sunglasses. I only get dimming on my phone screen if I rotate it half way between portrait and landscape. And even then, only 2 out of the 4 possible rotation options will it dim. Never had any interactions with car windscreens.

Only weird interactions I have had was a set of automatic glass doors on a shop. And some advertising screens like the ones on the Mc Donalds drive thru. Most of the time, not being able to see such screens is a feature. As it is like an add blocking system.

And my sunglasses are only cheap ones from Farmers. As I can't justify buying expensive ones.
