Can someone with Pocophone help me try if it's able to dual app and split screen pokemon go? This decides whether I buy the phone. Thanks.

Is it the brightness or the polarisation layer? SOME (some not all) screens have a linearly polarised layer above the screen (supposedly to cut glare), so if you're using polarised sunglasses, you might not be able to see the screen clearly either in portrait or landscape (it should be clear in one of the two orientations though).

Why? When you put two linearly polarised optical elements on top of each other, if they're put in a way that the polarisation aligns, it turns into a darkened/opaque layer (for folks who are into photography that's why you can use 2 linear polarisers as a variable ND).

Why some screens have this issue and some don't I'm not so sure though.

Anyone here having GPS iisue with the pocophone? My gf bought 1 the phone kept having issue with GPS when using waze. Keep having to reboot the phone for the GPS to work properly. Any solution or is it a known problem???

Which telco you're on ?
I'm on umobile and have high rate of GPS not lock in Waze. Just now back from MidValley, both Waze and GMap cant navigate, I had to follow old klang road to bukit jalil, coz I know how to get home from mrr2 there. Keep restart Waze also same.

Gonna port to tunetalk soon, will test and feedback, if it's umobile problem or poco f1 problem
