UK, since upgrading to OneUI2 (android 10) on my S10+ before christmas, then upgrading to S20 Ultra, I'm having loads of drops in wifi.
My friend's S9 running OneUI2 is having same issues.
Tried splitting the bands on the router, no help.
Tried Using Device MAC instead of random, no help.
Apps occasionally saying no network.
Can't just be me?
No issues on Android Pie
