Mines the opposite, in regards to face unlock.
Its far better than the s20, as is the fingerprint scanner.
Also impressed with the battery life.
With currently being off, on furlough, I plug my phone into charge when getting into bed on a night. Due to watching tv way longer with not having to set my alarm, for 4.30, it's normally charged before I try and sleep & is therefore unplugged. One day last week it had been 26 hours since charging and it was on 29% when I plugged it in. No way did I ever get anywhere near that with the s20.
As for 100x zoom, I can't say I've ever, or will ever, use it.
Personally I'm loving mine. Not a massive upgrade from last year but it's definitely better all round, imo anyway.
