Asian women somehow like huge phones for some reason.. I've seem some that were literally small tablets (think 7-8" without folding) and they were always carried by Asian women when I saw them. Maybe this is coincidence. But I've never actually seen these phone models on the market in Europe so I don't think so.
Personally I don't like phones too small, for me the Samsung S-series (5.8" with bezels e.g. S8, 6.2" without bezels e.g. S21) is perfect for me. I have a OnePlus 8 now which is S8+ sized and that's too big for sure. It's not even the one-handed use, it's just clamping it in my hand, it's just too wide for comfort. Especially with a case on it.
