i think if xiaomi use android one or stock android experience then it will attract more users.. MIUI still may have bugs or some people do not like it..

however, someone who will buy Mi flagship definitely is opt for cheaper flagship among android phone without care on the UI and bugs..

I remember when i bought Mi 9 for my gf just priced at RM1999.. if there is 3k for mi 10 then quite a huge price increase.. but with these hardware, i think should be fine.. but all depending on how you think.. majority people around me willing to topup and go for iPhone. while there are few people will to take old flagship.. in market, price drop with big gap is like p30, s10 & etc.

yeah i did use Mi A1 before.. really stock android which i really like it.. but i remember that time chipset is SD625.. sometime may slow a bit for certain situation.. Overall still is a good midrange with good battery life..

Android one really slow updates as far as i know.. MIUI do have fast update, quote example in Mi 9.. get android 10 quite fast.. however, it do have some bugs.. may google search like facebook download manager notification (keep popping out), fingerprint scanner problem..

however, the issue do have better resolve in latest updates.. (Based on my gf Mi 9 experience). cause i need to help her on this kind of thing..

i do hope some battery optimization behind the system dont be so aggressive in MIUI / EMUI (Huawei).. they really killed the apps to achieve longer battery life.. one example that really disturb me a lot is Chromecast (Google Home app).. i cannot control after i turn off the screen cause system really killed it.. i have to reconnect my chromecast again).. my Sony Xperia 1 do not have this kind of issue..
