I have my own experience with this phone
I have 5 big reasons to not buy xiaomi mi a2 xiaomi used to give great product at good price but now the price of mi a2 is very high and this is not a budget phone .
( 1) . No headphones jack
( 2) . No longer battery life
( 3) . No sd card slot
( 4) . Face unlock feature is also not available in this phone
Do not buy this phone according to its price there is nothing special in this phone
Thank you
