I don't look for a $500 phone anymore. As I said, I am currently using a S21 Plus that I've got for $999 with a pair of new Samsung Bud2.
But when I was using the Oppo, I was making a lot of video call while doing a lot of stuff in my phone (Like everyone else during COVID) so I need a good phone that can multi-task with very memory intense operation, which would be set back because I remember My Oppo phone only have 3 or 4 Gig ram, that is not enough to do what I want, and then I needed a good camera to shoot video (was doing some YT video for some Military Channel back then) That's why I think my A74 is not up to the task, but to be fair, my friend recommended Oppo One but it was quite expensive (i think it was around $800) and I simply don't want to drop that amount for a Chinese phone, so I got the A74 instead.
We don't have Xiaomi in Australia. They do in Hong Kong and some of my relative is using them and they have good rep, Vivo and Realme is straight up shit here (They don't have good review here in Australia) and I have never heard of Poco.
