Yes! Offline market will get more commission for selling oppo, vivo, realme, iQOO. If you don't need to go with Vivo then iQOO is having same UI. but Realme and OPPO is so far go with some setting to enable, You will all good to go. Unfortunately, The OPPO and OnePlus having price higher than Vivo and iQOO.
