I need to do with the other brands like LG, Samsung... but, there's not happen, the Zalo brand in Vietnam. If, Zalo in Vietnam is better than a LG in Korea, and, Zalo is one of the major brand names in Vietnam. LG did makes mobile phones and, Zalo did also makes instant messaging app for iOS/Android.
Most likely, Zalo is considered one of the "Big Three" brand names alongside next to the LG, and behind Samsung... Zalo is only name for the brand in Vietnam, one of the featured brand names that compete against with an other things like Minecraft. These can be found for the brand name on there.
