In remaining devices Galaxy A30s is more costly , heavior and featurefull than other device ,so I think A30s should be get update firstly than other😌😌😌😌
We know that it take time to develop one ui but Samsung has improved in updating its devices than before so a hope to update the remaining devices faster is still there for example A30s can get the one ui 3.0 in April then later it get 3.1
