hello , today received my S9 , after power on , set language , then asked me "european union" and "not european union" , i chose "not european union" .

now ( my brother set "european union" ) difference is that at same vol es. 34/40 , my S9 is more strong .

can my brother re-choose this parameter ?

changing fw , cannot change it .

thanks
