Please update software optimisation n battery life.
Also provide inbuilt applock feature in next update for samsung m30...as we can't trust on third party software like applock..its too dangerous to use...
please also add icon feature to turn off display..so that no need to press power button to turn off display..and also improve picture quality...details after taking pics from m30 is not so good...please provide in nxt update ASAP.
