Why on flight mode s9 plus battery drain s like a hell from 15% to 6%.. it drained... bt this doesnt happened for last 1 yr bt for the past 2 days its happening... 

I want to know whether the front camera has gone down after the june update from 8 to 5.2 mp... and the pics taken looks like the selfie taken in vivo camera... how to make the camera to have better look just say me...

Why after october soft ware update charge is draining fastly why it is sucking fastly....
