Hello from Spain, I've tried different sonometer apps in my Z1 compact,and what I've observed, is that the measurement gives a values that are lower that they should be, in all the apps I've tried.
I have tried previously the same apps in an xperia E, and the meassurementes were quite precise.
¿Does anyone know how to solve this problem?, I imagine that I can calibrate the app, comparing the measurements with a real sonometer, and adjusting the measurements, but I'd need to buy a real sonometer for being able to do that.
