    Hello everyone,

    I bought a Wiko Cellphone on Lollipop 5.0.2, but the earphone's volume is veeeeeery low.
    I tried to install some apps, but it didn't change anything, so I just want to enter in the engineer mode to change amplify the audio configuration but it seems impossible.

    I tried the *#*#3646633#*#* but it didn't work, and the mobile uncle App doesn't let me change de audio configuration ...

    Do you have any tips to do it?
    Thanks a lot !!!!
    Damien
