My p20 pro has been working fine with the supplied headphones(wired) for serveral months. All of a sudden audio has stopped playing through them. Instead playing out the in built speaker... I've tried all the popular apps to see if it's a app problem- This isn't the case. I've reset the phone countless times, tried holding down the up button. On my holidays for another week and I can't relax and listen to anything though my headphones, or for that matter back up the device... I've cleaned the jack port (was clean anyway) now I'm at a loss. Please someone from Huawei get back to me... I've seen several threads online and tried all the fixes.
Any advice would be appreciated,
