I have meizu pro 6 from  dec 2016 , from around 5 months I have a problem. I cant listen music or anything in headphones. The volume in headphone is only around 10% and there is scrathes! like radio bad sound. I thought this is from hardware problem but no water was inside the jack +  i cleaned it very good. Headphones are recognised. I  tried to change flyme so i tried around 4 firmware from flyme 5 to 6 (stable/beta) all G version. In bluetooth headphones all fine. I tried a lot of headphones. Sometimes sound are coming to normal for 1-2 minutes (volume and sound is very good) and after some moments is becoming very badly. When I try to push or to move jack nothing happens so I dont think this is hardware problem or maybe jack itself is broking?
now the firmware is 6.7.4.28G . I want to try and A version of firmware today.
HELP please !
