Hi,
when getting used to my new BV9500pro one main issue I am experiencing is, that any other than the standard OEM headphones do not seem to fit or rather stay in the headphone jack. They litterally are popping out or can be removed with no force - the last soft click of the OEMs is missing, which seems to be holding them into place. The plug itself does not seem to be substantially longer like on other previous Blackview phones, it is surely not 17mm, but it might approx. 0.5 mm longer depending what you take as reference for measuring. All in all I would say it is 15 mm long instead of 14.5 mm. Is there any adapter or other fix to this problem?
Regards
