This is regarding bottom speaker issue on my Zenfone 5Z. A week ago i noticed this problem with my 5z' bottom speaker. Earphone (both wired & bluetooth) working fine but suddenly when i disconnect those earphones from my phone, sound just comes from upper speakers not from bottom speaker.
Now bottom speakers are working as per phone's mood.
