How is your head unit working do you have the wifi and bluetooth problems were you have to restart your head unit to get wifi and bluetooth working because I'm thinking about buying the
Eonon GA2171B unit, px5 4gb RAM, 32 Gb interval
This one !
I booted in TWRP and from file manager, deleted /data/system/users/0/fpdata/fptemplate.db and /data/system/users/0/settings_fingerprint.xml and now everything is ok, I can delete and learn new fingerprints.
Thank you very much! I'm a rooted Zenfone owner. :)
