freestyle4all, Jul 14, 2019 : It's for me - almost - impossible to set my own ringtones on my OnePlus 7 Pro. Tried: Ringtones (mp3 of m4a) in folder Ringtones Ringtones (mp3 of m4a) in folder Audio Ringtones (mp3 of m4a) in folder "whatever" All of these are not visible in the Ringtone area. Succes: Ringtone send to me in a WhatsApp message(?!). No succes: My own ringtones in the same folder. This was no problem at all (with the same ringtones) on my LG G6. Someone?
