I, unfortunately, purchased this dual-SIM card phone last year.
The plan was to have different ringtones on each SIM card, one for business & one for friends.
Nobody told me that this capability disappeared with Android 6.0, for whatever reason.
Now, I'm lookinh for the Android 7.0 upgrade, but my phone model isn't even listed on the list, unless it's included with the standard Z5, which seems reasonable.
Thanks for allowing me to vent over the lack of separate ringtones.
Solved! Solved! Go to Solution.
Had a look at Sony Mobile forums for you, and it seems that the option exists in Android 6.0 but not in the software update provided by Sony.
Your beef seems to be with Sony, and not Rogers (as @Meowmix stated).
