I am finded why cant set ringtones.
I, normaly, use Sim memory, for contacts, and when copy contacts to phone, I can have diferent ringtones.
But now havent option, to save new contact on sim, and phone when sincronisation is off.
When is sincro, on, google take contacts, mix contacts and mail adress, etc.
Dont wanna google together, with my personal things..
On my old Huawei is posibile to have sim memory for contacts and diferent ringtone for sim contacts..
Sim is better for contacts memory, when phone is braked..
