Hi Guys 

Does anyone know if a phone under warranty will or can be fixed by any blackview agent?
Say I bought a Blackview device in Hong Kong and traveled to SA and it broke there. Can I send it to the Local Blackview distributor in country to fix? 

Will the device be repaired under warranty or would I have to send it to HKG again. 

Yes, as far as it is one of them: http://www.blackview.hk/global-agents/

You'll have to contact them directly.
