I had a short experience with the Asus Zenfone 6. After 10 days of use, the display has failed. I asked for the replacement from Asus but in the absence of availability in the warehouse, they gave me back the money (which still have to enter on paper). Summary: 10 days of use, 18 days of waiting, still unfinished ... a phone that seemed interesting to me was a nightmare. I come from a Zenfone 3, but after this experience, I change the brand.
