As a zenfone 6 user , do not buy this phone if you are not ready with the factory reset solution from the mods, i have been following this forum since i bought the zenfone 6. i saw a lot of people having problem with their phone, and all of the solution after you reset or restart your phone is , factory reset it. This is the worst phone i ever use, i am planning to sold it when i got enough money to buy another phone.
