Never had any issues with any Zenfone. I had Zenfone 2 (5 years and it's still working, but I'm not the owner anymore), Zenfone 3 (3 years and it's still working without issues, my cousin is using it now), Zenfone 5z which I used for 1 year and a bit and again 0 issues...and now I'm using Zenfone 6 since 2 months and no issues yet.
Instead of being childish and whining on forums, you might try to contact support or go to a service center to fix your phone issues. Every phone can have issues, it's not like if you switch to Samsung or whatever other company there won't be a chance for the phone you buy to have issues. Remember Galaxy Note 7? At least your Asus phone doesn't explode and at least Asus doesn't make phones slower over time like Apple and Samsung do.
