I was with Asus since Zenfone 2. Two weeks ago I retired my Zenfone 5Z. I finally became too tired of the lack of support including timely security updates. The last thing for me was my Zenfone 5Z utilizes 3G when using voice here in the US. ATT notified me when they shut down their 3G systems in February my phone will no longer function voice wise. I've since moved onto OncePlus and won't ever go back to ASUS. Asus made it very easy for me to leave them & they have no one to blame but themselves.
