Hi northerncrown, Unfortunately this seems to be a widespread issue with the Zenfone 6. My Zenfone 6 actually died a couple of months ago https://zentalk.asus.com/en/discussion/55831/phone-is-starting-to-die and I have seen others post about the same exact failure like the one I ran into from other countries as well. I'm really disappointed in Asus for making a faulty product without acknowledging it. I'm curious, how big of an issue is it for Zenfone 6 owners in Japan? Do you know many Zenfone 6 owners with the same issue? Would love to hear about it.
Many Zenfone6 users in Japan posted sudden death approx. 2 years use. I visited several local repair shops and heard that all of these repair shop owners experienced this issue Inquiry. Unfortunately, they did not have good solution for permanent measurement. Similar reports appear in google search suggestion even just typing "zenfone 6". I also really like its performance. If the phone doesn't fail again after repair by ASUS genuine service factory, it's worth to pay. But it is unclear as we have no clear explanation.
