Like many of you, my Zenfone 6 died today. It was really sudden and without warning, it started beeping and vibrating like when Windows freezes, then died. After that, when I turn it on, it stops at the ASUS logo and blacks out, repeatedly. I had been using it for over 2 years, almost 3 years, so I thought maybe my device was OK. But it wasn't. I didn't back up my GoogleAuthenticator recovery code. Seems like it will break after about 2 years, so watch out everyone! Please back up your data asap!
