"Natural lifecycle", my a** ! I have a Pixel 1 that worked fine for about two years, then it was replaced because its battery would no longer last for more than a couple hours, but otherwise was fully functional. It sat in a drawer for about a year, until today, when I wanted to use it in a project. I plugged it in to charge it up, and turned it on after a few minutes. It froze during the boot animation and turned off after about a minute, and would no longer turn on, even after I left it to charge for several hours. When I connected it to my PC, it shows up as "QUSB_BULK" in device manager.So, while more than 3 years have passed since it was first turned on, it wasn't actually USED for nearly that long, so no way did any memory component reach the end of its natural lifecycle - like I said, it was fully functional when I stopped using it! More likely some built-in "lifecycle timer" has expired, and it just decided it's time to brick itself so you buy a new one! I mean, I still have a Samsung Galaxy S4 that's about five years older than this thing, and it still works well! (apart from the battery, of course)
Screw you, Google! This was the first and last piece of hardware I ever buy from you! Also, it's time to find some other email / cloud service provider as well!
