Hope you have it backed up, because they die sooner or later. For me it was sooner, for my friend it was later. Some soldering problem if I recall things right. A bootloop is the first (and sometimes the last sign).
Tangential to your point, but is there anything useful that isn't backed up more or less by default in the standard Android workflow? I get that the privacy-concerned wouldn't use eg Google Photos, but they also likely heavily overlap with the set of people savvy enough to set up backup solutions for important data.
