I have seen multiple (quality) SSDs with unrecoverable read errors after a few years. All of them had plenty of spare area left. Maybe some kind of retention issue?
How does that apply to android?
The UFS storage inside an Android smartphone is basically an SSD. Both use flash memory, so it's reasonable to expect that they have similar failure modes. But I'm not sure if you could diagnose such a failure on Android.
