My Samsung Galaxy S3 died after 8 years. EMMC failure. Just started boot looping while I was asleep. Everything gone. Known issue.
My Samsung Galaxy S8 died at 7 years. Some kind of thermal failure, I was able to recover my data by keeping the phone in the freezer while I copied. Known issue.
My Samsung Galaxy S21? I figure I've got another year or two in it before it, too, dies.
Having beautiful dead phones that have never had a broken screen or a hard drop is pretty depressing.
I am noticing something those devices have in common.
My Galaxy Tab also has dead EMMC. My HTC One M8 still works and even holds a day of charge. Too bad Android doesn't support 32bit ARM anymore.
I bought a used Samsung and it started boot looping almost immediately, all these issues seem very specific to Samsung
