not having hardware defects that randomly kill the phone? my phone has a hardware bug that if triggered means it becomes a brick. Something to do with the PMIC, and has happened to developers and users alike. I'm lucky to not have had that issue, but if I do, I'm pretty fucked. Not to mention that a lot of custom rom devs complained about the quality of the blobs for the phone, not to mention that up until the rom I'm using now, Android was pretty buggy since 12 til 14.
