With Android, does a factory reset truly reset the device to the same as it was when it left the factory (unlike an iPhone)?
It is the same as an iPhone I believe. A &quot;factory reset&quot; removes all information in the data and user partition, but leaves everything in the system and associated partitions as is. That means if you got an upgrade or update that changed anything in the system partition, it would remain after a &quot;factory reset&quot;.
The reality is that a &quot;factory reset&quot; is kind of a misnomer in this case, it's more of a &quot;user reset&quot; than anything else if we were being more accurate.
