Backstory The now-infamous Galaxy Note7 was recalled by Samsung twice (and finally completely canceled) for its exploding batteries. After Samsung's long investigation into the cause of the explosions, they determined that the only issue both the original and post-recall models of the Note7 were manufacturing issues with the batteries themselves, as reported by The Verge.
Question Given that the only things making the Note7s explosive is their batteries, is it reasonably safe to pick up an explosive Note7 and immediately replace its battery with one not made by Samsung? And is there a Note7 replacement battery available that's not one of the Samsung originals that will explode? If this is possible, it might be possible to get an amazing (and safe) phone quite cheaply.
Note: I have no plans to do any such thing even if it is technically safe and I highly discourage others from trying to buy/use a Note 7.
