Coming at the heels from the PR disaster from the Note 7 fiasco last year, Samsung is experimenting with selling a refurbished Galaxy Notes 7 with a smaller battery than the original.
They will sell them in emerging markets like India and Vietnam. Time will tell if they will expand this to more markets. Fortunately, there should be virtually no chance of these phones exploding.
If you’re willing to take the risk and live in these areas, they will be selling these devices online.
