A subsequent internal investigation run by Samsung confirmed that the Note 7 was done in by two different battery models. Samsung has started to implement an 8-point battery inspection plan for all new handsets. And in an effort to prevent battery issues from rearing their ugly heads again, the refurbished Galaxy Note 7 units will be powered by a 3200mAh battery, a smaller capacity than the 3500mAh juicer that originally powered the fateful phablet.
Some also blamed Samsung for the explosions, complaining that the manufacturer was too ambitious. The Galaxy Note 7 contained an iris scanner, a fingerprint scanner, a 5.7-inch Super AMOLED screen protected by Gorilla Glass 5, and had an Exynos 8890 or a Snapdragon 820 chipset under the hood (depending on where you bought the phone). 4GB of RAM was inside along with 64GB of native storage. The 12MP camera on back came with an f/1.7 aperture and OIS. The selfie snapper in front weighed in at 5MP and Android 6.0 was pre-installed.
Don't expect to see the refurbished Galaxy Note 7 in the U.S. Even though a handful of fans decided not to turn in their unit (which Samsung has practically turned into a conversation piece by disabling most of its functionality) most Americans are moving ahead, looking forward to the Samsung Galaxy Note 8. The Samsung Galaxy Note 7R is apparently going to be limited to Asia and possibly some parts of Europe.
