Samsung’s Galaxy Note 7 debacle officially wrapped up yesterday (or at least we hope), with the Korean company announcing that flaws in batteries from two different suppliers were to blame for the device’s explosions. Now, a series of photos showing what appears to be the company’s Note 7 battery investigation facility have popped up on Twitter…

Everyone can use an Echo Dot: Just $50!

They’re not exactly the most high-res photos we’ve ever seen, but they do appear to show rows of hundreds of Galaxy Note 7 devices lined up running what would assumably be processor-intensive testing apps. Appropriately, if you take a look at the first photo below, you’ll see a miniature fire extinguisher just waiting for one of these phones to burst.

After multiple recalls of the flagship smartphone (and months of trying to convince customers to return their phones, which lately has meant drastic measures), Samsung yesterday announced that — after a long investigation — it the batteries from two manufacturers were the cause of Note 7 explosions.

As we noted yesterday, Samsung has now committed to an 8-point battery safety check for all their phones going forward. The tests include durability and visual inspections, a disassembling test, a charge and recharge test, and even an X-ray of every single device before they leave the factory. Samsung also plans to share this testing standard with other OEMs.
