Samsung has released the results of the Galaxy Note7 battery investigation via a press conference held in South Korea.
The results show that both batteries, the Samsung SDI used in the initial batch and the Amperex used in the second batch suffered from manufacturing defects.
In Battery A (Samsung SDI) the problem was that the negative electrode was deflected in the upper-right corner of the battery, as well as the negative electrode tip incorrectly located in the curve instead of the planar area.
Battery B (Amperex) had high welding burrs on the positive electrode which resulted in the penetration tape of the insulation tape and separator. In addition to that the batteries were also missing insulation tape.
Samsung worked with UL, Exponent and TUV Rheinland to help with the investigation and they all concluded that the problems lie within the batteries, not the hardware or software.
To prevent this from happening again, Samsung has created an Eight-Point Safety Check as well as a Battery Advisory Group that involves X-ray, durability and OCV testing.
More information can be found at the Samsung Newsroom and the Galaxy Global website regarding the investigation and safety check procedures.
Samsung has been having a really huge nightmare with the Galaxy Note 7 phones exploding and causing disaster to people around the world. Even after doing the recall, a third Galaxy Note 7 exploded in Nicholasville, Kentucky. The owner of the phone is Michael Klering.
The owner told WKYT that he woke up at 4:00 AM to find his bedroom filled with smoke and his phone on fire. Later in the day he went to hospital and was treated with acute bronchitis caused by smoke inhalation.
Klering told WKYT that the phone is the replacement, so it was supposed to be safe. He also added that it wasn’t plugged into anything. The phone was owned for little more than a week.
What is disturbing about this is that the phone caught fire on Thursday and Samsung knew about it and didn’t say anything. And worst of all, this text came from a conversation with Samsung customer support which was supposedly sent to him by mistake.
Just now got this. I can try and slow him down if we think it will matter, or we just let him do what he keeps threatening to do and see if he does it
Samsung asked Klering if they could take the phone but the owner refused, however he did agree to have the phone X-rayed.
That wasn’t the only case of replacement Galaxy Note 7s exploding. One of them caught fire on a Southwest Airlines plane and another in a 13 year girl’s hands in Minnesota.
All major phone carriers in the United States are accepting returns of the phone. Until we hear some better news, Gamenology strongly suggests to avoid buying the phone and if any concern of the safety of the phone, return it to the retailer for a new phone.

Samsung has today announced their newest flagships, the S7 and the S7 edge at the Mobile World Congress 2016.
For starters the design of the phone hasn’t changed much from their earlier flagships, the S6 and the S6 edge(+). But it packs in some stuff people were wanting for a long time, as well as some new and returning features.
The two features that have returned are the microSD card slot, which supports up to 200 GB expandable storage, and the IP68 water certification. The SIM tray is a hybrid, which means you can put in your nano SIM and a microSD card in the same tray.
The phones are powered by Qualcomm’s Snapdragon 820, or in some regions the Samsung Exynos 8890. Both phones come with 4 GB RAM, 32 or 64 GB of storage, and a “Dual Pixel” 12 MP camera. The screen on the regular S7 is 5.1 inches while the screen on the S7 edge is 5.5 inches. Both screens use Super AMOLED technology with a resolution of 2560×1440. The mobile radios are LTE Category 9.
We were disappointed to find out that the 128 GB option is not available this year, as well as the 64 GB model being limited to a few countries/regions.
The S7 has a 3000 mAh battery while the S7 edge packs in a 3600 mAh battery. Both phones use microUSB instead of USB Type C, and feature an “Always On Display” which we really need to look into this further. It feels kind of gimmicky right now, as it may affect battery life. But since the screen is Super AMOLED, it shouldn’t use much battery, but again we have to see how it performs in the long run.
The S7 and S7 edge will be available on March 12. However both phones will be available to purchase early in the UK on March 10.
