Irregularities in battery size were the likely cause of Note 7 fiasco

Was the thinness of the phone a contributing factor?

However, following an increasing number of reports of the phone exploding or catching fire, the firm later issued a global product call and ceased making the Note 7 altogether.

The company halted sales of the device and announced an unprecedented recall of the Note 7 for a second time in response to cases of the handset catching fire. Recalls of the phone cost Samsung billions, essentially forcing them to completely write off a high-end phone.

Yet further analysis of the batteries produced by the two groups has found the different faults that led to the same problem. According to the report, Sammy made a decision to increase production on batteries to make up for the faulty units then things took a turn for the worse.

Additionally, the Journal reports, after the production of replacement phones was quickly ramped up, new flaws in the manufacturing process cropped up at a factory run by Amperex Technology Ltd., another battery manufacturer. "It wasn't clear what the manufacturing issues were", and perhaps this is an area of the investigation that might be revealed on Sunday.

Samsung finally has solved the mystery of its exploding-phone disaster last fall: the batteries didn't fit right. The company has also laid out an 8-step plan including more testing, inspections and manufacturing quality assurance to ensure that the issue won't happen again. Furthermore, the FAA lifted its requirement for airlines to announce the ban to passengers before takeoff, though the device is still prohibited on flights.

On January 2 Patently Apple posted a report titled "Note7 Probe Results due this Month While Samsung Admits that Growth will lag in 2017 Due to Tough Competition". The press conference will conclude the explosions and other technical details in the Galaxy Note 7.

Samsung has lost a ton of money because of the Note 7 debacle-but more than that, it has lost consumer trust.
