The company said all the devices it's planning to release this year were designed and manufactured after the Note 7 recall and have been tested according to new measures put into place since then.
That includes the Galaxy S8 expected to be released this spring. Samsung mobile communications president DJ Koh said at a press conference in Seoul the S8's release schedule was not "meaningfully" affected by the Note 7 issues.
Samsung used two separate battery suppliers for the device, and the initial problems were caused by a design flaw found in only one of those batteries, which it called Battery A.
Following the first recall Samsung stopped using Battery A and instead increased its order from the second supplier. But in its efforts to vastly expand production that supplier introduced a separate flaw into Battery B that also caused the batteries to overheat.
The design flaw in Battery A was an external casing that was too small and didn't allow the battery to expand and contract during charge and discharge cycles. As a result the positive and negative electrodes came into contact, causing a short-circuit, Samsung said.
The initial samples of Battery B were not flawed, but after Samsung ordered about 10 million new units, the battery maker introduced errors including protrusions that were left over from the ultrasonic welding process.
Those errors also caused a short-circuit.
