Samsung said it has now received around 60 percent of recalled Galaxy Note 7 smartphones sold in South Korea, the USA and Europe.

The Korean giant said it is focused on replacing all affected devices “as quickly and efficiently” as possible and reiterated its request that customers affected by the current recall should power off their devices and turn them in.

The world’s top smartphone maker announced on September 2 a global recall of at least 2.5 million Note 7 smartphones in 10 markets due to faulty batteries causing some phones to catch fire. The company says replacement devices it began issuing in mid-September use safe batteries.

The nearly month-long recall process has provided additional stumbles and embarrassment for the company. Reports of Note 7 fires and damages have continued after the recall announcement, while aviation authorities around the world issued warnings or outright bans on the use or charging of the Note 7 on aircraft.
