If you still have a Samsung Note7 in Australia, here's what to do

So that's that.

On Tuesday local time, Samsung halted sales and exchanges of its ill-fated Galaxy Note7 smartphone until further notice.

In a statement, the company cited customer safety as its "top priority." Samsung is investigating reports of ongoing battery problems with replacement Note7 devices, although it has not indicated what could be the cause of the issue.

There have been at least five alleged incidents where the replacements dangerously overheated and combusted -- the very issue they were meant to eliminate.

Samsung advised Note7 owners, both those with an original Note7 or replacement Note7, to turn off the device and stop using it.

Samsung Australia told Mashable in a statement it's working with partners to ensure exchanges are available, including a Galaxy S7 or S7 edge, or a full refund for the Galaxy Note7.

"Before returning their Galaxy Note7, customers should back-up their data, complete a factory reset to delete personal information and power down their device," it reads. "We sincerely regret the inconvenience caused to our Australian customers and thank them for their patience."

If you still have an original Note7 (why oh why?) or a replacement device, here are what major telco companies advise:

For Vodafone customers:

Vodafone is pausing its Note7 replacement program, a spokesperson told Mashable. "Customers are encouraged to back-up their data, complete a factory reset to delete all personal information, power-down their device and exchange it at any Vodafone branded store."

Customers with the devices can exchange it for a Samsung Galaxy 7 Edge "or another smartphone in stock of equal or less value."

For Telstra customers:

While Samsung investigates the reported replacement Note7 incidents in the U.S., Telstra has temporarily paused shipping replacements, a spokesperson told Mashable.

"In the meantime we are helping customers with loan phones and for those who do not wish to wait for the exchange program a change-over to an alternative smartphone," he said. "Telstra customers returning their Galaxy Note 7 will be offered a loan phone (Samsung J1 Mini or Samsung Galaxy 7 Edge) or as stated a change-over to an alternate smart phone."

For Optus customers:

Optus is also advising customers to turn off replacement Note7 devices.

"Optus customers who are waiting to receive a replacement Note7 device, or have already received a replacement Note7 device, can select between a Galaxy S7 Edge or Galaxy S7 as a replacement device," a spokesperson told Mashable. "We can also supply alternative handsets for customers who wish to change from Samsung devices."

Mashable has approached Optus for details and will update as soon as possible.
