Amazon has allowed bargain-basement Android smartphone maker Blu to resume listing a number of its models that were suspended from the website last week in a row over covert data collection.
Blu maintained that the collection of smartphone data, which appeared to be relayed to servers based in China, was "standard for OTA functionality" and "does not affect any user's privacy or security".
These explanations have satisfied Amazon, even if they might concern users. Amazon has therefore allowed the company to put the offending devices back on sale.
Amazon suspended sales from Miami-based manufacturer Blu only last week following the claims made last week.
It came after security company Kryptowire had demonstrated that the silent background data harvesting in operation on Blu devices was terminating at a company called Shanghai Adups Technology, a company that offers Firmware Over The Air (FOTA) services.
While that might be a legitimate activity, the level of data slurping claimed by Kryptowire raised eyebrows.
Indeed, Adups has been accused in the past of planting spyware on devices, along with back doors, to make getting more data in and out easier.
Moreover, Blu isn't a first time offender. It was first suspended last October when its Blu R1 HD was found sporting exactly the same tracking software.
At the time, Blu said it was a "mistake" and removed the software, along with the same software from the Life One X2 model it was also hidden in. Sometimes the system was even sending SMS messages.
This time, however, the same security company found the same firm using the same company's spyware in more expensive models of phone stocked by the same retailer.
This time, they claimed to have found the software collecting cell tower data and even more personal ID.
A statement to CNET last week from Amazon said: "Because security and privacy of our customers is of the utmost importance, all Blu phone models have been made unavailable for purchase on Amazon.com until the issue is resolved."
