Data saved to a Tesco Hudl tablet is vulnerable to recovery, even after a factory reset, according to new research.
The BBC has reported that three separate investigations of Android’s data deleting systems have found that it’s possible to recover information thanks to a bug in the Hudl’s Rockchip processor.
The investigation used second-hand tablets sold via auction sites such as eBay and found that in some cases a factory reset just removed the list of where data was stored.
With the Hudl, it is possible to retrieve saved data from the onboard memory.
Tesco’s response to the news was as follows: "Customers should always ensure all personal information is removed prior to giving away or selling any mobile device. To guarantee this, customers should use a data wipe program."
Tesco launched the Hudl tablet in 2013, in it’s first three months the device sold more than 300,000 units.
The Hudl 2, along with Tesco’s first own-brand smartphone, is expected to launch before the end of the year.
