Samsung says it has fixed the Galaxy Fold, Bloomberg News reported. The device was beset with problems when it went to reviewers.

The world’s largest smartphone maker is now in the final stages of producing a commercial version but can’t yet pin down a date to begin sales, people familiar with the matter said, asking not to be identified describing an internal effort. Samsung pulled the device after several publications including Bloomberg News reported problems with test versions, such as screen malfunctions that emerged after a film on the display was peeled off… It re-engineered the hinge, pushing it slightly upward from the screen (it’s now flush with the display) to help stretch the film further when the phone opens.

TikTok, the social app popular with younger users, is under investigation for the way it handles personal data. UK authorities are looking into whether it prioritizes protecting children who use it, reported The Guardian.

Elizabeth Denham, the information commissioner, told a parliamentary committee the investigation began in February, prompted by a multimillion-dollar fine from the US Federal Trade Commission (FTC) for similar violations. “We are looking at the transparency tools for children,” Denham said on Tuesday. “We’re looking at the messaging system, which is completely open, we’re looking at the kind of videos that are collected and shared by children online. We do have an active investigation into TikTok right now, so watch this space.”
