(AP) — Facebook CEO Mark Zuckerberg says fixing the company’s problems will take many years.

In a conference call with reporters Wednesday, Zuckerberg said he wishes he could snap his fingers and solve everything in three to six months. But, he said, “these are big issues” and a big shift for Facebook.

That says, he says the company will have “turned a corner” on a lot of these issues by the end of the year.

Zuckerberg has set fixing Facebook as his personal challenge for 2018.

The issues Facebook needs to address go beyond the privacy scandal involving Trump-affiliated consulting firm Cambridge Analytica. Facebook also has been dealing with fake news, the use of Facebook to spread hate and discord and concerns about social media’s effect on people’s mental well-being.

Among the latest changes: Facebook is restricting access that apps can get about users’ events, as well as information about groups such as member lists and content.

In addition, the company is also removing the option to search for users by entering a phone number or an email address. While this helped individuals find friends who may have a common name, Facebook says businesses that had phone or email information on customers were able to collect profile information this way.

 

Facebook says as many as 87 million people may have had their data accessed in the Cambridge Analytica scandal — an increase from the 50 million disclosed in published reports.
