“What you don’t know won’t hurt you” is a common phrase that unfortunately does not apply to the apps on your phone. It turns out that thousands of apps on Android and iOS secretly have ads in them that you can’t see, and they very well might be what’s causing a number of problems that plague smartphones today.

The two top smartphone vendors continue to rule the roost.

Looks like Samsung and Apple pretty much own the smartphone market, though there are some scrappy contenders starting to make headway.

According to International Data Corporation (IDC), handset makers shipped a total of 337.2 million smartphones worldwide in the last quarter of 2015 (Q2). This is up 11.6 percent from last year, an amazing bit of growth considering how many smartphones are already on the loose.

The carrier that’s built up quite an army of discontent from its customers over the years probably didn’t win over anyone with its latest announcement. AT&T is raising its upgrade fees for postpaid customers and tacking on a weird, unnecessary activation fee for new AT&T Next customers.

A number of Silicon Valley technology giants have backed Samsung in its legal battle against Apple. Documents confirm Dell, eBay, Facebook, Google, and HP all took the South Korean company’s side in a “friend of the court” brief on July 1.
