For Amazon, the Kindle Fire has been a huge success in the 7-inch tablet category. For the past two years Amazon’s device has competed with the largest mobile industry players – Apple and Samsung. Now, with Amazon preparing to announce its updated Kindle Fire lineup, news has come that Amazon’s hold on the tablet market may be slipping.

Analyst firm Jumptap this week released data showing that the Kindle Fire has lost 11.4% of its tablet market share over the past year. This is at the same time Samsung has begun to roll into the tablet market in a big way, with its Galaxy Tab devices rising 5.8% in tablet market share year-over-year.

“Previously, the iOS vs. Android battle could not crown a standing victor for Android,” said Matt Duffy, VP of marketing at Jumptap. “Yet in the past year, we’ve seen Samsung rise above the pack in both tablet and smartphone share.”

Jumptap’s new report also held other surprising (and some not-so-surprising) findings from the mobile world. The iPhone is still the world’s top smartphone, at the expense of HTC, Blackberry, and Apple’s own iPod Touch devices, though Samsung’s Galaxy smartphone lineup is gaining traction. Also, apps are now a larger part of the mobile experience than ever before. Jumptap estimates that 84% of mobile traffic is now from apps, up from just 50% two years ago.
