Android tablets have never been considered the best options on the market, but according to the International Data Corporation, they're not the only ones performing worse than they did in years past. Across the board, tablets aren't leaving store shelves the way they used to.

In the fourth quarter of 2015, otherwise known as holiday season, IDC asserts that 65.9 million units shipped worldwide. This was a 13.7% drop compared to the same period in 2014. 206.8 million devices sold in the entire year, down 10.1% from 230.1 million the year before.

The top five players in the fourth quarter were Apple, Samsung, Amazon, Lenovo, and Huawei, in that order. Despite being in first, Apple sold 24.8% fewer iPads in Q4. Samsung, by comparison, saw a drop of 18.1%. Amazon's story stands in stark contrast to them both. The online retailer sold 175.7% more tablets this holiday season than the one before. This has everything to do with the latest Fire costing only $50. Huawei too had an impressive showing with a 124.6% rise.

Apple, Samsung, Lenovo, Asus, and Huawei were the top sellers for the year as a whole. Apple still saw a 21.8% decline, and Samsung followed with 16.1%. Asus was the biggest loser with a 39.9% drop. Lenovo managed to increase sales by 0.4%, while Huawei jumped up a significantly larger 116.6%. Apple sold 49.6 million tablets compared to Samsung's 33.4 million. Huawei doubled its numbers from 3 million in 2014 to 6.5 million in 2015.

On the positive side, detachable tablets had a relatively strong showing. Apple sold over two million iPad Pros, and more people bought a Surface Pro than a Surface 3 from Microsoft. While Lenovo, Huawei, and Amazon fight for the low-end of what appears to be a shrinking market, Apple and Microsoft are finding that consumers are willing to pay more for tablets that could potentially replace their laptops. It's not clear if IDC counts the Pixel C in this category, but the device unsurprisingly didn't sell enough units to get more than an indirect mention.

"This quarter was unique as we had new detachables in the market from all three of the major platform players. Despite lukewarm reviews, the iPad Pro was the clear winner this season as it was the top selling detachable, surpassing notable entries from Microsoft and other PC vendors. It's also important to note that the transition towards detachable tablets has presented positive opportunities for both Apple and Microsoft. However, Google's recent foray into this space has been rather lackluster as the Android platform will require a lot more refinement to achieve any measurable success."
