The demand was also fed by dealers who provided financial incentives on devices and data to push tablet purchases, the company said in a blog post.
The leading tablet sellers all increased their sales due to the surge in demand and achieve shipments that are normally seen in the holiday season in the fourth quarter.
Apple's iPad shipments increased by 20% to take the top spot among tablet vendors, with more than 14 million units shipped.
“Tablets enjoyed a renaissance in Q2 2020 because the devices tick so many boxes for remote work and education use,” said Canalys analyst Ishan Dutt.
“The ability to collaborate virtually as well as view and interact with digital content has become paramount, especially in the education space. The coronavirus pandemic has increased competition for communal screen access between household members forced to stay indoors.
"Tablets help overcome this problem by allowing each family member to have their own device. And they are more budget-friendly than desktops and notebooks.
"For users with greater productivity needs, the proliferation of detachable tablets has been a boon. These devices have gained traction as primary devices for work and it is vital to include them when evaluating the PC market as a whole. Apple and Lenovo’s recent success shows that having a tablet offering as a mainstream PC vendor is invaluable.”
Canalys senior analyst Ben Stanton said: “The channel and carrier ecosystem around tablets has also played a significant role in this stellar Q2 performance.
“Vendors and retailers in mature markets have offered massive discounts as part of their back-to-school promotions. They have also ramped up their capacity to manage online sales and delivery in the face of lockdown measures.
"Carriers have also taken important steps beyond just providing devices. For example, in the United States, AT&T offered 60 days of unlimited wireless data service for education-issued tablets to qualifying schools nationwide. In many mobile-first markets in Asia Pacific, where 4G connectivity is often cheaper and more reliable than broadband, having a wide range of connected tablet options has been vital to ensure remote education is possible.”
