There have been numerous complaints about the stability of the stock release at the Thrive Forum, however. For other countries, the latest official version of Android available from Toshiba for this device is still 3.2.1. The Thrive is rarely found new from U.S. retail outlets, although refurbished and used units are popular. Toshiba's Excite series of tablets was the successor to the Thrive series, launched on March 6, 2012, with 7.7-inch, 10.1-inch and 13-inch versions. Upgrades to Android 4.0.4 were available in August 2012. The Excite has also been discontinued by Toshiba, with refurbished and used units available from a variety of sources.
