IrisTab

The irisTab is a tablet computer that was distributed and produced by iriSoft Corporation. It is the 3rd most popular tablet computer, which is praised for its good game support, OS capabilities and battery life. In 2012, iriSoft marketed it to people who browse the web and read e-books often. However, after the tablet series got more powerful, the marketing to different types of people was expanded.

2012
On January 30, 2012, iriSoft announced the irisTab on an event. Pre-orders started on January 31, 2012 and later fully released on February 2, 2012. The tablet had amazing specs for 2012 standards, a Cortex A9 CPU clocked at 1 GHz, 1.5GB of RAM, and 16 or 32 GB of NAND flash storage, and a starting price of $429. It was praised on day one for its fast performance and great software. The tablet's OS can be upgraded from ecOS Touch 1 to ecOS Touch 3.

2013
On May 10, 2013, iriSoft announced a second generation irisTab, named irisTab 2. It had improved performance, with a dual core Qualcomm Snapdragon MSM8960T CPU with an Adreno 320 GPU, 2GB of LPDDR2 RAM, and an expanded storage capacity for up to 64GB, so the tablet can store more applications, but also run faster with its 1.7 GHz clock speed. It sold more units than the first generation, with over 29 million. The tablet's OS can be upgraded from ecOS Touch 2 to ecOS Touch 5, when software updates for the model were discontinued in 2016.

2015
On July 7, 2015, iriSoft announced the 3rd generation irisTab, named irisTab 3. It had a custom octa core Snapdragon 615 that didn't have a built-in modem but can connect to Wi-Fi, 3GB of RAM, a higher resolution 16:10 display thanks to the improved GPU that can support higher resolutions, and up to 128 GB of flash storage. It was highly praised due to its display and how it was 2x faster than the previous generation. The tablet's OS on the 2015 revision can go up from ecOS Touch 4 to Iris OS Touch 7, with the same 3 year software update support.

2017
On September 27, 2017, the irisTab 4 was announced. With a Qualcomm Snapdragon 660 with a external Wi-Fi modem, 4GB of RAM, a 2.2GHz CPU, and a Adreno 512 GPU, it was indeed faster than the previous generation. iriSoft also said in the event that this model had an "all-day battery life", but when the device was later released in October 1, 2017, it could only last 4 hours on video playback, and 2.1 hours on mixed usage, way less than the irisTab 3. The company received a lot of criticism for the scam, and 12 days after the launch, Iris OS Touch 6.0.1 was released, which fixed a severe software bug in the Cornea kernel that caused excessive battery usage. The irisTab 4's OS can go from ecOS Touch 6 to Iris OS Touch 9, with update support ending in 2020.
