SmartQ, an experienced Android tablet maker from mainland China, has released Android 4.1.1 Jelly Bean firmware updates for all of its current tablets. Previously, the devices shipped with Android 4.0.4 Ice Cream Sandwich but the company has been quick to release Jelly Bean and bring the advantages of the better notification system and Google Now to its customers.
SmartQ has a full range of tablets starting with the smaller seven inch S7 and K7 models and finishing with the 10.1 inch T30. In between, there is an eight inch model and a couple of 9.7 inch models. The prices are competitive with the eight inch dual core Q8 selling for just $129.
Upgrading is simple enough. Download the firmware from the company's international website (which is in English in case your Mandarin isn't up to scratch) and copy a single file onto the SD card. Then reboot while pressing the volume down key and the device will automatically upgrade. I have done this myself a couple of times on an S7 and the process works flawlessly.
