I purchased the IDEOS S7 tablet a year or so ago. Up to this point rthere have been NO official updates from Huawei. There support deportment continually refers you to the dL page. There does seem to an update for the Pacific region, but yu need to root your device and be fairly technical to update the tablet. My warning to consumers is that if you purchase their products don't expect any upgrades, so make sure it does everything you need out of the box.
I do like the IDEOS S7 tablet for the replaceable battery since the wall or car chargers are hard to find and the battery life is only a few hours. I purchased a charger and extra batteries to solve my issues.
