Until Microsoft takes the reigns and gives users the ability to delete temporary files (not to be confused with the “other storage” issue), it looks like OEMs will continue to have to offer a solution. Nokia was the first to do with their Storage Check application and now Huawei looks poised to do the same for their Ascend W1 and W2 devices.
The site WP7Forum.ru have produced a screenshot of the supposed upcoming app, noting that it’s not too far off from being released (presumably to their branded Store). It’s not clear if Huawei, like Nokia, will have to have a corresponding firmware update to enable the feature or it’s already there.
Regardless, it’s nice to see other companies offer something to their customers, though we wish HTC and Samsung would jump on board too.
