Hi, I have a lenovo a3500-f tablet. recently my storage seems to have broken. It has 16 gb of storage, but now when i go to storage it only shows 8gb of storage capacity all taken up by system memory?? All apps keep closing and failing to launch. If I look below the total breakdown bar and look into apps it opens and still shows 13 gb available. I am having trouble locating a similiar problem online. I have tried what I can including a full factory reset and erasing all my existing data. Still not working... Any thoughts or advice is appreciated.
