my tab is not gettimg factory reset

[AC Question]

My tab is not getting factory reset even during boot time ,also if I delete something from main memory the next time I turn it on it reappers,same is true for something I download and save in main memory.No app is getting updated and now nothing is being downloaded .when I do factory reset the tab simply turns off and turns on .
