Hi Carl, I'm not sure which way you are using to factory reset your tablet but the steps I provide should help with factory resetting it successfully: - Turn Off your Samsung Galaxy Note 10.1 device. - Wait for 10 seconds, Then move to the next step. - Press and hold Volume Up key + Power key. - Keep pressing the above keys until the Samsung Logo appears,Then release Power key only. - When you see Factory reset / System Recovery menu on screen release the Volume Up Key. - Use Volume Down key to select Wipe Data / Factory Reset option. - Use Power key to confirm the operation. - You need to use the Volume Down key again to select "Yes -- delete all user data" - Use Power key to confirm. - After performing the hard reset, Select Reboot System Now option, And confirm it using Power key. - Wait for it to be fully on and then you can start using it.
Go to settings on your tablet, under “personal”, click on accounts, then click on the account you wish to delete. Once in that account click on the 3 vertical dots on the top right corner of the screen and select “remove account”
In most Android phones you can find your files/downloads in a folder called 'My Files' although sometimes this folder is in another folder called 'Samsung' located in the app drawer. You can also search your phone via Settings > Application Manager > All Applications.
