Trying to factory reset my RCA Viking Neptune 10 tablet it has no volume button, no home button, only a power on button and detachable keyboard. Any suggestions are truly appreciated!
As wbogacz suggested i found the user manual and found out that there is a reset button which can be located at number 9 of the following image of the backside of the device:
Press that button to reset the tablet (then press and hold the Power button for 4~5 seconds to turn on the unit).
Hope this solved your query.
