If you are trying to update your tablet and it keeps freezing when you are attempting to update it, your tablet probably has too much space taken up for the new update to install. Try removing things from your tablet to free up some space to allow the update to install successfully. For more information, refer to our troubleshooting page: Polaroid S10 Troubleshooting
The micro USB port on the tablet is not specified as the charging port. Rather, the smaller round port to the immediate left of the micro USB port is the designated charge port for the Polaroid S10 tablet. Try plugging the charge cable associated with that port into the tablet and see if the tablet charges once it is plugged into a power source.
