To troubleshoot a Samsung Galaxy tablet, start with restarting the device by turning it off then back on. This action typically fixes most of the major issues with the Galaxy.
There are a number of common issues that users of the Samsung Galaxy run into, but many have solutions. For instance, if the Samsung Galaxy tablet is having issues connecting to the Internet, it may have to do with changes to the cellular signal. To fix this, the best advice is to wait to see if the signal comes back. Many times, the signal comes back after a couple of minutes. If it does not, consider changing locations until a signal is available.
If the issue is due to poor Wi-Fi, consider checking the connection through the settings or asking the owner of the connection to reset it. Some Wi-Fi networks have limits on the amount of time that a device can have a connection. Once this time is up, the network disconnects the device. To fix this problem, turn off the Wi-Fi on the Galaxy, and then turn it on again.
Some Galaxy tablet devices play music while the owner of the tablet does other things. Though many like this feature, turning it off is difficult. To pause the music, it is necessary to hit the pause button when the pop-up notifications appear.
