Troubleshooting mobile devices is not so different than PCs. One example is short battery life. Always check to make sure your brightness setting is not maxed out, as this will drain battery quickly. Also make sure you are not running multiple applications simultaneously. This will also drain your battery life. Another example is a malfunctioning speaker. One possible issue is that the sound settings are turned all the way down. Another issue is that the speaker is not configured properly. If neither of those solve the issue, it is possible that the speaker itself has malfunctioned and needs replaced.
