Final answer:
Yes, a factory reset can be used for troubleshooting a malfunctioning phone, but simpler methods like restarting the phone or turning off WiFi and Bluetooth should be tried first.
Step-by-step explanation:
It is indeed true that you can factory reset a phone for troubleshooting if it is not working correctly. This process is similar to turning off a computer and turning it back on; it can help resolve issues with the phone's software. Prior to performing a factory reset, it is advised to try simpler methods such as restarting the phone, turning off WiFi, or turning off Bluetooth. These steps can often resolve minor glitches without the need to erase all data from the device. If the problem persists after these initial steps, a factory reset might be necessary; however, it should be performed with caution as it will delete all data on the phone, and a backup should be made beforehand if possible.
