What is airplane mode? How to turn it on? Answer: Flight mode is also called aviation mode. Simply put, it is the mode used when an airplane is flying. If you use a mobile phone while flying, it will interfere with the signal and endanger aviation safety! Therefore, relevant aviation regulations prohibit the use of mobile phones on airplanes. But if your phone turns on airplane mode, you can turn off all network functions so that there will be no signal interference. Since turning on airplane mode can turn off all network functions, the phone can gain more operating space. When you need to run some large programs (such as some games), using airplane mode can allow the program to run normally. (Generally, a mobile phone cannot perform any operations without a SIM card). In S60, os6 mobile phones can use sTools to turn on airplane mode. Enter sTools, choose to turn on airplane mode, turn off the phone, remove the sim card, and turn on the phone to enter airplane mode. Os7 mobile phones cannot be turned on. Os8 and later mobile phones come with offline mode, which is equivalent to airplane mode. Why does the memory card I bought show only 490M instead of 512M?
