How can Android phones be completely muted? Including media, systems, notifications, alarm clocks and telephone messages. Model: Lenovo A790e system: 2.3.5 Media sound

Hello, I'm glad to answer your question.

Media voice does not include telephone messages, and there is no alarm clock when the A790e is turned off. It's no harm to turn off the phone often, but it's not good to keep it on. It is best to turn off the phone once a week and let the phone rest completely. Flight mode has nothing to do with sound. Mobile phone flight mode is also called aviation mode, which means that the mobile phone must be turned off during flight to avoid the influence of the transmission and reception of mobile phone signals on aircraft flight. Airplane mode is harmless to mobile phones, but I didn't receive text messages or phone calls during that time. And the flight mode has nothing to do with the alarm clock ~

I wish you a successful use. If you have any questions, please ask. If you succeed, please choose me as the best answer. Thank you.
