Over the last couple of years over 1 million people have tested their Android phone with my Phone Check and Test app. During this time I have had a large number of questions from people. I decided to write a summary of how a cell phone works in relation to the most common questions.
How a cell phone works
- Operating System
- Memory and Storage
- Telephone network and phone signal
- Bluetooth, NFC, and IR
- Location and GPS
I have 20 years experience working in cell phone operator engineering and phone/computer test software. If you would like me to add an overview of an aspect of how a phone works, please send me an email, firstname.lastname@example.org and I will investigate and add information to my website. Thanks.
